GENERAL INFORMATION
GENERAL PRECAUTIONS
Synthetic rubber
Dangerous substances
WARNING: Many ’O’ rings, seals, hoses,
flexible pipes and other similar items
which appear to be natural rubber, are in
fact, made of synthetic materials called
Fluoroelastomers.
Under normal operating conditions this material
is safe and does not present a health hazard.
However, if the material is damaged by fire or
excessive heating, it can break down and
produce highly corrosive Hydrofluoric acid
which can cause serious burns on contact with
skin.
WARNING: Many liquids and other
substances used in motor vehicles are
poisonous and should not be consumed
under any circumstances.
As far as possible, try to prevent skin contact
with any potentially harmful materials.
Substances to be treated with particular caution
include (but is not limited to): acid, anti-freeze,
asbestos, brake fluid, fuel, windscreen washer
additives, lubricants, refrigerant and various
adhesives.
Always read the instructions printed on labels or
stamped on components carefully.
Such instructions should be strictly complied
with; they are included to ensure your health and
personal safety is not compromised through the
incorrect use of the materials to which they
relate.
If skin contact does occur:
• Remove any contaminated clothing immediately.
• Irrigate effected area of skin with a copious
amount of cold water or limewater for 15 to 60
minutes.
• Obtain medical assistance immediately
Should any material be in a burnt or over-heated
condition, handle with extreme caution and wear
protective clothing (seamless industrial gloves,
protective apron etc.).
Decontaminate and dispose of gloves immediately
after use.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
1
GENERAL INFORMATION
Engine oils
• Do not use petrol, kerosene, diesel fuel, gas,
oil, thinners or solvents for cleaning skin.
WARNING: Prolonged and repeated
contact with mineral oil can result in the
removal of natural fats from the skin; this
may cause dryness, irritation and dermatitis.
• If skin disorders develop, obtain medical
advice without delay.
In particular, used engine oil contains potentially
harmful carcinogenic contaminants. Adequate
means of skin protection (barrier creams etc.)
and washing facilities must be provided.
• Wear eye protection (e.g. goggles or face
shield) if there is a risk of eye contamination.
Eye wash facilities should be provided in the
close vicinity of the work area.
Avoid excessive skin contact with used engine
oils and always adhere to the following health
protection recommendations:
Environmental Protection Precautions
Health Protection Precautions
• Avoid prolonged and repeated contact with
oils, particularly used engine oils.
• Wear protective clothing, including
impervious gloves where practicable.
• Do not put oily rags in pockets.
• Avoid contaminating clothes (particularly
underpants) with oil.
• Overalls must be cleaned regularly. Discard
heavily soiled clothing and oil impregnated
footwear.
• First aid treatment should be obtained
immediately for open cuts and wounds.
• Where practicable, degrease components
prior to handling.
It is illegal to pour used oil on to the ground, down
sewers or drains, or into water courses.
Burning of used engine oil in small space heaters or
boilers should only be considered for units of
approved design and in compliance with the
equipment manufacturer’s recommendations. The
heating system must meet the regulatory standards
of HMIP for small burners of less than 0.4 MW. If in
doubt check with the appropriate local authority
and/or manufacturer of the approved appliance.
Dispose of used oil and filters through authorised
waste disposal contractors and licensed waste
disposal sites, or through the waste oil reclamation
trade. If in doubt, contact the Local Authority for
advice on disposal facilities.
• Use barrier creams: apply before each work
period to help removal of engine oil from the
skin.
• Wash with soap and water to ensure all oil is
removed (propriety skin cleansers and nail
brushes will help).
• Use moisturisers after cleaning; preparations
containing lanolin help replace the skin’s
natural oils which have been removed.

GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
GENERAL INFORMATION
Precautions against damage
SAFETY INSTRUCTIONS
CAUTION: Always fit wing and seat covers
before commencing work. Avoid spilling
brake fluid or battery acid on paintwork;
immediately wash off with water if this occurs.
Whenever possible, use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
Jacking
CAUTION: Disconnect the battery earth
lead before starting work, see
ELECTRICAL PRECAUTIONS.
CAUTION: Always use the recommended
service tool or a satisfactory equivalent
where specified.
The recommended jacking points are shown in the
LIFTING AND TOWING sub-section of the
INFORMATION section.
Always ensure that any lifting apparatus has
sufficient load capacity for the weight to be lifted.
Ensure the vehicle is standing on level ground prior
to lifting or jacking.
Apply the handbrake and chock the wheels.
CAUTION: Protect exposed bearing
surfaces, sealing surfaces and screw
threads from damage.
WARNING: Never rely on a jack as the sole
means of support when working beneath
the vehicle. Use additional safety supports
beneath the vehicle.
Do not leave tools, lifting equipment, spilt oil,
etc., around or on the work bench area. Always
keep a clean and tidy work area.
Brake shoes and pads
WARNING: Always fit the correct grade
and specification of brake linings.
When renewing brake pads and brake
shoes always replace as complete axle sets
only.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS

GENERAL INFORMATION
Brake hydraulics
WARNING: It is imperative that the correct
brake fittings are used and that threads of
components are compatible.
• Always use two spanners when loosening or
tightening brake pipe or hose connections.
• Ensure that hoses run in a natural curve and are
not kinked or twisted.
• Fit brake pipes securely in their retaining clips
and ensure that the pipe run cannot contact a
potential chafing point.
• Containers used for hydraulic fluid must be kept
absolutely clean.
• Do not store hydraulic fluid in an unsealed
container, it will absorb water and in this
condition would be dangerous to use due to a
lowering of its boiling point.
• Do not allow hydraulic fluid to be contaminated
with mineral oil, or use a container which has
previously contained mineral oil.
GENERAL FITTING INSTRUCTIONS
Component removal
Whenever possible, clean components and
surrounding area before removal.
• Blank off openings exposed by component
removal.
• Immediately seal fuel, oil or hydraulic lines when
apertures are exposed; use plastic caps or plugs
to prevent loss of fluid and ingress of dirt.
• Close open ends of oilways exposed by
component removal with tapered hardwood plugs
or conspicuous plastic plugs.
• Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
• Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
• Do not re-use fluid from the system.
• Always use clean brake fluid or a recommended
alternative to clean hydraulic components.
• Fit a blanking cap to an hydraulic union and a
plug to its socket after removal to prevent the
ingress of dirt.
CAUTION: Absolute cleanliness must be
observed with hydraulic components.
Engine coolant caps and plugs
WARNING: Extreme care is necessary
when removing engine coolant caps and
plugs when the engine is hot and
especially if it is overheated. To avoid the
possibility of scalding allow the engine to cool
before attempting coolant cap or plug removal.

GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
GENERAL INFORMATION
Dismantling
Cleaning components
Observe scrupulous cleanliness when dismantling
components, particularly when brake, fuel or
hydraulic system parts are being worked on.
Always use the recommended cleaning agent or
equivalent.
CAUTION: A particle of dirt or a cloth
fragment could cause a serious
malfunction if trapped in these systems.
• Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed during the process.
• Use marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre
punch or scriber to mark parts, they could initiate
cracks or distortion in marked components.
• Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
• Wire labels on to all parts which are to be
renewed, and to parts requiring further inspection
before being passed for reassembly; place these
parts in separate containers from those
containing parts for rebuild.
• Do not discard a part due for renewal until after
comparing it with a new part, to ensure that its
correct replacement has been obtained.
WARNING: Ensure that adequate
ventilation is provided when volatile
degreasing agents are being used.
CAUTION: Do not use degreasing
equipment for components containing
items which could be damaged by the use
of this process.
General Inspection
• Never inspect a component for wear or
dimensional check unless it is absolutely clean; a
slight smear of grease can conceal an incipient
failure.
• When a component is to be checked
dimensionally against recommended values, use
the appropriate measuring equipment (surface
plates, micrometers, dial guages etc.). Ensure
the measuring equipment is calibrated and in
good serviceable condition.
• Reject a component if its dimensions are outside
the specified tolerances, or if it appears to be
damaged. A part may be refitted if its critcal
dimension is exactly to its tolerance limit and it
appers to be in satisfactory condition.
• Use ’Plastigauge’ 12 Type PG-1 for checking
bearing surface clearances.
WARNING: When washing under bonnet,
never direct water onto ECM as water
ingress may occur resulting in damage to
electrical components inside.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
5
GENERAL INFORMATION
BALL AND ROLLER BEARINGS
CAUTION: Never refit a ball or roller
bearing without first ensuring that it is in a
fully serviceable condition.
CAUTION: When hub bearings are
removed or displaced, NEW bearings must
be fitted; do not attempt to refit the old
hub bearings.
• Remove all traces of lubricant from bearing
under inspection by cleaning with a suitable
degreaser; maintain absolute cleanliness
throughout operations.
• Conduct a visual inspection for markings on
rolling elements, raceways, outer surface of outer
rings or inner surface of inner rings. Reject any
bearings found to be marked, since marking in
these areas indicates onset of wear.
• Hold inner race of bearing between finger and
thumb of one hand and spin outer race to check
that it revolves absolutely smoothly. Repeat,
holding outer race and spinning inner race.
• Rotate outer ring gently with a reciprocating
motion, while holding inner ring; feel for any
check or obstruction to rotation. Reject bearing if
action is not perfectly smooth.
• When fitting a bearing to a shaft, only apply force
to the inner ring of the bearing. When fitting a
bearing into a housing, only apply force to the
outer ring of the bearing.
• In the case of grease lubricated bearings (e.g.
hub bearings) fill the space between bearing and
outer seal with the recommended grade of
grease before fitting seal.
• Always mark components of separable bearings
(e.g. taper roller bearings) when dismantling, to
ensure correct reassembly. Never fit new rollers
in a used outer ring; always fit a complete new
bearing assembly.
• Lubricate bearing with generous amounts of
lubricant appropriate to installation.
• Inspect shaft and bearing housing for
discoloration or other markings which indicate
movement between bearing and seatings.
• Ensure that shaft and housing are clean and free
from burrs before fitting bearing.
• If one bearing of a pair shows an imperfection, it
is advisable to replace both with new bearings;
an exception could be if the faulty bearing had
covered a low mileage, and it can be established
that damage is confined to only one bearing.
6
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
GENERAL INFORMATION
OIL SEALS
Always renew oil seals which have been removed
from their working location (whether as an individual
component or as part of an assembly).
• Carefully examine seal before fitting to ensure
that it is clean and undamaged.
• Grease outside diameter of seal, place square to
housing recess and press into position using
great care, and if possible a ’bell piece’ to ensure
that seal is not tilted. Never let weight of
unsupported shaft rest in seal.
NOTE: In some cases it may be preferable
to fit seal to housing before fitting to shaft.
• Ensure the surface on which the new seal is to
run is free of burrs or scratches. Renew the
component if the original sealing surface cannot
be completely restored.
• Protect the seal from any surface which it has to
pass when being fitted. Use a protective sleeve
or tape to cover the relevant surface.
• Certain oil seals are coated with a protective wax
and must be fitted dry unless stated otherwise.
Where an oil seal needs to be lubricated prior to
fitment, lubricate the sealing lips with a
recommended lubricant before use to prevent
damage during initial use. On dual lipped seals,
smear the area between the lips with grease.
• If a seal spring is provided, ensure that it is fitted
correctly.
• Place lip of seal towards fluid to be sealed and
slide into position on shaft. Use fitting sleeve
where possible to protect sealing lip from
damage by sharp corners, threads or splines. If a
fitting sleeve is not available, use plastic tube or
tape to prevent damage to the sealing lip.
• Use the recommended service tool to fit an oil
seal. If the correct service tool is not available,
use a suitable tube approximately 0.4 mm (0.015
in.) smaller than the outside diameter of the seal.
Use an hammer VERY GENTLY on drift if a
suitable press is not available.
• Press or drift the seal in to the depth of its
housing with the sealing lip facing the lubricant to
be retained if the housing is shouldered, or flush
with the face of the housing where no shoulder is
provided. Ensure that the seal does not enter the
housing in a tilted position.
NOTE: Most cases of failure or leakage of
oil seals are due to poor fitting, which can
result in damage to both seals and sealing
surfaces. NEVER use a seal which has been
improperly stored or handled, such as hung on a
hook or nail.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
7
GENERAL INFORMATION
JOINTS AND JOINT FACES
LOCKING DEVICES
Fit joints dry unless specified otherwise.
Tab Washers
• Always use the correct gaskets as specified.
• When jointing compound is used, apply in a thin
uniform film to metal surfaces; take care to
prevent jointing compound from entering oilways,
pipes or blind tapped holes.
• If gaskets and/or jointing compound is
recommended for use; remove all traces of old
jointing material prior to reassembly. Do not use
a tool which will damage the joint faces and
smooth out any scratches or burrs using an oil
stone. Do not allow dirt or jointing material to
enter any tapped holes or enclosed parts.
• Prior to reassembly, blow through any pipes,
channels or crevices with compressed air.
CAUTION: Always release locking tabs
and fit new locking washers, do not re-use
locking tabs. Ensure the new tab washer
is the same design as that replaced.
Locking Nuts
Always use a backing spanner when slackening or
tightening brake and fuel pipe unions.
Roll Pins
Always fit new roll pins of an interference fit in the
hole.
Circlips
Always fit new circlips of the correct size for the
groove.
Locking wire
Always fit locking wire of the correct type. Arrange
wire so that its tension tends to tighten the bolt
heads or nuts to which it is fitted.
Keys and Keyways
• Remove burrs from edges of keyways with a fine
file and clean thoroughly before attempting to
refit key.
• Clean and inspect key closely; keys are suitable
for refitting only if indistinguishable from new, as
any indentation may indicate the onset of wear.
Fitting a split pin
CAUTION: Always fit new split-pins of the
correct size for the hole in the bolt or stud.
Do not slacken nut to enter split-pin.
8
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
GENERAL INFORMATION
SCREW THREADS
BOLT IDENTIFICATION
Metric threads to ISO standards are used.
Damaged nuts, bolts and screws must always be
discarded.
NOTE: Cleaning damaged threads with a
die or tap impairs the strength and
closeness of fit of the threads and is not
recommended.
CAUTION: Always ensure that
replacement bolts are at least equal in
strength to those replaced.
Castellated nuts must not be slackened to accept a
split-pin, except in recommended cases when this
forms part of an adjustment.
Do not allow oil or grease to enter blind threaded
holes. The hydraulic action on screwing in the bolt or
stud could split the housing.
Always tighten a nut or bolt to the recommended
torque figure. Damaged or corroded threads can
affect the torque reading.
An ISO metric bolt or screw made of steel and larger
than 6 mm in diameter can be identified by either of
the symbols ISO M or M embossed or indented on
top of the bolt head.
In addition to marks identifying the manufacturer, the
top of the bolt head is also marked with symbols
indicating the strength grade, e.g. 8.8; 10.9; 12.9;
14.9. As an alternative, some bolts and screws have
the M and strength grade symbol stamped on the
flats of the hexagon.
Encapsulated bolts and screws
To check or re-tighten a bolt or screw to a specified
torque figure, first slacken a quarter of a turn, then
retighten to the correct torque figure.
Oil thread lightly before tightening to ensure a free
running thread, except in the case of threads treated
with sealant / lubricant, and self-locking nuts.
Encapsulated bolts and screws have a
micro-encapsulated locking agent pre-applied to the
thread. They are identified by a coloured section
which extends 360° around the thread. The locking
agent is released and activated by the assembly
process and is then chemically cured to provide the
locking action.
GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
9
GENERAL INFORMATION
Unless a specific repair procedure states otherwise,
encapsulated bolts may be re-used providing the
threads are undamaged and the following procedure
is adopted:
NUT IDENTIFICATION
• Remove loose adhesive from the bolt and
housing threads.
• Ensure threads are clean and free of oil and
grease.
• Apply an approved locking agent.
NOTE: Always fit a new encapsulated bolt
when replacing; or if not available, a bolt
of equivalent specification treated with an
approved locking agent.
Self-locking bolts and screws
A nut with an ISO metric thread is marked on one
face or on one of the flats of the hexagon with the
strength grade symbol 8, 12, or 14. Some nuts with
a strength grade 4, 5 or 6 are also marked and some
have the metric symbol M on the flat opposite the
strength grade marking.
Self-locking bolts and screws, i.e. nylon patched or
trilobular thread can be re-used providing resistance
can be felt when the locking portion enters the
female thread.
Nylon patched bolts and screws have a locking
agent pre-applied to the threads. They are identified
by the presence of a coloured section of thread
which extends for up to 180° around the thread.
A clock face system is sometimes used as an
alternative method of indicating the strength grade.
The external chamfers or a face of the nut is marked
in a position relative to the appropriate hour mark on
a clock face to indicate the strength grade.
A dot is used to locate the 12 o’clock position and a
dash to indicate the strength grade. If the grade is
above 12, two dots identify the 12 o’clock position.
Trilobular bolts (i.e. Powerlok) have a special thread
form which creates a slight interference in the
tapped hole or threads of the nut into which it is
screwed.
CAUTION: DO NOT re-use self-locking
fasteners in critical locations (e.g. engine
bearings, flywheel). Always use the
correct replacement self-locking nut, bolt or
screw.
CAUTION: DO NOT fit non self-locking
fasteners in applications where a
self-locking nut, bolt or screw is specified.

well as causing damage to protective
coatings, there is a risk of damage to electronic
equipment and brake linings from stray heat.
When tightening a slotted or castellated nut, never
loosen it to insert a split pin or locking wire except
where recommended as part of an adjustment. If
difficulty is experienced, alternative washers or nuts
should be selected, or the washer thickness
reduced.
Where self-locking nuts have been removed, it is
advisable to replace them with new ones of the
same type.
• Obtain appropriate plugs or caps before
detaching hose end fittings, so that the ports can
be immediately covered to prevent the ingress of
dirt.
• Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any faulty hoses.
• When refitting a hose, ensure that no
unnecessary bends are introduced, and that
hose is not twisted before or during tightening of
union nuts.
• Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
• Absolute cleanliness must be observed with
hydraulic components at all times.
• After any work on hydraulic systems, carefully
inspect for leaks underneath the vehicle while a

GENERAL PRECAUTIONS AND FITTING INSTRUCTIONS
GENERAL INFORMATION
FUEL HANDLING PRECAUTIONS
Fuel tank drainage
General
WARNING: Petrol/gasoline must not be
extracted or drained from any vehicle
whilst it is standing over a pit.
Draining or extraction of petrol/gasoline from a
vehicle fuel tank must be carried out in a well
ventilated area.
The receptacle used to contain the
petrol/gasoline must be more than adequate for
the full amount of fuel to be extracted or drained.
The receptacle should be clearly marked with its
contents, and placed in a safe storage area
which meets the requirements of local authority
regulations.
The following information provides basic precautions
which must be observed if petrol (gasoline) is to be
handled safely. It also outlines other areas of risk
which must not be ignored. This information is
issued for basic guidance only, if in doubt consult
your local Fire Officer.
Petrol - Gasoline
Petrol/gasoline vapour is highly flammable and in
confined spaces is also explosive and toxic.
When petrol/gasoline evaporates it produces 150
times its own volume in vapour, which when diluted
with air becomes a readily ignitable mixture. The
vapour is heavier than air and will always fall to the
lowest level. The vapour can be easily distributed
throughout a workshop by air currents;
consequently, even a small spillage of
petrol/gasoline is potentially very dangerous.
WARNING: Do not use a pit when
removing fuel system components.
Always have a fire extinguisher containing FOAM,
CO2, GAS or POWDER close at hand when
handling or draining fuel or when dismantling fuel
systems. Fire extinguishers should also be located
in areas where fuel containers are stored.
Always disconnect the vehicle battery before
carrying out dismantling or draining work on a fuel
system.
WARNING: When petrol/gasoline has been
extracted or drained from a fuel tank the
precautions governing naked lights and
ignition sources should be maintained.
Fuel tank removal
When the fuel line is secured to the fuel tank outlet
by a spring steel clip, the clip must be released
before the fuel line is disconnected or the fuel tank is
removed. This procedure will avoid the possibility of
residual petrol fumes in the fuel tank being ignited
when the clip is released.
As an added precaution fuel tanks should have a
’PETROL (GASOLINE) VAPOUR’ warning label
attached to them as soon as they are removed from
the vehicle.
Whenever petrol/gasoline is being handled, drained
or stored, or when fuel systems are being
dismantled, all forms of ignition must be
extinguished or removed; any leadlamps must be
flameproof and kept clear of spillage.
WARNING: No one should be permitted to
repair components associated with
petrol/gasoline without first having
specialist training.
FUEL HANDLING PRECAUTIONS

GENERAL INFORMATION
Fuel tank repairs
Under no circumstances should a repair to any fuel
tank be carried out without first rendering the tank
SAFE, by using one of the following methods:
a. STEAMING: With the filler cap and tank unit
removed, empty the tank. Steam the tank for at least
two hours with low pressure steam. Position the tank
so that condensation can drain away freely, ensuring
that any sediment and sludge not volatized by the
steam is washed out during the steaming process.
b. BOILING: With the filler cap and tank unit
removed, empty the tank. Immerse the tank
completely in boiling water containing an effective
alkaline degreasing agent or a detergent, with the
water filling and also surrounding, the tank for at
least two hours.
After steaming or boiling, a signed and dated label to
this effect should be attached to the tank.
Body repairs
WARNING: When body repairs involve the
use of heat, all fuel pipes which run in the
vicinity of the repair area must be
removed, and the tank outlet plugged, BEFORE
HEAT IS APPLIED. If the repair is in the vicinity
of the fuel tank, the tank must be removed.
Plastic fuel pipes are particularly susceptible to heat,
even at relatively low temperature, and can be
melted by heat conducted from some distance away.
Fuel lines or tanks must not be removed whilst the
vehicle is over an inspection pit.

FUEL HANDLING PRECAUTIONS
GENERAL INFORMATION
ELECTRICAL PRECAUTIONS
Ensure that any protection (covers, insulation etc.) is
replaced if disturbed.
General
The following guidelines are intended to ensure the
safety of the operator whilst preventing damage to
the electrical and electronic components fitted to the
vehicle. Where necessary, specific precautions are
detailed in the relevant sections of this Manual which
should be referred to prior to commencing repair
operations.
Equipment
Prior to commencing any test procedure on the
vehicle ensure that the relevant test equipment is
working correctly and any harness or connectors are
in good condition. It is particularly important to
ensure the propriety of the lead and plugs of mains
operated equipment.
Having confirmed a component to be faulty:
• switch off the ignition and disconnect the battery.
• remove the component and support the
disconnected harness.
• when replacing the component keep oily hands
away from electrical connection areas and push
connectors home until any locking tabs fully
engage.
Battery disconnection
Before disconnecting the battery, disable the alarm
system and switch off all electrical equipment. If the
radio is to be serviced, ensure the security code has
been deactivated.
Polarity
Never reverse connect the vehicle battery and
always ensure the correct polarity when connecting
test equipment.
High Voltage Circuits
Whenever disconnecting live ht-circuits always use
insulated pliers and never allow the open end of the
ht-lead to contact other components - particularly
ECU’s.
CAUTION: To prevent damage to electrical
components ALWAYS disconnect the
battery when working on the vehicle
electrical system. The earth lead must be
disconnected first and reconnected last.
Always ensure that battery leads are routed
correctly and are not close to any potential
chafing points.
Battery charging
CAUTION: Exercise caution when
measuring the voltage on the coil
terminals while the engine is running, high
voltage spikes can occur on these terminals.
Connectors and Harnesses
Only recharge the battery with it removed from the
vehicle.
Always ensure any battery charging area is well
ventilated and that every precaution is taken to avoid
naked flames and sparks.
The engine compartment of a vehicle is a
particularly hostile environment for electrical
components and connectors. Always ensure
electrically related items are dry and oil free before
disconnecting and connecting test equipment.
CAUTION: Ensure disconnected
multiplugs and sensors are protected from
being contaminated with oil, coolant or
other solutions. Contamination could impair
performance or result in catastrophic failure.
Never force connectors apart using tools to prise
apart or by pulling on the wiring harness.
Always ensure locking tabs are disengaged before
disconnection, and match orientation to enable
correct reconnection.
ELECTRICAL PRECAUTIONS
1
GENERAL INFORMATION
Ignition system safety precautions
Grease for electrical connectors
WARNING: Before commencing work on
an ignition system, all high tension
terminals, adapters and diagnostic
equipment should be inspected.
Some under bonnet and under body connectors may
be protected against corrosion by the application of
a special grease during vehicle production. Should
connectors be disturbed in service, or repaired or
replaced, additional grease should be re-applied:
Part No. BAU 5811, available in 150 gm tubs.
Ensure all cables, connectors and components
are adequately insulated and shielded.
Accidental contact with a poorly insulated
ignition system component could result in a
severe electrical shock.
Wearers of surgically implanted pacemaker
devices should not be in close proximity to
ignition circuits or diagnostic equipment.
Disciplines
Switch off the ignition prior to making any connection
or disconnection in the system to prevent electrical
surges caused by disconnecting ’live’ connections
damaging electronic components.
Ensure hands and work surfaces are clean and free
of grease, swarf, etc. Grease collects dirt which can
cause electrical tracking (short-circuits) or
high-resistance contacts.
When handling printed circuit boards, treat with care
and hold by the edges only; note that some
electronic components are susceptible to body
static.
Connectors should never be subjected to forced
removal or refit, especially inter-board connectors.
Damaged contacts can cause short-circuit and
open-circuit fault conditions.
Prior to commencing test, and periodically during a
test, touch a good vehicle body earth to discharge
static charge. Some electronic components are
vulnerable to the static electricity that may be
generated by the operator.

GENERAL INFORMATION
AIR CONDITIONING SYSTEM PRECAUTIONS
General
The air conditioning system contains fluids and
components which could be potentially hazardous to
the service engineer or the environment if not
serviced and handled correctly. The following
guidelines are intended to alert the service engineer
to potential sources of danger and emphasise the
importance of ensuring the integrity of the Air
Conditioning operating conditions and components
fitted to the vehicle.
Where necessary, additional specific precautions
are detailed in the relevant sections of this Manual
which should be referred to prior to commencing
repair operations.
The refrigerant used in the air conditioning system is
HFC-134a (Hydrofluorocarbon) R134a.
WARNING: The air conditioning system is
charged with a high pressure, potentially
toxic refrigerant. Repairs or servicing
must only be carried out by a trained operator
familiar with both the vehicle system and the
charging and testing equipment.
WARNING: All operations pertaining to the
air conditioning system must be carried
out in a well ventilated area. Always
observe the following precautions:
• R134a is odourless and colourless. Do not
handle or discharge in an enclosed area, or
any area where the vapour and liquid can
come into contact with a naked flame or hot
metal. R134a is not flammable, but it can
cause a highly toxic gas.
WARNING: HFC-134a (R134a) is a
hazardous liquid which if handled
incorrectly can cause serious injury. The
following precautions should be adhered to at all
times when working on an air conditioning
system:
• Suitable protective clothing must be worn
when carrying out service operations on the
air conditioning system.
• Air conditioning connections should be
opened carefully to allow any liquid or
pressure to bleed off slowly.
• Do not allow a refrigerant container to be
heated by direct flame or to be placed near
any heating appliance. A refrigerant container
must not be heated above 50°C.
• Do not leave a refrigerant container without
its cap fitted.
• Do not transport a refrigerant container that
is unrestrained (especially in the luggage
compartment of a car).
• Do not allow fluids, other than R134a or
compressor lubricant, to enter the air
conditioning system; spontaneous
combustion could occur.
• R134a splashed onto exposed skin will cause
immediate freezing of that area.
• Refrigerant cylinders and replenishment
trolleys can become cooled when
discharging, this could cause skin to become
frozen to them if contact is made.
• The refrigerant used in an air conditioning
system must be reclaimed in accordance with
the recommendations stipulated by a
Refrigerant Recovery, Recycling &
Recharging Station.
• Do not smoke or weld in areas where R134a
is in use.
• Inhalation of concentrations of vapour can
cause dizziness, disorientation,
incoordination, narcosis, nausea or vomiting.
• Refrigerant R134a from domestic and
commercial sources must not be used in
motor vehicle air conditioning systems.
AIR CONDITIONING PRECAUTIONS

GENERAL INFORMATION
Protective Clothing
NOTE: Suitable protective clothing
comprises:
• Wrap round safety glasses or helmet
• Heat proof gloves
• Rubber apron, or waterproof overalls
• Rubber boots.
REMEDIAL ACTIONS
If an accident involving R134a should occur, conduct
the following remedial actions:
• If liquid R134a enters the eye, do not rub it.
Gently run large quantities of eye wash over
affected eye to raise the temperature. If an eye
wash is not available, cool, clean water may be
used to flush the eye. After rinsing, cover the eye
with a clean pad and seek immediate medical
attention.
• If liquid R134a is splashed onto the skin, run
large quantities of water over the affected area to
raise the temperature. Implement the same
action if the skin comes in contact with
discharging cylinders. Wrap the contaminated
body parts in blankets (or similar materials) and
seek immediate medical attention.
• If the debilitating effects of inhalation of R134a
vapour is suspected, seek fresh air. If the
affected person is unconscious, move them away
from the contaminated area to fresh air and apply
artificial respiration and/or oxygen and seek
immediate medical attention.
WARNING: Due to its low evaporating
temperature of -30°C, R134a should be
handled with extreme care.

