MAINTENANCE AND REPAIR
MAINTENANCE AND LUBRICATION
NORMAL VEHICLE USE
Fuel Filter Replacement
The maintenance instructions contained in the
maintenance schedule are based on the assumption
that the vehicle will be used for the following reasons:
l To carry passengers and cargo within the limitation
of the tire inflation prassure. Refer to “Tire and Wheel”
in section 2E.
l To be driven on reasonable road surfaces and within
legal operating limits.
Replace the engine fuel filter every.
l Gasoline Engine : 60,000km (36,000 miles)
l Diesel Engine : 45,000km (24,000 miles)
EXPLANATION OF SCHEDULED
MAINTENANCE SERVICES
The services listed in the maintenance schedule are
further explained below. When the following maintenance
services are performed, make sure all the parts are
replaced and all the necessary repairs are done before
driving the vehicle. Always use the proper fluid and
lubricants.
Spark Plug Replacement
Replace spark plugs with same type.
l Type : BOSCH : F8DC4
BERU : 14F-8DU4
Champion : C11YCC
l Gap : 0.8 ± 0.1 mm
Spark Plug Wire Replacement
Clean wires and inspect them for burns, cracks or other
damage. Check the wire boot fit at the Distributor and at
the spark plugs. Replace the wires as needed.
Brake System Service
Check the disc brake pads or the drum brake linings.
Check the pad and the lining thickness carefully.
Engine Oil and Oil Filter Change
Tire and Wheel Inspection and Rotation
Always use above the API SH grade or recommended
engine oil.
Check the tires for abnormal wear or damage. To
equalize wear and obtain maximum tire life, rotate the
tires. If irregular or premature wear exists, check the
wheel alignment and check for damaged wheels. While
the tires and wheels are removed, inspect the brakes.
Engine Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel
economy and cold weather operation. Lower viscosity
engine oils can provide better fuel economy and cold
weather performance; however, higher temperature
weather conditions require higher viscosity engine oils
for satisfactory lubrication. Using oils of any viscosity
other than those viscosities recommended could result
in engine damage.
Cooling System Service
Drain, flush and refill the system with new coolant. Refer
to “Recommended Fluids And Lubricants” in this section.
Air Cleaner Element Replacement
Clean the air cleaner element every.
l Gasoline Engine : 15,000km (10,000 miles)

0B-12 GENERAL INFORMATION
OWNER INSPECTIONS
AND SERVICES
WHILE OPERATING THE VEHICLE
Horn Operation
Blow the horn occasionally to make sure it works. Check
all the button locations.
Brake System Operation
Be alert for abnormal sounds, increased brake pedal
travel or repeated puling to one side when braking. Also,
if the brake warning light goes on, or flashes, something
may be wrong with part of the brake system.
Exhaust System Operation
Be alert to any changes in the sound of the system or
the smell of the fumes. These are signs that the system
may be leaking or overheating. Have the system
inspected and repaired immediately.
Tires, Wheels and Alignment Operation
Be alert to any vibration of the steering wheel or the
seats at normal highway speeds. This may mean a wheel
needs to be balanced. Also, a pull right or left on a
straight, level road may show the need for a tire pressure
adjustment or a wheel alignment.
5. Add oil, if needed, to keep the oil level above the
lower mark. Avoid overfilling the engine, since this
may cause engine damage.
6. Push the indicator all the way back down into the
engine after taking the reading.
If you check the oil level when the oil is cold, do not run
the engine first. The cold oil will not drain back to the
pan fast enough to give a true oil level reading.
Engine Coolant Level and Condition
Check the coolant level in the coolant reservoir tank
and add coolant if necessary. Inspect the coolant.
Replace dirty or rusty coolant.
Windshield Washer Fluid Level
Check the washer fluid level in the reservoir. Add fluid if
necessary.
AT LEAST TWICE A MONTH
Tire And Wheel Inspection and Pressure
Check
Check the tire for abnormal wear or damage. Also check
for damaged wheels. Check the tire pressure when the
tires are cold ( check the spare also, unless it is a
stowaway). Maintain the recommended pressures. Refer
to “Tire and Wheel” is in section 0B.
AT LEAST MONTHLY
Steering System Operation
Light Operation
Be alert to changes in the steering action. An inspection
is needed when the steering wheel is hard to turn or
has too much free play, or is unusual sounds are noticed
when turning or parking.
Check the operation of the license plate light, the
headlights (including the high beams), the parking lights,
the fog lights, the taillight, the brake lights, the turn
signals, the backup lights and the hazard warning flasher.
Headlight Aim
Fluid Leak Check
Take note of the light pattern occasionally. Adjust the
headlights if the beams seem improperly aimed.
Periodically inspect the surface beneath the vehicle for
water, oil, fuel or other fluids, after the vehicle has been
parked for a while. Water dripping from the air
conditioning system after use is normal. If you notice
fuel leaks or fumes, find the cause and correct it at once.
AT EACH FUEL FILL
A fluid loss in any (except windshield washer) system
may indicate a problem. Have the system inspected and
repaired immediately.
Engine Oil Level
Check the oil level and add oil if necessary. The best
time to check the engine oil level is when the oil is warm.
1. After stopping the engine, wait a few minutes for the
oil to drain back to the oil pan.
2. Pull out the oil level indicator (dip stick).
3. Wipe it clean, and push the oil level indicator back
down all the way.
4. Pull out the oil level indicator and look at the oil level
on it.
Downloaded from www.Manualslib.com manuals search engine
AT LEAST TWICE A YEAR
Power Steering System Reservoir Level
Check the power steering fluid level. Keep the power
steering fluid at the proper level. Refer to Section 6A,
Power Steering System.
Brake Master Cylinder Reservoir Level
Check the fluid and keep it at the proper level. A low
fluid level can indicate worn disc brake pads which may
need to be serviced. Check the breather hole in the
reservoir cover to be free from dirt and check for an
open passage.
GENERAL INFORMATION 0B-13
Weather-Strip Lubrication
AT LEAST ANNUALLY
Apply a thin film silicone grease using a clean cloth.
Lap and Shoulder Belts Condition and
Operation
EACH TIME THE OIL IS CHANGED
Brake System Inspection
This inspection should be done when the wheels are
removed for rotation. Inspect the lines and the hoses
for proper hookup, binding, leaks, cracks, chafing, etc.
Inspect the disc brake pads for wear. Inspect the rotors
for surface condition. Inspect other brake parts, the
parking brake, etc., at the same time. Inspect the brakes
more often if habit or conditions result in frequent braking.
Steering, Suspension and Front Drive Axle
Boot And Seal Inspection
Inspect the front and rear suspension and the steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
line and the hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and inspect the drive axle
boot and seals for damage, tears or leakage. Replace
the seals if necessary.
Exhaust System Inspection
Inspect the complete system (including the catalytic
converter if equipped). Inspect the body near the exhaust
system. Look for broken, damaged, missing, or out-ofposition parts as well as open seams, holes, loose
connections, or other conditions which could cause heat
buildup in the floor pan or could let exhaust fumes seep
into the trunk or passenger compartment.
Inspect the belt system including: the webbing, the
buckles, the latch plates, the retractor, the guide loops
and the anchors.
Movable Head Restraint Operation
On vehicles with movable head restraints, the restraints
must stay in the desired position.
Spare Tire and Jack Storage
Be alert to rattles in the rear of the vehicle. The spare
tire, all the jacking equipment, and the tools must be
securely stowed at all times. Oil the jack ratchet or the
screw mechanism after each use.
Key Lock Service
Lubricate the key lock cylinder.
Body Lubrication Service
Lubricate all the body door hinges including the hood,
the fuel door, the rear compartment hinges and the
latches, the glove box and the console doors, and any
folding seat hardware.
Underbody Flushing
Flushing the underbody will remove any corrosive
materials used for ice and snow removal and dust control.
At least every spring clean the underbody. First, loosen
the sediment packed in closed areas of the vehicle. Then
flush the underbody with plain water.
Throttle Linkage Inspection
Engine Cooling System
Inspect the throttle linkage for interference or binding,
damaged, or missing parts. Lubricate all linkage joints
and throttle cable joints, the intermediate throttle shaft
bearing, the return spring at throttle valve assembly, and
the accelerator pedal sliding face with suitable grease.
Check the throttle cable for free movements.
Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling
system with new coolant. Keep the coolant at the proper
mixture in order to ensure proper freeze protection,
corrosion protection and engine operating temperature.
Inspect the hoses. Replace the cracked, swollen, or
deteriorated hoses. Tighten the clamps. Clean the
outside of the radiator and the air conditioning
condenser. Wash the filler cap and the neck. Pressure
test the cooling system and the cap in order to help
ensure proper operation.
Engine Drive Belts
Inspect all belts for cracks, fraying, wear and proper
tension. Adjust or replace the belts as needed.
Hood Latch Operation
When opening the hood, note the operation of the
secondary latch. It should keep the hood from opening
all the way when the primary latch is released. The hood
must close firmly.