AIR CONDITIONING PRECAUTIONS
GENERAL INFORMATION
SERVICE PRECAUTIONS
CAUTION: Observe the following
precautions when handling components
used in the air conditioning system:
• Air conditioning units must not be lifted by
their hoses, pipes or capillary lines.
• Hoses and lines must not be subjected to any
twist or stress - the efficiency of the system
will be impaired by kinks or restrictions.
Ensure that hoses are correctly positioned
before tightening couplings, and ensure that
all clips and supports are utilised.
• Flexible hoses should not be postioned close
to the exhaust manifold (less than 100mm)
unless protected by heat shielding.
• The receiver/drier should be the last
component connected to the system to
ensure optimum dehydration and maximum
moisture protection of the system.
• Whenever the refrigerant system is opened,
the receiver/dryer must be renewed
immediately before evacuating and
recharging the system.
• Use alcohol and a clean lint-free cloth to
clean dirty connections.
• Ensure that all new parts fitted are marked for
use with R134a.
• When a major repair has been completed, a
leak test should be conducted; refer to the air
conditioning section of this manual for the
correct procedure.
• Completed assemblies must be checked for
refrigeration lines touching metal panels. Any
direct contact of components and panels may
transmit noise and so must be eliminated.
• The appropriate torque wrench must be used
when tightening refrigerant connections to
the stipulated value. An additional spanner
must be used to hold the union to prevent
twisting of the pipe when tightening
connections.
• Before connecting any hose or pipe, ensure
that refrigerant oil is applied to the seat of the
new ’O’ ring seals, BUT NOT to the threads of
the connection.
• All protective plugs must remain in place to
seal the component until immediately prior to
connection.
• Ensure components are at room temperature
before uncapping, to prevent condensation of
moisture from the air that enters it.
• Components must not remain uncapped for
longer than 15 minutes. In the event of a
delay, the caps must be fitted.
• When disconnecting, immediately cap all air
conditioning pipes to prevent ingress of dirt
and moisture into the system.
• The receiver/dryer contains desiccant which
absorbs moisture. It must be positively
sealed at all times. A receiver/drier that has
been left uncapped must not be used, fit a
new unit.
AIR CONDITIONING PRECAUTIONS
3
GENERAL INFORMATION
Refrigerant oil
Rapid refrigerant discharge
Use an approved refrigerant lubricating oil:
CAUTION: If the air conditioning system is
involved in accident damage and the
system is punctured, the refrigerant will
discharge rapidly. The rapid discharge of
refrigerant will also result in the loss of most of
the oil from the system. The compressor must be
removed and all the remaining oil in the
compressor drained and refilled as instructed in
the air conditioning section of this manual.
ND Oil 8
CAUTION: Do not use any other type of
refrigerant oil.
CAUTION: Refrigerant oil easily absorbs
water and must not be stored for long
periods. Do not pour unused oil back into
the container.
When renewing system components, add the
quantities of refrigerant oil recommended in the Air
Conditioning section of this manual.
Compressor
A new compressor is sealed and pressurised with
Nitrogen gas. When fitting a new compressor, slowly
release the sealing cap; gas pressure should be
heard to vent as the seal is broken.
CAUTION: A new compressor should
always have its sealing cap in place and
must not be removed until immediately
prior to fitting the compressor air conditioning
pipes.

AIR CONDITIONING PRECAUTIONS
GENERAL INFORMATION
PRECAUTIONS FOR REFRIGERANT RECOVERY,
RECYCLING AND RECHARGING
WARNING: Refrigerant must always be
recycled before reuse to ensure that the
purity of the refrigerant is high enough for
safe use in the air conditioning system.
WARNING: Recycling should always be
carried out with equipment which is
design certified by Underwriter Laboratory
Inc. for compliance with SAE-J1991. Other
equipment may not recycle refrigerant to the
required level of purity.
A R134a Refrigerant, Recovery, Recycling and
Recharging Station must not be used with any
other type of refrigerant.
CAUTION: When using an air conditioning
portable Refrigerant, Recovery, Recycling
and Recharging Station the operator must
adhere to the equipment manufacturer’s
instructions.
CAUTION: The system must be evacuated
immediately before recharging
commences. Delay between evacuation
and recharging must not be permitted.
CAUTION: Overcharging the air
conditioning system will cause excessive
head pressure.

FLUIDS
Brake Fluid
CAUTION: No other ’universal’ anti-freeze
should be used with UNIPART Superplus 3
Anti-freeze and Summer Coolant. If Land
Rover Parts RTC5779A antifreeze and Summer
Coolant is not available, use an ethylene glycol
based anti-freeze containing no methanol with
non-phosphate corrosion inhibitors which meet
specifications BS6580 and BS5117 suitable for use
in mixed metal engines. To ensure the protection of
the cooling system against corrosion, these
anti-freezes must be renewed every 24 months (or
every 36 months for Land Rover Parts RTC5779A).
Use only AP New Premium Super DOT 4 brake
fluid or Castrol Girling Universal DOT 4
brake/clutch fluid. DO NOT use any other type of
fluid.
Anti-freeze solutions
The overall anti-freeze concentration should not fall,
by volume, below 50% to ensure that the
anti-corrosion properties of the coolant are
maintained. Anti-freeze concentrations greater than
60% are not recommended as cooling efficiency will
be impaired.
After filling with anti-freeze solution, attach a warning
label to a prominent position on the vehicle stating
the type of anti-freeze contained in the cooling
system to ensure that the correct type is used for
topping-up.
Use Land Rover Parts RTC5779A antifreeze and
Summer Coolant to protect the cooling system.
The recommended quantities of anti-freeze for
different degrees of frost protection are:
The cooling system should be drained, flushed and
refilled with the correct amount of anti-freeze
solution at the intervals given on the Service
Maintenance Check Sheet.

ENGINE - ’K’ SERIES
OPERATION
The K Series engine is built up from aluminium
castings bolted together. These consist of three
major castings; the cylinder head, cylinder block and
a bearing ladder which is line bored to provide the
main bearing bores. Attached to these are three
minor castings; above the cylinder head, the
camshaft carrier and the camshaft cover. Below the
bearing ladder is an oil rail.
The cylinder block is fitted with ’damp’ cylinder
liners, the lower part of the ’damp liner’ is stepped
and is a sliding fit into the cylinder block. The liners
are sealed in the block with a bead of sealant
applied around the stepped portion of the liner. The
seal at the cylinder head is effected by the cylinder
head gasket with the liner top acting as a break
between the combustion chamber and gasket.
Each of the ten cylinder head bolts passes through
the cylinder head, cylinder block and bearing ladder
to screw into the oil rail. This puts the cylinder head,
cylinder block and bearing ladder into compression
with all the tensile loads being carried by the cylinder
head bolts.
The aluminium alloy, thermal expansion pistons
have a semi- floating gudgeon pin which is offset
towards the thrust side and has an interference fit in
the small end of the connecting rod. Pistons and
cylinder liners are supplied in two grades. Big-end
bearing diametric clearance is controlled by three
grades of selective shell bearings.
When the cylinder head bolts are removed;
additional fixings are used to retain the bearing
ladder to the cylinder block and the oil rail to the
bearing ladder.
The cross flow cylinder head is based on a four
valve, central spark plug, combustion chamber with
the inlet ports designed to induce swirl and control
the speed of the induction charge. This serves to
improve combustion and hence fuel economy,
performance and exhaust emissions. The camshafts
are retained by the camshaft carrier, which is line
bored with the cylinder head.
Self adjusting hydraulic tappets are fitted on top of
each valve and are operated directly by the
camshaft. The valve stem oil seals are moulded onto
a metal base which also act as the valve spring seat
on the cylinder head.
Exhaust valves are of the carbon break type. A
machined profile on the valve stem removes any
build up of carbon in the combustion chamber end of
the valve guide thereby preventing valves from
sticking.
The stainless steel cylinder head gasket has
moulded seals around all coolant, breather and oil
apertures and has steel cylinder bore eyelets.
Compression of the gasket is controlled by limiters
at each end of the gasket.
6
DESCRIPTION AND OPERATION
The five bearing, eight balance weight crankshaft
has its end-float controlled by thrust washer halves
at the top of the central main bearing. Bearing
diametric clearance is controlled by three grades of
selective shell bearing. Oil grooves are provided in
the upper halves of main bearings No. 2, 3 and 4 to
supply oil, via drillings in the crankshaft, to the
connecting rod big-end bearings.
ENGINE - ’K’ SERIES
Engine lubrication system
DESCRIPTION AND OPERATION

ENGINE - ’K’ SERIES
Lubrication
ENGINE NUMBER LOCATION
The lubrication system is of the full-flow filtration,
forced fed type. The oil sump is manufactured from
aluminium alloy and is sealed to the bearing ladder
with a bead of liquid sealant applied to the sump
flange.
Oil is drawn, via a strainer and suction pipe (1) in the
sump, into the crankshaft driven oil pump (2) of the
trochoid type which has an integral pressure relief
valve (3), excess oil is diverted into the intake (4) of
the oil pump. Oil is pumped through the full-flow
cartridge type oil filter (5), mounted on an adapter
attached to the oil pump housing. The low oil
pressure sensor (6) is also screwed into the adapter
and registers the oil pressure in the main oil gallery
on the outflow side of the filter.
The main oil gallery (7) is fed through the oil rail
below the main bearing ladder in which drillings
direct the oil to the main bearings. Cross drillings in
the crankshaft from No. 2 and 4 main bearings carry
the oil to the big-end bearings. A passage in the oil
pump housing connects to a drilling (8) in the
cylinder block to oilways (9) in the cylinder head.
Oil is fed through the cylinder head to twin full length
oilways (10) in the camshaft carrier to supply oil to
each hydraulic tappet and camshaft bearing.
Crankcase ventilation
A positive crankcase ventilation system is used to
vent blow-by gas from the crankcase to the air
intake system.
Crankcase gas is drawn through a gauze oil
separator in the camshaft cover and passes via
hoses into the throttle housing.

ENGINE - ’L’ SERIES
DESCRIPTION
The ’ L’ Series 2.0 litre engine is a 4 cylinder, in-line,
direct diesel engine having 2 valves per cylinder
operated by a single overhead camshaft.
A cast iron cylinder block incorporates direct bored
cylinders, each pair of cylinders being strategicly
positioned in the cylinder block to reduce engine
length and give good structural rigidity.
An alloy camshaft carrier is bolted directly to the
alloy cylinder head, the camshaft bearing journals
are line bored between the two components. The
camshaft operates the valves via hydraulic tappets,
the camshaft gear, which incorporates a tortional
damper, is driven by an internally toothed drive belt
by a gear on the front of the crankshaft. Belt tension
is achieved by means of a semi-automatic tensioner
and an idler pulley is also fitted. A gear on the rear
end of the camshaft drives the fuel injection pump
belt.
A single spring is fitted to each valve, the valve stem
oil seals are moulded onto a metal base which also
forms the valve spring seat on the cylinder head.
The valve stems run in guides pressed into the
cylinder head.
The crankshaft runs in 5 main bearings, grooved
bearing shells are fitted in the cylinder block with
plain bearing shells in each main bearing cap.
Positive location of each main bearing cap is by
means of hollow dowels. Crankshaft end-float is
controlled by single size thrust washers, located
each side of the centre - (Number 3) main bearing in
the cylinder block. The crankshaft front oil seal is
located in the oil pump body whilst the rear oil seal is
integral with a housing bolted to the rear of the
cylinder block. Additional oil sealing is provided by
RTV sealant injected into grooves and along the
joint lines of the front main - (Number 1) bearing cap
and the crankshaft rear oil seal.
A rotor type oil pump is driven from the front of the
crankshaft, the pump is sealed to the cylinder block
with a gasket.
The cast alloy sump is bolted to the cylinder block
and rear main bearing cap and is sealed to the block
with a rubber gasket which incorporates location
lugs for the block and sump. Compression limiters in
the bolt holes prevent distortion of the gasket.
The aluminium alloy, graphite coated pistons are
fitted with two compression and an oil control ring,
the top ring is located in a steel insert which helps to
provide a minimal reaction to compression forces.
The piston crowns are domed in the centre, the
combustion chamber being formed in a bowl around
the dome. Fully floating gudgeon pins retain the
pistons to the connecting rods, the pins are offset
towards the thrust side of the pistons and are
secured in the pistons by circlips.
Oil squirt jets, located in the cylinder block provide
additional piston cooling and gudgeon pin
lubrication. Plain big-end bearing shells without
location tags are fitted, with the connecting rod
bearing caps being retained by flange headed bolts
to the connecting rods. The big-end has a ’Fracture
Split’ joint between the connecting rod and bearing
cap. The connecting rod to bearing cap has no
identification marks, therefore, to prevent incorrect
fitment of the bearing cap to connecting rod, the
bolts are off-set by 1mm.
DESCRIPTION AND OPERATION

ENGINE - ’L’ SERIES
Lubrication
Oil is drawn through a gauze strainer (1) and
through a passage in the cylinder block to the oil
pump (2). Pressurised oil flows via the full flow filter
(3) to the main oil gallery in the cylinder block.
Drillings from the main oil gallery direct oil to the
crankshaft main bearings (4) and cross drillings in
the crankshaft direct oil to the big-end bearings (5).
Additional drillings in the cylinder block supply oil at
reduced pressure to the oil squirt jets (7) for piston
cooling and gudgeon pin lubrication and via a
restrictor (8) in the top of the cylinder block to the
rear of the cylinder head. A full length drilling in the
cylinder head directs oil to the camshaft journals (9)
and tappets (10).
6
DESCRIPTION AND OPERATION
An oil pressure relief valve (11) is located in the oil
pump body which also carries the oil filter adapter
and the return union for the externally mounted oil
cooler.
A thermostatic valve (12), comprising a valve, spring
and diverter plug is located in the oil pump body.
The oil flow union to the oil cooler is screwed into the
end of the diverter plug. The valve is closed during
engine warm-up thereby preventing oil flow to the oil
cooler. As soon as the oil reaches a pre-determined
temperature, the valve opens and allows oil to flow
to the cooler.
ENGINE - ’L’ SERIES
Crankcase ventilation
A positive crankcase ventilation system is used to
vent crankcase gases to the air induction system.
The gases are drawn from the camshaft cover,
through a depression limiting valve and into the
turbocharger intake.
As engine speed increases, the depression limiting
valve progressively closes thereby limiting the
depression in the crankcase.
Engine number location
The engine number will be found on the side of the
cylinder block adjacent to Number 2 cylinder.

EMISSION CONTROL
TYPES OF EMISSION
Vehicles powered by internal combustion engines
produce by-products in the form of emissions which
are harmful to the environment. The main
by-products are:
• Carbon Monoxide (CO) - a colourless,
odourless gas which is formed when fuel is burnt
in the combustion process and is a result of
incomplete combustion.
WARNING: Carbon monoxide is
dangerous to inhale and is potentially
lethal. Concentrations are particularly high
when a vehicle is running at idle speed; it is
therefore important to use exhaust extraction
equipment when running a vehicle in a
workshop or other confined space.
Spark-ignition engines are particularly
responsible for carbon monoxide emissions; an
air/fuel mixture which is rich in fuel produces an
excessive concentration of CO. It is important
that vehicles with petrol engines are correctly
tuned and maintained to provide the optimum
air/fuel mixture and so ensure that carbon
monoxide emissions are minimised.
Diesel engines are lean running, so tend to
produce less CO emissions than equivalent
petrol engines. However, if there is not enough
excess air in the combustion chamber,
increased emissions of carbon monoxide will
result, as well as higher concentrations of soot
and hydrocarbons (HC).
• Hydrocarbons (HC) - present in exhaust gases
and like carbon monoxide, are a result of unburnt
fuel during combustion. HC concentrations
increase as the air/fuel mixture becomes rich and
also increase if a misfire occurs.
• Carbon Dioxide (CO2) - is a by-product of
complete combustion and contributes to the
"greenhouse effect". Carbon Dioxide is produced
even under perfect combustion conditions.
• Oxides of Nitrogen (NOx) - includes Nitric Oxide
(NO) and Nitrogen Dioxide (NO2) and is
produced in exhaust gases. Lean mixtures
produce more oxides of nitrogen than rich
mixtures as the combustion temperature is
increased. Oxides of Nitrogen together with
Sulphur Dioxide SO2 contribute to the formation
of "acid rain".
EMISSION CONTROL SYSTEMS
In order to minimise emissions of harmful
by-products, emission control systems are fitted to
Freelander which are designed to keep the
emissions within legal limits pertaining at the time of
manufacture.
Despite the utilisation of specialised emission control
equipment, it is still essential that the engine is
correctly maintained and is in good mechanical
order so that it operates at its optimal condition. In
particular, ignition timing has an effect on the
production of HC and NO2 emissions, with the
emissions rising as the ignition timing is advanced.
CAUTION: In many countries it is against
the law for a vehicle owner or an
unauthorised repair shop to modify or
tamper with emission control equipment. In this
event the vehicle owner and/or the repairer may
be liable for prosecution. Three main types of
control system are used to reduce harmful
emissions released into the atmosphere from the
vehicle. These are:
1. Crankcase emission control - also known as
blow-by gas emissions from the engine
crankcase.
2. Exhaust emission control - to limit the
undesirable by-products of combustion.
3. Fuel vapour evaporative loss control - to
restrict the emission of fuel through
evaporation from the fuel system.
DESCRIPTION AND OPERATION
1
EMISSION CONTROL
Crankcase emission control system - ’K’ series
The concentration of hydrocarbons in the crankcase
of an engine is much greater than that in the
vehicle’s exhaust system. In order to reduce the
emission of these hydrocarbons, crankcase
emission-control systems are a standard legal
requirement.
The crankcase emission control system is designed
to allow the engine crankcase to breathe, but
prevent blow-by gas containing HC and CO
pollutants from escaping to the atmosphere.
The K-series engine uses a positive crankcase
ventilation system to vent the gases from the
crankcase to the intake system. Gases from the
crankcase are drawn into throttle housing to be burnt
in the combustion chambers with the fuel mixture.
The system provides effective emission control while
the engine is running under all circumstances.
The camshaft cover has two apertures to faciltate
engine breathing. The larger orifice is connected
upstream of the throttle disc in the throttle housing
via a plastic pipe with rubber hose elbows which
connect to ports at the camshaft cover and throttle
housing. The smaller orifice is connected to a port
further downstream in the air intake line via a short
rubber hose to the inlet manifold housing. A gauze
oil separator is included in the camshaft cover to
prevent oil mist being drawn into the engine.
2
DESCRIPTION AND OPERATION
When the engine is running at idle speed, the
throttle disc is closed and manifold depression in the
inlet manifold side of the disc causes crankcase
gases to be drawn through the oil separator and
small orifice in the camshaft cover. Clean air enters
the crankcase through the large orifice in the
camshaft cover, which then mixes with the
crankcase gas before it is drawn into the engine via
the inlet manifold to be burnt in the combustion
chambers with the fuel mixture. This ensures
unburnt and partially burnt fuel is returned for
combustion and so prevents harmful crankcase
gases escaping to the atmosphere.
When the engine is running with the throttle disc
wide open, pressure at either side of the disc is
equalized and both pipes are subjected to the same
manifold depression. In this condition, most of the
crankcase gases are drawn through the large orifice
in the camshaft cover to be mixed with clean air at
the throttle housing before being drawn into the
engine for combustion.
In between the fully open and fully closed conditions
of the throttle disc, the difference in manifold
depression at either side of the throttle housing
determines the direction of flow of ventilation through
the crankcase.
REVISED: 11/99
EMISSION CONTROL
Crankcase emission control system - ’L’Series
Exhaust emission control - ’K’ Series
A positive crankcase ventilation system is used to
vent crankcase gases to the air induction system.
Gases from the crankcase are drawn into the inlet
manifold to be burnt in the combustion chambers
with the fresh air/fuel mixture. The system provides
effective emission control while the engine is running
under all circumstances.
The engine management system provides
accurately metered quantities of fuel to the
combustion chambers to ensure the most efficient
air to fuel ratio under all conditions of operation. A
further improvement to combustion is made by
measuring the oxygen content of the exhaust gases
to enable the quantity of fuel injected to be varied,
maintaining the optimal ratio necessary for efficient
gas conversion by the catalytic converter.
Crankcase gases are drawn from the camshaft
cover into the turbocharger intake via a depression
limiting valve (crankcase pressure limiting valve).
The valve closes progressively as engine speed
increases, so limiting the maximum depression in
the crankcase.
NOTE: Injection timing is extremely
important with regards the effects on
emissions. The 2.0 L-series engine
injection timing is electronically controlled
(Refer to the Engine Management - EDC section
of this manual for further information).
The correct operation of the catalytic converter is
dependent upon closed-loop control of the oxygen
concentration in the exhaust gas entering the
converter. The quantity of oxygen in the exhaust gas
is determined by a heated oxygen sensor situated in
the exhaust front pipe. The heated oxygen sensor
provides the Engine Control Module (ECM) with a
signal proportional to the oxygen content. The ECM
can then determine whether any adjustment is
required to the amount of fuel being injected to
achieve the correct exhaust gas content, and
implement the required changes.
NOTE: The Freelander 2.0 L-series engine
incorporates an intercooled turbo-charger.
Cooling the intake air increases the
density of the oxygen mass per unit volume that
is available for combustion, and so improves the
engine combustion performance. In addition, the
lower combustion temperature helps to inhibit
the formation of oxides of Nitrogen (NOx).
CAUTION: The depression limiting valve
taking crankcase fumes to the intake of
the turbo-charger must be fitted in the
correct orientation.

EMISSION CONTROL
Catalytic Converter (CAT) ’K’ Series
The CAT is mounted between the front pipe and the
intermediate pipe assemblies. A flange is welded to
each end with three captive bolts in each flange. The
CAT is connected to the mating flanges of the front
and centre silencer assemblies and secured with
three nuts on each flange. A metal gasket seals
each flanged joint.
The CAT is fabricated from stainless steel and
welded fully at all it’s joints. The catalyst element
comprises of a ceramic element which is formed into
a honeycomb of small squares. The ceramic
element is coated with a special surface treatment
called ’washcoat’. The washcoat increases the
surface area of the catalyst element by
approximately 7000 times. A coating is applied to
the washcoat which contains the precious metals
Platinum, Rhodium and Palladium.
The metallic coating of platinum and palladium
oxidize the carbon monoxide and hydrocarbons and
convert them into water (H2O) and carbon dioxide
(CO2). The coating of rhodium removes the oxygen
from nitrogen oxide and converts it into nitrogen.
The efficient operation of the CAT is highly
dependant on the content of oxygen in the exhaust
gases which is controlled by the ECM in response to
signals from the heated oxygen sensor.
NOTE: Refer to the Engine Management MEMS section for a desciption of the
heated oxygen sensor.
CAUTION: The catalytic converter will be
irreparably damaged if leaded fuel is used.
Leaks in the exhaust system will also
damage the catalyst by drawing oxygen into the
exhaust system which causes the catalyst to
overheat.
Engine misfires can cause overheating of the
catalyst which may lead to overheating and
melting the element and partially blocking the
exhaust system.
Only use unleaded fuel, the filler neck is
designed to accommodate only unleaded fuel
pump nozzles.

DESCRIPTION AND OPERATION
Exhaust Gas Recirculation (EGR) - ’L’ series
models
Freelander vehicles fitted with the 2.0 L-series
engine utilise an EGR System to reduce NOx
emissions. This is achieved by recirculating exhaust
gases back into the combustion process which
reduces combustion temperature by delaying the
fuel burning rate.
Recirculating too much exhaust gas can result in
higher emissions of soot, HC and CO due to
insufficient air. Therefore, the precise quantity of
recirculated gas is controlled by the Engine
Management System - EDC to ensure the optimal
operating conditions are maintained.
The exhaust gases pass through an EGR cooler
before they are mixed with intake air. The EGR
cooler is mounted on the side of the EGR valve
which is located on the exhaust manifold. The EGR
cooler receives coolant from the cylinder block which
then circulates through the cooler to cool the
exhaust gases. The cooled gases are drawn from
the cooler and mixed in the inlet manifold with the
intake air from the intercooler.
NOTE: Refer to the Engine Management
System - EDC section for additional
descriptions and operations of
components and related systems affecting the
limitation of emissions (such as the intake air
system and fuel injection control).
See ENGINE MANAGEMENT SYSTEM - EDC,
Information.
EMISSION CONTROL
EGR modulator valve
Catalytic Converter (CAT) ’L’ Series
Hydrocarbon and Carbon Monoxide emissions are
reduced through the use of a catalytic converter in
the exhaust system where pollutants are burned
using the oxygen contained in the exhaust gas.
The CAT is mounted between the downpipe and the
intermediate pipe. A flange is welded to each end
with three captive bolts in each flange. The CAT is
connected to the mating flanges of the downpipe
and intermediate pipe and secured with three nuts
on each flange. A metal gasket seals each flanged
joint.
The EGR modulator valve is vacuum operated
through a solenoid valve, mounted on the bulkhead.
When the Engine Control Module (ECM) determines
that exhaust gas recirculation should take place, the
solenoid valve is modulated and vacuum, supplied
by the brake servo vacuum pump, opens the EGR
valve. Exhaust gases are then fed through the EGR
cooler into the inlet manifold. When EGR is not
required the ECM switches the control solenoid to
close the EGR valve.
The EGR solenoid valve operates at a frequency of
300 Hz. The signal pressure to the EGR valve from
the EGR modulator valve is controlled between the
vacuum supplied from the vacuum pump and
atmospheric pressure supplied via an air cleaner
attached to the EGR modulator valve.
The CAT is fabricated from stainless steel and
welded fully at all it’s joints. The catalyst element
comprises a ceramic matrix formed into a
honeycomb of small squares. The matrix is coated
with a special surface treatment called ’washcoat’.
The washcoat increases the surface area of the
catalyst element by approximately 7000 times. A
coating is applied to the washcoat which contains
the precious metal Platinum.
The metallic coating of platinum oxidizes the carbon
monoxide and hydrocarbons and converts them into
water (H2O) and carbon dioxide (CO2).
If the EGR modulator valve fails in the stuck open
position, a decrease in engine performance, and an
increase in visible smoke emissions will be noticed.
The effects of a stuck closed modulator valve may
not be noticed by the driver.
A MAF sensor is mounted in the air cleaner outlet
pipe to sense the volume of air entering the engine.
An increase in EGR will cause a corresponding
decrease in clean intake air flow, the MAF sensor
detects this difference so that the ECM can monitor
and control the volume of exhaust gases being
recirculated.

vent lines and a purge control solenoid valve.
Fuel vapour generated from within the fuel tank as
the fuel heats up is stored in the tank until the
pressure exceeds the operating pressure of the
two-way valve. When the two way valve opens, the
fuel vapour passes along the vent line from the fuel
tank (via the fuel tank vapour separator) to the inlet
port of the carbon canister.

As fuel vapour cools, it condenses and is allowed to
flow back into the fuel tank from the vent line by way
of the two-way valve. A fuel vapour separator is
fitted next to the fuel filler neck. This separator
allows condensing fuel in the fuel tank to be returned
to the tank before it reaches the vent line.
EMISSION CONTROL
Evaporative emission canister
The evaporative emission canister contains charcoal
which absorbs and stores fuel vapour from the fuel
tank while the engine is not running. When the
canister is not being purged, the fuel vapour remains
in the canister and clean air exits the canister via the
air inlet port.

8. Fuel trap to ECM pipe
9. Inlet manifold to fuel trap pipe
When the engine is running, the ECM decides when
conditions are correct for vapour to be purged from
the canister, and opens the canister purge valve.
This connects a manifold vacuum line to the canister
and fuel vapour is drawn from the canister’s
charcoal element to be burned in the engine. Clean
air is drawn into the canister through the air inlet port
to fill the displaced volume of vapour.
Evaporative emission canister purge valve
The operation of the evaporative emission canister
purge valve is controlled by the ECM. The purge
valve is located on top of the carbon canister. The
valve remains closed below preset coolant and
engine speed values to protect engine tune and
catalytic converter performance. If the charcoal
canister was purged during cold running or at idling
speed, the additional enrichment in fuel mixture
would delay the catalytic converter light off time and
cause erratic idle. When the purge valve is opened,
fuel vapour from the charcoal canister is drawn into
the throttle housing for combustion.

Fuel Filler Cap
The fuel tank filler cap incorporates a pressure valve
which allows excess pressure to escape (blow-off) at
between 10 - 10.8 kPa, (1.50 - 1.57 psi).
Two way Valve
A two way valve is included in the vent line which
allows tank pressure to build to 1.80 - 5.03 kPa,
(0.26 - 0.73 psi). Above this pressure, vapour is
allowed to pass along the vent line to the carbon
canister. Vapour is allowed to flow back into the fuel
tank as the fuel cools by way of a non return valve
within the body of the two way valve.

DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - MEMS
MODULAR ENGINE MANAGEMENT SYSTEM
OPERATION
The Modular Engine Management System (MEMS)
is a combined engine management system using a
single Engine Control Module to control the
multipoint fuel injection, idle speed control and
ignition systems.
Electronic Control Module (ECM)
The ECM processes all inputs and outputs related to
the operation of the fuel injection and ignition
systems. The ECM is located on a mounting plate
behind the battery in the engine compartment. The
ECM comprises an aluminium cast body with a
pressed alloy sealed lid. A socket is positioned on
it’s side face and receives a multiplug from the
engine wiring harness. The socket contains 36 pins,
although only the pins corresponding to those in the
multiplug are used.
The multiplug is connected to the engine wiring
harness to each individual sensor. The multiplug fits
into the corresponding socket on the side face of the
ECM and is locked in position with a plastic clip. A
rubber seal within the body of the multiplug prevents
the ingress of moisture. The ECM harness multiplug
incorporates plated pins to minimise oxidation and
give improved reliability.
The ECM monitors the conditions required for
optimum combustion of fuel in the cylinder through
sensors located at strategic points around the
engine. From these sensor inputs, the engine control
module can adjust the fuel quantity and timing of the
fuel being delivered to the cylinders.
The main features are as follows:
• A single ECM controls the fuel injection system
and the ignition system. The ECM incorporates
short circuit protection and can store intermittent
faults on certain inputs. TestBook can interrogate
the ECM for these stored faults.
• In conjunction with the Throttle Position (TP)
sensor, the ECM uses the speed/density method
of air flow measurement to calculate fuel
delivery. This method measures the crankshaft
position/speed, inlet air temperature and inlet
manifold pressure and assumes that the engine
is a calibrated vacuum pump, with its
characteristics stored in the ECM, it can then
determine the correct amount of fuel to be
injected.
• The ECM contains an integral Manifold Absolute
Pressure (MAP) sensor. The MAP sensor reads
manifold pressure via a hose connected to the
inlet manifold. The manifold pressure is
monitored by the ECM, which in turn adjusts the
injector pulse width to maintain the correct fuel
delivery relative to the air flow ratio. This system
removes the need for a fuel pressure regulator
and fuel return line on the fuel rail. The device
which normally functions as a fuel pressure
regulator on other ’K’ series applications is now
used as an accumulator to damp fuel pump
pulses in the fuel rail.
• A separate diagnostic socket, located behind the
centre console in the passenger footwell, allows
engine diagnostics and tuning to be carried out
using TestBook, without disconnecting the ECM
harness multiplug.
• The ECM controls the operation of the radiator
cooling and air conditioning (if fitted) fans based
on signals received from the engine coolant
temperature sensor and air conditioning system.
If a high engine temperature is detected, the
ECM will prevent the air conditioning system
from operating.
• If certain system inputs fail, the ECM implements
a back-up facility to enable the system to
continue functioning, although at a reduced level
of performance.
DESCRIPTION AND OPERATION
3
ENGINE MANAGEMENT SYSTEM - MEMS
• The ECM also operates the engine
immobilisation circuits. When the ignition is
switched to position II, a coded signal is sent to
the ECM from the Central Control Unit (CCU). If
the coded signal does not match the signal
programmed into the ECM, the ECM disables the
fuel injection function.
NOTE: If an incorrect code is received, but
the key is turned very quickly from off to
crank, the engine may start for a very
short period, then stop. This is quite normal.
• On vehicles fitted with ABS, the ECM provides
signal information to the ABS ECU for hill
descent control.
The ECM is an adaptive unit which over a period of
time learns the load and wear characteristics of the
engine it controls. The ECM remembers and
updates two main engine requirements when the
engine is running at normal operating temperature:
• The position of the idle air control (IAC) valve
required to achieve a specified idle speed. This is
then used as a reference for IAC valve
movement to achieve idle speed under all load
conditions.
• The fuelling change or offset required to achieve
the correct oxygen sensor signal. This allows the
system to provide the correct fuelling without
having to apply excessive adjustments to the
fuelling which can adversely affect the emissions
and driveability.
NOTE: After fitting a different ECM,
TestBook will be required to reprogramme
the ECM with the code from the CCU and
to perform the throttle initialisation procedure.
WARNING: When washing under bonnet,
never direct water onto the ECM, as water
ingress may occur, resulting in damage to
electrical components inside.

ENGINE MANAGEMENT SYSTEM - MEMS
IGNITION SYSTEM
The ECM determines the optimum ignition timing
based on the signals it receives from the following
sensors:
1. Crankshaft position sensor - Engine speed and
crankshaft position
2. Manifold absolute pressure sensor - Engine
load
3. Engine coolant temperature sensor - Engine
temperature
4. Throttle position sensor - Throttle pedal
released
5. Intake Air Temperature sensor - intake air
temperature
The engine management system uses no centrifugal
or vacuum advance, the timing being controlled by
the ECM.
Spark distribution is achieved by means of a rotor
arm and distributor mounted at the No.4 cylinder end
of the inlet camshaft.
The CKP sensor is an inductive sensor containing a
coil and a permanent magnet which provides a
magnetic field. The sensor is situated such that an
air gap exists between it and the flywheel. Air gap
distance is critical for correct operation.
The flywheel incorporates a reluctor ring which
consists of 32 poles spaced at 10° intervals, with 4
missing poles at 0°, 50°, 180° and 240°. The missing
poles tell the ECM when to operate the injectors.
When the flywheel rotates and a pole passes the
CKP sensor, it disturbs the magnetic field inducing a
voltage pulse in the coil. This pulse is transmitted to
the ECM.
By calculating the number of pulses that occur within
a given time, the ECM can determine the engine
speed. The output from the CKP sensor, when used
in conjunction with that from the Manifold Absolute
Pressure (MAP) sensor, provides idle stabilisation
and reference for injection timing.
If the CKP sensor fails, the engine will stop and
cannot be restarted.
Basic Ignition Timing
Manifold Absolute Pressure (MAP) Sensor
Crankshaft Position (CKP) Sensor
The MAP sensor is located within the ECM and
detects manifold pressure via a hose connected to
the inlet manifold. A fuel trap is fitted in the hose
from the inlet manifold to prevent fuel and oil
residues from entering the MAP sensor.
The sensor converts pressure variations into
graduated electrical signals which can be read by
the ECM. Increases and decreases in the manifold
pressure provide the ECM with an accurate
representation of the load being placed on the
engine, allowing the ECM to adjust the quantity of
fuel being injected and the ignition timing to achieve
optimum fuelling of the engine.
If the MAP sensor fails, the ECM enters a default
mode (called ’Pressure Back-up’), using a substitute
value determined from engine speed and throttle
position.
The speed and position of the engine is detected by
the CKP sensor which is bolted to, and projects
through, the engine adapter plate adjacent to the
flywheel.

DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - MEMS
Ignition Timing Compensation
Idle Speed Control
Engine Coolant Temperature (ECT) Sensor
With the throttle pedal released and the engine at
idle, the ECM uses the fast response of ignition
timing to maintain idle stabilisation.
The ECT sensor is located in the coolant outlet
elbow which is attached at the front of the cylinder
head. The sensor is screwed into a threaded port
and measures coolant temperature as it leaves the
engine via the top hose to the radiator.
When loads are placed on, or removed from the
engine the ECM senses the change in engine speed
and in conjunction with adjusting the Idle Air Control
(IAC) valve, advances or retards the ignition timing
to maintain a specified idle speed. When load is
removed from the engine, the IAC returns to its
original position and the ignition timing returns to the
idle setting.
NOTE: Due to the sensitivity of this
system the ignition timing will be
constantly changing at idle speed.
Ignition Components
Ignition Coil
The ECT sensor is a ’thermistor’ (a temperature
dependent resistor) with a Negative Temperature
Coefficient, i.e. its resistance reduces as
temperature increases. The ECM receives a signal
from the ECT sensor which is directly proportional to
engine coolant temperature. The ECM uses the
information to provide optimum driveability and
emissions by advancing or retarding the ignition
timing.
If the ECT sensor fails, the ECM enters a default
mode using a substitute value of 60.2°C, and
activates the cooling fan(s) whilst the engine is
running.
The coil for the programmed ignition system is
mounted on the cylinder head, adjacent to the
distributor cap. The coil is connected to the
distributor cap centre connection with a short high
tension (ht) lead. The use of a ’dry’ ignition coil
allows the coil to be mounted on the engine. A two
pin plug connects the coil to the engine wiring
harness.
The coil has a lower primary winding resistance
(0.71 to 0.81 ohms at 20°C) than a coil in a
conventional ignition system. This allows the full ht
output to be reached faster and so makes the coil
operation more consistent throughout the engine
speed range. To prevent excessive current draw,
and to give a constant energy spark, the ECM
constantly varies the ignition coil charge period
(dwell period/angle) with engine speed. The faster
the engine speed, the larger the dwell period/angle.
If the coil fails, ht output will lost and the engine will
stop.
DESCRIPTION AND OPERATION

ENGINE MANAGEMENT SYSTEM - MEMS
Distributor Cap and Rotor Arm
FUEL SYSTEM
The distributor cap is located on the left hand end of
the cylinder head. A rotor arm is driven directly off
the inlet camshaft. The cap is retained on its
mounting with two captive bolts.
Intake Air Temperature (IAT) Sensor
The IAT sensor is located in the side of the inlet tract
to the the No. 4 cylinder and can be identified by a
green electrical connection.
The cap has five external connections; four for the ht
leads to the spark plugs and one to receive the ht
lead from the ignition coil. A spring loaded carbon
brush is located centrally inside the cap and
connects with the rotor arm. The rotor arm is
secured by a retaining screw to a ’D’ shaped stub
shaft, which is press fitted into a vibration absorbing
bush in the camshaft. The rotor arm is protected
from oil contamination by an anti-flash shield which
incorporates an oil drain.
This sensor is of the negative temperature
coefficient (NTC) type, designed to reduce its
resistance with increasing temperature. The ECM
receives a signal proportional to the temperature of
the intake air. When used in conjunction with the
signal from the MAP sensor, the ECM can calculate
the volume of oxygen in the air and adjust the
quantity of fuel being injected to achieve optimum
fuelling of the engine. The IAT sensor signal is also
used to adjust ignition timing.
If the IAT sensor fails, the ECM enters a default
mode using a substitute value of 35.5°C.

Four equally spaced contacts inside the distributor
cap provide the electrical path from the coil to the

rotor arm via the carbon brush and finally to each of
the four ht leads in turn as the rotor arm passes
each internal contact.

DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - MEMS
Injectors
The four fuel injectors are fitted between the
pressurised fuel rail and the inlet manifold. Each
injector comprises a solenoid operated needle valve
and a specially designed nozzle to ensure good fuel
atomisation.
The injectors are controlled in grouped mode with 2
& 3 being grouped and 1 & 4 being grouped, with
the injectors in each group being operated
alternately.
The ECM determines when to operate the injectors
based on the signal it receives from the CKP sensor.
The ECM provides an earth signal for the period the
injectors are required to be open, the injector
solenoids are energised and fuel is sprayed into the
inlet manifold onto the back of the inlet valves. The
ECM carefully meters the amount of fuel injected by
adjusting the injector opening period (pulse width).
During cranking, when the engine speed is below
approximately 400 rev/min, the ECM increases the
injector pulse width to aid starting. The amount of
increase depends upon engine coolant temperature.
To prevent flooding during cranking, the ECM
periodically inhibits the operation of the injectors.
Throttle Housing and Inlet Manifold
The plastic throttle housing is located between the
plastic inlet manifold and air intake hose and is
sealed to the manifold by an ’O’ ring. The throttle
housing incorporates a throttle disk which is
connected to the throttle pedal via the throttle lever
and a cable. Mounted on the throttle housing is the
throttle position sensor. The throttle housing also
provides the attachment point for the throttle cable
mounting bracket. The throttle cable is connected to
the throttle disk via a semi circular lever. An Idle Air
Control (IAC) valve is mounted on the inlet manifold.

The throttle disk position is set during manufacture
and is not adjustable. A throttle position screw is
fitted to allow the throttle disk to close at its optimum
position.
There are two breather hoses from the camshaft
cover; one hose is fitted to the inlet manifold and the
other is fitted to the throttle housing. Both pipes are
connected to a gauze filter in the camshaft cover to
prevent engine oil being drawn into the engine by
the substantially greater manifold depression.
The throttle position (TP) sensor is attached to the
throttle disk pivot shaft and secured to the throttle
housing with two Torx head screws.
The IAC valve is attached to the inlet manifold with
four Torx head screws. The valve is connected to
the inlet manifold via a port and sealed with an
O-ring. A rubber hose connects the valve to the inlet
side of the throttle housing.
DESCRIPTION AND OPERATION
11
ENGINE MANAGEMENT SYSTEM - MEMS
Throttle Position (TP) Sensor
The TP sensor is located on the throttle housing and
secured with two Torx head screws. The sensor is
directly attached to the throttle disk spindle and its
movement is proportional to throttle movement.
The TP sensor is a rotary potentiometer. The ECM
supplies the sensor with a 5 volt supply and an earth
path. The sensor returns a signal proportional to
throttle disk position. Closed throttle is detected by
the TP sensor which prompts the ECM to initiate idle
speed control via the IAC valve.
Throttle disk movement causes voltage across the
potentiometer to vary. The ECM calculates the rate
of change of the voltage signal in positive
(acceleration) or negative (deceleration) directions.
From this the ECM can determine the required
engine speed, rate of acceleration or, rate of
deceleration and apply acceleration enrichment,
deceleration fuel metering or over-run fuel cut-off.
12
DESCRIPTION AND OPERATION
If the TP sensor fails, the ECM enters a default
mode and, using a substitute value, assumes that
the throttle disk is fully closed.
NOTE: The position of the throttle disk is
preset during manufacture and the throttle
position setting screw MUST NOT be
adjusted unless directed by TestBook. The TP
sensor is not adjustable and the ECM is
designed to learn the throttle closed position
and adapt to any changes which may occur
throughout the life of the engine. If the
relationship between the TP sensor and the
throttle disc is changed for any reason (renewal
of TP sensor etc.), the TestBook throttle
initialisation procedure MUST be carried out.
ENGINE MANAGEMENT SYSTEM - MEMS
Idle Air Control (IAC) Valve
The IAC valve is located on the inlet manifold and is
secured with four Torx head screws. The IAC valve
comprises a stepper motor and a pintle valve
enclosed in a plastic housing. The IAC valve is
directly controlled by the ECM.
The IAC valve opens or closes the pintle valve which
is situated in an air passage in the throttle housing,
allowing air to bypass the throttle disk and flow
straight into the inlet manifold. By changing the
amount the IAC valve is open, the ECM can control
engine idle speed and cold start air flow
requirements by adjusting the flow of air through the
passage. The position of the IAC valve can be
checked using Testbook. When adjusting to the
displayed limits, it is important that no electrical or
mechanical loads are applied (cooling fan, A/C etc.).
During cold starting, the ECM indexes the IAC valve
to open a calculated amount to provide a level of
fast idle, dependent on engine coolant temperature.
As the engine warms, the fast idle is decreased by
gradually closing the IAC valve pintle until normal
operating temperature is reached.
The position of the IAC valve can be checked using
TestBook and should be within the range of 20 to 40
steps when the engine is running at normal
operating temperature. If it is identified as being
outside this range it can be adjusted to within range
using TestBook. This ensures that the IAC valve is
at the optimum position within its range for providing
further movement to compensate for changes in
engine load or temperature in accordance with
signals from the ECM.
If the IAC valve fails, the engine may continue to idle
depending on the position of the stepper motor prior
to failure.
DESCRIPTION AND OPERATION
13
ENGINE MANAGEMENT SYSTEM - MEMS
Relay Module
Fuel Pump
The relay module is located in the engine
compartment behind the ECM. The relay module
contains the following relays:
• Main relay - energised by the ECM when the
ignition is switched on and supplies power to the
ECM. The ECM controls the main relay and will
maintain the main relay in an energised state for
a predetermined period after the ignition is
switched off. This allows time for the ECM to
’power down’ and prepare itself for the next
engine start.
The fuel pump is installed in a unit located inside the
top face of the fuel tank. It is accessible by raising
the rear passenger seat and removing a sealed
cover plate. The electric fuel pump is located inside
the fuel tank and is energised by the ECM via the
fuel pump relay in the relay module via the inertia
fuel shut-off (IFS) switch.
• Fuel pump relay - energised by the ECM for a
short period when the ignition is switched on,
during cranking and while the engine is running.
• Starter relay - energised by the cranking signal
from the ignition switch via the CCU and supplies
power to the starter motor solenoid.
The fuel pump delivers more fuel than the maximum
load requirement for the engine, pressure is
therefore maintained in the fuel system under all
conditions. A fuel pressure regulator is located in the
same housing as the fuel pump.
Fuel Pressure Regulator
The fuel pressure regulator is a mechanical device
located in the tank unit with the fuel pump.
• Heated oxygen sensor relay - energised by the
ECM and supplies current to the heating element
of the heated oxygen sensor.
The regulator is connected to the fuel delivery pipe
from the pump and ensures that constant fuel
pressure in the fuel line is maintained. When
pressure from the pump exceeds the regulator
setting, the pressure overcomes an internal spring in
the regulator and fuel is returned to the fuel pump
swirl pot.
14
DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - MEMS
Fuel Pressure Accumulator
Inertia Fuel Shut-Off (IFS) Switch
The fuel pressure accumulator is located on the end
of the fuel rail. The accumulator is connected to the
inlet manifold via a hose. The accumulator is the
same item normally functioning as the pressure
regulator in a feed and return system. In this system,
no return line is fitted and the accumulator simply
serves to damp out injector pulses and reduce
injector noise. The rubber hose connecting the
accumulator to the intake manifold must be
connected at all times to prevent an intake manifold
air leak.
The Inertia Fuel Shut-off (IFS) switch is located in
the engine compartment on the left hand side of the
bulkhead. The switch incorporates a button, covered
by a rubber shroud, which is used to reset the switch
after operation.
The electrical circuit for the fuel pump incorporates
the IFS switch, which in the event of a sudden
deceleration, breaks the circuit to the fuel pump
stopping fuel delivery to the engine. The switch must
be reset by pressing the rubber top before the
engine can be restarted.
WARNING: ALWAYS check for fuel leaks
and the integrity of fuel system
connections before resetting the switch.
Diagnostic Socket
The diagnostic socket is located in a bracket behind
the centre console in the passenger footwell. The
socket connector is constructed to ISO standard and
allows the attachment of TestBook or any other ISO
standard scantool. The diagnostic socket allows
diagnostic information stored in any of the vehicle’s
ECU’s to be retrieved. It also allows engine tuning
and fault diagnosis to be carried out via the ECM.
DESCRIPTION AND OPERATION
15
ENGINE MANAGEMENT SYSTEM - MEMS
Heated Oxygen Sensor (HO2S)
Acceleration Enrichment
The engine management system operates a closed
loop emission system to ensure the most efficient
level of exhaust gas conversion. The HO2S is fitted
in the exhaust manifold and monitors the exhaust
gases.
When the throttle pedal is depressed, the ECM
receives a rising voltage from the TP sensor and
detects a rise in manifold pressure from the MAP
sensor. The ECM provides additional fuel by
increasing the normal injector pulse width and also
provides a small number of extra additional pulses
on rapid throttle openings.
The HO2S supplies a small voltage proportional to
exhaust oxygen content to the ECM. As the air/fuel
mixture weakens, the exhaust oxygen content
increases and the voltage to the ECM decreases. If
the mixture becomes richer, the oxygen content
decreases and the voltage increases.
If the HO2S fails, the ECM enters a default mode
using a substitute value of 100% (open loop).
Over-Run Fuel Cut-Off
The ECM implements over-run fuel cut-off when the
engine speed is above 2000 rev/min with engine at
normal operating temperature and the TP sensor in
the closed position, i.e. the vehicle is ’coasting’ with
the throttle pedal released.
The ECM indexes the IAC valve open slightly to
increase the air flow through the engine to maintain
a constant manifold depression to keep emissions
low. Fuel is progressively reinstated as the throttle is
opened.
From this signal the ECM can determine the air/fuel
mixture being delivered to the engine, and can
adjust the duration the injectors are open to maintain
the ratio necessary for efficient gas conversion by
the catalyst.
The HO2S has an integral heating element to
ensure an efficient operating temperature is quickly
reached from cold. The electrical supply to the
heater element is controlled by the ECM via the
heated oxygen sensor relay in the relay module.
16
DESCRIPTION AND OPERATION
Over-Speed Fuel Cut-Off
To prevent damage at high engine speeds the ECM
will implement fuel cut-off at engine speeds above
7000 rev/min by inhibiting the earth path for the
injectors. As engine speed falls to 6990 rev/min, fuel
is progressively reinstated.
Ignition Switch Off
When the ignition is switched off, the ECM will keep
the main relay energised for approximately 5
minutes while it drives the IAC valve to its power
down position and stores data to permanent
memory, ready for the next engine start. During this
period, the cooling fan(s) may be operated to reduce
engine bay temperature and aid hot starting.
ENGINE MANAGEMENT SYSTEM - MEMS
AIR CONDITIONING/COOLING FANS
Cooling Fans (Vehicles with air conditioning)
Air Conditioning (if fitted) / Fan Control
The ECM controls the operation of the cooling and
the condensor fan. The ECT sensor constantly
sends signal to the ECM. When engine coolant
reaches 112°C, the ECM switches the cooling and
condensor fans on, in fast mode, until the engine
coolant temperature is reduced to 100°C. The
cooling fans will operate at slow speed when A/C is
operating unless overriden by a high temperature,
fast speed request.
On all models, an electric cooling fan is fitted in a
housing at the right hand end of the radiator. Models
fitted with air conditioning have an additional
condensor fan fitted in the housing on the left hand
side of the radiator.
The ECM controls the air conditioning grant output. If
an input is received from the air conditioning select
button, with the interior blower fan on and the trinary
switch set, the ECM will consider engaging the air
conditioning clutch. The ECM considers the coolant
temperature and the throttle position before the air
conditioning grant is operated. When the air
conditioning grant is started, the cooling fans
operate in slow mode, unless the coolant
temperature is above a set value when they operate
in fast mode.
The ECM provides two outputs to control the two
cooling fans; slow mode and fast mode. The modes
of operation vary depending on signals received
from the air conditioning thermostat, the ECT sensor
and the ECM. In slow mode, both fans operate in
series sharing the same electrical feed. In fast
mode, both fans operate in parallel, each fan
receiving its electrical feed from a separate source.
When the ignition is turned off, the fans can continue
to operate for up to eight minutes if the ECT sensor
senses a coolant temperature of 114°C or above.
The fans will turn off when the temperature
decreases to 112°C, or less, or when eight minutes
has elapsed. If a temperature of 114°C is not sensed
within five minutes after ignition off, the fans will not
operate.
HILL DESCENT CONTROL (HDC) SIGNAL
(Vehicles with ABS Only)
The ECM constantly monitors signal information for
throttle position and engine speed and also
assesses other engine inputs to produce an engine
torque signal. These signals, along with engine and
gearbox identifiers, are passed to the ABS ECU to
control hill descent.
Cooling Fan (Vehicles without air conditioning)
See BRAKES, Information.
The ECM controls the operation of the cooling fan.
The ECT sensor constantly sends signals to the
ECM. When engine coolant reaches 106°C, the
ECM switches the cooling fan on, in fast mode, until
the engine coolant temperature is reduced to 100°C
or less.

tray. The air cleaner housing is plastic moulded with
a removable lid which is retained with spring clips.
Removal of the lid allows access to the corrugated
paper filter element.
An air intake pipe is located at the front of the air
cleaner housing and draws air from within the
engine compartment. A rubber hose is connected to
the intake pipe and connects to a resonator box
located in the front left hand wheel arch. The
resonator box is used to reduce induction noise.
The outlet from the housing is connected to the
throttle housing with a flexible rubber hose. The
hose incorporates two plastic tubes which provide
additional reduction in induction noise.

DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - EDC
ELECTRONIC DIESEL CONTROL OPERATION
Main Features
Diesel engines operate by compression ignition. The
rapid compression of air in the cylinder is heated
during the compression cycle. The fuel is injected
into the compressed, heated air and spontaneously
ignites. Automatically controlled glow plugs are used
during cold starting to reduce post start emissions
and assist cold starting by raising the temperature of
the compressed air to ignition point.
The main features are as follows:
• The ECM incorporates short circuit protection
and can store intermittent faults on certain inputs.
TestBook can interrogate the ECM for these
stored faults.
• The engine management system is a ’Drive by
Wire’ system, with no mechanical link between
the throttle pedal and the fuel injection pump. All
throttle movements are monitored by the ECM
via a throttle position (TP) sensor which is
located on the pedal box. The sensor provides
the ECM with a signal proportional to throttle
pedal movement. The ECM then adjusts the fuel
injection pump to deliver the required amount of
fuel.
Electronic Control Module (ECM)
The Electronic Control Module (ECM) processes all
inputs and outputs related to the operation of the
electronic diesel control. The ECM is located on a
mounting plate behind the battery in the engine
compartment. The ECM comprises an aluminium
cast body with a galvanised sealed lid. A socket is
positioned on its upper face and receives a multiplug
from the engine wiring loom. The socket contains 55
pins although only the pins corresponding to those in
the multiplug are used.
The multiplug is connected into the engine
compartment wiring loom. All inputs and outputs to
and from each sensor is transmitted through the
loom and via the multiplug, to the ECM. The
multiplug fits into a corresponding socket on the
upper face of the ECM and is locked in position with
a cam type locking lever. The multiplug pins are
plated to minimise oxidation and give improved
reliability.
The ECM monitors the conditions required for
optimum combustion of fuel in the cylinder through
sensors located at strategic points around the
engine. From these inputs, the ECM can adjust the
quantity and timing of the fuel being delivered to the
cylinder.
• In conjunction with the TP sensor, the ECM uses
engine speed, calculated from the Crankshaft
Position (CKP) sensor, to determine the basic
fuelling requirements of the engine. This basic
calculation is modified using signals from
sensors, strategically positioned around the
engine, to ensure that the correct fuel mixture is
achieved for optimum performance and
emissions.
• If certain system inputs fail, the ECM implements
a back-up facility to enable the system to
continue functioning, although at a reduced level
of performance.
• A separate diagnostic socket, located behind the
centre console in the passenger footwell, allows
engine tuning or fault diagnosis to be carried out
using TestBook.
• The ECM also operates the engine
immobilisation circuits. When the ignition is
switched to position II, a coded signal is sent to
the ECM from the Central Control Unit (CCU). If
the coded signal does not match the signal
programmed into the ECM, the ECM immobilises
the engine starting circuits.
• On vehicles fitted with ABS, the ECM provides
signal information to the ABS ECU for hill
descent control.