DIAGNOSIS
OIL LEAK DIAGNOSIS
Most fluid oil leaks are easily located and repaired by
visually finding the leak and replacing or repairing the
necessary parts. On some occasions a fluid leak may
be difficult to locate or repair. The following procedures
may help you in locating and repairing most leaks.
Finding the Leak
1. Identify the fluid. Determine whether it is engine oil,
automatic transmission fluid, power steering fluid, etc.
2. Identify where the fluid is leaking from.
2.1 After running the vehicle at normal operating
temperature, park the vehicle over a large sheet
of paper.
2.2 Wait a few minutes.
2.3 You should be able to find the approximate
location of the leak by the drippings on the
paper.
3. Visually check around the suspected component.
Check around all the gasket mating surfaces for
leaks. A mirror is useful for finding leaks in areas that
are hard to reach.
4. If the leak still cannot be found, it may be necessary
to clean the suspected area with a degreaser, steam
or spray solvent.
4.1 Clean the area well.
4.2 Dry the area.
4.3 Operate the vehicle for several miles at normal
operating temperature and varying speeds.
4.4 After operating the vehicle, visually check the
suspected component.
4.5 If you still cannot locate the leak, try using the
powder or black light and dye method.
Powder Method
1. Clean the suspected area.
2. Apply an aerosol-type powder (such as foot powder)
to the suspected area.
3. Operate the vehicle under normal operating
conditoins.
4. Visually inspect the suspected component. You
should be able to trace the leak path over the white
powder surface to the source.
Black Light and Dye Method
A dye and light kit is available for finding leaks, Refer to
the manufacturer's directions when using the kit.
1. Pour the specified amount of dye into the engine oil
fill tube.
Downloaded from www.Manualslib.com manuals search engine
2. Operate the vehicle normal operating conditions as
directed in the kit.
3. Direct the light toward the suspected area. The dyed
fluid will appear as a yellow path leading to the
source.
Repairing the Leak
Once the origin of the leak has been pinpointed and
traced back to its source, the cause of the leak must be
determined n order for it to be repaired properly. If a
gasket is replaced, but the sealing flange is bent, the
new gasket will not repair the leak. The bent flange must
be repaired also. Before attempting to repair a leak,
check for the following conditions and correct them as
they may cause a leak.
Gaskets
l The fluid level/pressure is too high.
l The crankcase ventilation system is malfunctioning.
l The fasteners are tightened improperly or the threads

are dirty or damaged.
The flanges or the sealing surface is warped.
There are scratches, burrs or other damage to the
sealing surface.
The gasket is damaged or worn.
There is cracking or porosity of the component.
An improper seal was used (where applicable).
Seals

GENERAL INFORMATION
CLEANLINESS AND CARE
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousanths of
an inch. When any internal engine parts are serviced,
care and cleanliness are important. A liberal coating of
enigne oil should be applied to friction areas during
assembly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part of the repair
procedure. This is considered standard shop practice
even if not specifically stated.
Whenever valve train components are removed for
service, they should be kept in order. They should be
installed in the same locations, and with the same mating
surfaces, as when they were removed.
Downloaded from www.Manualslib.com manuals search engine
Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnect
cables may result in damage to wire harness or other
electrical parts.
ON-ENGINE SERVICE
Caution: Disconnect the negative battery cable
before removing or installing any electrical unit, or
when a tool or equipment could easily come in
contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal
injury and damage to the vehicle. The ignition must
also be in LOCK unless otherwise noted.
Notice: Any time the air cleaner is removed, the intake
opening should be covered. This will protect against
accidental entrance of foreign material, which could
follow the intake passage into the cylinder and cause
extensive damage when the engine is started.

GENERAL INFORMATION
CLEANLINESS AND CARE
ON-ENGINE SERVICE
An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the ten-thousanths of
an inch. When any internal engine parts are serviced,
care and cleanliness are important. A liberal coating of
enigne oil should be applied to friction areas during
assembly, to protect and lubricate the surfaces on initial
operation. Proper cleaning and protection of machined
surfaces and friction areas is part of the repair
procedure. This is considered standard shop practice
even if not specifically stated.
Whenever valve train components are removed for
service, they should be kept in order. They should be
installed in the same locations, and with the same mating
surfaces, as when they were removed.
Battery cables should be disconnected before any major
work is performed on the engine. Failure to disconnect
cables may result in damage to wire harness or other
electrical parts.
Caution: Disconnect the negative battery cable before removing or installing any electrical unit, or
when a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help prevent personal injury and
damage to the vehicle. The ignition must also be in
LOCK unless otherwise noted.
Downloaded from www.Manualslib.com manuals search engine
Notice: Any time the air cleaner is removed, the intake
opening should be covered. This will protect against
accidental entrance of foreign material, which could
follow the intake passage into the cylinder and cause
extensive damage when the engine is started.

DIAGNOSIS
Most fluid oil leaks are easily located and repaired by
visually finding the leak and replacing or repairing the
necessary parts. On some occasions a fluid leak may
be difficult to locate or repair. The following
procedures may help you in locating and repairing
most leaks.
1. Pour the specified amount of dye into the engine
oil fill tube.
2. Operate the vehicle normal operating conditions
as directed in the kit.
3. Direct the light toward the suspected area. The
dyed fluid will appear as a yellow path leading to
the source.
Finding the Leak
Repairing the Leak
1. Identify the fluid. Determine whether it is engine
oil, automatic transmission fluid, power steering
fluid, etc.
2. Identify where the fluid is leaking from.
2.1 After running the vehicle at normal operating
temperature, park the vehicle over a large
sheet of paper.
2.2 Wait a few minutes.
2.3 You should be able to find the approximate
location of the leak by the drippings on the
paper.
3. Visually check around the suspected component.
Check around all the gasket mating surfaces for
leaks. A mirror is useful for finding leaks in areas
that are hard to reach.
4. If the leak still cannot be found, it may be
necessary to clean the suspected area with a
degreaser, steam or spray solvent.
4.1 Clean the area well.
4.2 Dry the area.
4.3 Operate the vehicle for several miles at
normal operating temperature and varying
speeds.
4.4 After operating the vehicle, visually check the
suspected component.
4.5 If you still cannot locate the leak, try using the
powder or black light and dye method.
Once the origin of the leak has been pinpointed and
traced back to its source, the cause of the leak must
be determined n order for it to be repaired properly. If
a gasket is replaced, but the sealing flange is bent,
the new gasket will not repair the leak. The bent flange
must be repaired also. Before attempting to repair a
leak, check for the following conditions and correct
them as they may cause a leak.
Powder Method
l
1. Clean the suspected area.
2. Apply an aerosol-type powder (such as foot
powder) to the suspected area.
3. Operate the vehicle under normal operating
conditions.
4. Visually inspect the suspected component. You
should be able to trace the leak path over the white
powder surface to the source.

l It show that the throttle valve (19) is closed or very partially
opened and the vacuum pressure in intake manifold is high.
The blowby gas in the crankcase in partial load flows into
the intake manifold through the vent line (20) after passing
the air conditioner bracket (6) and the filter (4). The air
reentered into the intake manifold will be dilluted on the flow
through the restriction hole (11) in the vent line (10).
The circulated engine oil is separated at the air conditioner
bracket (6) and then returns into the oil pan through the
drain pipe (7).
The vacuum pressure generated at the crankcase sucks
fresh air from intake air line(13) through the air admission
and vent connection (17,18).
The fresh air prevents engine oil from being contami-nated
and the air admission and vent connection (17,18) is
designed to control the rapid pressure changes in intake
air line (13).
Operation at Full-Load
l The throttle valve (19) is fully opened.
All the blowby gases flow into the intake air duct (13) after
passing through the oil separator (15,16) of the cylinder
head cover (14) when fully loaded. This dilluted air will be
supplied to the combustion chamber through the intake
manifold (12).

l The throttle valve(6) is closed or very partially opened, and
the vacuum pressure in intake manifold is high.
The blow-by gas and the fresh air that is additionally supplied
through the vent connection(D) in the crankcase in partial
load gets supplied to the combustion chamber from the crank
chamber(12) through the oil separation chamber(11), airconditioner bracket(10), vent line(9), and restrictor(7)
mounted to the cylinder head.
The circulated engine oil returns to the oil pan through the
oil return pipe(13) at the bottom of oil separation
chamber(11).
The fresh air gets supplied to the crank chamber(12) through
the HFM sensor(1), intake air duct(4), vent line(5), oil
separation chamber(3), chain housing(17), and the timing
gear case cover(15).
The additional supply of the fresh air is needed to prevent
from forming the residues of the engine oil.

Milling of the Prechamber Sealing Surface
Notice
The prechamber sealing surface may only be remachined
once with the cylinder head fitted. It is essential to adhere
to the specified projection ‘C’ of the prechamber of 7.6 8.1mm.
This ensures that the required clearance exists between
prechamber and piston crown with the piston in TDC. For
this reason, spacer rings should be inserted on remachined
sealing surfaces.
Tightening Torque
0.3, 0.6, 1.0 mm
If a spacer ring is already fitted, or a marking is made on the
cylinder head, the cylinder head must be removed and size
‘C’ measured if further remachining is necessary on a
prechamber sealing surface.

8. Remeasure size ‘X’ and compare it with the first
measurement and determine the thickness of spacer ring.
Ex Size before machining
Size after machining
25.7 mm
25.5 mm
The spacer ring should be selected so that it is at least
0.1mm and not more than 0.3mm thicker than the
measured on the sealing surface. In this example, the
necessary thickness of spacer ring should be within
0.3 ~ 0.5mm and the thickness of spacer ring to be
installed is 0.3mm.