ENGINE MANAGEMENT SYSTEM - EDC
Fuel Injection Timing
The ECM determines the optimum fuel injection
timing for the injection pump based on the signals it
receives from the following sensors:
1. Crankshaft Position (CKP) sensor - Engine
speed and crankshaft position
2. Needle lift sensor - Start of injection
3. Engine Coolant Temperature (ECT) sensor Engine temperature
4. Manifold Absolute Pressure (MAP) sensor Engine load
5. Intake Air Temperature (IAT) sensor
Basic Fuel Injection Timing
Crankshaft Position (CKP) sensor
The speed and position of the engine is detected by
the CKP sensor which is bolted to, and projects
through, the gearbox adapter plate adjacent to the
flywheel.
The CKP sensor is an inductive sensor containing a
coil and a permanent magnet which provides a
magnetic field. The sensor is situated such that an
air gap exists between it and the flywheel. Air gap
distance is critical for correct operation.
8
DESCRIPTION AND OPERATION
The flywheel has four poles positioned equally
around the crankshaft circumference at 90 degree
intervals. When the flywheel rotates and a pole
passes the CKP sensor, it disturbs the magnetic
field inducing a voltage pulse in the coil. This pulse
is transmitted to the ECM.
Four pulses are transmitted to the ECM for each
revolution of the flywheel. By calculating the number
of pulses that occur within a given time, the ECM
can determine the engine speed. The output from
this sensor, when used in conjunction with that from
the needle lift sensor, is used for idle stabilisation
and reference for injection timing.
If the CKP sensor fails, the malfunction indicator
lamp on the instrument panel is illuminated. The
ECM enters a default mode and uses signals from
the needle lift sensor to enable the ECM to continue
functioning but with a reduction in engine
performance and a higher than normal idle speed.
Starting difficulties may also be experienced.
ENGINE MANAGEMENT SYSTEM - EDC
Needle lift sensor
Fuel Injection Timing Compensation
The needle lift sensor is located in the No. 1 injector
body. It operates as the other injectors but has a coil
which surrounds the shaft of an extended injection
needle. The coil is fed a DC supply from the ECM
which produces a magnetic field.
Engine Coolant Temperature (ECT) sensor
When the needle is moved under the influence of
fuel pressure, the magnetic field is disturbed which
induces an AC voltage in the coil. The induced
voltage is registered in the ECM as a reference point
for the start of the injection sequence.
The ECT sensor is located in the top of the coolant
outlet elbow which is attached to the front of the
cylinder head. The sensor is screwed into a
threaded port and measures the temperature of
coolant as it leaves the engine via the top hose to
the radiator.
The ECM uses the input signals from the needle lift
sensor, together with a signal from the CKP sensor,
to detect the actual start of injection. The ECM,
using inputs from the other sensors, calculates then
adjusts the injection timing of the fuel pump to
achieve optimum fuelling of the engine.
If the needle lift sensor fails, the malfunction
indicator lamp on the instrument panel is illuminated.
The ECM, which enters a default mode, continues to
function but with a reduction in engine performance
and lack of throttle response.
The ECT sensor is a ’thermistor’ (a temperature
dependent resistor), i.e. the voltage output varies in
proportion to temperature. The ECM constantly
monitors the signal and uses the information to
correct the quantity of fuel injected and the injection
timing especially during cold starting. During starting,
output from the sensor determines the operating
period for the glow plugs.
If the ECT sensor fails, the malfunction indicator
lamp on the instrument panel is illuminated. The
ECM uses a substitute value of -20°C for the
injection timing and uses the fuel temperature to
correct the fuel quantity.
DESCRIPTION AND OPERATION
9
ENGINE MANAGEMENT SYSTEM - EDC
Intake Air Temperature (IAT) sensor
The IAT sensor is located in the right hand side of
the inlet manifold. This sensor is of the negative
temperature coefficient type, designed to reduce its
resistance with increasing temperature.
The ECM receives a signal proportional to the
temperature of the intake air. When used in
conjunction with the signal from the manifold
absolute pressure (MAP) sensor and the CKP
sensor, the ECM can calculate the volume of oxygen
in the air and adjust the quantity of fuel being
injected to achieve optimum fuelling of the engine.
Manifold Absolute Pressure (MAP) sensor
The MAP sensor is located on the bulkhead and is
connected, via a pressure tube, to the outlet side of
the turbocharger.
The MAP sensor is a strain gauge type sensor and
monitors the intake air pressure. The sensor is
connected electrically to the ECM.
10
DESCRIPTION AND OPERATION
The sensor comprises a plastic body containing a
pressure detection chamber. The pressure detection
chamber consists of four individual sensors made
from glass panels with Silicon diaphragms. The
Silicon diaphragms contain resistors which are
bonded to the glass panels forming an enclosed
vacuum.
When the intake air pressure changes, pressure in
the detection chamber causes the diaphragms to
deflect. The deflection of the diaphragms alters the
length of each resistor, changing their resistance.
This change in resistance is converted into an
analogue output signal of between 0V and 5V within
the pressure sensor. The ECM outputs a reference
signal of 5V to the MAP sensor. The ECM compares
the output from the MAP sensor to the reference
signal and converts the difference into a pressure
value.
Manifold absolute pressure, when used in
conjunction with the signal from the IAT sensor and
the CKP sensor, allows the ECM to accurately
calculate the volume of oxygen in the air and adjust
the quantity of fuel being injected to achieve
optimum fuelling of the engine.
If the MAP sensor fails, the malfunction indicator
lamp on the instrument panel is illuminated. The
ECM uses a substitute value of 45.5 kPa (6.6 lbf/in2)
which limits the fuel quantity to 21 mg/stroke
resulting in a reduction in engine performance.
ENGINE MANAGEMENT SYSTEM - EDC
Vehicle Speed Sensor (VSS)
The VSS is located on the top face of the gearbox
housing at the rear of the engine. The VSS is driven
by a shaft from the final drive gear where it is
converted into an electrical signal proportional to
road speed.
The output from the VSS is used to drive the
instrument panel speedometer in addition to
providing a signal to the ECM. The ECM uses this
signal, along with other inputs, to provide active
surge damping, adjust idle stabilisation and the
quantity of fuel being delivered to the injectors.
On vehicles fitted with ABS, the speed sensor is not
fitted. A dummy sensor is fitted to blank the sensor
port. The ECM and the speedometer receive their
signals from the ABS ECU, which it calculates from
each ABS wheel sensor.
If the VSS fails, the malfunction warning lamp on the
instrument panel is illuminated. The ECM uses a
substitute value of 1.8 mph (3 km/h), active surge
damping is removed and the air conditioning (if
fitted) is inoperable.
Throttle Position (TP) sensor
The TP sensor is mounted on the pedal box and is
connected by a linkage to the throttle pedal.
Movements of the throttle pedal are sensed by the
TP sensor and a signal sent to the ECM.
The engine management system is a ’Drive by Wire’
system. The throttle pedal is not physically
connected to the fuel injection pump by a
mechanical linkage as in a traditional injection
system, but instead the amount of fuel injected is
controlled entirely by the ECM.
The TP sensor consists of a thick film potentiometer
together with a sender switch. With the throttle pedal
at rest the switch is open. The sender switch signal
from the potentiometer is used by the ECM to
implement idle speed control and over-run fuel
shut-off. When the throttle pedal has been moved
enough to rotate the potentiometer more than 9
degrees, the switch closes.
When the potentiometer is moved, the sender switch
signals a logic input to the ECM. The ECM then
checks the voltage signal from the potentiometer.
This voltage is compared with a pre-programmed
value to check the potentiometer is working
correctly.
DESCRIPTION AND OPERATION
11
ENGINE MANAGEMENT SYSTEM - EDC
Throttle pedal movement causes voltage across the
potentiometer to vary. The ECM calculates the rate
of change of the voltage signal in positive
(acceleration) or negative (deceleration) directions.
From this, the ECM can determine the required
engine speed, rate of acceleration or deceleration
and apply acceleration enrichment, deceleration fuel
metering, or over-run fuel cut-off.
The ECM calculates the ’maximum allowable fuel
quantity’ from the input signal according to strategies
such as smoke limitation and active surge damping
to calculate the final figure. If the signal from the
throttle potentiometer is smaller than the maximum
allowable quantity, then the requested quantity will
be injected. However, if the requested quantity is
greater than the maximum allowable quantity, then
the maximum allowable quantity will be injected
rather than that demanded.
Glow plug relay
The glow plug relay is located behind the battery
tray, below the engine compartment fuse box.
When the starter switch is turned to position ’II’, the
ECM energises the glow plug relay and illuminates
the glow plug warning light on the instrument panel.
The glow plug relay supplies a current from the
battery to the four glow plugs to reduce post start
emissions and assist cold starting by raising the
temperature of the compressed air to ignition point.
Glow plugs
If the TP sensor fails, the malfunction indicator lamp
on the instrument panel is illuminated. The ECM
limits the engine speed to 1060 rpm and the air
conditioning (if fitted) is inoperable.
Brake pedal switch
The four glow plugs are located in the forward face
of the cylinder head below their respective injector.
Each glow plug draws a current of 23 to 25 Amps.
The current draw has a linear decline to 11 Amps as
the glow plug warms.
The brake pedal switch is mounted on the pedal
box. The switch informs the ECM when the vehicle
is braking and allows it to implement active surge
damping and over-run fuel cut-off.
The ECM has one brake input which is monitored for
plausibility with the TP sensor. If the brake pedal
switch fails, there will be no effect on the engine
management system.
12
DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - EDC
The operating period of the glow plugs is dependent
upon the initial engine temperature determined by
the ECM from the ECT sensor. Once the glow plugs
have operated for their pre-determined time, the
ECM will remove the supply from the glow plug relay
and extinguish the glow plug warning light on the
instrument panel. Glow plug operation times are as
follows (times are approximate):
Temperature
Time
+30°C
2.0 Seconds
+10°C
3.6 Seconds
0°C
4.5 Seconds
-5°C
5.0 Seconds
-7.5°C
5.5 Seconds
-10°C
7.0 Seconds
-12°C
9.0 Seconds
-15°C
11.0 Seconds
-20°C
15.0 Seconds
The ECM can keep the glow plugs on for a short
period of time to assist with smooth running and to
aid initial driveaway. The time for glow plug
operation after the engine is started is dependant on
coolant temperature.
With a coolant temperature of 85°C, the ECU will
keep the glow plugs on for approximately 2.0
seconds. In very cold conditions, if the ECT sensor
reads a coolant temperature of - 25°C, the supply to
the glow plugs can remain connected for up to 100
seconds. The supply to the glow plugs is removed if
the fuelling to each cylinder exceeds 20 mg/stroke or
the engine speed exceeds 1656 rpm.
Mass Air Flow (MAF) sensor
The MAF sensor is located in the air cleaner outlet
pipe. The mass air flow is determined from the
cooling effect of inlet air flowing over a Hot Film
sensor. This signal is fed back to the ECM where it
is used to monitor the recirculation of exhaust gases.
An increase in the exhaust gas recirculation reduces
the amount of intake air being drawn into the
system, thereby reducing the cooling effect of the
Hot Film resistor.
Diagnostic Socket
The diagnostic socket is located behind the centre
console in the passenger footwell. The diagnostic
socket is provided to enable diagnosis via TestBook
to be carried out and to allow interrogation of the
ECM for triggered fault codes.
DESCRIPTION AND OPERATION
13
ENGINE MANAGEMENT SYSTEM - EDC
Malfunction Indicator Lamp (MIL)
The ECM has a built in self-diagnosis function. If
certain faults are detected, the MIL in the instrument
panel will illuminate, and the ECM will implement a
back-up facility to enable the system to continue
functioning, though at a reduced level of
performance.
Minor faults will not illuminate the MIL, but will be
stored in the ECM’s memory and can be retrieved at
a later date using TestBook. If a serious fault is
detected, the warning light will illuminate and the
engine management system will shut down,
preventing the vehicle from being started or driven.
The MIL will remain illuminated until the starter
switch is turned off. If the fault is still present when
the starter switch is turned back on the MIL will
illuminate. If the fault is not present when the starter
switch is turned on, the MIL will remain extinguished,
but a fault code will remain stored in the ECM’s
memory.
Cooling fans (all models)
On all models, two electric cooling fans are fitted in a
housing behind the radiator.
The ECM controls the operation of the cooling fans.
The ECT sensor constantly sends signals to the
ECM. When engine coolant reaches a temperature
of 106°C, the ECM switches the cooling fans on, in
slow mode. When the engine coolant reaches a
temperature of 112°C, the ECM switches the cooling
fans from slow to fast mode. When the engine
coolant temperature is reduced to 106°C, the ECM
switches the cooling fans to operate in slow mode
until the temperature is reduced to below 100°C,
when the ECM switches the fans off. When the
ignition is turned off, the fans stop.
14
DESCRIPTION AND OPERATION
Cooling fans (Vehicles with air conditioning
(A/C) only)
The ECM controls the A/C grant output. If an input is
received from the A/C system the ECM will consider
engaging the A/C clutch. The ECM considers the
coolant temperature and the throttle position before
the A/C grant is operated. When the A/C grant is
started, the cooling fans turn on in slow mode,
unless the coolant temperature is above 112°C
when they operate in fast mode.
The ECM provides two outputs to control the two
cooling fans; slow mode and fast mode. The modes
of operation vary depending on signals received
from the A/C thermostat, the ECT sensor and the
ECM. In slow mode, both fans operate in series
sharing the same electrical feed. In fast mode, both
fans operate in parallel, each fan receiving its feed
from a separate source. When the ignition is turned
off, both fans stop.
If an engine temperature of 117°C is sensed by the
ECT sensor, the ECM can override the A/C request
to reduce load on the engine. The air conditioning
request is reinstated when the coolant temperature
reaches a 115°C.
Hill descent control signal (Vehicles with ABS
only)
See BRAKES, Information.
The ECM constantly provides signal information of
throttle position and engine speed and also
assesses other engine inputs to produce an engine
torque signal. These signals, together with engine
and gearbox identifiers, are passed to the ABS ECU
to control hill descent.
ENGINE MANAGEMENT SYSTEM - EDC
FUEL SYSTEM
Fuel is drawn from the tank by the Fuel Injection
Pump (FIP) via a filter, located in the engine
compartment, which removes particle contamination
from the fuel.
The FIP meters a precisely timed, exact quantity of
fuel into the injectors in response to throttle
variations, injection timing varying with engine
speed.
Any excess fuel delivered to the FIP is not injected,
but passed back to the tank via a fuel return line.
Fuel is injected directly into the cylinder head where
it ignites. A swirl chamber, machined into the piston
crown, promotes efficient mixing of the fuel with the
already compressed air. The burning fuel expands
rapidly in the combustion chamber, creating extreme
turbulence which further mixes the burning fuel with
the compressed air, providing complete combustion
and reducing emissions.

DESCRIPTION AND OPERATION
15
ENGINE MANAGEMENT SYSTEM - EDC
The FIP is a vane-type pump, which is belt driven
from the rear end of the camshaft. Fuel delivery from
the pump to the injectors is regulated by the
movement of a control spool.
Quantity servo control unit
Movement of the control spool increases or
decreases the fuel delivery rate to meet engine
operating requirements.
The pump houses the following components which
either provide feed back to, or are controlled by, the
ECM:
Engine Fuel Temperature (EFT) sensor
Fuel temperature is monitored by an EFT sensor
located in the FIP. This sensor is of the negative
temperature coefficient (NTC) type, designed to
reduce its resistance with increasing temperature.
The sensor is connected to earth and to a precision
resistor inside the ECM. A small current is fed
through the resistor.
When the system is operating, the ECM regularly
checks the sensor voltage which changes with fuel
temperature. This is converted to a digital word that
can be read by the microprocessor and converted to
a temperature reading. As fuel density varies with
temperature, the information received is used to
calculate the correct quantity of fuel to inject.
If the fuel temperature sensor fails, the malfunction
indicator light on the instrument panel will illuminate.
The ECM uses a substitute value of 60°C and slight
effects on fuelling may occur.
The servo control unit is used to accurately control
the amount of fuel delivered to the injectors. The unit
consists of a rotary magnet mounted on an eccentric
shaft; the shaft engages with the control spool (3) of
the pump.
The rotary magnet is fitted with a return spring (4)
and moves under the influence of a control coil (2).
The magnet rotates through an arc of about 60
degrees moving the control spool from the closed
position to the maximum fuel delivery position. The
eccentric shaft engages with the control spool at one
end, while the opposite end operates a rotary
potentiometer (1).
When the control coil is energised the rotary magnet
and eccentric shaft move against spring pressure.
Rotary movement of the eccentric shaft is converted
into linear movement of the control spool. This
allows more fuel to be delivered to the injectors.
When the control coil is de-energised the return
spring causes the rotary magnet and eccentric shaft
to resume their original position. The control spool is
moved to the closed position.
16
DESCRIPTION AND OPERATION
ENGINE MANAGEMENT SYSTEM - EDC
Quantity servo potentiometer
Mounted at the top of the servo control unit is a
rotary potentiometer. As the eccentric shaft of the
servo control unit moves, the wiper of the
potentiometer is moved across the resistive part of
the potentiometer. The voltage output from the
potentiometer is proportional to the position of the
control spool. From this input the ECM can calculate
the quantity of fuel being delivered by the pump and
adjust the amount of fuel being delivered by
energising the control coil to move the control spool.
Injection timing device
With the engine stopped and the solenoid
de-energised, the plunger (1) is in the fully retarded
position. When the engine is started, the fuel
pressure (4) passes through the plunger (1) and acts
on the plunger face. Simultaneously, the solenoid (2)
is energised by the ECM. Depending on the signals
received from the sensors, the solenoid (2) is
energised for varying lengths of time. This allows the
fuel pressure (5) at the plunger face to relieve to the
spring side of the plunger, which is at pump inlet
pressure (5), retarding the injection timing. As the
plunger moves, a cam plate, connected to the
plunger via a pin, moves and adjusts the injection
timing. The ECM continually modulates the solenoid,
advancing or retarding the injection timing to achieve
the optimum timing position.
The ECM receives a feedback signal from the
needle lift sensor and will attempt to correct the
injection timing accordingly by altering the signal to
the solenoid (2). If a change does not occur or
differs by a substantial amount, the ECM will
assume a fault exists and reduce the amount of fuel
injected.

Pump feed pressure
Pump internal pressure
The injection timing device consists of a spring
loaded plunger and a solenoid. The spring loaded
plunger acts against a cam plate driven by the FIP
shaft. The spring loaded plunger moves under the
influence of the pump working pressure.
The injection timing solenoid is responsible for the
characteristic ’buzzing’ sound when the ignition is
turned on. The solenoid operates at 50 Hz and by
varying the operating duration, the advance/retard of
the fuel injection point can be adjusted.
DESCRIPTION AND OPERATION
17
ENGINE MANAGEMENT SYSTEM - EDC
Fuel cut-off solenoid
EXHAUST GAS RECIRCULATION (EGR)
During certain running conditions the EGR system
directs exhaust gases into the intake manifold to be
used in the combustion process. The principal effect
of this is to reduce combustion temperatures, which
in turn reduces Oxides of Nitrogen (NOx) emissions.
The ECM controls an EGR modulator valve mounted
on the bulkhead. This valve, when modulated, opens
the exhaust EGR valve and directs exhaust gases
into the inlet manifold.
The fuel cut-off solenoid is located in the high
pressure section of the FIP. When the ignition is
switched on the ECM sends a signal to the solenoid.
The solenoid energises opening a valve allowing
fuel to flow.
When the ignition is switched off, or in the event of a
serious engine problem, the ECM will remove the
supply to the solenoid, closing the valve and cutting
off the fuel supply to the injectors.
18
DESCRIPTION AND OPERATION
See EMISSION CONTROL, Description and

ENGINE MANAGEMENT SYSTEM - EDC
AIR INTAKE SYSTEM
The engine is supplied with pre-compressed air by a
single stage Garrett GT1549 turbocharger. The
turbocharger is mounted on the left hand end of the
exhaust manifold at the rear of the engine.
With the engine operating under load, exhaust
gases pass into the turbine side of the turbocharger
causing the turbine to rotate, driving a compressor
mounted on the turbine shaft in the intake side of the
turbocharger. Intake air is drawn through the air
cleaner to the turbocharger, where it is compressed
by the compressor. The compressed air is then fed
into the inlet manifold via an intercooler, which
reduces the temperature of the compressed air,
increasing its density still further.
DESCRIPTION AND OPERATION
19
ENGINE MANAGEMENT SYSTEM - EDC
Turbocharger
Intercooler
The turbocharger unit is located at the left hand end
of the exhaust manifold and comprises a die cast
housing and a pneumatic actuator.
The housing contains a turbine on a shaft which is
driven by exhaust gases. At one end of the turbine
shaft is a compressor, mounted on the intake side of
the turbocharger. The housing has two main ports.
One port receives exhaust gases from the manifold
and the other receives clean air from the air filter.
Two smaller ports provide an air pressure feed of
clean air to the wastegate actuator and the MAP
sensor.
The intercooler is positioned at the front of the
vehicle to the left of the radiator and is mounted in
rubber bushes located on the front body cross
member and the bonnet locking platform. The
intercooler is an aluminium cross flow construction
with plastic mouldings at top and bottom. The plastic
mouldings each incorporate a hose connection port.
The MAP sensor, which is located on the bulkhead,
is used to detect intake air pressure changes which
enable the ECM to calculate the volume of oxygen in
the intake air.
Two oil lines provide lubrication for the turbocharger.
A small diameter pipe supplies oil under pressure
from the engine oil pump. A larger pipe provides the
oil return from the turbocharger to the cylinder block.
20
DESCRIPTION AND OPERATION
The intercooler receives a compressed air/exhaust
gas mixture from the turbocharger via a hose to the
bottom connection port. The top connection port,
supplies cooled, compressed air/exhaust gas
mixture from the intercooler to the engine inlet
manifold via a hose. The intercooler reduces the
temperature of the compressed air from the
turbocharger which increases the air density.
ENGINE MANAGEMENT SYSTEM - EDC
Boost control
Air cleaner
Boost control is achieved by a wastegate actuator
operating a mechanical flap, known as a wastegate,
situated in the turbocharger. When operated, the
wastegate allows exhaust gases to bypass the
turbine side of the turbocharger, so decreasing the
rotational speed of the turbine thereby reducing the
pressure of the intake air.
The wastegate actuator consists of a diaphragm
connected to a mechanical linkage which is opposed
by an internal spring. Pressure from the compressor
side of the turbocharger is applied to the actuator via
a sensing pipe. The pressure acting on the actuator
diaphragm builds up until it exceeds the opposing
force of the internal spring (approx. 17 psi or 1.2
Bar) causing the mechanical linkage to move,
thereby opening the wastegate on the turbocharger
and so reducing the boost pressure. As boost
pressure is reduced the mechanical linkage will
move the other way closing the wastegate allowing
the pressure to increase again. With the engine
under significant load the wastegate actuator will be
constantly opening and closing the wastegate.
The air cleaner housing is located on the left hand
side of the engine bay. The air cleaner housing is
plastic moulded with a removable lid which is
retained with spring clips. Removal of the lid allows
access to the corrugated paper filter element.
An air intake pipe is located at the front of the air
cleaner housing and draws air from within the
engine compartment. A rubber hose is connected to
the intake pipe and connects to a resonator box
located in the front left hand wheel arch. The
resonator box is used to reduce induction noise.
The outlet from the air cleaner housing has a plastic
pipe which provides the location for the mass air
flow sensor. The outlet pipe is sealed to the housing
with an O-ring seal. A gauze filter in the pipe
provides additional contamination protection.
A rubber hose connects the outlet pipe to the
turbocharger. The rubber hose also connects a
breather from the camcover to the air intake system.
A plastic tube connected to the rubber hose provides
additional reduction of induction noise.

FUEL SYSTEM
The fuel delivery system major components
comprise a fuel tank, a fuel pump and four injectors.
Fuel Tank
The fuel tank is located on the underside of the
vehicle, forward of the rear suspension subframe.
The tank is constructed from moulded plastic and is
retained by a tubular cradle which is secured to the
vehicle floorpan with four bolts. The fuel tank has a
capacity of 60 litres (13.2 Gallons).
A reflective metallic covering shields the tank from
heat generated from the exhaust system. An
aperture in the top surface of the tank allows for the
fitment of the fuel pump.
The fuel tank filler is located on the right hand rear
wing panel and is protected by a lockable plastic
cap. A plastic tube from the filler is connected to the
tank by a flexible rubber tube. A vent pipe is
connected to the neck of the filler to vent fuel vapour
during filling of the tank. A smaller vent pipe is also
connected to the tank and vents fuel vapour from the
tank to a charcoal cannister located in the engine
compartment.

FUEL DELIVERY SYSTEM
Fuel Pump
Injectors
The fuel pump is electrically operated and is located
in the top face of the fuel tank. A notched locking
ring retains the fuel pump in the tank and requires a
special tool for removal and installation. The fuel
pump is housed in a plastic body which incorporates
coarse and fine filters. The fuel pump is located in a
larger housing which is the swirl pot. The swirl pot
maintains a constant fuel level at the pump pick-up.
Four injectors held between the fuel rail and the inlet
manifold. The injectors are sealed to the fuel rail and
the inlet manifold by O-ring seals. Each injector
supplies one cylinder with fuel. The injectors receive
pressurized fuel from the fuel pump via the fuel rail.
The Engine Control Module (ECM) is responsible for
the timed injection duration of each injector. The
injectors supply a finely atomized spray of the fuel
into the cylinder which is mixed with the air prior to
ignition.
A pressure regulator which regulates the pressure
output of the pump to 3.5 bar is located in the pump
housing.
If the pressure exceeds this setting the regulator
relieves excess pressure back to the swirl pot. This
ensures that the fuel rail and the injectors are
supplied with a constant pressure.
An access panel below the rear passenger seats
provides access to the fuel pump for maintenance.
The top face of the fuel pump has an electrical
connector which supplies power and ground to the
pump and the rotary potentiometer for the fuel
gauge. Two quick fit couplings provide attachment
for the fuel feed and the vent pipes.
Accumulator
An accumulator is attached to the right hand end of
the fuel rail. The accumulator acts as a damper to
damp pulses from the pump and ensure that the fuel
pressure in the rail and to the injectors is constant.
The accumulator is connected by a pipe to the inlet
manifold from which it receives a vacuum to aid the
damping process.
Fuel Filter
A fine mesh filter is fitted within the fuel pump
assembly. This should be renewed at 120,000 mile
(200,000 km) intervals.

An aperture in the top surface of the tank allows for
the fitment of the fuel pick-up and potentiometer. A
notched ring retains the fuel pick-up and
potentiometer in the tank and requires a special tool
for removal and installation. The fuel pick-up
incorporates a swirl pot which maintains a constant
fuel level around the pick-up.

DESCRIPTION AND OPERATION
5
FUEL DELIVERY SYSTEM
Fuel Injection Pump
Injectors
The fuel injection pump is a vane type pump, which
is located on the front of the engine and driven by a
belt from a pulley on the camshaft. The fuel injection
pump draws fuel from the tank through a rubber pipe
and the fuel filter. From the fuel filter, the fuel is
drawn through a fuel cooler, located behind the
bonnet locking platform, to the pump. The fuel
injection pump delivers a precisely timed and
metered quantity of fuel to each injector. The rubber
fuel feed and return pipes connect to metal pipes
which are routed around the engine.
Three injectors and an injector incorporating a
needle lift sensor are fitted to the cylinder head.
Each injector supplies fuel to one cylinder and is
retained in its port in the cylinder head with a clamp
and bolt arrangement.
Any excess (leak-off) fuel delivered to the pump and
injectors is returned to the fuel tank through a rubber
return pipe. The returned fuel is delivered to the tank
through a port in the fuel pick-up and delivered to
the swirl pot.
Fuel Filter
The fuel filter is located in the engine compartment
on the left hand side of the bulkhead. Two
connections on the top face allow for the fitment of
the hoses from the the fuel tank and to the fuel
injection pump.
A screw located on the bottom surface allows for
drainage of the filter to remove moisture and particle
contamination. The feed hose from the filter
incorporates a bulb type handpump. The handpump
is used, in conjunction with a filter bleed screw on
the top face of the filter, to prime the filter and the
fuel line after servicing.
6
DESCRIPTION AND OPERATION
The injectors receive fuel at pressure from the fuel
injection pump. Each injector has a nozzle with five
spray orifices. The orifices protrude into the
combustion chamber and spray fuel into the
chamber, atomizing the fuel and mixing it with the air
prior to combustion.

COOLING SYSTEM - ’K’ SERIES
The cooling system employed is the by-pass type,
allowing coolant to circulate around the engine and
the heater circuit while the thermostat is closed.
The thermostat is installed in a housing which is
attached to the coolant pump. The thermostat is
located in the inlet side of the cooling circuit, which
provides a more stable control of the coolant
temperature in the engine.
When cold, the thermostat is closed and coolant is
prevented from circulating through the radiator.
Coolant is able to circulate through the bypass and
heater circuits.
As the temperature increases, the thermostat
gradually opens, bleeding cool fluid from the radiator
bottom hose into the cylinder block and allowing hot
coolant to flow to the radiator through the radiator
top hose, balancing the flow of hot and cold fluid to
maintain the optimum operating temperature. When
the thermostat opens fully, the full flow of coolant
passes through the radiator.
An expansion tank is fitted to the right hand shock
absorber mounting. Any excess coolant, created by
heat expansion, is returned to the expansion tank
through bleed lines from the top of the radiator and
from the cylinder block. The expansion tank has an
outlet pipe which is connected into the coolant
circuit. The outlet pipe supplies coolant into the
system when the engine is cool. This replaces
coolant displaced to the expansion tank due to heat
expansion.
For additional air flow through the radiator matrix,
particularly when the vehicle is stationary, an electric
cooling fan is fitted to the rear of the radiator. The
temperature of the cooling system is monitored by
the Engine Control Module (ECM) via signals from a
temperature sensor, which is mounted in a housing
attached to the cylinder head. When a temperature
of 102°C is reached the ECM switches the cooling
fan on via a relay. The fan switches off at 96°C.
Vehicles fitted with air conditioning have 2 fans.
These operate either in series or parallel according
to engine coolant temperature or air conditioning
requirements. The fan operation is controlled by the
ECM. The fans operate in series (slow mode) when
a temperature of 106°C or higher is sensed. When a
temperature of 112°C is sensed, the fans switch
from series to parallel operation (fast mode). When
the temperature falls to 106°C or below, the fans are
switched back to series operation. The fans stop
when a temperature of 100°C or lower is sensed.
The cooling system is also used to cool the
Intermediate Reduction Drive (IRD). The IRD oil is
cooled with fluid from the cylinder block. The fluid
passes through a plate which contains waterways
and recirculates via the heater circuit.
Bleed screws are installed in the top hose of the
heater matrix and the feed pipe to the coolant pump.
These are used to bleed air from the cooling system
during system filling.
The coolant is circulated by a rotor type pump. The
pump is mounted at the rear of the engine and is
driven by a geared pulley from the camshaft timing
belt. The pump draws coolant from the radiator
bottom hose and circulates it through the engine and
heater circuit.
The radiator, positioned at the front of the vehicle, is
a copper/brass cross - flow type with moulded
plastic end tanks. The radiator is mounted in rubber
bushes; the bottom of the radiator is located in the
front body cross member, and the top is located in
the bonnet locking platform. The top hose from the
radiator is connected to the temperature sensor
housing and bottom hose is connected, via a pipe, to
the thermostat housing.

side of the cooling circuit, which provides a more
stable control of the coolant temperature in the
engine.
When cold, the thermostat is closed and coolant is
prevented from circulating through the radiator.
Coolant is able to circulate through the bypass and
heater circuits.
As temperature reaches 80-84 °C, the thermostat
gradually opens, bleeding cool fluid from the radiator
bottom hose into the cylinder block and allowing hot
coolant to flow through the heater circuit and to the
radiator through the radiator top hose, balancing the
flow of hot and cold fluid to maintain the optimum
operating temperature. When the thermostat opens
fully, at 96 °C the full flow of coolant passes through
the radiator.
An expansion tank is fitted to the right hand shock
absorber mounting. Any excess coolant, created by
heat expansion, is returned to the expansion tank
through a bleed line from the top of the radiator. The
expansion tank has an outlet pipe which is
connected into the coolant circuit. The outlet pipe
supplies coolant into the system when the engine is
cool. This replaces coolant displaced to the
expansion tank due to heat expansion.
The coolant is circulated by a rotor type pump. The
pump is mounted on the rear face of the PAS pump
which is driven by a drive belt. The mounting for the
pump is sealed to a port on the cylinder block. The
pump draws fluid from the oil cooler and and the
heater circuit and circulates it through the the engine
via the port on the cylinder block.
For additional air flow through the radiator matrix,
particularly when the vehicle is stationary, an electric
cooling fan is fitted to the rear of the radiator. The
temperature of the cooling system is monitored by
the Engine Control Module (ECM) via signals from a
twin terminal temperature sensor, which is mounted
in the top face of the coolant outlet elbow. When a
temperature of 106°C is reached, the ECM switches
the cooling fan on via a relay. The fan switches off at
99°C. The coolant outlet elbow also houses a single
terminal sensor which provides a coolant
temperature output to the instrument panel
temperature gauge.
All vehicles have two fans. These operate either in
series or parallel according to engine coolant
temperature or air conditioning requirements. The
fan operation is controlled by the ECM. The fans
operate in series (slow mode) when a temperature
of 106°C or higher is sensed. When a temperature
of 112°C is sensed the fans switch from series to
parallel operation (fast mode). When the
temperature falls to 106°C or below, the fans are
switched back to series operation. The fans stop
when a temperature of 100°C or lower is sensed.
The cooling system is also used to cool the engine
oil, the Intermediate Reduction Drive (IRD) and the
Exhaust Gas Recirculation (EGR) cooler:
An oil cooler is located at the front of the engine
cylinder block. A housing at the bottom of the oil
cooler contains the system thermostat and also
provides the connection for the bottom hose from
the radiator. A connection at the top of the oil cooler
has two ports; one port supplies coolant from the
cooler to the pump and the other port provides the
by-pass circuit from the outlet elbow hose. Coolant
from the radiator enters the oil cooler body through
the thermostat housing and passes through the body
of the oil cooler, reducing the engine oil temperature.
The radiator, positioned at the front of the vehicle, is
a copper/brass cross - flow type with moulded
plastic end tanks. The radiator is mounted in rubber
bushes; the bottom of the radiator is located in the
front body cross member, and the top is located in
the bonnet locking platform. The top hose from the
radiator is connected to the coolant outlet elbow on
the front of the cylinder head and the bottom hose is
connected to the thermostat housing.
DESCRIPTION AND OPERATION

COOLING SYSTEM - ’L’ SERIES
The IRD oil cooler is located on the end face of the
IRD and comprises a plate, sealed into the end face
of the IRD gearbox housing. Coolant from the
cylinder block passes through the plate which
contains waterways and recirculates via the heater
circuit. The coolant supply from the cylinder block
flows through a brass connection on the rear of the
cylinder block. The connection contains a
thermostatically controlled restrictor which controls
the flow of coolant to the IRD cooler at certain
coolant temperatures. The thermostatic restrictor
opens at between 80-84°C and is fully open at
96°C.
The EGR cooler, is located at the rear of the engine
and is mounted on the exhaust manifold. The EGR
cooler comprises a cylinder, closed at each end with
two connection ports. The EGR cooler contains
hollow tubes which allow the exhaust gases to pass
through the cylinder. The coolant from the heater
circuit flows into the lower connection on the cooler,
around the hollow tubes cooling the exhaust gases,
and flowing out of the upper connection back into
the heater circuit.
A bleed screw is installed in the top hose to the
heater matrix. This is used to bleed air from the
cooling system during system filling.

CLUTCH SYSTEM DESCRIPTION
The clutch system is a conventional diaphragm type
clutch operated by a hydraulic cylinder. The
hydraulic system is manufactured from plastic and is
sealed for life and can only be replaced in its
entirety. The clutch requires no adjustment to
compensate for clutch wear.
Hydraulic Clutch
The hydraulic clutch comprises a master cylinder
and a slave cylinder connected by a plastic tube.
The system comes as a complete assembly, pre
filled with hydraulic fluid to ease replacement and
minimize repair times. The master and slave
cylinders are manufactured from injection moulded
thermoplastic which can operate in extremes of
temperatures. The hydraulic clutch system is self
bleeding.
The master cylinder is mounted in the bulkhead. It
locates in a specially designed hole which allows the
master cylinder to be installed in the hole at a 45
degree angle from vertical. Once located, the master
cylinder is rotated to the vertical position and is
automatically secured in this position. The master
cylinder has a piston which moves in the cylinder. A
rod is attached to the piston and attaches to a spigot
on the clutch pedal. A fluid reservoir is mounted on
the engine compartment side of the master cylinder
and is sealed with a removable rubber cap.
A nylon tube is connected to the master cylinder by
a swivel coupling which aids installation and
alignment. The other end of the tube is connected to
the slave cylinder, also using a swivel coupling. The
nylon tube is flexible and allows ease of routing and
absorbs engine movements and vibrations.
2
DESCRIPTION AND OPERATION
The slave cylinder comprises a cylinder with a piston
and rod. The piston is spring loaded to return to its
fully extended position when at rest. A new slave
cylinder has the piston locked in the retracted
position by a plastic clip. When the clutch is first
operated, the hydraulic action of the clutch system
breaks the plastic clip and allows the rod to extend.
The plastic clip attached to the end of the rod
locates in a spherical seat in the release lever. The
slave cylinder is located in a bracket which is bolted
to the gearbox. A specially shaped slot in the
bracket locates the slave cylinder and a plastic clip
secures it in position.
Clutch Mechanism
The clutch mechanism comprises a flywheel, drive
plate, pressure plate, release lever, release fork and
a release bearing. The clutch mechanism is fully
enclosed at the end of the engine by a bell housing
formed by the gearbox casing.
The spindle of the release lever is located through
machined bores in the gearbox casing. The release
fork fits on the release lever spindle and is secured
to the spindle with a bolt and spring washer. An oil
seal is located at the outer face of the gearbox
casing and seals against the release lever spindle
preventing the ingress of dirt and moisture.
A release bearing is operated by the release fork.
The bearing has two lugs which clip onto the forks of
the release fork.
The flywheel is bolted to the flange of the engine
crankshaft with six bolts. A dowel ensures that the
flywheel is correctly located. A ring gear is located
on the outside diameter of the flywheel and is seated
against a flange. The ring gear is an interference fit
on the flywheel and is installed by heating the ring
gear and cooling the flywheel. The ring gear is a
serviceable item and can be replaced if damaged or
worn.
CLUTCH
The operating face of the flywheel is machined to
provide a smooth surface for the drive plate to
engage on. Three dowels are fitted to the outer
diameter of the flywheel and provide for the location
of the pressure plate. Six threaded holes provide for
the attachment of the pressure plate. The flywheel is
balanced to ensure that it does not produce vibration
when rotating.
The pressure plate comprises a diaphragm,
pressure plate and cover. The pressure plate is
mounted on and rotates with the flywheel. Three
dowels locate the cover and six bolts secure it to the
flywheel. The same 228 mm (9.0 in) diameter plate
is used on K and L Series engines.
The pressure plate is forged from cast iron and
machined to provide a smooth surface for the drive
plate to engage on. Three lugs on the outer diameter
of the pressure plate connect it via three leaf springs
to the cover. The leaf springs have three tempered
steel leaves and pull the pressure plate away from
the drive plate when the clutch pedal is depressed.
The cover is made from pressed steel.
The diaphragm comprises a cast ring with eighteen
fingers on its inner diameter. Two circular steel
fulcrum rings are attached to the housing and allows
the diaphragm to pivot between them. The
diaphragm is not physically attached to the pressure
plate. When pressure is applied to the diaphragm
fingers from the release bearing, the diaphragm
pivots between the fulcrum rings and moves away
from the pressure plate. The leaf springs attaching
the pressure plate to the cover move the plate away
from the drive plate.
The drive from the inner plate is transferred to the
central plate through the larger compression springs.
Two outer plates are located either side of the
central plate. The central plate is connected to the
outer plate in slots and retained with rivets. The slots
allow the central plate to move and compress the
springs absorbing shock loads when the clutch is
engaged or when the engine is decelerating. One of
the outer plates is marked ’flywheel side’. This outer
plate must face the flywheel when installed.
One of the outer plates has a spring steel plate
riveted to it. The plate provides the attachment
surface for the clutch drive plate friction material
which is riveted to each side of the plate.
The facing material comprises two discs which are
riveted to each side of the spring steel plate. The
rivets are secured through recessed holes in the
facing material and emerge in clearance holes in the
opposite disk.
The drive plates used K and L Series engines are
both of the compound centre type. The compound
centre drive plate allows angular movement of the
hub at low torque levels. The K Series drive plate is
215 mm (8.5 in) diameter and has a facing material
manufactured from Raybestos K202. The L Series
drive plate is 228 mm (9.0 in) diameter and has a
facing material manufactured from APTEC T385.
The drive plate is sandwiched between the flywheel
and the pressure plate. The drive plate has a splined
hub which engages with the splines on the primary
shaft from the gearbox. The splined hub is located in
an inner plate which contains four compression
pre-damper springs. The inner plate is retained by
the springs which can compress in both directions to
cushion engine vibration at tickover. The inner plate
is located on eight larger compression springs which
are located in a central plate. The hub is sandwiched
between the central plate and the friction damper.
The friction damper comprises friction washers
located between the hub and the central plate. The
friction washers reduce transmission noises and
vibrations.

CLUTCH
Hydraulic Operation
When the clutch pedal (9) is depressed, the piston
(8) is pushed into the master cylinder (7). The piston
pressurizes the fluid in the master cylinder forcing
the pressurized fluid along the hydraulic tube (10).
The pressure is felt at the piston (11) of the slave
cylinder (12) which moves under the hydraulic force
applied.
When the clutch pedal (9) is released, force from the
compressed fingers of the diaphragm (6), pushes
against the release fork (14) through the release
bearing. The release fork rotates which in turn
rotates the release lever (13).
The release lever pushes the piston (11) back into
the slave cylinder (12). This returns hydraulic fluid
back up the hydraulic tube (10) and into the master
cylinder (7).
Mechanism Operation
When the clutch pedal (9) is depressed, the
hydraulic pressure extends the piston (11) rod in the
slave cylinder (12). The extension of the piston rod
pushes the release lever (13) which transfers its
rotary movement to the release fork (14) to which it
is connected.
The release fork (14) pivots towards the engine and
converts its rotary movement into linear movement
of the release bearing (15). The release bearing
pushes on the fingers of the diaphragm (6) which
pivots about its fulcrum on the pressure plate
housing (5). As the diaphragm is deflected, its
pressure is removed from the pressure plate (16).
The three leaf springs (4) pull the pressure plate
away from the drive plate (17).
The removal of force from the pressure plate (16) on
the drive plate (17) reduces the friction between the
drive plate and the flywheel (3). The drive plate slips
against the flywheel and cannot transfer the drive
from the flywheel to the gearbox primary shaft (2).
6
DESCRIPTION AND OPERATION
When the clutch pedal is released, hydraulic
pressure is removed from the piston (11) in the slave
cylinder (12). The removal of the pressure allows the
release bearing (15) to be pushed back along the
gearbox primary shaft (2) by the fingers of the
diaphragm (6). The linear movement of the release
bearing is transferred to rotary movement of the
release fork (14) and the release lever (13) which
pushes the piston (11) into the slave cylinder (12).
The diaphragm (6) pivots on its fulcrum on the
pressure plate housing (5). This applies pressure to
the pressure plate (16) and overcomes the opposing
force applied by the leaf springs (4). The pressure
plate moves towards the flywheel (3) and applies
force to the drive plate (17).
The force applied to the drive plate (17) by the
pressure plate (16) increases the friction between
the drive plate and the flywheel (3). As the clutch
pedal (9) is released the friction increases and rotary
movement of the flywheel is transferred to the drive
plate, which in turn rotates the primary shaft (2) of
the gearbox.
When the pedal is released fully, the pressure
applied to the pressure plate (16) by the diaphragm
(6) forces the drive plate (17) onto the flywheel with
no slippage.

INTERMEDIATE REDUCTION DRIVE
Description
The Intermediate Reduction Drive, IRD, is fitted in
place of the conventional transfer box, and is
attached to the PG1 5 speed manual gearbox. The
combination of the two units provides drive to the
front and rear wheels. The IRD incorporates a
differential unit to control the proportion of drive
delivered to each front wheel, and in addition, it
operates in conjunction with the viscous coupling to
give the vehicle a self-sensing four wheel drive
system. The main casing, cover and pinion housing
are manufactured from cast aluminium.
The unit comprises of a main casing (2), a RH
housing (4), primary shaft (1), an intermediate shaft
(9), a differential unit (3), a laygear (5), hypoid gear
set (8), a rear output pinion (7) and a pinion housing
(6). An oil cooler, connected to the vehicle cooling
system, is fitted to prevent overheating of the IRD
lubricating fluid. The main casing also incorporates
the oil level/drain plugs and a breather outlet. There
are a total of seven taper roller bearings and one
parallel roller bearing supporting the primary shaft,
differential and output shaft assemblies.
Four seals, internal to the IRD, are used to prevent
mixing of the IRD and PG1 lubricating fluids.
DESCRIPTION AND OPERATION
1
TRANSFER BOX - ’IRD’
Operation
Oil Seals
Drive is transmitted from the gearbox to the IRD
primary shaft via the splined hub in the gearbox final
drive gear carrier. The drive is then transmitted from
the primary shaft gear, which is integral with the
primary shaft, to the layshaft which in turn drives the
differential for the front driveshafts, and via a bevel
drive gear and pinion to drive the rear axle. The
intermediate shaft passes through the centre of the
IRD primary shaft, and is the drive link between the
IRD differential, and the left-hand front driveshaft,
passing through the centre of the final drive carrier.
Externally, three oil seals prevent lubricating oil
escaping from the PG1 gearbox and the IRD unit.
The gearbox gear case houses the oil seal for the
left-hand front driveshaft, and the RH housing on the
IRD unit houses the oil seal (3) for the right-hand
front driveshaft, with the remaining oil seal (4)
located in the pinion housing of the IRD.
2
DESCRIPTION AND OPERATION
TRANSFER BOX - ’IRD’
There are also four internal oil seals in the IRD unit.
Two smaller diameter oil seals (1) are fitted internally
at each end of the primary shaft. These prevent oil
ingress along the intermediate shaft from the IRD
unit at the differential end. At the opposite end, the
seal prevents oil ingress from the gearbox along the
intermediate shaft. Two larger oil seals (2) are fitted
in the main casing where the IRD unit enters the
gearbox. The inner oil seal prevents oil ingress from
the IRD primary shaft entering into the area between
the two seals, and the outer oil seal prevents oil
ingress from the gearbox entering the same area.
On the underside of the main casing is a ’tell-tale’
drilling which is positioned between the inner and
outer primary shaft oil seals. Oil leakage from the
drilling will indicate either a faulty inner or outer
primary shaft oil seal. An ’O’ ring seal (5), fitted in a
machined groove, seals the IRD main casing to the
gearbox clutch housing.

DRIVE SHAFTS
DRIVE SHAFTS
All four drive shafts are of similar construction, the
main difference being in the lengths of the front and
rear drive shafts. The front drive shafts of early
vehicles are equipped with dynamic dampers. This
feature was deleted soon after first build. Front drive
shafts with and without dynamic dampers are
interchangeable between early and late vehicles.
Each drive shaft comprises a solid shaft with inner
and outer constant velocity joints. The inner joint is
of the tripode type with spherical bushing to reduce
sliding resistance; the shaft and inner joint are one
assembly. The outer joint is of the ball and socket
type, with a splined connection between the joint
and the shaft. The joints are packed with grease and
protected by gaiters.

DRIVE SHAFTS
PROPELLER SHAFTS AND VCU
Front propeller shaft
The front propeller shaft consists of a thin walled
tube with a coupling welded to the front end and a
conventional universal joint welded to the rear end.
The coupling bolts to the output flange of the IRD.
The universal joint is splined to the input shaft of the
VCU and secured by a bolt.
The coupling reduces vibration and accommodates
both angular movement (10 degrees maximum) and
axial movement (50 mm maximum) between the
propeller shaft and the IRD.
The universal joint incorporates serviceable, sealed
needle bearings.

DRIVE SHAFTS
VCU
The VCU automatically controls the transfer of drive
to the rear wheels by limiting the speed differential
between the front and rear propeller shafts . The unit
is supported in two propeller shaft bearings attached
to the floor cross member.
The VCU comprises a short cylinder which contains
an input shaft supported in a roller bearing race at
the front and a ball bearing race at the rear. Within
the cylinder, slotted discs are alternately attached to
the outer surface of the input shaft and the inner
surface of the cylinder. An output shaft is welded
onto the rear of the cylinder. A torsional damper is
bolted to a flange on the output shaft. The input
shaft is attached to the front propeller shaft and the
output shaft is attached to the rear propeller shaft.
The cylinder is a sealed unit filled with a silicon jelly.
The viscosity of the silicon jelly increases when
subjected to shear. When there is a speed
differential between the front and rear propeller
shafts , adjacent slotted discs in the VCU rotate in
relation to each other. The shearing action of the
rotating slotted discs increases the viscosity and
resistance to rotation of the silicon jelly.

DESCRIPTION AND OPERATION

7. Output shaft
DRIVE SHAFTS
The rear wheels are 0.8% under driven, so in most
conditions the vehicle is effectively front wheel drive,
with the rear wheels turning the rear propeller shaft
slightly faster than the IRD drives the front propeller
shaft. Since the speed differential is low, the
increase in viscosity of the silicon jelly is marginal
and there is little resistance to relative rotation of the
slotted discs.
When there is a significant speed differential
between the front and rear propeller shafts , e.g. the
front wheels lose traction or traversing rough terrain,
the viscosity and resistance to rotation of the silicon
jelly increases to a level that slows or stops relative
rotation of the slotted discs. With the front and rear
propeller shafts locked together, drive is thus
transferred from the IRD to the rear wheels.
Torsional damper
The torsional damper reduces vibration from the
propeller shafts . The damper consists of a rubber
membrane bonded between an outer ring and an
inner hub. Three bolts secure the inner hub to the
output shaft of the VCU.
Propeller shaft bearings
The two propeller shaft bearings are identical, and
each consist of a roller bearing race mounted into a
centre bearing housing. The bearing is
sealed-for-life and is a press fit on the input/output
shaft of the VCU. Bearing covers and flingers
prevent the ingress of moisture.
Rear propeller shaft
The rear propeller shaft consists of a thin walled
tube with a conventional universal joint welded to
each end. The rear universal joint is bolted to the
input flange of the final drive unit. The front universal
joint is splined to the output shaft of the viscous
coupling unit and secured by a bolt. Both universal
joints incorporate serviceable, sealed needle
bearings.

REAR DIFFERENTIAL
Description
The rear differential assembly serves to convert the
"angle of drive" through 90° and distribute drive, in
the desired proportions, to both rear wheels. The
type of rear differential fitted is an integral carrier
housing hypoid-gear in which the centre line of the
drive pinion is mounted below the centre line of the
ring gear. To minimise weight, the differential
housing is manufactured in aluminium alloy, and the
assembly is secured to the rear subframe by way of
three rubber bushed mountings.
The differential housing incorporates the drive pinion
gear shaft, which is supported by two opposed taper
roller bearings fitted to the pinion and cups
assembled into the carrier housing. The pinion
bearing pre-load is controlled by a collapsible spacer
and the torque of the pinion nut. The pinion position
is controlled by a selective shim located between the
inner pinion bearing cone and the pinion gear head.
The differential casing rear cover is manufactured
from pressed steel and is sealed to the casing with
RTV silicone sealant. The cover also incorporates
the oil filler plug. A breather is located in the top of
the differential casing to prevent pressurisation of
the casing.
The pinion oil seal, which is fitted in the differential
casing, is referred to as a "labyrinth" type seal and is
especially designed to prevent contaminant ingress.
The oil seal works in conjunction with a pressed
steel shield, referred to as a "flinger" which is
pressed on to the pinion drive flange. The two drive
shafts are also sealed by "labyrinth" type oil seals
fitted in the differential housing.
The differential oil level should be maintained to the
bottom of the filler plug. No oil changes are
specified.
The differential assembly is supported by two
opposed taper roller bearings. The bearing cups are
secured in the housing by removeable bearing caps.
Shims are located between the differential bearing
cones and differential case for controlling differential
bearing pre-load and ring gear to pinion gear
backlash.

STEERING
STEERING DESCRIPTION
The major steering components comprise a shock
absorbing telescopic steering column, a power
assisted steering rack, a power assisted steering
(PAS) pump, a fluid reservoir,a fluid cooler and fluid
pipes and hoses.
Steering Column
The steering column design incorporates an energy
absorbing mechanism to reduce driver impact loads
in the event of a collision. The column is mounted on
four captive studs which are located in an extension
to the bulkhead. The two lower mountings are fixed
and cannot move when loads are applied to them.
The upper mounting is designed to dis-engage or
deform when a load is applied, allowing the column
to collapse in the event of an accident. The steering
column is adjustable to allow the steering wheel to
be moved vertically up or down to the desired
position. The steering column must be replaced as a
complete assembly if necessary.
The upper column tube is telescopic and can slide
over the lower column tube. The upper column tube
provides for the location of the steering lock and
ignition switch and also the steering switch gear and
a rotary coupler. The rotary coupler provides the
electrical connection for the steering wheel mounted
airbag and horn switches.
The central shaft comprises of two parts and is
located in bearings in the upper and lower column
tubes. The upper shaft is located inside the lower
shaft. Mating cross holes in each shaft are
connected by nylon injection moulded shear pins.
The upper shaft is splined to accept the steering
wheel. The lower shaft is connected by a universal
joint to the intermediate shaft. A second universal
joint on the opposite end of the intermediate shaft is
attached to a split adaptor. The adaptor is splined
and mates with the splined rotor shaft from the
steering rack.
The upper mounting bracket has two open slots with
a PTFE coated, metal ’U’ clip over each slot. Two
soft metal ’curling’ plates are riveted to the mounting
bracket and cover the slots.
The mounting studs pass through the ’U’ clips and
the curling plates. The lock nuts that retain the upper
mountings to the bulkhead extension are tightened
to between 12 and 15 Nm. This torque figure
controls the breakout load required to move the
upper mounting brackets from the studs in the
bulkhead extension and is critical to the crash
performance of the column.
Energy absorbtion is achieved by the following
mechansim:
When an axial load is applied to the steering
column, the mounting bracket deforms or slides out
of the ’U’ clips and the curling plates deform. The ’U’
clips remain captive on the studs When the column
mounting moves, the upper column tube slides on
the lower column tube and allows approximately 63
mm (2.5 in.) maximum of axial movement. The nylon
injection moulded shear pins holding the upper and
lower shafts together shear, allowing the central
shaft to telescope the same amount as the column
tubes.
If, in the event of a collision where the steering rack
itself moves, two universal joints in the column allow
the intermediate shaft to articulate, minimizing
movement of the column towards the driver. If
movement continues after articulation of the
intermediate shaft, the injection moulded shear pins,
retaining the two halves of the central shaft, shear
causing the shafts to ’telescope’ together reducing
further column intrusion.
The steering wheel comprises a cast centre and wire
frame onto which the soft polyurethane foam is
moulded. A horn switch is located at each side of the
wheel. Both switches are connected by wires to the
rotary coupler connector.
DESCRIPTION AND OPERATION
3
STEERING
Protection to the drivers face and upper torso is
provided by an SRS airbag located in the centre of
the steering wheel under a plastic cover.
The column adjuster is located on the left hand side
of the steering column and allows the steering
column and wheel to be tilted up or down over a
range of approximately 3.5° or 30 mm of vertical
movement of the steering wheel. The column
adjuster comprises a bolt which passes through
each side of the column upper mounting bracket.
The column adjustment lever is attached to a two
start left hand threaded nut which screws onto the
bolt.

STEERING
When the lever is lowered the nut is slackened and
allows the column to be moved up or down to the
desired position. Lifting the lever upwards tightens
the nut, clamping the mounting bracket to the
column, retaining the steering column in the selected
position.
NOTE: The nut tightening torque is 10.5
Nm which gives the correct ’feel’ to the
lever operation.
The steering lock houses the ignition switch, ignition
illumination light ring, key lock barrel and the alarm
passive coil
The steering lock is attached to the upper column
with a clamp plate and two shear bolts. The bolts are
tightened to a torque which shears off the heads of
the bolts preventing easy removal of the steering
lock.
The steering lock operates by a bolt, which emerges
when the ignition key is turned to position ’O’ and
the ignition key removed. The bolt engages in a lock
collar located on the upper shaft in the upper column
tube. The lock collar is attached to the upper shaft
by a ’wave form’ interference ring. The lock collar is
allowed to slip on the upper shaft if a torque of
200 Nm or higher is applied. This prevents damage
to the steering lock, yet still prevents the vehicle
from being driven.
The steering lock is designed to be resistant to slide
hammer, shock retraction and scaffold pole attack
and cannot be damaged by torque transmitted
through the column.

STEERING
Steering Rack
The steering rack is unique in its design having the
track rods mounted at a central location on the rack.
The track rods are very long and combined with the
optimized steering geometry provide low levels of
’bump steer’.
The steering rack is mounted in the engine
compartment on the lower part of the bulkhead. The
rack is retained with two bolts through cast lugs near
the valve unit and two bolts which secure a clamp
over the opposite end of the rack. The lower bolt
through the cast lug is fitted with a large washer. The
steering rack is handed for left and right hand drive
vehicles.
The rack requires 3.16 turns from lock to lock and
the rack and pinion has an overall ratio of 19.6:1.
A valve unit is fitted to one end of the steering rack
and connects, via a splined rotor shaft, to the
adaptor of the steering column. The valve unit has
four hydraulic connections; a pressure feed from the
PAS pump, a return line and two pressure lines to
the annulus and full area of the hydraulic cylinder.
A rotor shaft, which is located through the valve unit,
is connected to a pinion gear which drives on a rack
which, in turn is connected to the piston rod in the
hydraulic cylinder.
At a central position on the rack are two threaded
holes which allow for the attachment of the track
rods. Rubber bellows cover the movement area of
the rack.
Two hydraulic ports at each end of the hydraulic
cylinder of the rack are connected by metal pipes to
the valve unit. The ports supply hydraulic pressure
from the valve unit to the annulus and full area of the
cylinder. The cylinder end of the piston rod is fitted
with a piston which houses a piston seal.
8
DESCRIPTION AND OPERATION
The track rods are fitted with rubber bushes which
are hard enough to give positive feel to the steering
but at the same time reduce unwanted feedback
through the track rod. Each track rod is fitted with a
track rod end. The track rod end is a ball joint which
locates on an extended bracket on the suspension
strut and secured with a lock nut. A turnbuckle is
screwed into the track rod and the track rod end and
allows for the adjustment of the steering alignment.
The track rods are located on a bushed slider which
locates on the rack. Two spacers are located
between the slider and the track rods. Two flanged
bolts secure the track rods to the rack.
Valve Unit
The valve unit is an integral part of the steering rack.
The principal function of the valve unit is to provide
maximum power assistance (ie; when parking) with
minimum effort required to turn the steering wheel.
The cast outer casing of the valve unit has four ports
which provide the connections for pressure feed
from the pump, return to the fluid reservoir and
pressure feed from the valve unit to the annulus and
full area of the cylinder. A non return valve and seal
is fitted in the pressure feed port from the PAS
pump.
The valve unit comprises an outer sleeve, rotor,
torsion bar and a pinion shaft. The valve unit is
coaxial with the pinion shaft which is connected to
the steering column via the input shaft. The valve
unit components are located in a housing which is
screwed to a mating casting on the steering rack
main body and secured with screws.
STEERING
The outer sleeve is located in the main bore of the
valve unit. Three annular grooves are machined on
its outer diameter. PTFE rings are located between
the grooves and seal against the bore of the valve
unit. Holes are drilled radially in each annular groove
through the wall of the sleeve. The bore of the outer
sleeve is machined to accept the input shaft. Six
equally spaced slots are machined in the bore of the
sleeve. The ends of the slots are closed and do not
continue to the ends of the outer sleeve. The radial
holes in the outer sleeve are drilled into each slot.
The input shaft is splined at its outer end and has a
cross hole for location of the torsion bar. The inner
end has splines which are a loose fit in
corresponding splines in the pinion shaft. The width
of the splines allows the torsion bar to twist several
degrees before the splines contact one another. The
splined coupling between the input shaft and the
pinion shaft ensures that if the power steering fails,
the steering can be operated manually without
overstressing the torsion bar. The central portion of
the input shaft has equally spaced longitudinal slots
machined in its circumference. The slots are
arranged alternately around the input shaft.

PAS Pump
A vane type pump supplies hydraulic pressure to the
steering rack valve unit. The pump is driven by a
Poly Vee belt from the crankshaft pulley. A self
adjusting tensioner is fitted to maintain the correct
belt tension.
The pump comprises a body and cover which house
the internal components of the pump. A pressure
relief valve assembly is installed transversely in the
body. The relief valve also operates as a flow control
valve. The pressure relief valve limits the maximum
pressure to between 89 and 95 bar (1290 and
1377 lbf/in2). The flow control orifice limits the
maximum flow to between 5.0 and 6.0 l/min (1.32
and 1.58 gal/min). The body and cover are retained
by four socket capscrews and sealed with a
moulded seal plate.
A shaft runs longitudinally through the pump. One
end of the shaft has a hub which accepts the drive
pulley. On ’L’ Series engines, the opposite end has a
’D’ shaped drive coupling which mates with the drive
for the water pump. On K Series engines, the
opposite end is closed by an extended cover. The
shaft runs on a ball bearing located in the body. Oil
seals at each end of the shaft prevent the leakage of
hydraulic fluid.
An oval cam is located in the body. Ten roller vanes
are housed in a carrier and rotate within the cam.
The carrier is mounted in the centre of the shaft and
receives positive drive from the shaft via a drive pin.
The carrier is seated against an end plate which is
located in the cover. The front of the carrier is
covered by a port plate which is located against a
seal plate in the body. The port plate controls the
fluid flow into and out of the roller vanes during their
cycle.

mesh which is moulded into the frame of the filter.
The filter removes particulate matter from the fluid
before it is drawn into the supply connection and is
non-serviceable.
The primary function of the fluid reservoir is to hold a
surplus of hydraulic fluid in the system to allow for
expansion and contraction of the fluid due to
temperature variations. The fluid level ensures that
the supply connection is covered with fluid at all
operational attitudes. Any air that may be present in
the hydraulic system will be exhausted from the fluid
at the reservoir.