Preheating System
General information
The preheating system consists of control, coolant temperature
sensor and glow plugs.
l Control relay - preheating time.
l Coolant temperature sensor.
l Glow plug.
Downloaded from www.Manualslib.com manuals search engine
3 Wire Terminal
4 Glow Plug
OM600 ENGINE ELECTRICAL 1E3-3
1. Preheating time - control relay.
Control relay functions as followings :
l Switching of preheating current.
l Indication of preheating finish.
l Control of preheating sequence.
l Indication of fault.
2. Coolant temperature sensor.
Coolant temperature sensor senses coolant’s temperature
and signals it to the preheating relay continuously.
3. Glow plug
The glow plug parts are housing with M12 ´ 1.25 thread
and heating pin in housing. It is connected in a parallel circuit
with the specified voltage of 11.5V.
The heating element has a heating coil and a control coil
and they are connected in series.
1. Control Coil
2. Heater Coil
4. Current and temperature of glow plug
l Current of glow plug
While the preheating system operates, current of about
30A flows in each glow plug and temperature of heating
coil rises very fast.
Due to the rise of temperature, the resistance of control
coil increases therefore the current is controlled to
about 8~15A and that protects the glow plug from overheating.
l Temperature of glow plug
The temperature of the glow plug reaches up to 900°C
after about 9 seconds and up to 1,050°C after 30
seconds.
Downloaded from www.Manualslib.com manuals search engine
1E3-4 OM600 ENGINE ELECTRICAL
Preheating System Operation
1. Preheating before start.
Preheating time is different by coolant temperature and it is
on until the glow indicator light goes off.
2. Preheating after start.
Preheating continues for max. 60 seconds to rise in
characteristic of warming-up on engine after starting too.
3. Monitoring on glow plug.
Glow plugs are monitored by low current by the micro
processor in control relay respectively while running the
engine.
If glow indicator comes on after starting for about one minute,
it indicates on or several plugs are faulty.
Problem
Possible Cause
1
Glow indicator does not come on in preheating
time and comes on after starting the engine.
-
2
Glow indicator does not come on while
preheating and after starting engine.
- Faulty glow indicator
- Faulty circuit of glow indicator
- Faulty control relay
3
Glow indicator does not come on and engine’s
starting is difficult or does not start at all.
-
4

Function of the Fuel Pressure Regulator
The fuel pressure regulator maintains the fuel pressure in the
fuel line with the pressure of 3.2 bars to 3.8 bars according to
the intake manifold pressure. This operating pressure cannot
be changed, and the fuel injection volume will be only
determined by the injection time. Over supplied fuel returns to
the fuel tank through the return line.
<Operating at full load>
There is no negative pressure applied to the spring chamber(9)
during the full load, and it is separated from the fuel chamber(8)
by the diaphragm(5).
When the fuel pressure goes up, the diaphragm forces the
compression spring(6) in the direction of compression . At this
moment, the valve(3) sticks to the diaphragm by the fuel
pressure, and the fuel return line(2) opens. The fuel over
supplied returns to the fuel tank through the return line.

Fuel Pressure(approx. 3.8 bars)

<Operating at Idle and partial load>
The spring chamber(9) is connected to the intake manifold
with the vacuum hose at the intake pipe connection(7). The
negative pressure generated in the intake manifold activates
the diaphragm, and thus the fuel pressure gets reduced to the
rate of the operating extent of the diaphragm by the intake
manifold's negative pressure.
Consequently, the fuel pressure in the fuel distributor changes
by the intake manifold's negative pressure, and the injector's
fuel pressure gets reduced independently to the throttle valve's
position. Thus, the fuel injection volume can only be determined
according to the injector's injecting duration.

Functions
The fuel vaporization control system is installed to inhibit the
fuel vaporized gas from discharging into the atmosphere. The
fuel vaporized gas that is accumulated in the canister abstracts
through the purge switchover valve purification during the
engine combustion (except the decreasing mode) and coolant
temperature of over 80°C. For this reason, the ECU transacts
the engine speed, air inflow quantity, coolant temperature, and
intake temperature.
The purge switchover valve is activated by the ECU frequency
according with the engine rotating speed to adjust the
purification rate. The purification rate is determined by the
continuous valve opening interval.
The purge switchover valve is activated by the ECU for the
following conditions :
l Coolant temperature of over 80°C
l Engine speed of over 1000rpm
l 2 Minutes after starting
l When the fuel cut-off mode is not activated

M161 ENGINE CONTROLS 1F2-47
Function of the Fuel Pressure Regulator
The fuel pressure regulator maintains the fuel pressure in the
fuel line with the pressure of 3.2 bars to 3.8 bars according to
the intake manifold pressure. This operating pressure cannot
be changed, and the fuel injection volume will be only
determined by the injection time. Over supplied fuel returns to
the fuel tank through the return line.
<Operating at full load>
There is no negative pressure applied to the spring chamber(9)
during the full load, and it is separated from the fuel chamber(8)
by the diaphragm(5).
When the fuel pressure goes up, the diaphragm forces the
compression spring(6) in the direction of compression . At this
moment, the valve(3) sticks to the diaphragm by the fuel
pressure, and the fuel return line(2) opens. The fuel over
supplied returns to the fuel tank through the return line.

Intake Manifold Negative Pressure(0 bar)
<Operating at Idle and partial load>
The spring chamber(9) is connected to the intake manifold
with the vacuum hose at the intake pipe connection(7). The
negative pressure generated in the intake manifold activates
the diaphragm, and thus the fuel pressure gets reduced to the
rate of the operating extent of the diaphragm by the intake
manifold's negative pressure.
Consequently, the fuel pressure in the fuel distributor changes
by the intake manifold's negative pressure, and the injector's
fuel pressure gets reduced independently to the throttle valve's
position. Thus, the fuel injection volume can only be determined
according to the injector's injecting duration.

Functions
The fuel vaporization control system is installed to inhibit the
fuel vaporized gas from discharging into the atmosphere. The
fuel vaporized gas that is accumulated in the canister abstracts
through the purge switchover valve purification during the
engine combustion (except the decreasing mode) and coolant
temperature of over 80°C. For this reason, the ECU transacts
the engine speed, air inflow quantity, coolant temperature, and
intake temperature.
The purge switchover valve is activated by the ECU frequency
according with the engine rotating speed to adjust the
purification rate. The purification rate is determined by the
continuous valve opening interval.
The purge switchover valve is activated by the ECU for the
following conditions :
l Coolant temperature of over 80°C
l Engine speed of over 1000rpm
l 2 Minutes after starting
l When the fuel cut-off mode is not activated

3,800/rpm)
The switch valve (7) will be adjusted by ECU and resonance
falp will be colosed. By increasing air flow passage through
dividing intaking air flow toward both air collection housing
(8). This leads to a signficant increase in the torque in the
lower speed range.
2. Resonance flap open (at full load : over 3,800/rpm)
The switch valve (7) will not be adjusted by ECU and
resonance falp (5) will be open. The colllected air in the air
collection housing (8) will not be divided and intaking air
passage will be shorten.

DIAGNOSIS
TIRE DIAGNOSIS
Irregular and Premature Wear
Irregular and premature tire wear has many causes.
Some of them are incorrect inflation pressures, lack of
regular rotation, poor driving habits, or improper wheel
alignment.
Rotate the tires if :
l The front tire wear is different from the rear.
l The left and right front tire wear is unequal.
l The left and right rear tire wear is unequal, Check
wheel alignment if :
l The left and right front tire wear is unequal.
l The wear is uneven across the tread of either front
tire.
l The front tire treads are scuffed with “feather” edges
on the side of the tread ribs or blocks.
Tread Wear Indicators
The original equipment tires have built-in tread wear
indicators to show when the tires need replacement.
These indicators appear as bands when the tire tread
depth becomes shallow. Tire replacement is
recommended when the indicators appear in three or
more grooves at six locations.
Radial Tire Waddle
Waddle is side-to-side movement at the front or rear of
the vehicle. It is caused by the steel belt not being straight
within the tire, or by excessive lateral runout of the tire
or wheel.
The vehicle must be road tested to determine which end
of the vehicle has the faulty tire. The rear end of the
vehicle will shake from side to side or “waddle” if the
waddle tire is on the rear of the vehicle. From the driver’s
seat, it feels as though someone is pushing on the side
of the vehicle. If the faulty tire is on the front of the vehicle,
the waddle is more visual. The front sheet meld appears
to be moving back and forth, and the drivers seat feels
like the pivot point in the vehicle.
Waddle can be diagnosed using the method of
substituting known good tire and wheel assemblies on
the problem vehicle
1. Road test the vehicle to determine if the waddle is
coming from the front or the rear of the vehicle.
2. Install good tires and wheels from a similar vehicle in
place of those on the offending end of the problem
vehicle. If the source of the waddle is not obvious,
change the rear tires.

WHEEL ALIGNMENT 2B-3
3. Road test the vehicle. If there is improvement, install
the original tires to find the offending tire. If there is
no a straight improvement, install good tires in place
of all four offending tires.
4. Install original tires one at a time to find the offending
tire.
RADIAL TIRE LEAD/PULL
Lead/pull is the deviation of the vehicle from a straight
path on a level road with no pressure on the steering
wheel. Lead is usually caused by:
l Incorrect alignment.
l Uneven brake adjustment.
l Tire construction.
The way in which a tire is built can produce lead/pull in
the vehicle.011-center belts on radial tires can cause
the tire to develop a side force while the vehicle rolls
straight down the road. If one side of the tire has even a
little larger diameter than the diameter of the other side,
the tire will tend to roll to one side. Unequal diameters
will cause the tire to develop a side force which can
produce vehicle lead/pull.
The radial lead/pull diagnosis chart should be used to
determine whether the problem originates from an
alignment problem or from the tires. Part of the lead
diagnosis procedure calls for tire rotation that is different
from the proper tire rotation pattern. If a medium- to highmileage tire is moved to the other side of the vehicle, be
sure to check for ride roughness. Rear tires will not cause
lead/pull.

WHEEL ALIGNMENT 2B-5
VIBRATION DIAGNOSIS
Wheel imbalance causes most highway speed vibration
problems. A vibration can remain after dynamic
balancing because:
l A tire is out of round.
l A rim is out of round.
l A tire stiffness variation exists.
Measuring tire and wheel free runout will uncover only
part of the problem, All three causes, known as loaded
radial runout, must be checked using method of
substituting known good tire and wheel assemblies on
the problem vehicle.
Tire Balancing
Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds. Do
an off-vehicle, two-plane dynamic balance first to correct
any imbalance in the tire and wheel assembly.
An on-vehicle finish balance will correct any brake drum,
rotor, or wheel cover imbalance, If balancing does not
correct the high-speed vibration, or if the vibration occurs
at low speeds, runout is the probable cause.
Downloaded from www.Manualslib.com manuals search engine
Preliminary Checks
Prior to performing any work, always road test the car
and perform a careful visual inspection for:
l Obvious tire and wheel runout.
l Obvious drive axle runout.
l Improper tire inflation.
l Incorrect trim height.
l Bent or damaged wheels.
l Debris build-up on the tire or the wheel.
l Irregular or excessive tire wear.
l Improper tire bead seating on the rim,
l Imperfections in the tires, including: tread
deformations, separations, or bulges from impact
damage. Slight sidewall indentations are normal and
will not affect ride quality.

WHEEL ALIGNMENT 2B-9
GENERAL DESCRIPTION AND SYSTEM OPERATION
FOUR WHEEL ALIGNMENT
CASTER
The first responsibility of engineering is to design safe
steering and suspension systems. Each component
must be strong enough to withstand and absorb extreme
punishment. Both the steering system and the front and
the rear suspension must function geometrically with
thebody mass.
The steering and the suspension systems require that
the front wheels self-return and that the tire rolling effort
and the road friction be held to a negligible force in order
to allow the customer to direct the vehicle with the least
effort and the most comfort.
A complete wheel alignment check should include
measurements of the rear toe and camber.
Four-wheel alignment assures that all four wheels will
be running in precisely the same direction.
When the vehicle is geometrically aligned, fuel economy
and tire life are at their peak, and steering and
performance are maximized.
Caster is the tilting 91 the uppermost point of the steering
axis either forward or backward from the vertical when
viewed from the side of the vehicle. A backward tilt is
positive, and a forward tilt is negative. Caster influences
directional control of the steering but does not affect
tire wear. Weak springs or overloading a vehicle will affect
caster. One wheel with more positive caster will pull
toward the center of the car. This condition will cause
the car to move or lean toward the side with the least
amount of positive caster. Caster is measured in degrees.
TOE
Toe-in is the turning in of the tires, while toe-out is the
turning out of the tires from the geometric centerline or
thrust line. The toe ensures parallel rolling of the wheels.
The toe serves to offset the small deflections of the wheel
support system which occur when the vehicle is rolling
forward. The specified toe angle is the setting which
achieves 0 degrees of toe when the vehicle is moving.
Incorrect toe-in or toe-out will cause tire wear and
reduced fuel economy. As the individual steering and
suspension components wear from vehicle mileage,
additional toe will be needed to compensate for the wear.
Always correct the toe dimension last.
Downloaded from www.Manualslib.com manuals search engine
CAMBER
Camber is the tilting of the top of the tire from the vertical
when viewed from the front of the vehicle. When the
tires tilt outward, the camber is positive. When the tires
tilt inward, the camber is negative. The camber angle is
measured in degrees from the vertical. Camber
influences both directional control and tire wear.
If the vehicle has too much positive camber, the outside
shoulder of the tire will wear. If the vehicle has too much
negative camber, the inside shoulder of the tire will wear.

1.6mm
Replace the tire if tread-wear indicator of the tread
grooves appears where marked ' '.
The wear limit of snow tire is the same as normal tire
(1.6mm) and indicator location is marked '¯'.
3. Runout measurement.
l Excessive runout of tires and wheels can cause the
abnormal wear of tire. Using a dial indicator, measure
wheel and tire runout.
l Measure radial runout at the rim flange and center of
the tire tread area.
Standard
2.66mm
l Measure lateral runout at the tire bead area of the wheel
and tire sidewall.
Standard
2.03mm
Notice
If runout is excessive, replace the tire or wheel.

ABD SYSTEM DESCRIPTION
General:
The Automatic Brake Differential Lock (ABD) is a traction system by means of brake intervention only, available in
a low speed range (< 60kph).
It workes on m-split roads with sidewise different friction coefficients.
The spinning driven wheel is braked and the drive torque can be transferred to the wheel on the high- m side.
During ABD active, the ABD information lamp is blinking.
The temperature of the brakes is calculated by a mathematical model and ABD is switched passive if the calculated
temperature is greater than a threshold value(500°C).
ABD is permitted again, when the calculated temperature is less than 350°C.
Control Algorithm:
Speed difference driven wheels [kph]
The input signals for the control algorithm are the filtered
wheel speed signals from the ABS speed processing.
With the speed difference of the driven wheels, the control
deviation is calculated.
If the control deviation exceeds a certain threshold value,
the wheel with the greater slip is braked actively.
The threshold value depends on the vehicle speed:
It is reduced with increasing vehicle speed down to a constant
value.

Pressure Modulation:
Depending on the control deviation and the wheel acceleration of the spinning wheel, pressure increase, hold and
decrease are made.
The pressure modulation is done with the conventional control with the valves. ASV, USV, EV and AV according
the the following table:

Speed Range:
ABD is available in the speed range £ 60 kph.
Above 60 kph vehicle speed, ABD is passive.
It is possible to initiate ABD operation up to a vehicle speed of 55kph.

4F-8 ANTILOCK BRAKE SYSTEM
Temperature Model:
ABD operation is a high thermal load for the brakes.
To avoid any damages at the brakes, the disk temperature is calculated with a mathematical model for each driven
wheel separately. After ignition on, the calculation starts with 30°C and then three different phases are evaluated
separately and added:
ABD operation, braking and coling phase.
If the temperature is highter than 500°C, ABD is disabled for this wheel.
It is permitted again, if the model has calculated down the 350°C.
Lamp Concepts:
The system is equipped with an ABD information lamp, which is blinking during ABD operation.
The activation of the EBD, ABS warning lamp and the ABD info lampo is summarized in the following table:

INTRODUCTION
The BTR Automotive Model 74 Four Speed Automatic Transmission is an electronically controlled overdrive four
speed unit with a lock-up torque converter. The lock-up torque converter results in lower engine speeds at cruise and
eliminates unnecessary slippage. These features benefit the customer through improved fuel economy and noise
reduction. Refer to table 1.1 for details of power, torque and configuration.
Of primary significance is the transmission control unit (TCU) which is a microprocessor based control system. The
TCU utilizes throttle position, rate of throttle opening, engine speed, transmission output speed, transmission sump
temperature, gear selector position and mode selector inputs, and in some applications a ‘kickdown’ switch to control
all shift feel and shift schedule aspects.
The TCU drives a single proportional solenoid multiplexed to three regulator valves to control all shift feel aspects.
The output pressure of this solenoid is controlled as a function of transmission sump temperature to maintain consistent
shift feel throughout the operating range.
Shift scheduling is highly flexible, and several independent schedules are programmed depending on the vehicle.
Typically the ‘NORMAL’ schedule is used to maximise fuel economy and driveability, and a ‘POWER’ schedule is used
to maximise performance. ‘WINTER’ schedule is used to facilitate starting at second gear.
Figure 1.1 details the differences between conventional and electronic transmission control systems.

OPERATOR INTERFACES
There are three operator interfaces associated with the four speed transmission.
They are:
l The gear select lever
l The driving mode selector
l The indicator light
These operator interfaces are described below.
GEAR SELECT LEVER OPERATION
The transmission uses a conventional selector lever. The selector lever can be moved from one position to another
within the staggered configuration of the selector lever gate to positively indicate the gear -selection as shown on
figure 2.1. For information about the gear selections available refer to table 2.1.