1. Inlet port
2. Roller vane chamber
3. Discharge port
As the pump rotates, centrifugal force causes the
roller vanes to move outwards in the slots in the
carrier and contact the cam. As the carrier rotates,
the cam form causes the space between the rollers
to increase. The increasing volume between the
roller vanes, causes a depression which draws fluid
into the space between the rollers.
As the carrier continues to rotate, the inlet port is
closed to the roller vanes which have drawn the
fluid, trapping the fluid between the rollers. As the
carrier rotates further, the cam form causes the
space between the roller vanes to decrease,
pressurizing the fluid between the rollers.

DESCRIPTION AND OPERATION

6. Roller vanes
Further rotation of the carrier, subjects the roller
vanes to the discharge port and fluid is displaced
under pressure from between the roller vanes into
the discharge port. The space between each pair of
rollers is subjected to this cycle twice for every
revolution of the pump.

Pump
Inlet port
The pump is a positive displacement type pump and
potential output from the pump increases
proportionally to engine speed. A flow control valve
is fitted to the pump to maintain a constant
predetermined flow regardless of engine speed. The
flow control valve controls the flow of fluid and
increases or decreases the flow discharged from the
pump to compensate for engine speed variations.
With the engine at idle the discharge flow from the
pump is low and the full flow from the pump is
delivered to the valve unit. As engine speed
increases, the flow delivered by the pump increases
proportionally.
5. Flow control valve
6. Relief valve passage
7. Recirculation passage
A pressure difference is created between each side
of the metering orifice as the engine speed
increases, the higher pressure being felt at the pump
side of the metering orifice. This higher pressure is
also felt at the top of the flow control valve via the
recirculation passage. The lower pressure on the
discharge side of the metering orifice is felt at the
bottom of the flow control valve via the relief valve
passage.
When the pressure at the top of the flow control
valve exceeds the rating of the flow control valve
spring, the valve begins to open against the spring
pressure and the lower pressure at the discharge
side of the metering orifice. Fluid is allowed to flow
through the recirculation passage and recirculate
through the pump.
As engine speed increases, the flow control valve is
pushed down further, increasing the flow through the
recirculation passage.

Pump Pressure Relief Valve Operation
A = Fluid intake
B = Fluid discharge
1. Inlet port
2. Discharge port
A pressure relief valve is located in the centre of the
flow control valve. If the pressure on the discharge
side of the metering orifice reaches a predetermined
level, a spring loaded ball in the centre of the valve
will lift from its seat and allow pressurized fluid to
recirculate within the pump.
The pressure relief valve will operate if the discharge
from the pump is restricted, steering held at full lock.
If the discharge from the pump is completely
blocked, all fluid discharged will be recirculated
through the pump.
As no fresh oil is drawn into the pump from the
reservoir, the fluid temperature inside the pump will
increase quickly. Consequentially, periods of
operation of full lock should be kept to minimum to
avoid overheating the pump and the fluid within it.

STEERING
Steering Rack Operation
Right steering
Rotary movement of the steering wheel is
transferred via the steering column to the valve unit
which is mounted on the steering rack. The rotary
movement of the steering is converted into linear
movement of the steering rack through the rack and
pinion. With the engine running and the PAS pump
operating, pressurized fluid is available to the
steering rack for power assistance.
Clockwise rotation of the steering wheel in turn
rotates the rotor and the torsion bar in the same
direction. The slots in the rotor move out of their
neutral alignment and block the return flow of fluid to
the reservoir. Fluid pressure from the pump now
flows from the pump into the newly aligned slots in
the rotor and outer sleeve. The pressure is directed
by the alignment of the slots into the right hand side
of the hydraulic cylinder where the pressure
increases. The left hand side of the hydraulic
cylinder is opened to return and allows fluid
displaced from the left hand side of the piston to flow
to the reservoir. The pressure difference on the left
and right hand sides of the piston in the cylinder
gives the power assistance to turn the steering.
Neutral Position
With no movement of the steering wheel being
applied, fluid flows from the pump to the valve unit.
The slots in the outer sleeve and the rotor are so
aligned that the fluid pressure flows across the valve
unit. Some pressure is applied to the feed and return
ports which in turn is felt at either side of the piston
in the hydraulic cylinder. With the forces equal on
each side of the cylinder, the steering remains in the
neutral position. The majority of the fluid delivered
from the pump is returned from the valve unit, and
via the fluid cooler, back to the reservoir. With the
majority of the fluid being returned to the reservoir,
the pressure available at each side of the piston is
very low.
Left steering
Anti-clockwise rotation of the steering wheel in turn
rotates the rotor and the torsion bar in the same
direction. The slots in the rotor move out of their
neutral alignment and block the return flow of fluid to
the reservoir. Fluid pressure from the pump now
flows from the pump into the newly aligned slots in
the rotor and outer sleeve. The pressure is directed
by the alignment of the slots into the left hand side of
the hydraulic cylinder where the pressure increases.
The right hand side of the hydraulic cylinder is
opened to return and allows fluid displaced from the
right hand side of the piston to flow to the reservoir.
The pressure difference on the left and right hand
sides of the piston in the cylinder gives the power
assistance to turn the steering.
Progressive Assistance
Progressive power assistance is dependant on the
amount of road wheel resistance opposing the
turning of the front wheels. When the steering wheel
is turned to the left or right, the rotary movement is
transferred through the steering column to the rotor
shaft which rotates the same amount as the steering
wheel. The rotary movement is also transferred from
the rotor to the torsion bar. If the road wheel
resistance is high, (when parking), the torsion bar
will twist. The twisting of the torsion bar means that
the rotary movement of the pinion and the sleeve is
slightly less than that of the rotor.
The twisting of the torsion bar moves the slots in the
rotor and the torsion bar out of alignment, resulting
in the gaps between both sets of slots becoming
larger. The greater the resistance of the road wheels
to the steering rotary movement, the greater the
misalignment of the slots in the rotor and torsion bar.
As the misalignment becomes greater, the fluid
pressure passing to the applicable side of the
hydraulic cylinder increases.
When the road wheel resistance reduces or less
effort is applied to the turning of the steering wheel,
the reduced torque applied to the rotor allows the
torsion bar to unwind. This reduces the
misalignment between the slots in the rotor and the
torsion bar, reducing the fluid pressure applied to the
applicable side of the hydraulic cylinder.

STEERING
Hydraulic Circuit Operation
When the engine is started, the pump draws fluid
from the reservoir down the low pressure suction
line. The fluid passes through the pump and
emerges as pressurised fluid at the discharge port
where it passes through a hose to a valve unit. If no
steering effort is applied, the pressure is applied
equally to each side of the piston in the hydraulic
cylinder. The remainder of the flow is returned from
the valve unit to the reservoir via the fluid cooler.
If steering effort is applied in either direction, the fluid
pressure is directed to the applicable side of the
piston in the hydraulic cylinder, providing power
assistance to reduce the steering effort required.
The fluid displaced by the movement of the piston in
the cylinder is returned through the valve unit to the
reservoir via the fluid cooler.
The fluid cooler reduces the fluid temperature which
prolongs the life of the hoses and seals in the
system.

FRONT SUSPENSION
FRONT SUSPENSION DESCRIPTION
The front suspension comprises two MacPherson
strut dampers with coil springs, two lower
suspension arms and an anti-roll bar. A front
subframe is bolted to the body and provides
mounting points for the lower suspension arms.
Each damper has a steering arm which provides for
the attachment of the track rods from the power
steering rack.
The suspension is designed to allow longitudinal
movement of the wheel, which allows the wheel to
move rearwards and upwards in response to surface
undulations. The longitudinal movement allows the
springs and dampers time to react to surface
changes which improves ride quality.
MacPherson Struts
The left and right hand dampers are handed but
otherwise similar in construction. The front dampers
are similar to the rear dampers but have slightly
different damping characteristics. The damping
characteristics of the front dampers also differs
between petrol and diesel variants. The spring rates
also differ between the front and rear suspension,
petrol and diesel variants and also between vehicles
with and without air conditioning.
The damper has a forged steering arm which
provides for the attachment of the track rod via a ball
joint and the anti-roll bar link. The damper body is
fabricated from thick walled tubing and has welded
brackets for attachment of the swivel hub. A smaller
welded bracket provides for the attachment of the
brake hose to the caliper and the ABS sensor cable
(if fitted).
Each damper is fitted with a coil spring. The coil
spring locates in a fabricated seat and is retained in
a partially compressed condition on the damper by a
spring seat, top mount and nut. The top mount is
fitted with three studs which locate in mating holes in
the inner wing turret. The top mount is fitted with a
bearing which allows the damper rod to pivot when
the steering is turned.
4
DESCRIPTION AND OPERATION
On vehicles fitted with air conditioning, the front
springs are approximately 5 mm longer. This
maintains the correct ride height with respect to the
additional weight of the air conditioning equipment.
A spring aid and a bump cup are fitted to the damper
to prevent shock loads when the damper is fully
compressed. A dust cover prevents the ingress of
dirt and water to maintain the integrity of the
chromium plated damper rod.
The damper functions by restricting the flow of a
hydraulic fluid through internal galleries within the
damper. A chromium plated damper rod moves
axially within the damper. As the rod moves, its
movement is limited by the flow of fluid through the
galleries thus providing damping of undulations in
the terrain. The damper rod is sealed at its exit point
from the damper body to maintain fluid within the
unit and to prevent the ingress of dirt and moisture.
The seal also acts as a wiper to keep the rod outer
diameter clean.
Anti Roll Bar
The anti-roll bar is mounted to the upper face of the
front subframe in two places. Rubber bushes fitted
to the anti-roll bar are held in position by two clamps
retained with bolts. The outer ends of the anti-roll bar
are each connected to a link, which in turn is
attached to the damper.
The links have a ball joint at each end. The other
end is attached to the anti-roll bar and secured with
a nut. The link transmits suspension movements
directly to the anti-roll bar. The design of the links
reduces the steer effects commonly found in this
type of suspension.
FRONT SUSPENSION
Lower Suspension Arms
The lower suspension arms are fabricated from steel
and each arm is handed. The arms are attached at
two pivot points. The forward end of the arm
contains a bush and is attached to lugs on the front
subframe with a bolt. A spigot on the rear mounting
of the arm engages with a bush and housing
assembly and is retained with a snubber washer and
a nut. A ball joint is located on the outer part of the
arm and is connected to the swivel hub and secured
with a nut.
The two pivot bushes have a significant role in
vehicle handling. The bushes control the longitudinal
movement of the wheel due to braking, acceleration
or surface undulations.
Front bush
The front bush is located at a specified angle to the
axis of rotation of the lower suspension arm. The
front bush is deflected radially and axially as the
wheel moves rearwards. The angle of the bush
ensures that the wheel moves directly rearward
reducing the effects of longitudinal steer to a
minimum.
Rear Bush
The rear bush is mounted on the axis of rotation of
the lower suspension arm. In the radial direction the
bush is relatively soft in its construction. In the axial
direction, the bush is very soft for the first 2 mm of
movement. Snubbing areas to the front and rear of
the bush provides a progressive increase in the
hardness of the bush as the deflection of the wheel
increases. The rear bush controls the amount that
the wheel can move forward or rearward.

REAR SUSPENSION
REAR SUSPENSION DESCRIPTION
The rear suspension comprises two MacPherson
strut dampers with coil springs and two sets of three
links (known as "trapezoidal links"). A rear subframe
is bolted to the body and provides the mounting
points for the fixed and adjustable links. The third
link is known as the trailing link and is attached from
the hub carrier to the body.
The suspension is designed to allow longitudinal
movement of the wheel, which allows the wheel to
move rearwards and upwards in response to surface
undulations. The longitudinal movement allows the
springs and dampers time to react to surface
changes and improves ride quality.
A spring aid and a bump cup are fitted to the damper
to prevent shock loads when the damper is fully
compressed. A dust cover prevents the ingress of
dirt and water to maintain the integrity of the
chromium plated damper rod.
The damper functions by restricting the flow of a
hydraulic fluid through internal galleries within the
damper. A chromium plated damper rod moves
laterally within the damper. As the rod moves, its
movement is limited by the flow of fluid through the
galleries thus providing damping of undulations in
the terrain. The damper rod is sealed at its exit point
from the damper body to maintain fluid within the
unit and to prevent the ingress of dirt and moisture.
The seal also acts as a wiper to keep the rod outer
diameter clean.
MacPherson Struts
Trapezoidal Links
The left and right hand dampers are handed but
otherwise similar in construction. The rear dampers
are similar to the front dampers but have slightly
different damping characteristics.
The damper body is fabricated from thick walled
tubing and has welded brackets for attachment of
the hub carrier. Two smaller welded brackets
provide for the attachment of the brake hose to the
brake pipe and the ABS sensor cable (if fitted).
Each damper is fitted with a coil spring. The coil
spring locates in a fabricated seat and is retained in
a compressed condition on the damper by a top
mount and nut. The top mount is fitted with three
studs which locate in mating holes in the inner wing
turret and retained with three self locking nuts. A
bump plate is fitted which accommodates a spring
aid. The bump plate is sealed against the inner wing
turret to prevent the ingress of moisture into the
interior load space.
The spring rates differ between the front and rear
suspension.

DESCRIPTION AND OPERATION
Three links make up the trapezoidal linkage. The
fixed transverse link is fabricated and is not
adjustable. The adjustable transverse link comprises
a tube, threaded at each end. A threaded fitting is
screwed into each end of the tube and locked with
lock nuts to a prescribed distance between centres.
Each fitting has a pressed bush installed. The
trailing link is fabricated and is not adjustable.
The fixed transverse link is bushed at each end and
is located in the forward mounting of the rear
subframe and the forward attachment on the hub.
The adjustable transverse link is also bushed at
each end and is located in the rearward mounting of
the rear subframe and the rearward attachment on
the hub. The fixed transverse link and the adjustable
transverse link are attached to the rear subframe
with individual bolts and nuts and are attached to the
hub with a single bolt and nut with a washer at each
end.
REAR SUSPENSION
The trailing link is bushed at one end. The bushed
end is located in a separate bracket which is bolted
to the body. The link is secured with a bolt which
screws through the bracket into a captive nut in the
body rail. The opposite end is forked and locates
over a bushed lug on the hub and secured with a
bolt and nut.
The fixed transverse links, the adjustable transverse
links and the trailing link have a significant role in the
vehicle handling. The bushes in each link control the
longitudinal movement of the wheel due to braking,
acceleration or surface undulations.
The adjustable transverse link allows for the toe-in of
the wheel to be adjusted if necessary. The fixed
transverse link is slightly shorter than the adjustable
link which promotes a small amount of toe-in during
cornering. This also minimizes the effects of bump
steer. The bush attaching the fixed transverse link to
the rear subframe has a very soft initial movement
rate which becomes progressively harder as the rate
of deflection increases. The three remaining bushes
in the fixed transverse and the adjustable
transvserse links are of hard construction which give
precise handling and minimizes transient steer
effects. The soft bush allows for small amounts of
toe-in during cornering.

BRAKES
Vehicle braking is provided by disc brakes on the
front wheels and drum brakes on the rear wheels.
The foot brakes are operated by a diagonally split,
dual circuit hydraulic system with vacuum servo
power assistance. A cable operated handbrake
operates on the two rear brakes.
The hydraulic system has two variants, a non
anti-lock braking system and an ABS variant. The
ABS variant features 4-wheel electronic traction
control and hill descent functions as well as anti-lock
braking.
FRONT BRAKES
The front brakes each comprise a hub mounted,
single piston caliper assembly and a solid disc. The
inboard side of the disc is protected by a mudshield.
When hydraulic pressure is supplied to the caliper,
the piston extends and forces the inner pad against
the disc. The caliper body reacts and slides on the
guide pins to bring the outer pad into contact with
the disc.
REAR BRAKES
The rear brakes each comprise a hub mounted
backplate and drum containing leading and trailing
brake shoes. An adjuster rod is incorporated to
automatically adjust the brake shoes to compensate
for wear of the brake linings. Adjustment occurs
during operation of the foot brake.
When hydraulic pressure is supplied to the wheel
cylinder, the cylinder extends and forces the brake
shoes against the drum.

HYDRAULIC SYSTEM
The hydraulic system operates the brakes in
response to brake pedal movement and, on ABS
variants, operation of the ABS modulator.
To reduce operating noise on vehicles with ABS,
sleeving is installed on some of the brake pipes in
the engine compartment and the pipes are located in
sprung pipe clips.
For normal brake operation, brake pedal movement
is assisted by the brake servo assembly and
transmitted to the master cylinder assembly. The
master cylinder assembly converts brake pedal
movement to hydraulic pressure. Primary and
secondary brake pipe circuits supply the hydraulic
pressure to the brakes: the primary circuit supplies
the front left and rear right brakes; the secondary
circuit supplies the front right and rear left brakes. A
Pressure Conscious Reducing Valve (PCRV)
regulates the pressure to the rear brakes to give
front/rear differential braking.
A red, brake warning lamp in the instrument pack
illuminates if the fluid level in the hydraulic system
falls to an unsafe level.
Vacuum for the brake servo assembly is obtained
from the engine inlet manifold (petrol models) or a
vacuum pump (diesel models) through a vacuum
line and non return valve.

Brake servo assembly
The brake servo assembly provides power
assistance to reduce the pedal load when braking.
The assembly is attached to the front of the pedal
box and comprises a circular housing containing a
diaphragm, push rods, valve and filter. A push rod at
the rear of the housing is connected to the brake
pedal. The vacuum line is connected to a port in the
front face of the housing.
With the brake pedal released and the engine
running, vacuum pressure is present on both sides
of the diaphragm. When the brake pedal is pressed,
the rear push rod moves forward and opens the
valve to allow atmospheric pressure through the
filter into the pedal side of the diaphragm. The
pressure differential acting on the diaphragm
increases the pressure being applied by the brake
pedal, which is transmitted to the master cylinder via
the forward push rod.
If the servo fails, the hydraulic system will still
function but will require greater pedal effort due to
the lack of vacuum assistance.

Vacuum pump (diesel models only)
As the diesel engine air inlet system does not
produce sufficient depression to operate the brake
servo assembly, an engine driven vacuum pump is
installed. The vacuum pump is integrated with the
engine alternator and driven by the accessory drive
belt. The pump is a rotary vane type, lubricated and
cooled by engine oil supplied through a pipe
connected to the centre front of the engine block and
returned through a pipe connected to the centre
front of the oil sump. Air extracted from the brake
servo assembly is vented into the oil sump with
returning lubricating oil.
NOTE: Normally, only a small volume of
air is drawn from the brake servo
assembly. However, a leak in the brake
servo assembly or vacuum pipe may cause
excessive crankcase pressure.

BRAKES
Master cylinder assembly
The master cylinder assembly produces hydraulic
pressure to operate the brakes when the brake
pedal is pressed. The assembly is attached to the
front of the brake servo assembly, and comprises a
cylinder containing two pistons in tandem. The rear
piston produces pressure for the primary circuit and
the front piston produces pressure for the secondary
circuit.
Installed on top of the cylinder is a brake fluid
reservoir. The reservoir is internally divided to
provide an independent supply of fluid to each brake
circuit, and so prevent a single fluid leak from
disabling both primary and secondary brake circuits.
Should a failure occur in one circuit, the remaining
circuit will still operate effectively, although brake
pedal travel and vehicle braking distances will
increase. If the fluid level in the reservoir is too low,
the brake fluid level switch in the reservoir filler cap
connects an earth to the instrument pack and
illuminates the brake warning lamp.
Non ABS master cylinder
When the brake pedal is pressed, the front push rod
in the brake servo assembly pushes the primary
piston along the cylinder bore. This produces
pressure in the primary pressure chamber which, in
conjunction with the primary spring, overcomes the
secondary spring and, simultaneously, moves the
secondary piston along the cylinder bore. The initial
movement of the pistons takes the recuperating
seals past the cut-off holes in the cylinder wall.
Further movement of the pistons then pressurizes
the fluid in the primary and secondary pressure
chambers, and thus the brake circuits. The fluid in
the chambers behind the pistons is unaffected by
movement of the pistons and can flow unrestricted
through the feed holes between the chambers and
the reservoir.
10
DESCRIPTION AND OPERATION
When the brake pedal is released, the primary and
secondary springs push the pistons back down the
bore of the cylinder. This creates a depression in the
pressure chambers, which causes the recuperation
seals to momentarily collapse and allows fluid from
the chambers behind the pistons to flow into the
pressure chambers. Fluid from the reservoir flows
through the feed holes to compensate for the loss of
fluid from the chambers behind the pistons. The final
return movement of the pistons exposes the cut-off
holes and allows excess fluid in the pressure
chambers to flow into the reservoir.
ABS master cylinder
When the brake pedal is pressed, the front push rod
in the brake servo assembly pushes the primary
piston along the cylinder bore. This produces
pressure in the primary pressure chamber which, in
conjunction with the primary spring, overcomes the
secondary spring and simultaneously moves the
secondary piston along the cylinder bore. The initial
movement of the pistons, away from the piston
stops, closes the primary and secondary centre
valves. Further movement of the pistons then
pressurizes the fluid in the primary and secondary
pressure chambers, and thus the brake circuits. The
fluid in the chambers, behind the pistons, is
unaffected by movement of the pistons and can flow
unrestricted through the feed holes between the
chambers and the reservoir.
When the brake pedal is released, the primary and
secondary springs push the pistons back down the
bore of the cylinder. As the pistons contact the
piston stops, the primary and secondary centre
valves open, which allows fluid to circulate
unrestricted between the two hydraulic circuits and
the reservoir, through the centre valves, the
chambers behind the pistons and the feed holes.

PCRV
The PCRV is a twin valve unit that reduces the
hydraulic pressure supplied to the rear brakes to
maintain vehicle stability under braking. A mounting
bracket attaches the PCRV to the RH inner wing.
The PCRV comprises two cast housings, one
connected to the primary brake circuit and one
connected to the secondary brake circuit. The two
housings are bolted together and connected by an
internal passageway. The passageway in each
housing contains a piston sleeve, poppet valve and
associated seals and springs. One housing
incorporates a vent from the internal passageway,
which is sealed by a rubber vent plug.
On ABS variants, only the rear brake pipes are
connected to the PCRV. On non ABS variants, both
the front and the rear brake pipes are connected to
the PCRV, but the flow to the front brake pipes is
unregulated.
When the brakes are applied, pressurized brake
fluid from the inlet ports passes through the piston
sleeves and the open poppet valves to the rear
brake outlet ports. On non ABS variants, pressurized
brake fluid also passes directly from the inlet ports to
the front brake outlet ports. Hydraulic pressure, on
the outer ends of the piston sleeves, moves the
piston sleeves against spring pressure towards the
centre of the PCRV. When the piston sleeves
contact the poppet valves, the rear brake outlet ports
are isolated from the inlet ports.
As the pressure from the master cylinder increases,
the poppet valves remain closed until, at
approximately 25 bar (367.5 lbf.in2), hydraulic
pressure overcomes poppet valve spring pressure to
allow a restricted flow through to the rear brake
outlet ports. The restriction causes a pressure drop
across the poppet valves, to give a front : rear brake
pressure differential of 10 : 3.

BRAKES
On non ABS variants, in order to balance the
hydraulic pressure to the rear brake outlets, the two
piston sleeves act in opposition to each other at
either end of a common spring. Any difference in
pressure at the two inlet ports causes the position of
the piston sleeves to be biased towards the lower
pressure circuit. This causes an increase in the
pressure drop across the poppet valve of the circuit
with the higher pressure. The subsequent pressure
at the outlet port is then approximately the same as
the pressure at the outlet port of the low pressure
circuit.
In the event of failure of an internal seal, fluid will
enter the centre chamber of the PCRV and, when
the brake pedal is applied, will cause the vent plug
to rupture and allow brake fluid to escape.
When the brakes are released, the piston sleeves
are moved outwards by spring pressure. This opens
the poppet valves, releasing hydraulic pressure from
the rear brakes and allowing brake fluid to flow back
towards the master cylinder.

ABS
The ABS is a full time, four channel system that
gives individual speed control of all four wheels to
provide the vehicle with anti-lock braking (ABS),
Electronic Traction Control (ETC) and Hill Descent
Control (HDC) functions. In addition to the
components of the non ABS brake system, vehicles
with ABS have an ABS modulator, four ABS sensors
and an ABS Electronic Control Unit (ECU).
ABS modulator
The ABS modulator controls the supply of hydraulic
pressure to the brakes in response to inputs from
the ABS ECU. The modulator is attached by three
mounting bushes to a bracket on the RH inner wing,
and connected to the primary and secondary
hydraulic circuits downstream of the master cylinder
assembly. Three electrical connectors link the ABS
modulator to the vehicle wiring.
Internal passages in the ABS modulator, separated
into primary and secondary circuits, connect to the
various components that control the supply of
hydraulic pressure to the brakes. Shuttle valves and
check valves control the flow through the internal
circuits. Shuttle valve switches, connected in series
to the ABS ECU, provide a brakes on/off signal. A
damper chamber and restrictor are included in each
circuit to refine system operation. Inlet and outlet
solenoid valves control the flow to the individual
brakes. An expansion chamber is connected to each
circuit to absorb pressure. A return pump is
connected to both circuits to provide a pressure
source.
The ABS modulator has three operating modes:
• Normal braking mode: When the brake pedal is
pressed, pressurized fluid from the master
cylinder assembly moves the shuttle valves to
open lines A’ and close the shuttle valve
switches. Pressurized fluid then flows through
the open inlet solenoid valves to operate the
brakes. The shuttle valve switches supply a
brakes on signal to the ABS ECU.
• ABS braking mode: When in the normal braking
mode, if the ABS ECU detects that a wheel is
about to lock, it energizes the inlet and outlet
solenoid valves of the related brake and starts
the return pump. The inlet solenoid valve closes
to isolate the brake from pressurized fluid; the
outlet solenoid valve opens to release pressure
from the brake into the expansion chamber and
the return pump circuit. The brake releases and
the wheel begins to accelerate. The ABS ECU
then operates the inlet and outlet valves to
control the supply of hydraulic pressure to the
brake and apply the maximum braking effort (for
the available traction) without locking the wheel.
• Active braking mode: When ETC or HDC are
enabled, and the ABS ECU determines that
active braking is required, it starts the return
pump. Hydraulic fluid, drawn from the reservoirs
through the master cylinder, shuttle valves and
lines B’, is pressurized by the return pump and
supplied to lines A’. The ABS ECU then
operates the inlet and outlet solenoid valves to
control the supply of hydraulic pressure to the
individual brakes and slow the wheel(s).
ABS sensors
The ABS sensors supply the ABS ECU with a speed
signal from each wheel. An inductive sensor is
installed in a bush in each wheel hub, sensing off a
60 tooth exciter ring. A fly-lead connects each
sensor to the vehicle wiring. The exciter rings are
fitted to the outer diameter of the constant velocity
joint on each drive shaft and shielded by the hub
centre boss.

ABS operation
The ABS ECU controls the operation of the ABS
modulator to provide the ABS, ETC and HDC
functions. It also operates warning lamps in the
instrument pack to provide the driver with status
information on each function. The ABS ECU is
attached to a bracket below the RH front seat,
beneath a protective cover. Incorporated into the
ABS ECU are integrated circuits and software for
system control and diagnostics. Three electrical
connectors interface the unit with the vehicle wiring.
The purpose of ABS is to prevent vehicle wheels
locking during brake application, thus maintaining
vehicle steerability and stability. This allows the
vehicle to be steered while the brakes are applied,
even under emergency conditions, and to avoid
obstacles where there is sufficient space to redirect
the vehicle.
The warning lamps consist of:
• An amber ABS graphic.
• An amber TC graphic.
• Two inclined vehicle graphics for HDC, one
amber (fault), which includes an exclamation
mark, and one green (information).
The warning lamp bulbs are serviceable items that
can be renewed from the rear of the instrument
pack.
When the ignition is switched on, the ABS ECU
performs a bulb check of the warning lamps as part
of the power up procedure. The ABS warning lamp
is extinguished briefly, after 1.3 to 2 seconds, then
remains illuminated until vehicle speed exceeds 4.4
mph (7 kph). The ETC and HDC warning lamps are
extinguished after 4 to 5 seconds. If a fault warning
lamp remains illuminated after the lamp check, a
fault has been detected and repair action is required.
The ABS ECU continually calculates vehicle speed
using the inputs from all four ABS sensors. Vehicle
speed is used as a reference against which
individual wheel speeds are monitored for
unacceptable acceleration or deceleration. Vehicle
speed is also output to the instrument pack for the
speedometer.
WARNING: ABS is an aid to retaining
steering control and stability while
braking. ABS cannot defy the natural laws
of physics acting on the vehicle. ABS will not
prevent accidents resulting from excessive
cornering speeds, following another vehicle too
closely or aquaplaning, i.e. where a layer of
water prevents adequate contact between tyre
and road surface. The additional control
provided by ABS must never be exploited in a
dangerous or reckless manner which could
jeopardise the safety of driver or other road
users. The fitting of ABS does not imply that the
vehicle will always stop in a shorter stopping
distance.
NOTE: During normal braking the feel of
the brake pedal on vehicles equipped with
ABS will be the same as that on non ABS
vehicles. During anti-lock braking operation the
driver will experience feedback in the form of a
pulsating brake pedal and solenoid/pump motor
noise from the ABS modulator.
The anti-lock braking function is automatically
enabled whenever the ABS modulator is in the
normal braking mode.
While the anti-lock braking function is enabled, if the
ABS ECU detects a wheel decelerating faster than
the average, indicating it is about to lock, it operates
the ABS modulator in the ABS braking mode for the
affected wheel.