First and second gear operation with inhibited engagement of second gear, as
a function of vehicle speed. Engine braking is applied with reduced throttle.
First, second and third gear operation with an inhibited third gear engagement
at high vehicle speed. Refer to the vehicle owner’s manual.
Engine braking is applied with reduced throttle.
First, second, third and fourth gear operation. First to second (1-2), first to third
(1-3), second to third (2-3), second to fourth (2-4), third to fourth (3-4), fourth
to third (4-3), fourth to second (4-2), third to second (3-2), third to first (3-1)
and second to first (2-1), shifts are all available as a function of vehicle speed,
throttle position and the time rate of change of the throttle position (forced
downshift). Lockup clutch may be enabled in 3rd and 4th gears depending on
vehicle type. Refer to the owner’s manual.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch allows the engine to start.
Reverse gear operation, with inhibitor engagement as a function of vehicle
speed, engine speed and throttle position. The inhibitor switch enables reverse
lamp operation.
Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The transmission output shaft is
locked. The inhibitor switch allows the engine to start.
DRIVING MODE SELECTOR
The driving mode selector consists of a mode selection switch and indicator light. The driving mode selector is
located on the centre console. See figure 2,1.
The schedules available to be selected vary with vehicle types. Typically the driver should have the option to select
between ‘NORMAL’ , ‘POWER’ or ‘WINTER’ modes.
When ‘NORMAL’ mode is selected upshifts will occur to maximise fuel economy and the indicator lights remain
extinguished. When ‘POWER’ mode is selected upshifts will occur to give maximum performance and the ‘POWER’
mode indicator light is switched on. When ‘WINTER’ mode is selected, starting at second gear is facilitated, the
‘WINTER’ mode indicator light is switched on and the ‘POWER’ mode indicator light is switched off.
Refer to the vehicle owner’s manual for specific modes for each vehicle type.

CONTROL SYSTEMS
GENERAL
There are two control systems associated with the transmission. The electronic control system monitors vehicle
parameters and adjusts the transmission performance. The hydraulic control system implements the electronic control
system commands.
ELECTRONIC CONTROL SYSTEM
The electronic control system is comprised of sensors, a TCU and seven solenoids. The TCU reads the inputs, and
under software control activates the outputs according to values stored in read only memory (ROM).
The TCU controls the hydraulic control system. This control is via the hydraulic valve body, which contains seven
electro-magnetic solenoids. Six of the seven solenoids are used to control the line pressure, operate the shift valves
and the torque converter lock-up clutch, and to turn on and off the two regulator valves (The two regulator valves
control the shift feel.).
The seventh solenoid is the proportional or variable pressure solenoid (VPS) which works with the two regulator
valves to control shift feel.
Figure 3.1 details a typical TCU control system schematic.
The individual component locations, operation and specifications which make up the electronic control subsystem
are covered in this section.

Transmission Control Unit(TCU)
The TCU is an in-vehicle micro-processor based transmission management system. It is usually mounted in the
vehicle cabin, under the instrument panel, under the seat, behind the side kick panels or under the floor in the
footwell on the passenger side. Different control units are supplied for different vehicle applications.
The TCU contains:
l Processing logic circuits which include a central microcontroller and a back-up memory system.
l Input circuits.
l Output circuits which control external devices such as the variable pressure solenoid (VPS), on/off solenoid
drivers, a diagnostics output and the driving mode indicator light.
The various items which make up the TCU are discussed below.
Processing Logic
Shift schedule and calibration information is stored in an erasable programmable read only memory (EEPROM).
Throttle input calibration constants and the diagnostics information are stored in electrically erasable programmable
read only memory (EEPROM) that retains the memory even when power to the TCU is disconnected.
In operation the software continuously monitors the input values and uses these, via the shift schedule, to determine
the required gear state, At the same time it monitors, via the solenoid outputs, the current gear state. Whenever the
input conditions change such that the required gear state is different to the current gear state, the TCU initiates a
gear shift to bring the two states back into line.
Once the TCU has determined the type of gear shift required the software accesses the shift logic, estimates the
engine torque output, adjusts the variable pressure solenoid ramp pressure then executes the shift.
The TCU continuously monitors every input and output circuit for short or open circuits and operating range. When
a failure or abnormal operation is detected the TCU records the condition code in the diagnostics memory and
implements a limp mode, The actual limp mode used depends upon the failure detected with the object to maintain
maximum driveability without damaging the transmission. In general input failures are handled by providing a default
value. Output failures, which are capable of damaging the transmission, result in full limp mode giving only third or
fourth gear and reverse. For further details of limp modes and memory retention refer to the Diagnostic Section.
The TCU is designed to operate at ambient temperatures between -40 and 85°C . It is also protected against
electrical noise and voltage spikes, however all the usual precautions should be observed, for example when arc
welding or jump starting.
TCU Inputs
To function correctly, the TCU requires engine speed, road speed, transmission sump temperature, throttle position
and gear position inputs to determine the variable pressure solenoid current ramp and on/off solenoid states. This
ensures the correct gear selection and shift feel for all driving conditions.
The inputs required by the TCU are as follows:
l Engine Speed
The engine speed signal is derived from the tachometer signal line, a dedicated sensor or a Controlled Area
Network (CAN).
l Road Speed
4WD (Diesel) - The shaft speed signal is derived from the speedo sensor located on the transfer case. This signal
is transmitted directly to the TCU.
4WD (Gasoline) - The speedo sensor sends the shaft speed signal to the engine control module (ECM). The
information is then transferred to the TCU via the CAN.
l Transmission Sump Temperature
The transmission sump temperature sensor is a thermistor located in the solenoid wiring loom within the transmission.
This sensor is a typical NTC resistor with low temperatures producing a high resistance and high temperatures

AUTOMATIC TRANSMISSION 5A-25
producing a low resistance.
Temperature/Resistance characteristics and location within the solenoid wiring loom are given in tables 3-1 and 32, and figures 3.2 and 3.3.
If the transmission sump temperature exceeds 135°C, the TCU will impose converter lock-up at lower vehicle
speeds and in some vehicles flashes the mode indicator lamp. This results in maximum oil flow through the
external oil cooler and eliminates slippage in the torque converter. Both these actions combine to reduce the oil
temperature in the transmission.

Throttle Position Sensor
The throttle position sensor(TPS) is a resistance potentiometer
mounted on the throttle body of the engine.
It transmits a signal to the TCU proportional to the throttle plate
opening.
The potentiometer is connected to the TCU by three wires:
5 volts positive supply, earth and variable wiper voltage.
Throttle voltage adjustments are as follows:
l Closed throttle voltage is 0.2V to 1.0V.
l Wide open throttle voltage is 3V -4.7V.
These measurements are taken between pins 29 and 27 of
the TCU.
Maintaining good shift feel through the transmission life span
is dependant on having an accurate measure of
the engine throttle position. To achieve this the TCU
continuously monitors the maximum and minimum throttle
potentiometer voltages and, if a change occurs, stores the new
voltage values.
However these limits will be lost and will require relearning
should a new TCU be installed, or the throttle calibration data
is cleared by the execution of a particular sequence, This last
instance depends on the installation, and reference should be
made to the Diagnostics Section of this manual. The relearning
will happen automatically
Gear Position Sensor
The gear position sensor is incorporated in the inhibitor switch
mounted on the side of the transmission case.
(Refer to figure 3.5.) The gear position sensor is a multi-function
switch providing three functions:
l Inhibit starting of the vehicle when the shift lever is in a
position other than Park or Neutral
l Illuminate the reversing lamps when Reverse is
selected indicate to the TCU which lever position has
been selected by way of a varying resistance (Refer to
table 3.3.)

Diagnostics Inputs
The diagnostics control input or K-line is used to initiate the outputting of diagnostics data from the TCU to a diagnostic
test instrument. This input may also be used to clear the stored fault history data from the TCU’s
retentive memory. Connection to the diagnostics input of the TCU is via a connector included in the vehicle’s wiring
harness or computer interface. Refer to the vehicle manufacturer’s manual for the location of the self test
connectors.
Battery Voltage Monitoring Input
The battery voltage monitoring input connects to the positive side of the battery. The signal is taken from the
main supply to the TCU.
If operating conditions are such that the battery voltage at the TCU falls below 11.3V the transmission will adopt a ‘low
voltage’ mode of operating in which shifts into first gear are inhibited. All other shifts are allowed but may not occur
because of the reduced voltage. This condition normally occurs only when the battery is in poor condition.
When system voltage recovers, the TCU will resume normal operation after a 3 second delay period.
TCU Outputs
The outputs from the TCU are supplied to the components described below:
Solenoids
The TCU controls seven solenoids. Solenoids 1 to 6 (S1 to S6) are mounted in the valve body, while Solenoid 7 (S7)
is mounted in the pump cover. The normal state (OPEN/CLOSED) and the functions associated with the solenoids
are detailed in table 3.4. Table 3.5 details the S1 and S2 logic for static gear states. The logic during gear changes for
S1 to S4 and S7 is detailed in table 3.6.

S1 and S2 are normally open On/off solenoids that set the selected gear.
These solenoids determine static gear position by operating the shift valves.
Refer to table 3.5. Note that S1 and S2 solenoids also send signal pressure to allow or prohibit rear band engagement.
S3 and S4 are normally open On/off solenoids that combine to control
shift quality and sequencing. S3 switches the clutch regulator valve off or
on. S4 switches the front band regulator valve off or on.
S5 is a variable force solenoid that ramps the pressure during gear
changes. This solenoid provides the signal pressure to the clutch and
band regulator, thereby controlling the shift pressures.
S6 is a normally open On/off solenoid that sets the high/low level of line
pressure, Solenoid off gives high pressure.
S7 is a normally open On/off solenoid that controls the application of the
converter clutch. Solenoid on activates the clutch.

Figure 3.6- Normally Open (NO) Symbols
Variable Pressure Solenoid Multiplexing System
Friction element shifting pressures are controlled by the variable pressure solenoid (VPS).
Line pressure is completely independent of shift pressure and is a function of throttle position, gear state and engine
speed.
S5 is a proportional or variable pressure solenoid that provides the signal pressure to the clutch and band regulator
valves thereby controlling shift pressures.
VPS pressure is multiplexed to the clutch regulator valve, the band regulator valve and the converter clutch regulator
valve during automatic gearshifts.
A variable pressure solenoid produces a hydraulic pressure inversely proportional to the current applied. During a
gearshift the TCU applies a progressively increasing or decreasing (ramped) current to the solenoid. Current applied
will vary between a minimum of 200 mA and a maximum of 1000 mA, Increasing current decreases output (55)
pressure. Decreasing current increases output (55) pressure.
Line 500 pressure, (approximately 440 to 560 kPa), is the reference pressure for the VPS, and the VPS output
pressure is always below line 500 pressure.
When the VPS is at standby, that is no gearshift is taking place, the VPS current is set to 200 mA giving maximum
output pressure.
Under steady state conditions the band and clutch regulator valve solenoids are switched off. This applies full Line
500 pressure to the plunger and because Line 500 pressure is always greater than S5 pressure it squeezes the S5
oil out between the regulator valve and the plunger. The friction elements are then fed oil pressure equal to Line 500
multiplied by the amplification ratio.
When a shift is initiated the required On/off solenoid is switched on cutting the supply of Line 500 to the plunger.
At the same time the VPS pressure is reduced to the ramp start value and assumes control of the regulator valve by
pushing the plunger away from the valve. The VPS then carries out the required pressure ramp and the timed shift is
completed by switching Off the On/off solenoid and returning the VPS to the standby pressure.
This system enables either the band or clutch or both to be electrically controlled for each gearshift.
Mode Indicator Light
Depending on the application, the mode indicator light may be used to indicate the mode that has been selected or
if an overheat condition exists. The mode indicator light is usually located on the instrument cluster.
Communication Systems
CAN
The controller area network (CAN) connects various control modules by using a twisted pair of wires, to share
common information. This results in a reduction of sensors and wiring. Typical applications include using the engine
controller to obtain the actual engine speed and throttle position, and adding these to the network. The ABS controller
(if fitted) can be used to obtain the road speed signal. This information is then available to the TCU without any
additional sensors.
Downloaded from www.Manualslib.com manuals search engine
AUTOMATIC TRANSMISSION 5A-31
K-Line
The K-line is typically used for obtaining diagnostic information from the TCU. A computer with a special interface is
connected to the TCU and all current faults, stored faults, runtime parameters are then available. The stored fault
codes can also be cleared.
The K-line can be used for vehicle coding at the manufacturer’s plant or in the workshop. This allows for one TCU
design to be used over different vehicle models. The particular code is sent to the microprocessor via the K line and
this results in the software selecting the correct shift and VPS ramp parameters.
HYDRAULIC CONTROL SYSTEM
The hydraulic controls are located in the valve body, pump body and main case.
The valve body contains the following:
l Manual valve,
l Three shift valves,
l Sequence valve,
l solenoid supply pressure regulator valve,
l line pressure control valve,
l clutch apply regulator valve,
l band apply regulator valve,
l S1 to S6, and
l Reverse lockout valve.
l The pump body contains the following:
l Primary regulator valve for line pressure,
l converter clutch regulator valve,
l converter clutch control valve,
l S7,and
l C1 bias valve.
The main case contains the following:
l B1R exhaust valve
The hydraulic control system schematic is shown at figure 3.7.
All upshifts are accomplished by simultaneously switching on a shift valve(s), switching VPS pressure to the band
and/or clutch regulator valve, and then sending the VPS a ramped current. The shift is completed by switching the
regulators off and at the same time causing the VPS to reach maximum . pressure. All downshifts are accomplished
by switching VPS pressure to the band and/or clutch regulator valve and sending a ramped current to the VPS. The
shift is completed by simultaneously switching the regulators off, switching the shift valves and at the same time
causing the VPS to return to stand-by pressure.
The primary regulator valve is located in the pump cover and supplies four line pressures; high and low for forward
gears, and high and low for reverse. This pressure has no effect on shift quality and merely provides static clutch
capacity during steady state operation. Low pressure can be obtained by activating an On/off solenoid with high line
pressure being the default mode.
Torque converter lock-up is initiated by toggling the converter clutch control valve with an On/off solenoid. The actual
apply and release of the clutch is regulated by the VPS via the converter clutch regulator valve. As an additional
safety feature, the lock-up is hydraulically disabled in first and second gear by the bias valve which only supplies oil
to the lock-up solenoid when C1 is applied in third and fourth gears. This prevents the vehicle from being rendered
immobile in the unlikely event of S7 becoming stuck.
The solenoid supply valve provides reference pressure for all the solenoids.

Manual Valve
The manual valve (refer to figure 3.10) is connected to the vehicle selector mechanism and controls the flow of oil to
the forward and reverse circuits. The manual valve function is identical in all forward gear positions except that in the
Manual 1 position an additional supply of oil is directed to the 1-2 shift valve for application of the rear band and the
C4 overrun clutch.
Figure 3.10 - Manual Valve
1-2 Shift Valve
The 1-2 shift valve (refer to figure 3.11) is a two position valve that must be switched to the (2,3,4) position in order to
get any forward gear other than first gear. It is used for all 1-2 and 2-1 gearshifts.
The switching of this valve is achieved by using S1 and/or S2.
During a 1-2 gearshift drive oil from the manual valve passes through to the second gear circuit. During a 2-1
gearshift the band apply feed oil is allowed to exhaust via the 1-2 shift valve.
The 1-2 shift valve works in conjunction with the 3-4 shift valve (described below) to disengage the C4 clutch in first
gear, and engage C4 in second gear. When Manual 1 is selected the C4 clutch and rear band (B2) are engaged.

AUTOMATIC TRANSMISSION 5A-35
2-3 Shift Valve
The 2-3 shift valve (refer to figure 3.12) is a two position valve. It is used on all 2-3 and 3-2 gearshifts.
The switching of this valve is achieved by S2 which is located at the end of the valve spool.
When in the (1,2) position, second gear oil from the 1-2 shift valve is prevented from entering the third gear circuit.
When the valve is moved to the (3,4) position, oil from the second gear circuit is routed to the third gear circuit and the
transmission changes to third gear.
Figure 3.12 - 2-3 Shift Valve
3-4 Shift Valve
The 3-4 shift valve (refer to figure 3,13) is a two position valve. It is used for all 3-4 and 4-3 gearshifts.
The switching of this valve is achieved by S1 which is located at the end of the valve spool.
During a 3-4 gearshift the 3-4 shift valve:
l Exhausts the front band release circuit (B 1R) thereby allowing the application of the front band (B1).
l Connects the inner apply area of the front servo (B 1AI) to the band apply feed circuit (BAF) thus allowing
greater apply forces to the front band.
l Exhausts the overrun clutch circuit (OC) which allows the C4 clutch to disengage.
During a 4-3 gearshift, the C4 clutch is engaged and the front band (B1) is released. These actions are sequenced
by the 4-3 sequence valve (described below).
The 3-4 shift valve also switches during 1-2 and 2-1 gearshifts (see 1-2 shift valve above) where its function is to
apply the overrun clutch (C4) in second gear but to release it in first gear. Note that the C4 clutch is applied in Manual
1 by virtue of the manual valve and the 1-2 shift valve (as described in the 1-2 shift valve section).

4-3 Sequence Valve
The 4-3 sequence valve (refer figure 3.14) is a two position spring loaded valve. It switches during 3-4 and 4-3
gearshifts although it performs no function during the 3-4 shift.
During the 4-3 shift the 4-3 sequence valve delays the connection of the clutch apply feed circuit (CAF) to the BIR
circuit until the BIR circuit has been fully pressurised by using the third gear circuit. This prevents objectionable
engine flare on completion of the 4-3 gearshift.
Figure 3.14 - 4-3 Sequence Valve
Solenoid Supply Pressure Regulator Valve
The solenoid supply valve (refer figure 3.15) supplies a constant pressure to all solenoids (51 to 57). Line pressure
is used as the feed oil to this regulator and the output is termed line 500.
Line Pressure Boost Valve
Line pressure is controlled by 56, which acts as the line pressure boost valve (refer figure 3.15). When 56 pressure
is applied to the end of the PRV it is opposed by spring force and causes LOW line pressure for light throttle
application and cruising.
Heavy throttle application causes the normally open 56 to open (switch Off) thus closing line 500 and opening 56 to
exhaust. Removal of 56 pressure from the PRV results in HIGH line pressure.

Clutch Apply Regulator Valve
The clutch apply regulator valve (refer figure 3.16) is a fixed ratio valve. This valve provides a regulated pressure to
the C1 clutch and controls the rate of change of state of the clutch to give the desired shift quality.
This ratio is 2.25 : 1.
Third gear oil supplied to the valve is regulated to provide an output pressure (CAF) of 2.25 times the S5 signal
pressure when S3 is On. When S3 is Off the output pressure is 2.25 times the line 500 pressure.
Figure 3.16 - Clutch Apply Regulator Valve
Band Apply regulator Valve
The band apply regulator valve (refer figure 3.17) is a fixed ratio valve. It provides a regulated pressure to the front
servo, and controls the rate of change of state of the front band (B1) to give the desired shift quality.
This ratio is 1.4 : 1.
Second gear oil supplied to the valve is regulated to provide an output pressure (BAF) of 1.4 times the S5 signal
pressure when S4 is On. When S4 is Off the output pressure is 1.4 times the line 500 pressure.