ETC operation
ETC uses brake intervention to prevent wheel spin.
The ETC function operates on all four wheels and is
automatically enabled at speeds up to 31.3. mph (50
kph) provided the brakes are off.
While the ETC function is enabled, if the ABS ECU
detects a wheel accelerating faster than the
average, indicating loss of traction, it operates the
ABS modulator in the active braking mode for the
affected wheel. The ABS ECU also illuminates the
ETC warning lamp, for a minimum of 2 seconds or
for the duration that ETC is active. If the brake pedal
is pressed while ETC is active, the ABS ECU reverts
to ABS mode.
HDC operation
HDC uses brake intervention to provide a controlled
descent ability in off road conditions when engine
braking is insufficient to maintain a comfortable
speed. The HDC function operates with the vehicle
travelling forwards or backwards and is selected
on/off by a switch on the gear lever. When selected,
HDC is enabled at speeds of 3.6 mph (5.7 kph) and
above provided the vehicle is in first or reverse gear
with the clutch engaged. In off road conditions this
allows the driver to leave HDC selected and to
control the vehicle’s descent speed, down to the
system’s minimum target speed, using only the
accelerator pedal.
Minimum target speeds with the throttle closed are 6
mph (9.6 kph) in first gear and 4 mph (6.5 kph) in
reverse gear. The first gear target speed is
decreased to 4.4 mph (7 kph) if rough terrain or
sharp bends (detected from ABS sensor inputs) are
encountered while already travelling at the minimum
target speed. Minimum target speeds are increased
at cold idle to prevent conflict between the brakes
and the engine caused by HDC trying to impose a
lower vehicle speed than is normal for the increased
engine speeds at cold idle. Minimum target speeds
at cold idle are 7.5 mph (12 kph) in first gear and 4.4
mph (7 kph) in reverse gear.
During active braking, the brakes are operated in
axle pairs on one or both axles. The braking effort is
distributed between the front and rear axles as
necessary to maintain vehicle stability. Distribution
of the braking effort is dependant on direction of
travel and braking effort being applied. To prevent
wheel lock, anti-lock braking is also enabled during
active braking.
The ABS ECU incorporates a fade out strategy that,
if a fault occurs or HDC is deselected during active
braking, provides a safe transition from active
braking to brakes off. The fade out strategy
increases the target speed at a low constant
acceleration rate, independent of actual throttle
position. If active braking is in operation, this causes
the braking effort to be gradually reduced and then
discontinued. The HDC information warning lamp
flashes while fade out is in progress.
When HDC is selected, the HDC information
warning lamp illuminates permanently if HDC is
enabled or flashes if HDC is not enabled (i.e. the
vehicle is not in first or reverse gear, or the clutch is
disengaged). When HDC is enabled, the ABS ECU
calculates a target speed from the throttle position
element of the engine ECU input, and compares this
with actual speed. If the actual speed is higher than
the target speed, the ABS ECU operates the ABS
modulator in the active braking mode to achieve and
then maintain the target speed. While the braking
force is being applied, the ABS ECU also energizes
the ABS brake lamp relay to put the brake lamps on.
Active braking is discontinued while vehicle speed is
below the target speed or if the foot brakes are
applied. Applying the foot brakes during active
braking may result in a pulse through the brake
pedal, which is normal.
DESCRIPTION AND OPERATION
23
BRAKES
If the clutch is disengaged during active braking, the
HDC information warning lamp flashes after a delay
of 3 seconds. After 60 seconds, if the clutch is still
disengaged, the HDC fault warning lamp flashes and
active braking operation fades out.
To prevent the brakes overheating, the ABS ECU
monitors the amount of active braking employed
and, from this, calculates brake temperature. If the
ABS ECU determines brake temperature has
exceeded a preset limit, it extinguishes the HDC
information warning lamp and flashes the HDC fault
warning lamp to indicate that HDC should be
deselected. If active braking continues and the ABS
ECU determines that brake temperature has
increased a further 50 °C, it fades out active braking
and disables HDC. After fade out, the HDC fault
warning lamp continues to flash, while HDC is
selected, until the ABS ECU calculates brake
temperature to be at an acceptable level. This
calculation continues even if the ignition is turned
off, so turning the ignition off and back on will not
reduce the disabled time. When the ABS ECU
calculates the brake temperature to be acceptable, it
extinguishes the HDC fault warning lamp and
illuminates the HDC information warning lamp to
indicate HDC is available again. The disabled time is
dependant on vehicle speed; typical times at
constant vehicle speeds are as follows:

DESCRIPTION AND OPERATION

Diagnostics
While the ignition is on, the diagnostics function of
the ABS ECU monitors the system for faults. In
addition, the return pump is tested by pulsing it
briefly immediately after the engine starts provided
vehicle speed exceeded 4.4 mph (7 kph) during the
previous ignition cycle. If a fault is detected at any
time, the ABS ECU stores a related fault code in
memory and illuminates the appropriate warning
lamps in the instrument pack. If a fault exists in a
warning lamp circuit, the lamp will not illuminate
during the lamp check at ignition on, but, provided
there are no other faults, the related function will
otherwise be fully operational.
After rectification of an ABS sensor fault, the ABS
and ETC functions are disabled, and their warning
lamps remain illuminated, until vehicle speed
exceeds 9.4 mph (15 kph) (to allow additional
checks to be performed).
Fault retrieval and diagnosis of the ABS ECU are
done using Testbook.

After detecting a fault, the ABS ECU selects an
appropriate default strategy which, where possible,
retains some operational capability. A shuttle valve
switch fault, sticking throttle and implausible gear
input are classified as permanent faults. If a
permanent fault is detected, the related warning
lamp illumination and default strategies are
automatically employed in subsequent ignition
cycles, even if the fault is intermittent, until the fault
has been rectified and cleared from memory. If a
non permanent fault is detected, the related warning
lamp illumination and default strategies will only be
employed in subsequent ignition cycles if the fault is
still present.

BRAKES
HANDBRAKE
The handbrake operates on both rear brakes via two
handbrake cables, a cable equaliser and an
intermediate rod on the handbrake lever.
As the handbrake lever is applied, movement is
transmitted by the intermediate rod and the cable
equaliser to the two handbrake cables. Each
handbrake cable pulls on a lever on the trailing
brake shoe. The lever pivots against the brake’s
adjuster rod, which forces the brake shoes apart and
brings the brake linings into contact with the drum.
The cables are adjusted by the handbrake adjust nut
that locates the cable equaliser on the intermediate
rod.
A warning switch, on the base of the handbrake
lever, operates the brake warning lamp in the
instrument pack. When the handbrake is applied and
the ignition is on, the warning switch connects an
earth to the instrument pack and illuminates the
brake warning lamp. In some markets, the central
control unit performs a bulb check of the brake
warning lamp each time the ignition is switched on.

SYSTEM
Seat belts are provided as the primary restraint for
all occupants. The supplementary restraint system
provides additional protection for front seat
occupants.
SEAT BELTS
An inertia reel, three point seat belt is installed at
each seat position. The inertia reels are of the
Emergency Locking Retractor (ELR) type which
incorporate a liftshaft locking system with webbing
sensor and car sensor activating mechanisms. The
webbing sensor activates the locking system if the
webbing is subjected to a sharp pull. The car sensor
activates the locking system if the vehicle is
subjected to sudden deceleration or a severe tilt
angle.
Front seat belts
The inertia reel of each front seat belt is attached to
the related B/C post, behind the finishers. The
webbing runs from the inertia reel, through a height
adjuster, to an anchor point either at the base of the
B/C post (five door models), or on a bar attached to
the inner sill (three door models).
The buckle assembly for each belt, consisting of a
buckle attached to a flexible stalk and an integrated
pretensioner, is secured to the inboard side of the
related front seat frame.

SUPPLEMENTARY RESTRAINT SYSTEM (SRS)
Precautions
When carrying an airbag module, hold it by the
cover, with the cover uppermost and the base away
from your body. Do not wrap your arms around the
module.
Making the system safe
Before working on, or in the area of, the SRS, make
the system safe as follows:
1. Remove the key from ignition switch.
2. Disconnect both battery leads, earth lead first.
3. Wait 10 minutes to allow the SRS back-up power
to fully discharge.
Do not try to disassemble an airbag module or seat
belt pretensioner. They have no serviceable parts
and, once deployed, cannot be repaired or reused.
Do not expose an airbag module or seat belt
pretensioner to heat exceeding 85°C (185°F) or
allow it to be contaminated with oil, grease,
detergent or water.
General
Carefully inspect SRS parts before installation. Do
not install a part that shows signs of being dropped
or improperly handled, such as dents, cracks or
deformation.
The airbag ECU is a shock sensitive device and
must be handled with extreme care. Because the
crash sensor is incorporated inside the airbag ECU,
it is imperative that the bolts securing the airbag
ECU and its bracket are tightened to their correct
torque.
Do not install used SRS parts from another vehicle.
When repairing a SRS, use only new parts.
Always use new fixings when replacing SRS parts.
Do not use a multimeter or other general test
equipment to check SRS parts or connectors.
After completing work, check that the electrical
connectors are installed correctly.
Handling and storage
WARNING: If the airbag is improperly
stored face down, accidental deployment
could propel the unit with enough force to
cause serious injury.
CAUTION: Improper handling or storage
can internally damage the airbag module,
making it inoperative. If you suspect the
airbag module has been damaged, install a new
unit and refer to the Workshop Manual for
Deployment/Disposal Procedures.
Do not allow anything to rest on an airbag module.
4
DESCRIPTION AND OPERATION
For temporary storage of an airbag module or seat
belt pretensioner during service, place in a
designated storage area or, if no designated storage
area is available, in the loadspace of the vehicle;
always lock the vehicle and inform the workshop
supervisor.
Airbag modules and seat belt pretensioners are
classed as explosive articles. For overnight and
longer term storage, they must be stored in an
approved, secure steel cabinet which has been
registered by the local authority.
RESTRAINT SYSTEMS
SRS wiring
Never attempt to modify, splice or repair SRS wiring.
Never install electronic equipment such as a mobile
telephone, two way radio or in car entertainment
system in such a way that it interferes electrically
with the SRS wiring.
Always ensure SRS wiring is routed correctly. Be
careful to avoid trapping or pinching the SRS wiring.
Ensure the are no possible chafing points.
Always use specified earth fixings tightened to the
correct torque. Poor earthing can cause intermittent
problems that are difficult to diagnose.
Ensure all SRS wiring connectors are mated
correctly and securely fastened. Do not leave the
connectors hanging loose.
Warning labels
Warning labels are displayed on SRS parts and
prominent places on the vehicle to indicate:
• The need for caution when working in close
proximity to SRS parts.
• That, if a passenger airbag module is installed,
rearward facing child seats are prohibited on
front passenger seats.
• The publication where suitable reference and
advice can be found (usually the Workshop
Manual or Owner’s Handbook).

DESCRIPTION AND OPERATION
4. Driver’s airbag module

RESTRAINT SYSTEMS
The SRS is an electronically controlled, single point
sensing system. The system comprises an airbag
Electronic Control Unit (ECU), a driver’s airbag
module, a passenger’s airbag module (optional), two
seat belt pretensioners and a warning lamp.
Interconnecting wiring for the system is contained in
yellow sleeving and integrated into the vehicle
harnesses. A rotary coupler connects the vehicle
harness to the driver’ airbag module. On vehicles
with a passenger’s airbag module, a link lead
connects the module to the vehicle harness. An ISO
9141 K line (bi-directional) serial communication link
connects the airbag ECU to the vehicle’s diagnostic
socket.
The system is operational only while the ignition is
on. With the ignition on, any frontal collision is
detected by the airbag ECU. If the impact is above
the preset severity, the ECU sends out simultaneous
fire signals to the airbag modules and the seat belt
pretensioners. The airbag modules then deploy
protective airbags in front of the driver and front seat
passenger, and the seat belt pretensioners retract to
tighten the front seat belts. Collision detection to full
deployment of the airbags and pretensioners takes
approximately 45 milliseconds.
WARNING: All the SRS parts, including the
wiring harness, link lead (where fitted) and
rotary coupler, must be renewed after the
airbags and pretensioners have deployed.

RESTRAINT SYSTEMS
Airbag ECU
Power back-up
The airbag ECU controls the operation of the system
and also contains the collision detection sensors.
The airbag ECU is attached to a bracket on the
transmission tunnel, directly below the heater. A
vehicle earth output connects to one of the fixings. A
30 pin connector provides the airbag ECU
connection with the vehicle harness.
The airbag ECU incorporates capacitors to ensure
the system will function if the external power supply
is disconnected during a collision:
• A hardware capacitor provides power for 200
milliseconds to enable system operation and
collision recording.
• Individual capacitors for each fire signal output
provide power for 150 milliseconds.
Incorporated into the airbag ECU is a mechanical
safing sensor, an electronic single point sensor and
integrated circuits for control and diagnostics. The
mechanical safing sensor is a normally open switch
that closes at the preset deceleration limit. The
single point sensor is an accelerometer that
produces an output proportional to the vehicle’s
deceleration .
The capacitors are kept charged while the ignition is
on by a dc-dc voltage converter incorporated into the
airbag ECU. It can take up to 10 minutes from the
ignition being switched off for the energy stored in
the capacitors to fully dissipate and make the
system inert.

RESTRAINT SYSTEMS
Operation
Diagnostics
When the ignition is switched on, the airbag ECU
performs a bulb check of the SRS warning lamp as
part of the power up procedure. The lamp should be
extinguished after approximately 5 seconds,
indicating that the system is fully operational. If the
lamp remains illuminated, a fault has been detected
and repair action is required.
While the ignition is on the diagnostic function of the
airbag ECU monitors the SRS for faults. If a fault is
detected, the airbag ECU stores a related fault code
in memory and switches the earth output to
illuminate the SRS warning lamp. With a supply
voltage range fault, the warning lamp is illuminated
only for the duration of the fault. With all other faults,
including intermittent faults, the warning lamp is
illuminated for the remainder of the drive cycle. At
the next ignition on, if the fault is still present the
warning lamp remains illuminated after the lamp
check; if the fault does not recur, the warning lamp
extinguishes but the fault code remains stored in
memory. An intermittent fault will be cleared from
memory if 40 drive cycles are completed without its
recurrence.
While the ignition is on, data from the single point
sensor is continuously monitored by the airbag ECU.
If the data from the single point sensor indicates
vehicle deceleration is at or above the preset limit,
and the mechanical safing sensor is closed, the
ECU interprets this as a collision that requires
deployment of the airbags and retraction of the seat
belt pretensioners. It then activates transistors to
send fire signals to the airbag modules and the seat
belt pretensioners. Simultaneously, the airbag ECU
records in memory the following information:
• The error code of the last permanent fault (if any)
detected before the collision.
• Internal program information about the collision
as seen by the airbag ECU.
• The diagnostic status of the airbag and seat belt
pretensioner circuits before deployment.
• The voltage of each power backup capacitor
before deployment.
• Information on the airbag ECU internal program
status.
If external power is lost during the collision,
recording of the last three above items only occurs if
there is sufficient power in the backup capacitors
after outputting the fire signals.
After detecting a fault, the system may retain some
operational capability:
• If a fault is detected in an airbag or pretensioner
circuit, only that circuit is disabled; the other
airbag and pretensioner circuits remain
operational and their related components will still
be deployed in a collision.
• If an internal or power supply fault is detected,
the complete system will be disabled.
• If a fault exists in the SRS warning lamp circuit,
the lamp will not illuminate during the lamp check
at ignition on, but, provided there are no other
faults, the system will otherwise be fully
operational.
When deployment and collision event recording has
been completed, the airbag ECU enters crash
locked mode and illuminates the SRS warning lamp.
In crash locked mode the airbag ECU is
permanently disabled and must be replaced during
subsequent repair action. Crash locked mode
cannot be cleared using Testbook.
DESCRIPTION AND OPERATION
9
RESTRAINT SYSTEMS
Fault code retrieval and fault diagnosis of the SRS
can only be done using Testbook. Additional SRS
information that can be read using Testbook is the:
• Airbag ECU bar code.
• Evolution number of the hardware, software and
diagnostic protocol.
• Status of the crash locked mode.
• Vehicle identification number (VIN) data.
Diagnostic checks performed by the airbag ECU
include:
• Monitoring of the airbag and pretensioner circuits
for open/short circuits.
• Internal errors.
• Supply voltage (limits are 8.6 to 19.0 V at power
up, 6.0 to 19.0 V during drive cycle).
Airbag modules
During a frontal collision each airbag module
deploys a gas filled bag to form a protective cushion
between the front seat occupant and the steering
wheel or fascia/windshield. The driver’s airbag
module is attached to the centre of the steering
wheel. Where fitted, the passenger’s airbag module
is installed in the fascia, above the glovebox.
Each airbag module has a gas generator attached to
a folded airbag installed in a housing. The driver’s
airbag has an inflated volume of 45 litres; the
passenger’s airbag has an inflated volume of 120
litres. The gas generator of the driver’s airbag
module is filled with a nitrocellulose based material;
the gas generator of the passenger’s airbag module
is filled with a sodium azide based material.
The outlet of the gas generators incorporates a filter
screen to prevent solid combustion by-products
entering the airbag during deployment. An igniter
(squib) in each generator provides an ignition source
when triggered by a fire signal from the airbag ECU.
A 2 pin connector provides the interface between the
igniter and the vehicle wiring.
On the driver’s airbag module, the housing is closed
by a cover that forms the steering wheel centre pad;
split lines are formed in the inner surface of the
cover to direct the airbag through the required exit
point during deployment. On the passenger’s airbag
module, the housing is closed by a trim panel
profiled to match the fascia; a tethered deployment
door forms an integral part of the trim panel.
10
DESCRIPTION AND OPERATION
RESTRAINT SYSTEMS
Both airbag modules operate in the same way. On
receipt of a fire signal from the airbag ECU, the
igniter ignites the material in the gas generator. The
burning material rapidly produces a large amount of
nitrogen gas which passes through the filter screen
into the airbag, forcing the airbag to unfold. On the
driver airbag module, the unfolding airbag ruptures
the cover along the split lines; on the passenger
airbag module, the unfolding airbag breaks the
deployment door fixings to the module housing and
trim panel, and the deployment door lifts off the
fascia (but remains tethered to the module housing).
Once free of the housing the airbag inflates to its full
extent. Vents in the airbag prevent excess pressure
bursting the bag and, as soon as the material in the
gas generator is exhausted, allows the airbag to
instantly deflate.

Seat belt pretensioners
Seat belt pretensioner components
During a frontal collision the seat belt pretensioners
tighten the front seat belts to ensure the occupants
are securely held in their seats. A pretensioner is
integrated into the buckle assembly of each front
seat belt.
The two pretensioners are handed, but otherwise
identical. Each pretensioner has a tube containing
propellant and a piston. The piston is attached to a
steel cable, the opposite end of which is attached to
the seat belt buckle. An igniter (squib) in the base of
tube provides an ignition source when triggered by a
fire signal from the airbag ECU. A fly lead with a 2
pin connector links the igniter to the vehicle wiring.
On receipt of a fire signal from the airbag ECU, the
igniter ignites the propellant. The burning propellant
rapidly produces nitrogen gas that drives the piston
along the tube, pulling on the cable and drawing the
buckle towards the buckle assembly fixing point on
the seat.
SRS warning lamp
The SRS warning lamp provides system status
information for the driver. The lamp consists of a
bulb behind a red SRS graphic at the base of the
tachometer in the instrument pack. The bulb is a
serviceable item that can be renewed from the rear
of the instrument pack.

Rotary coupler
Rotary coupler components
The rotary coupler is installed on the steering
column to provide the interface between the fixed
wiring harness and the moveable driver airbag
module and horn buttons on the steering wheel.
A rotating link harness is encapsulated into a plastic
cassette comprising outer and inner housings with
integral connectors. Screws attach the outer housing
to the steering column switch assembly and the
inner housing is keyed to the steering wheel by its
connector. The inner housing can turn a maximum
of six revolutions in relation to the outer housing. For
maintenance purposes the outer housing
incorporates a position indicator wheel; a white tab
is visible on the wheel when the rotary coupler is
centralised. To prevent breaking the rotating link
harness, both the steering and the rotary coupler
must be centralised when removing and installing
the steering wheel.

BODY
CENTRAL DOOR LOCKING OPERATION
Tail Door
Driver and Passenger Door(s)
The tail door has no locking facility. When the
vehicle is locked, the CCU ignores operation of the
tail door handle. The door cannot be opened until
the CCU authorises electrical operation of the tail
door actuator which mechanically operates the tail
door latch.
The central door locking can be operated from either
the Central Door Locking (CDL) switch on the fascia,
the remote handset or the vehicle key in the driver’s
door lock.
All aspects of the central door locking system are
controlled by the Central Control Unit (CCU). The
driver and the passenger doors can be CDL locked
or superlocked.
Locking or unlocking the driver’s door using the
vehicle key, mechanically operates the driver’s door
latch. The mechanical operation simultaneously
operates a switch within the latch mechanism which
completes an earth path to the CCU. The CCU uses
the earth path as a signal to electrically operate the
remaining door lock motor(s) and lock or unlock the
passenger door(s). Each latch assembly contains
separate motors for CDL locking and superlocking.
The tail door handle contains a switch, which is
operated when the handle is pulled. The switch
completes an earth path to the CCU. The CCU uses
the earth path as a signal to electrically operate the
latch actuator to open the tail door latch.
The tail door latch assembly also contains a switch
which informs the CCU if the tail door is open. A
warning lamp on the instrument panel warns if an
open door condition is sensed by the CCU. The
switch also operates in conjunction with the vehicle
alarm system if the tail door is opened when the
alarm is armed.
Locking and unlocking using the CDL switch or the
remote handset is controlled electrically by the CCU.
Each outer door handle is connected to its
respective latch assembly via a linkage. Each
interior release handle is connected to the latch
assembly via a cable. A door sill button is connected
to each latch assembly and gives a visual indication
to the locked or unlocked condition of each door.
The button also allows each door to be individually
locked from inside the vehicle.
On 5 door models, both rear doors have a child door
lock facility. A small lever near the latch, when
selected, prevents the doors from being opened
from the interior of the vehicle. The doors can only
be opened using the outside door handles.
Each door latch assembly also contains a switch
which informs the CCU if a door is open. A warning
lamp on the instrument panel warns if an open door
condition is sensed by the CCU. The switch also
operates in conjunction with the vehicle alarm
system if a door is opened when the alarm is armed.

HEATING & VENTILATION
HEATING AND VENTILATION
The heating and ventilation system controls the
temperature and distribution of air supplied to the
vehicle interior. Air is drawn into a heater assembly
through a connector hose and an air inlet duct or, on
vehicles with air conditioning, the cooling unit. See
Air Conditioning, Description and Operation.
In the heater assembly, the air can be heated and
supplied as required to fascia and floor level outlets.
An electrical variable speed blower, and/or ram
effect when the vehicle is in forward motion, forces
the air
through the system. Temperature, distribution and
blower controls are installed on a panel on the
centre console.

between the fascia and the engine bulkhead.
The heater assembly consists of a two-piece plastic
casing containing a blower, resistor pack, heater
matrix and control flaps. Integral passages guide the
air through the casing from the inlet to the
distribution outlets. A wiring harness connects the
blower and resistor pack to the blower switch on the
control panel.

Resistor pack
The blower controls the volume of air being supplied
to the distribution outlets. The blower is installed in
the driver’s side of the casing and consists of an
open hub, centrifugal fan powered by an electric
motor. The open end of the fan surrounds the air
inlet, which is on the passenger’s side of the casing.
The blower switch and the resistor pack control the
operation of the blower, which can be selected to
run at one of four speeds.
The resistor pack supplies reduced voltages to the
blower motor for blower speeds 1, 2 and 3. For
blower speed 4, the resistor pack is bypassed and
battery voltage drives the motor at full speed. The
pack is installed in the RH side of the casing, in the
air outlet from the blower fan, so that any heat
generated is dissipated by the air flow.

HEATING & VENTILATION
Heater matrix
Temperature control
The heater matrix provides the heat source to warm
the air being supplied to the distribution outlets. It is
installed in the LH side of the casing behind a
protective cover. The matrix is a copper and brass,
two pass, fin and tube heat exchanger. Engine
coolant is supplied to the matrix through two brass
tubes that extend through the bulkhead into the
engine compartment. When the engine is running,
coolant is constantly circulated through the heater
matrix by the engine coolant pump.
Control flaps
Three control flaps are installed in the heater
assembly to control the temperature and distribution
of air. A blend flap controls the temperature and two
distribution flaps control the distribution.
Blend flap
The blend flap regulates the flow of air through the
heater matrix to control the temperature of the air
leaving the heater assembly. It consists of a hinged
flap between the cold air bypass and the heater
matrix. The flap hinge is connected to a lever
mechanism on the LH side of the casing. A control
cable is installed between the lever mechanism and
the temperature knob on the control panel to operate
the flap. Turning the temperature knob turns the flap
and varies the proportions of air going through the
cold air bypass and the heater. The proportions
vary, between full bypass no heat and no bypass full
heat, to correspond with the selection on the
temperature knob. When the flow is split between
the cold air bypass and the heater matrix, the two
flows are mixed downstream of the heater matrix to
produce an even air temperature at the individual
outlets.

fresh air flap is a hinged door that controls the flow
to the face level outlets. The hinge of each flap is
connected to a common lever mechanism on the RH
side of the casing. A control cable is installed
between the mechanism and the distribution knob
on the control panel to operate the flaps together.
Turning the distribution knob turns the flaps to direct
air through the corresponding outlets in the casing.

DISTRIBUTION
Air from the heater assembly is distributed around
the vehicle interior through fascia and floor level
outlets. Fascia outlets consist of fixed vents for the
windscreen and side windows, and adjustable vent
assemblies for face level air. Floor level outlets
consist of fixed vents for the front and rear footwells.
The front footwell vents are integrated into the
heater assembly. Two central vent assemblies for
face level air are connected directly onto the related
outlets of the heater assembly. Air for the rear
footwell, outer face level vent assemblies and
windscreen/side windows is distributed through
ducts.

DESCRIPTION AND OPERATION
HEATING & VENTILATION
Ducts
OPERATION
The rear footwell ducts extend along each side of
the transmission tunnel and vent into the rear
footwells from below the front seats. The outer face
level ducts attach to the underside of the fascia and
connect to the vent assembly at each end of the
fascia. The windscreen/side window ducts connect
to a duct integrated into the top of the fascia.
Air flow through the heater assembly is directed to
the outlets selected by the distribution control knob.
The temperature of the air from all except the face
level vents depends on the setting of the
temperature control knob. Hot air is available from
the face level vents only when the temperature
control knob is at the maximum heat setting. As the
temperature control knob is turned towards cold, the
temperature of the air from the face level vents
rapidly decreases to ambient (non A/C vehicles) or
evaporator outlet temperature (A/C vehicles). The
forward speed of the vehicle and the setting of the
blower control knob determines the volume of air
flowing through system.
Vent assemblies
The vent assemblies allow occupants to control the
flow and direction of face level air. Each vent
assembly incorporates a thumbwheel to regulate
flow and moveable vanes to control direction.
CONTROLS
Rotary knobs are installed on the centre console to
control air distribution, blower speed and air
temperature. The air distribution and temperature
knobs operate cables connected to the control flaps
in the heater assembly. The blower speed knob
operates a rotary switch in the blower’s electrical
circuit.

Where fitted, the air conditioning system supplies
cooled and dehumidified, fresh or recirculated air to
the interior of the vehicle. Air is cooled by drawing it
through the matrix of an evaporator. The air is then
ducted into the heater assembly, from where it is
distributed to the vehicle interior through the heating

AIR CONDITIONING
In the heater assembly, the temperature of the air
distributed to the vehicle interior can be adjusted by
passing a proportion, or all, of the cooled air through
the heater matrix. The volume of air being distributed
is controlled by the variable speed blower in the
heater assembly. For details of temperature control
and distribution. See Heating & Ventilation,
Description and Operation.
The air conditioning system comprises a refrigerant
system, a cooling unit and a control system.
REFRIGERANT SYSTEM
The refrigerant system transfers heat from the
vehicle interior to the outside atmosphere. The
system comprises a compressor, condenser,
receiver drier, thermostatic expansion valve and
evaporator, joined together by refrigerant lines. The
system is a sealed, closed loop, filled with a 725 ±
25 g charge weight of R134a refrigerant as the heat
transfer medium. ND oil 8 is added to the refrigerant
to lubricate the internal components of the
compressor (new compressors come pre filled with
ND8 oil 8).
To accomplish the transfer of heat, the refrigerant is
circulated around the system, where it passes
through two pressure/temperature regimes. In each
of the pressure/temperature regimes, the refrigerant
changes state, during which process maximum heat
absorbtion or release occurs. The low
pressure/temperature regime is from the
thermostatic expansion valve, through the
evaporator to the compressor; the refrigerant
decreases in pressure and temperature at the
thermostatic expansion valve, then changes state
from liquid to vapour in the evaporator, to absorb
heat. The high pressure/temperature regime is from
the compressor, through the condenser and receiver
drier to the thermostatic expansion valve; the
refrigerant increases in pressure and temperature as
it passes through the compressor, then releases
heat and changes state from vapour to liquid in the
condenser.
2
DESCRIPTION AND OPERATION
Compressor
The compressor circulates the refrigerant around the
system by compressing low pressure, low
temperature vapour from the evaporator and
discharging the resultant high pressure, high
temperature vapour to the condenser.
The compressor is attached to a mounting bracket at
the bottom right front of the engine. The drive pulley
and refrigerant line connections differ between petrol
and diesel engined models, but otherwise the
compressor is the same on both engine variants.
The compressor is a ten cylinder swash plate unit
with a fixed displacement of 177.7 cc/rev. The
auxiliary drive belt drives the compressor via a
pulley and an electrically actuated magnetic clutch.
Operation of the clutch is controlled by the engine
control module (ECM). To protect the refrigerant
system from unacceptably high pressure, a pressure
relief valve is installed in the outlet side of the
compressor. The pressure relief valve is set to
operate at 3430 kPa (497.5 lbf.in2) and vents excess
pressure into the engine compartment.