5A-38 AUTOMATIC TRANSMISSION
Reverse Lockout Valve
The reverse lockout valve (refer figure 3.18) is a two position valve contained in the upper valve body. This valve
uses 51-52 pressure as a signal pressure and controls the application of the rear band (B2).
While the manual valve is in D,3,2, or 1 positions, drive oil is applied to the spring end of the valve, overriding any
signal pressures and holding the valve in the lockout position. This prevents the application of B2 in any of the
forward driving gears.
When the manual valve is in P, R or N positions, drive oil is exhausted and the reverse lockout valve may be toggled
by S1-S2 pressure.
B2 is applied in P, R, and N provided that the following conditions are satisfied:
1. In P or N, roadspeed < 3 km/h.
2. In R, road speed < 10 km/h.
3. Engine speed < 1400 rpm.
4. For diesel vehicles, throttle < 25%.
5. For gasoline vehicles, throttle < 12%.
Under these conditions, the TCU switches solenoids S1 and S2 to Off. The reverse lockout valve toggles under the
influence of the S1-S2 pressure, to connect the line pressure to the B2 feed. Oil is fed to both the inner and outer
apply areas of the rear servo piston, applying B2.
If any of the above conditions are not satisfied, the TCU switches solenoids S1 and S2 to On. S1- S2 pressure is
exhausted and the valve is held in the lockout position by the spring. In this position, engagement of B2 is prohibited.
This feature protects the transmission from abuse by preventing the undesirable application of B2 at high speed, and
by providing a reverse lockout function.
Note that if the transmission is in failure mode, the rear band will be applied at all times in P, R and N.

AUTOMATIC TRANSMISSION 5A-39
Primary Regulator Valve
The primary regulator valve (PRV) (refer to figure 3.19) regulates the transmission line pressure (or pump output
pressure). This valve gives either high or low line pressure depending on whether S6 is switched Off or On, When S6
is switched On,S6 pressure is applied to the PRV moving it against spring pressure and opening the line pressure
circuit to the pump suction port resulting in reduced line pressure. Low line pressure is used during light throttle
applications and cruising. Heavy throttle will cause S6 to switch Off and thereby cause high line pressure.
This stepped line pressure control has no detrimental effect on shift feel because all shifting pressures are controlled
by separate band and clutch regulator valves, and the output of S5.
When reverse gear is selected, both the low and high line pressure values are boosted to guard against slippage.
This is achieved by applying reverse oil line pressure to the PRV to assist the spring load. The other end of the valve
contains ports for line pressure feedback and 56 pressure.
The PRV also regulates the supply of oil to the converter via the converter feed port. The cascade effect of the PRV
ensures the first priority of the valve is to maintain line pressure at very low engine speeds. When the engine speed
increases and the pump supplies an excess of oil the PRV moves to uncover the converter feed port thereby pressurising
the converter. If there is an excess of oil for the transmission’s needs then the PRV moves further to allow oil to return
to the suction port.

5A-40 AUTOMATIC TRANSMISSION
Converter Clutch Regulator Valve
The converter clutch regulator valve (refer figure 3.20) regulates
the pressure of the oil which applies the converter clutch. Input
oil from the line 500 circuit is regulated within the valve, with
the output pressure being variable according to the signal
pressure from the S5 circuit. Converter clutch apply and release
application is smoothed by electronically varying the S5 circuit
pressure.
Figure 3.20 - Converter Clutch Regulator Valve
Converter Clutch Control Valve
The converter clutch control valve (refer figure 3.21) is a two position valve which applies or releases the converter
clutch.
The switching of this valve is governed by the signal pressure from S7.
When the valve is in the off or released position, converter feed oil from the PRV is directed to the release side of the
converter clutch. After flowing through the converter, oil returns to the converter clutch control valve and is then
directed to the oil cooler.
When the valve is in the on or applied position, regulated oil from the converter clutch regulator valve is directed to
the apply side of the converter clutch. This oil remains within the converter because the converter clutch piston is
sealed against the flat friction surface of the converter cover. To provide oil flow to the cooler the converter clutch
control valve directs converter feed oil from the PRV directly to the cooler circuit.

C1 Bias Valve
The C1 bias valve (refer figure 3.22) ensures that the converter lock-up clutch is only applied in third and fourth
gears. It uses C1 clutch oil pressure as the switching signal since C1 is only applied in third and fourth gears.
Line to 500 oil is routed through the C1 bias valve to S7. The C1 bias valve therefore acts as a safety feature to
ensure drivability in the event of S7 failure.
Figure 3.22- C1 Bias Valve
B1R Exhaust Valve
The B1R exhaust valve (refer figure 3.23) is a two position
spring loaded valve located in the transmission case directly
adjacent to the front servo. It permits the servo release oil to
be rapidly exhausted into the transmission case during
application of the front band (B1). This prevents the need to
force the oil back from the front servo through the valve body
and through the 3-4 shift valve. The spring positions the valve
to prevent oil entering the release area of the servo until the
B1R circuit oil pressure reaches approximately 100 kPa.

POWER TRAIN SYSTEM
The Power Train System consists of:
l A torque converter with single face lock-up clutch
l Four multi-plate clutch assemblies
l Two brake bands
l Two one-way clutches
l Planetary gearset
l Parking mechanism
A conventional six pinion Ravigneaux compound planetary gearset is used with overdrive (fourth gear) being obtained
by driving the carrier.
The cross-sectional arrangement is very modular in nature. Four main sub-assemblies are installed within the case
to complete the build. These sub-assemblies are:
l Gearset-sprag-centre support
l C1 -C2-C3-C4 clutch sub-assembly
l Pump assembly
l Valve body assembly
One, or a combination of selective washers are used between the input shaft flange and the number 4 bearing to
control the transmission end float. This arrangement allows for extensive subassembly testing and simplistic final
assembly during production.
A general description of the operation of the Power Train System is detailed below. Refer to table 4.1 and figure 4.1.
First gear is engaged by applying the C2 clutch and locking the 1-2 One Way Clutch (1-2 OWC). The 1-2 shift is
accomplished by applying the B1 band and overrunning the 1-2 OWC. The 2-3 shift is accomplished by applying the
C1 clutch and releasing the B1 band. The 3-4 shift is accomplished by re-applying the B1 band and overrunning the
3-4 OWC. Reverse gear is engaged by applying the C3 clutch and the B2 band.
The C4 clutch is applied in the Manual 1,2 and 3 ranges to provide engine braking. In addition, the C4 clutch is also
applied in the Drive range for second and third gears to eliminate objectionable freewheel coasting. The B2 band is
also applied in the Manual 1 range to accomplish the low-overrun shift.
Both the front and rear servos are dual area designs to allow accurate friction element matching without the need for
secondary regulator valves. All the friction elements have been designed to provide low shift energies and high static
capacities when used with the new low static co-efficient transmission fluids. Non-asbestos friction materials are used
throughout.

attached to the converter cover, the turbine is splined to the
input shaft and the stator is mounted on the pump housing via
a one way clutch (sprag).
The addition of the damper and piston assembly enables the
torque converter to ‘lock-up’ under favourable conditions. Lockup is only permitted to occur in third and fourth gears under
specified throttle and road speed conditions.
Lock-up is achieved by applying hydraulic pressure to the
damper and piston assembly which couples the turbine to the
converter cover, locking-up the converter and eliminating
unwanted slippage. Whenever lock-up occurs, improved fuel
consumption is achieved. Torsional damper springs are
provided in the damper and piston assembly to absorb any
engine torque fluctuations during lock-up.

CLUTCH PACKS
There are four clutch packs (refer to figure 4.3). All clutch packs are composed of multiple steel and friction plates.
C1 CLUTCH When applied, this clutch pack allows the input shaft to drive the planet carrier.
This occurs in third and fourth gears.
C2 CLUTCH When applied this clutch pack allows the input shaft to drive the forward sun gear via the 3-4 OWC.
This occurs in all forward gears.
C3 CLUTCH When applied this clutch pack allows the input shaft to drive the reverse sun gear. This only occurs in
reverse gear.
C4 CLUTCH When applied this clutch provides engine braking on overrun. This occurs in Manual 1, 2 and 3 and
also Drive 2 and Drive 3 to prevent objectionable free wheel coasting.