The condenser is a four pass heat exchanger, of fin
and tube brazed aluminium construction, with inlet
and outlet connections in the RH end tank.
Ambient air, passing through the condenser matrix
due to ram effect and/or the cooling and condenser
fans, absorbs heat from the refrigerant, which
changes state from a vapour to a liquid.

AIR CONDITIONING
Thermostatic expansion valve (TXV)
Evaporator
The thermostatic expansion valve meters the flow of
refrigerant into the evaporator to match the
refrigerant flow with the heat load of the air passing
through the evaporator matrix.
The evaporator absorbs heat from the exterior or
recirculated air being supplied to the heater
assembly.
The thermostatic expansion valve is attached to the
evaporator, in the cooling unit behind the
passenger’s side of the fascia. The valve is the
parallel charge type, consisting of an aluminium
housing containing inlet and outlet passages. A ball
and spring metering valve is installed in the inlet
passage and a temperature sensor is installed in the
outlet passage. The temperature sensor consists of
a push rod connected to a diaphragm. The bottom
end of the push rod acts on the ball of the metering
valve. Pressure on top of the diaphragm is controlled
by evaporator outlet temperature conducted through
the push rod. The bottom of the diaphragm senses
evaporator outlet pressure via internal passages.
Liquid refrigerant flows through the metering valve
into the evaporator. The restriction across the
metering valve reduces the pressure and
temperature of the refrigerant. The restriction also
changes the solid stream of refrigerant into a fine
spray, to improve the evaporation process. As the
refrigerant passes through the evaporator, it absorbs
heat from the air flowing through the evaporator
matrix. The increase in temperature causes the
refrigerant to vapourize and increase in pressure.
The temperature and pressure of the refrigerant
leaving the evaporator are sensed by the
temperature sensor, which regulates the metering
valve opening to control the volume of refrigerant
flowing through the evaporator. The warmer the air
flowing through the evaporator matrix, the more heat
available to evaporate refrigerant and thus the
greater the volume of refrigerant allowed through the
metering valve.
8
DESCRIPTION AND OPERATION
The fin and plate, brazed aluminium evaporator is
installed in the cooling unit behind the passenger’s
side of the fascia. Inlet and outlet connections on the
evaporator are attached to the thermostatic
expansion valve.
Low pressure, low temperature refrigerant changes
from liquid to vapour in the evaporator, absorbing
large quantities of heat as it changes state.
Refrigerant lines
To maintain similar flow velocities around the
system, the diameter of the refrigerant lines varies to
suit the two pressure/temperature regimes. The
larger diameters are installed in the low
pressure/temperature regime and the smaller
diameters are installed in the high
pressure/temperature regime. Low and high
pressure charging connections are incorporated into
the refrigerant lines for system servicing.

(ECM), the air conditioning control system operates
the condenser fan, cooling fan and compressor
clutch to control the operation of the refrigerant
system. The control system also operates the
recirculated air motor. The control system comprises
of two control switches, a trinary pressure switch, a
thermostat and a relay module.

AIR CONDITIONING
Control switches
Thermostat
The control switches consist of two latching push
switches installed in the centre console, an air
conditioning switch and a fresh/recirculated air
switch. Each switch contains an amber indicator
lamp which illuminates when air conditioning or
recirculated air is selected, as applicable.
The thermostat prevents ice formation on the
evaporator. The thermostat is installed in the cooling
unit, and consists of a pressure operated switch
connected to a capillary tube filled with a
temperature sensitive fluid. The end of the capillary
tube is located between the fins of the evaporator
core. If the temperature at the evaporator falls low
enough for ice to form on the fins, the fluid in the
capillary tube contracts sufficient to open the
contacts of the switch. The switch is calibrated to
open at -1°C and close at +1°C.
Trinary pressure switch
The trinary pressure switch senses refrigerant
pressure to protect the compressor, control the
refrigerant condensing pressure and limit the
maximum refrigerant pressure. Three separate
switches, low, normal and high, are contained in the
trinary pressure switch, which is installed in the top
of the receiver drier.
Since the compressor is lubricated by oil suspended
in the refrigerant, the low pressure switch prevents
operation of the compressor unless there is a
minimum refrigerant pressure, and thus refrigerant
charge, in the system. The switch is normally closed,
and opens if refrigerant pressure decreases to less
than the minimum.
The normal pressure switch provides fan speed
request signals for the ECM. Below a given pressure
the switch is open, producing a slow speed request
signal. When refrigerant pressure increases to a
value that indicates additional condensing is
required, the switch closes to produce a fast speed
request signal.
The high pressure switch is normally closed and
opens if refrigerant pressure exceeds the maximum
limit.
The three switches operate at the following
pressures:

DESCRIPTION AND OPERATION
Relay module
The relay module switches power to the compressor
clutch, cooling fan and condenser fan under the
control of the ECM. The relay module is installed in
the engine compartment, on the rear of the battery
tray, and consists of four relays in a plastic housing.
Two electrical connectors in the housing connect the
relay module to the vehicle wiring. The compressor
clutch is energized to engage and de-energized to
disengage. The motors of the two fans are switched
together, in series (6 volts nominal) for slow speed
and in parallel (12 volts nominal) for fast speed.
AIR CONDITIONING
OPERATION
Refrigerant pressure control
Air conditioning operates only while the engine is
running and the blower in the heater assembly is on
(any speed). Fresh or recirculated air can be
selected with or without the air conditioning being
on, provided the ignition is on.
Under most conditions, refrigerant pressure is kept
within limits by the ECM switching the fans between
slow and fast speeds in response to the fan speed
request signal from the trinary pressure switch.
However, if refrigerant pressure goes outside the
upper or lower limit, the trinary pressure switch
removes the air conditioning request signal from the
ECM. The ECM then switches air conditioning off
(the indicator lamp in the air conditioning switch
remains on). When the pressure returns within limits,
the ECM automatically switches air conditioning on
again.
Air conditioning
When the air conditioning switch is selected on, the
indicator lamp in the switch illuminates and an air
conditioning request signal is input to the ECM. The
air conditioning request signal consists of an earth
through the blower switch, air conditioning switch,
thermostat and trinary pressure switch (low and high
switches in series). The ECM is also in receipt of a
fan speed request input from the trinary pressure
switch (normal switch). The fan speed request signal
consists of an open circuit (slow speed) or earth
(fast speed).
On receipt of the air conditioning request signal, the
ECM switches air conditioning on by signalling the
relay module to engage the compressor clutch and
run the cooling and condenser fans at the
appropriate speed. The engine drives the
compressor to circulate the refrigerant. The blower
draws fresh or recirculated air through the
evaporator. As the air flows through the evaporator,
moisture condenses out from the relatively warm air
onto the cold evaporator. The dehumidified air is
then fed into the heater assembly, from where it is
distributed to the vehicle interior.
Evaporator anti-icing
If the temperature of the air leaving the evaporator
decreases to -1°C, the thermostat removes the air
conditioning request signal from the ECM. The ECM
then switches air conditioning off (the indicator lamp
in the air conditioning switch remains on). When the
temperature of the air leaving the evaporator
increases to +1°C, the thermostat reinstates the air
conditioning request signal, and the ECM switches
air conditioning on again.
When the air conditioning switch is selected off, or if
the blower is selected off, the indicator lamp in the
air conditioning switch extinguishes and the air
conditioning request signal is removed from the
ECM. The ECM then switches air conditioning off by
signalling the relay module to disengage the
compressor clutch and stop the cooling and
condenser fans.
DESCRIPTION AND OPERATION
13
AIR CONDITIONING
Engine overheat protection
If engine coolant temperature reaches 117.5°C
(diesel models) or 118°C (petrol models), the ECM
switches the air conditioning off to reduce the load
on the engine (the indicator lamp in the air
conditioning switch remains on). When engine
coolant decreases to 115°C (diesel models) or
114°C (petrol models), the ECM switches air
conditioning on again.
Fresh/Recirculated air selection
When recirculated air is selected, the amber
indicator lamp in the switch illuminates and the
recirculated air motor turns the control flap to open
the recirculated air inlet and close the fresh air inlet.
When fresh air is selected, the amber indicator lamp
extinguishes and the recirculated air motor turns the
control flap to open the fresh air inlet and close the
recirculated air inlet.

be renewed immediately before
evacuating and recharging the system.
4. Operate the refrigerant evacuation system
according to the manufacturers instructions.
NOTE: If the vacuum reading is below 700
mm/Hg after 15 minutes, suspect a leak in
the system. Partially recharge the system
and check for leaks using an electronic leak
tester.
CAUTION: The system must be evacuated
immediately before recharging
commences. Delay between evacuation
and recharging is not permitted.
5. Operate the refrigerant recharging system
according to the manufacturers instructions.
Amount of refrigerant required to charge
system is 725 ± 25 g.
6. If the full charge has not been accepted by the
system, start the engine and run it at 1500
rev/min for a minimum of 2 minutes.
7. Switch on the air conditioning system, open the
car windows, set the temperature control to
cold and switch the blower to maximum speed.
8. Consult the Refrigerant Station Manual for the
correct procedure to complete the charge.
9. Carry out the air conditioning system
performance test.
10. Switch off air conditioning and wait for
pressures to equalize, before disconnecting
charging hoses from vehicle.
EVACUATION AND RECHARGING
WARNING: Servicing must be carried out

The temperatures and pressures may be slightly
increased for high humidity conditions. The
refrigerant pressure will dictate whether the fans
operate in series or parallel, which will itself cause
the temperatures and pressures to fluctuate. Fans
could operate as follows:
• Condenser and cooling fan both running at half
speed (series).
• Condenser and cooling fan both running at full
speed (parallel).
• Fans switching from series to parallel.

WIPERS & WASHERS
WINDSCREEN WIPERS DESCRIPTION
The windscreen wiper functions are controlled from
the wash/wipe stalk located on the right hand side of
the steering column. The wash/wipe stalk is a
multi-function switch which controls the windscreen
wiper, intermittent and washer operation. The
Central Control Unit (CCU) is responsible for the
operation of the intermittent wipe facility and the park
facility when the wipers are turned off.
Two front windscreen wipers are operated by a
single electric motor. The motor and a link assembly
are located below the plenum grill at the base of the
windscreen.
The link assembly is handed for left and right hand
drive vehicles. All other wiper components remain
common to both versions. The component
descriptions and operation are the same for both left
and right hand drive.
The parallel coupled link assembly comprises a
curved galvanized tube which has a cast wheel box
pushed into each end of the tube and crimped for
retention. A galvanized link arm is attached to a
lever at the base of each wheel box.
Each link is attached by a spherical bearing which is
permanently attached to the lever and the link. The
opposite end of each link also has a spherical
bearing, which are both attached to a spigot which in
turn is attached to a lever. The lever has a splined
bore and mates with a splined shaft from the motor.
A spring washer and nut secure the lever to the
shaft.
Each wheel box comprises a cast housing, through
which a splined shaft is located on bearings. The
outer end of each shaft has splines which provide
positive location for the wiper arms. The link
assembly is a sealed unit and is not serviceable.
The motor is attached to the link assembly with three
bolts. The motor can operate at two speeds for fast
and slow wiper operation. The motor is a DC motor
with permanent magnets. The central shaft of the
motor is fitted with a worm drive which in turn rotates
a gear connected to the splined drive shaft.

DESCRIPTION AND OPERATION
The two speed operation is achieved by three
brushes in the motor. One brush is the common
earth. The slow speed is initiated by a brush
positioned 180° to the common brush. The fast
speed is initiated by a brush positioned at
approximately 45° to the common brush. The fast
speed operates by the brushes transferring direct
current to a smaller portion of the armature coils,
which causes the armature to rotate faster, but with
a lower torque than the slow speed.
A wiper arm is located on the splined shaft of each
wheel box and secured with a nut. The wiper arm
attachment to the splined shaft has a pivot to which
the remainder of the arm is attached. The two parts
of the arm are connected by a spring which controls
the pressure of the blade on the screen to a
predetermined amount.
Each wiper blade is attached to its wiper arm with a
clip that allows the blade to pivot. Each wiper blade
comprises a number of levers and yokes to which
the rubber wiper is fitted. The levers and yokes
ensure that the pressure applied by the arm spring is
distributed evenly along the full length of the blade.
The rubber wiper is held in the yokes by a pair of
stainless steel strips, which also distribute the spring
pressure evenly. The driver’s side wiper blade is
fitted with an airfoil, which presses the wiper blade
onto the windscreen at high speed. This prevents
the wiper blade from lifting off the screen and
maintains the wiping performance.
WIPERS & WASHERS
REAR SCREEN WIPER DESCRIPTION
The rear screen wiper functions are controlled from
a push button switch located to the right of the
instrument pack or by the selection of reverse gear
when the front wipers are operating. The Central
Control Unit (CCU) is responsible for monitoring and
controlling the operations of the rear screen wiper
motor.
The rear screen wiper has three modes of operation;
programmed mode, intermittent and slow.
• Programmed mode operates when the rear
screen wiper is selected by operation of the
wash/wipe switch. The rear screen washer and
the wiper operate when the switch is depressed.
When the switch is released, the washers stop
and the wiper continues for five cycles before
stopping.
• Intermittent operates when the rear screen wiper
is selected using the latching push button switch.
The wiper operates for three complete cycles,
then the CCU operates the wiper intermittently
every five seconds until the wiper is selected off.
• Slow mode operates when reverse gear is
selected and the front wipers are on. The rear
wiper operates until reverse gear is disengaged
or the front wipers are switched off.
The rear screen wiper is operated by a single
electric motor which indirectly drives, via an
eccentric drive mechanism, a splined shaft to which
the wiper arm is attached.
The motor is a single speed dc motor with
permanent magnets. The motor shaft is fitted with a
worm drive which rotates a gear wheel. The gear
wheel has an offset spigot to which an eccentric cam
is fitted which can rotate through 180° in each
direction. A coil spring is located around the cam
and operates as a simple friction clutch to enable the
cam to be rotated when the motor is driven in
reverse. A connecting link is attached to the cam
and drives two gears located in a link. The
connecting link converts the rotary motion of the
gear wheel into linear movement of the link. The
linear movement is converted back into rotary
movement of the splined shaft which moves the
wiper arm in an arc in two directions across the rear
screen.
The wiper motor has the ability to park the wiper arm
off the rear screen when the wiper is selected off.
When the motor is operating to wipe the rear screen,
the motor shaft is rotating in a clockwise direction.
When the rear screen wiper is selected off, the CCU
allows the wiper arm to reach the vertical position on
the screen. A micro switch actuated by a slip ring on
the underside of the gear wheel, signals that the
wiper arm has reached this position. The CCU then
reverses the polarity of the supply to the motor
which causes the motor shaft to rotate in an
anti-clockwise direction.
When the motor changes direction, the eccentric
cam is rotated through 180° which effectively
lengthens the linear movement of the connecting
link. This causes the wiper arm to sweep across the
screen to its park position. The longer linear
movement of the connecting link, causes the wiper
arm to rotate further than during normal wiping,
parking the wiper arm and blade off screen. A
second slip ring on the underside of the gear wheel,
signals the CCU that the wiper arm has reached its
off screen position and the CCU removes the supply
to the rear screen wiper motor.
The wiper arm is located on the splined shaft from
the motor and secured with a nut. The wiper arm
attachment to the splined shaft has a pivot to which
the remainder of the arm is attached. The two parts
of the arm are connected by a spring which controls
the pressure of the blade on the screen to a
predetermined amount.
The wiper blade is pushed onto the wiper arm which
has a clip-on feature that allows the blade to pivot.
The wiper blade comprises a lever, two yokes and a
plastic strip. The rubber wiper is fitted to the plastic
strip and held in the yokes. The lever, yokes and
plastic strip ensure that pressure applied by the arm
spring is distributed evenly along the length of the
blade.

WINDSCREEN WASHERS DESCRIPTION
REAR SCREEN WASHER DESCRIPTION
The windscreen washers are operated from the
wash/wipe stalk located on the right hand side of the
steering column. Operation of the windscreen
washers will also operate the windscreen wipers.
The rear washer is operated from a non-latching
push switch located on the fascia to the right of the
instrument pack. Operation of the rear washer
switch operates the washer and the rear wiper for as
long as the switch is depressed. When the switch is
released the rear wiper operates for five cycles
before stopping.
If the wash/wipe stalk is pulled quickly and released,
the washers will operate and the wipers will operate
at slow speed for one cycle. If the stalk is pulled and
held, the washers will operate and the wipers will
operate at slow speed for as long as the switch is
operated. When the stalk is released, the washers
will stop but the wipers will continue for several
cycles before stopping.
Two washer jets are located on the top surface of
the bonnet. Each jet contains two adjustable jets
which can be moved to obtain the correct coverage
of the windscreen. The two jets are connected in
series to a flexible pipe which is routed in the
electrical harness to a washer reservoir. The
reservoir is located inside the right hand wheel arch
behind the wheel arch liner. A non-return valve is
located in the feed pipe to the windscreen washer
jets to prevent washer fluid siphoning back to the
reservoir.
The rear washer uses the same reservoir as the
windscreen washers. A second electric washer
pump is fitted to the reservoir and supplies washer
fluid, via a pipe located in the wiring harness, to a
single washer jet which is fitted in the rear wiper
arm. The jet has four jets which direct washer fluid to
each side of the wiper blade. A non-return valve is
located in the feed pipe to the rear screen washer jet
to prevent washer fluid siphoning back to the
reservoir.
The reservoir is moulded from plastic and has a
capacity of approximately 4.0 litres (7 pints). The
reservoir has two ports which allow for the
attachment of two washer pumps. The flexible pipe
from the windscreen washer jets is connected to the
forward of the two electric washer pumps. The
reservoir has a filler tube which protrudes into the
engine compartment. The tube is sealed by a
removable cap. A filter is located in the neck of the
filler tube and prevents the ingress of particulate
matter when replenishing the reservoir. The filter can
be removed for cleaning.

handset.
CDL Switch
The CDL switch is located in the centre console. The
CDL switch allows the occupants to CDL lock the
vehicle from inside without arming the alarm. The
CDL switch is inoperative if the inertia switch is
tripped. The CDL locked state can be removed by
operation of the CDL switch, remote handset or key
unlock in the drivers door key barrel. If the inertia
switch is tripped while the doors are CDL locked and
the ignition is on, all doors will automatically unlock.

DESCRIPTION AND OPERATION
With the vehicle CDL or superlocked, turning the top
of the key once to the front of the vehicle will
mechanically unlock the driver’s door only. The
vehicle will enter the Emergency Key Access (EKA)
state. Refer to Emergency Key Access (EKA) in this
section.
On vehicles with alarm not selected (market option):
With the vehicle CDL locked, turning the top of the
key once to the front of the vehicle will unlock all the
doors.
If the vehicle is superlocked, turning the top of the
key once to the front of the vehicle will only unlock
the driver’s door for Single Point Entry (SPE). The
remaining door(s) will unlock to the CDL state. If the
key is turned a second time, the remaining door(s)

Remote Locking
Slam Locking
On vehicles with alarm selected:
The driver’s door is designed to prevent slam
locking. The remaining door(s) can be slam locked.
The vehicle can be superlocked by pressing the lock
button on the remote handset once.
On vehicles with alarm not selected (market option):
The vehicle can be CDL locked by pressing the lock
button on the remote handset once.
Remote Unlocking
With the vehicle CDL locked, pressing the unlock
button on the remote handset once will unlock all
doors.
If the vehicle is superlocked, pressing the unlock
button once on the remote handset will only unlock
the drivers door for SPE. The remaining door(s) will
unlock to the CDL state. If the button is pressed a
second time, the remaining door(s) will unlock.
NOTE: If the vehicle is superlocked and
SPE has not been selected in the CCU,
pressing the unlock button once on the
remote handset will unlock all the doors.
Central Locking Notes:
• Locking or unlocking using the vehicle key or
remote handset is prevented if the CCU senses
that the ignition is on.
• Superlocking is prevented if the CCU senses that
one or more doors are open. The CCU will
attempt to CDL lock all doors.
Inertia Switch
The inertia switch is located on the bulkhead in the
engine compartment. With the ignition on and the
alarm disarmed, if the inertia switch is tripped all the
doors will unlock irrespective of their state at the
time. Further locking is prevented unless:
• the ignition is switched off and the driver’s door is
opened and closed
• the driver’s door is opened and closed and the
inertia switch is manually reset by depressing the
button on the top of the switch.
Tail Door
The CCU also controls the tail door release. The tail
door can only be opened if the vehicle is unlocked,
the alarm is not armed and the vehicle is travelling at
not more than 3 mph (5 km/h).

DESCRIPTION AND OPERATION
Latch Motor Protection
To protect the door lock latches from damage, the
CCU will only allow eight changes of state of the
locks in any sixteen second period or less. If eight
changes of state occurs within the sixteen second
period, the CCU will prevent further operation of the
latch motors for a further sixteen second period.
The CCU will always prevent further operation only
when the latch motors are in an unlocked condition.

Alarm/Immobilisation System
The alarm system can be armed and disarmed using
the vehicle key or the remote handset. An
Emergency Key Access (EKA) facility is also
available to disarm the alarm and mobilise the
engine in the event of the remote handset becoming
inoperative or unavailable. The alarm system
monitors the driver’s door, passenger door(s), tail
door, bonnet and roof (3 door models only) using
perimetric sensing. It also monitors movement within
the passenger compartment using volumetric
sensing.
The alarm system also controls the mobilisation and
immobilisation of the engine starter operation and
engine management system. The vehicle can be
immobilised and mobilised using the remote handset
or the vehicle key. Passive immobilisation will occur
if the vehicle is left unattended for a predetermined
period with the alarm not armed.
In certain countries, the alarm system is
programmed not to arm under any circumstances.
NOTE: Hazard warning light confirmation
of alarm arm or disarm is market
programmable and therefore may not be
operative on certain variants.
DESCRIPTION AND OPERATION

ELECTRICAL
Perimetric Sensing
Alarm - Key Operation
Perimetric sensing is invoked by the CCU to monitor
entry to the vehicle after the alarm has been set.
The panel open switches on the driver’s door,
passenger door(s), tail door, bonnet and roof (3 door
only) are all monitored by the CCU.
Arming and disarming using the vehicle key in the
driver’s door key barrel will be ignored if the CCU
senses that the ignition is on. In certain markets the
alarm system is programmed not to arm under any
circumstances, in these cases key operation will
only operate the door locking facility as described in
Key Locking/Unlocking.
If a panel is opened after the alarm has been set,
the alarm will be triggered. The horn or BBUS will
sound and the hazard warning lights will operate. On
3 door models, if the roof is off when the alarm is
armed, further operation of the roof off switch will not
trigger the alarm.
NOTE: Using the vehicle key in the
driver’s door key barrel will not enable the
volumetric sensing.
Key Arm
Volumetric Sensing
The volumetric sensor is located in a central position
on the roof panel, behind the headlining. The
volumetric sensor monitors movement inside the
vehicle to detect any possible intrusion. The vehicle
can be armed with the volumetric sensor disabled to
avoid accidental triggering of the alarm if a pet is in
the vehicle for instance. The volumetric sensor is
also inoperative if the CCU senses that a panel has
been left open, with the exception of the bonnet.
A fifteen second delay is initiated after arming of the
alarm before signals from the volumetric sensor are
interpreted as an intrusion. This precaution is
included in the CCU software to avoid accidental or
nuisance triggering of the alarm.
If the alarm has been triggered, the CCU will ignore
further volumetric sensor signals for the duration of
the alarm sounding. The CCU will delay volumetric
sensing for a further 15 seconds after the alarm has
stopped sounding, unless ten triggers have been
sensed by the volumetric sensor since the alarm
was last armed.
The volumetric gain setting is controlled by the VIN
stored in the CCU. The VIN informs the CCU of the
vehicle body and roof type to avoid under or over
sensitivity.
If battery supply voltage falls to below 9 Volts, the
CCU will ignore inputs from the volumetric sensor.

DESCRIPTION AND OPERATION
The vehicle alarm can be fully armed by turning the
top of the key to the rear of the vehicle once with all
panels closed. The Vehicle will be CDL locked, the
hazard warning lights will flash three times. The
alarm LED will fast flash for ten seconds and then
change to slow flash. Perimetric sensing, engine
immobilisation and starter relay disable will be
activated.
The vehicle alarm can also be fully armed by turning
the top of the key to the rear of the vehicle a second
time, within one second of the first turn, with all the
panels closed. The vehicle will be superlocked, the
hazard warning lights will flash three times. The
alarm LED will fast flash for ten seconds and then
change to slow flash. Perimetric sensing, engine
immobilisation and starter relay disable will be
activated.
ELECTRICAL
Key Disarm
The driver’s door only will be mechanically unlocked.
The alarm LED will continue to slow flash, perimetric
and volumetric sensing will be disabled, but engine
immobilisation and starter relay disable will remain
activated.
The miss-lock warning sound is market selectable
and therefore may not be operative in specific
markets. When the CCU enters a partially armed
state, there is no hazard warning flasher operation,
the alarm LED will be extinguished for 10 seconds
and will then slow flash.
To deactivate the engine immobilisation and starter
relay disable, the EKA code must be correctly
entered (Refer to EKA description in this section).
The CCU will partially alarm the vehicle according
the priority of the panel left open. The panel priority
is driver’s door, passenger door(s), tail door and
bonnet with the driver’s door being the highest
priority and the bonnet being the lowest.
Alarm - Remote Handset Operation
Drivers Door
In certain markets, the alarm system is programmed
not to arm under any circumstances. In these cases
the remote handset will only operate the door
locking facility as described in remote handset
lock/unlock.
If the driver’s door is open and a lock request is
made, the CCU will CDL lock the closed doors,
suspend superlocking and volumetric sensing and
monitor the panel left open.
Vehicle state changes:
Remote Handset Arm
The vehicle alarm can be fully armed by pressing
the lock button on the remote handset once with all
panels closed. The Vehicle will be superlocked, the
hazard warning lights will flash three times. The
alarm LED will fast flash for ten seconds and then
change to slow flash. Perimetric and volumetric
sensing, engine immobilisation and starter relay
disable will be activated.
Remote Handset Disarm
The vehicle can be fully disarmed by pressing the
unlock button once on the remote handset. The
hazard warning lights will flash once and the alarm
LED will go off. The perimetric and volumetric
sensing will be disabled and engine immobilisation
and starter relay disable will be deactivated.
• If the driver’s door is open and a lower priority
panel closes, the CCU will give a miss-lock
sound and remain in the driver’s door partial arm
condition.
• If the driver’s door closes, the CCU will sound a
miss-lock warning and remain in the driver’s door
partial arm condition. If the driver’s door is
opened, the alarm will be triggered.
• If the driver’s door closes and one or more lower
priority panels are open and a lock request is
made, the CCU will CDL lock the closed door(s)
and enter the partial arm state of the panel open
with the next highest priority.
• If the driver’s door closes and all other panels are
closed and a lock request is made, the CCU will
lock the doors and arm the alarm.
Partial Arming
If one or more of the panels is left open, the CCU will
attempt to partially arm as much of the vehicle as
possible. If a failure of a panel open switch or wiring
occurs, the CCU will partially arm the alarm in the
same manner as if a panel is left open.
When the alarm is armed with one or more panels
open, the CCU will sound a miss-lock warning from
the horn or BBUS to tell the driver that a panel is
open.

ELECTRICAL
Passenger Door(s)
Bonnet
If one or more of the passenger doors are open and
the driver’s door closes and a lock request is made,
the CCU will CDL lock the closed door(s), suspend
superlocking and volumetric sensing and monitor the
panel(s) left open. Vehicle state changes:
If the bonnet is open and all higher priority panels
are closed and a lock request is made, the CCU will
allow superlocking of the passenger and driver’s
doors and volumetric sensing and monitor the panel
left open.
• If one or more passenger door(s) are open and a
lower priority panel closes, the CCU will sound a
miss-lock warning and remain in the passenger
door partial arm condition.
• If the passenger door(s) close(s) and one or
more lower priority panels remain open, the CCU
will sound a miss-lock warning and enter the
partial arm condition of the panel with the next
highest priority.
• If the passenger door(s) closes and all other
panels are closed, the CCU will arm the alarm
door sense switches for the closed door(s).
Vehicle state changes:
NOTE: The passenger door(s) can be slam
locked.
• If the bonnet closes and all other panels are
closed, the CCU will enter the locked and armed
condition.
Miss-lock Warning
When the CCU enters a partial armed condition or
the alarm is armed with the tail door window down,
the CCU will sound a miss-lock warning. The
miss-lock warning is market selectable. The
miss-lock warning is sounded from either the vehicle
horn for a period of 0.02 seconds or from the BBUS
for a period of 0.1 seconds.
Tail Door
Alarm Activated
If the tail door is open and all higher priority panels
are closed and a lock request is made, the CCU will
allow superlocking of the passenger and driver’s
doors, suspend volumetric sensing and monitor the
panel(s) left open.