AUTOMATIC TRANSMISSION 5A-45
BANDS
The transmission utilises two bands, the B1 band (sometimes known as the 24 band), and the B2 band (sometimes
known as the low-reverse band). Refer to figure 4.4.
The B1 band is a flexible band which is engaged by the front servo piston. B1 is activated in second and fourth gear.
When activated B1 prevents the reverse sun gear from rotating by holding the C3 clutch assembly stationary. In
second gear only the outer area of the apply piston is utilised. In fourth gear both areas are utilised for greater
clamping force.
The B2 band is a solid band which is engaged by the rear servo piston. B2 is activated in Park,
Reverse, Neutral and Manual 1. When activated B2 prevents the planet carrier assembly from rotating. In Manual 1
only the inner area of the apply piston is utilised. In Park, Reverse and Neutral, both areas are utilised for greater
clamping force.
Figure 4.4- Bands
ONE WAY CLUTCHES
The transmission uses two OWCs, the 1-2 OWC and the 34 OWC. (Note that a third OWC is located in the torque
converter, also known as a sprag.)
The 1-2 OWC is located between the planetary carrier assembly and the centre support. This allows the carrier to
rotate around the centre support in one direction only. The one way clutch is engaged only in Drive 1.
The 3-4 OWC is located between the C4 and the C2 clutch assemblies. This allows the C2 clutch to drive the forward
sun gear in first, second and third gears but unlocks in fourth gear and during overrun.
PLANETARY GEAR SET
The planetary gear set used in the transmission is a conventional six pinion Ravigneaux compound gear set.

PARKING MECHANISM
When Park is selected the manual lever extends the park rod rearwards to engage the parking pawl (refer to (figure
4.5). The pawl will engage the external teeth on the ring gear thus locking the output shaft to the transmission case.
When Park is not selected a return spring holds the parking pawl clear of the output shaft, preventing accidental
engagement of Park.

DIAGNOSIS
DIAGNOSTIC SYSTEM
Recommended Test Equipment and Procedure
The test equipment is designed to be used with the control modules in all vehicles. The components used in the
transmission application are:
l Multi Function Tester, and
l Appropriate vehicle for testing.
Multi Function Tester (MFT)
The MFT is programmed with the special vehicle diagnostic software that allows selection of the unit under test.
The program allows the proper communication to the Transmission Control Unit (TCU).
It then requests information from the user via a menu system to select the required set up.
Examples are viewing codes, clearing error codes, and real-time operation. Set up and operation instructions are
detailed in the user manual.
This equipment can be used by trained personnel such as technicians and mechanics to diagnose electronic and
wiring problems relating to the vehicle transmission. Information that is available includes engine and road (shaft)
speed, transmission oil temperature, throttle position, solenoid/gear status and gear lever position. Current and
stored faults detected by the electronics are also available.

Default Transmission Operating Modes
The TCU relies on accurate information from its inputs and complete control of its outputs to effectively control the
transmission. To ensure that it has both valid inputs and functioning outputs, the TCU carries out both hardware and
software fault detection routines. The TCU will respond to any faults detected by adopting the operating modes which
are detailed below.
The following symptoms of faults are the most obvious results of each fault under ‘normal’ conditions.
There is always the possibility that a fault may not be detected. If undetected fault conditions are present, the
operation of the transmission is difficult to predict.
1 Throttle Fault
l All shifts will occur as if a nominal throttle (approx. 44%) were applied for shift scheduling.
l All shifts will be firm as full throttle and hence high engine torque is assumed.
l The torque converter will be unlocked at all times.
l All downshifts initiated by the shift lever will occur as though they were ‘automatic’ shifts. That is the engine
braking effect will not occur until near the end of the shift.
l Line pressure will always stay high (solenoid 6 OFF) to cope with assumed high throttle/torque.
If a fault is undetected, the percent throttle is most likely to be interpreted as higher than actual, resulting in late
upshifts, early downshifts, firm shifting and a harsh 3-1 shift when stopping.
2 Throttle Not Learnt Fault
The transmission operates from default throttle calibration values which results in the evaluation of the throttle being
higher (more open) than it is. There(ore at zero throttle settings, the transmission may calculate that sufficient throttle
opening is present to justify high line pressure and switch solenoid 6 to OFF.
Other symptoms are:
a. late upshifts and
b. lock-up maintained at zero throttle when the vehicle speed is sufficiently high.
3 Engine Speed Fault
l All shifts will be firm because an engine speed corresponding to peak engine torques is assumed.
If a fault is undetected, the engine speed is likely to be interpreted as stalled resulting in soft shifting possibly with an
end of shift bump.
4 Vehicle Speed Sensor Fault
l All shifts will be controlled by the shift lever with skip downshifts disabled and downshifts only allowed if the
engine speed is low. Fourth gear will be inhibited.
l The torque converter will be unlocked at all times.
If a fault is undetected, the vehicle is likely to be interpreted as being stationary resulting in first gear operation at all
times. Note that speedometer transducer faults are likely to cause the vehicle’s speedometer to become inoperative.
5 Gear Lever Fault (Inhibitor/PRNDL Switch)
l The gear lever is assumed to be in the Drive position.
l The transmission is limited to 2nd,3rd, and R gears only.
l The rear band will apply at all times when the lever is shifted to P, R or N. (B2 inhibition and reverse lockout
protection is disabled.)
l The torque converter will be unlocked at all times.
l Manually (gear lever) initiated downshifts will not be available.
If a fault is undetected, the gear lever position is likely to be interpreted as being higher than actual. Where Park is the
highest position and Manual 1 is the lowest, the result being the availability of higher gears than selected by the gear
lever.
Downloaded from www.Manualslib.com manuals search engine
AUTOMATIC TRANSMISSION 5A-65
If the gear lever is incorrectly adjusted, the transmission may shift gears on bumpy road surfaces.
6
Transmission Oil Temperature Sensing Fault
l All shifts will be firm until the transmission has warmed up, because a high transmission oil temperature is
assumed.
If a fault is undetected, the temperature is likely to be evaluated as being lower than actual, resulting in softer shifts
with ‘end bump’ (very firm feel at the end of the shift).
7
Mode Setting Fault
l All shifts will occur as if the mode is set to ‘NORMAL’.
l The mode indicator will always be off indicating that ‘NORMAL’ mode is selected.
l The mode indicator will not respond to changes in switch setting.
If a fault is undetected, the mode as indicated by the mode indicator is not likely to respond to the mode switch.
8
Battery Voltage Sensing Fault
If the battery voltage is low then shifts to first gear are inhibited.9 the battery voltage is high (>16.5V) then the
transmission goes into limp home (LHM) mode.
If a fault is undetected, the transmission is likely to incorrectly evaluate an ON/OFF solenoid fault resulting in limp
home mode (LHM) operation.
9
ON/OFF Solenoid Fault (Solenoids 1,2,3 and 4)
The transmission adopts its limp home mode (LHM) operation, described above. However, if solenoid 1 is faulty then
the fourth gear LHM strategy will be adopted independent of vehicle speed.
If a fault is undetected, the operation of the transmission is dependent on which solenoid is actually faulty. The
characteristics for different solenoid fault conditions are listed in table 6.1.2.
10 ON/OFF Solenoid Fault (Solenoids 6,7)
If solenoid 6 is found faulty it is always disabled resulting in high line pressure being applied continuously.
If solenoid 7 is found faulty it is disabled resulting in the transmission being locked always.
The transmission does not go into LHM.
11 Variable Pressure Solenoid Fault
The transmission adopts its LHM operation.
If a fault is undetected, the transmission shift feel is likely to be poor for all shifts.
12 Software Fault
The transmission adopts the third gear LHM strategy of operation, independent of vehicle speed. The operation of
the TCU under this condition is difficult to predict. Its operation may be erratic.
If a fault is undetected, the operation of the TCU is likely to be erratic.
13 Power Supply Fault
The transmission adopts the third gear LHM strategy of operation, independent of vehicle speed. If there is an
intermittent power supply connection, the TCU will power-up in fourth gear and then shift to the appropriate gear to
satisfy the conditions present. The power supply is not monitored for fault evaluation.
All faults except for solenoid faults can be recovered without having to turn the TCU off and back on. However, in
general the recovery requires that no faults are present for a period of time (approx. 3 or 30 seconds). Recovery from
a fault will not clear the fault from the keep alive memory
14 Transmission Sump Temperature Exceeding 135°C
l The converter lockup clutch will be applied at lower speeds, causing a shudder through the vehicle.
l The mode indicator will flash in some vehicles.
These faults can be due to the transmission oil overheating or due to an incorrect signal received from the temperature
sensor.

Description / Cause
There have been no faults recorded since the TCU was last cleared. If
the fault history has never been cleared, then there have been no
faults recorded since the TCU was originally powered up.
There is an internal fault within the TCU.
The voltage measured by the TCU corresponding to the battery supply voltage has been outside the range of the maximum operating
voltage of 16.5 volts.
The minimum operating voltage depends on the transmission temperature but is typically between 8-9 V for a warm transmission.
The voltage measured by the TCU from the throttle potentiometer has
Throttle Input Fault
been outside acceptable levels.
This would typically indicate a loose connection in the wiring to, or
within, the throttle sensor which has caused the signal at the TCU to
read 0V or 5V.
Temperature Input Fault The voltage measured by the TCU across the temperature Input terminals has been outside acceptable levels.
This would typically be caused by a loose connection or short to ground
in the wiring to, or within, the temperature sensor which has caused
the signal at the TCU to read 0V or 5V.
The voltage measured by the TCU across the shift lever input termiShift Lever Position
nals has been outside acceptable levels for a significant length of
Input Fault
(Inhibitor/PRNDL Switch) time. This would typically be caused by a loose connection or short to
ground in the wiring to, or within, the inhibitor switch which has caused
the signal at the TCU to read 0V or 5V.
The signal from the ignition, of ignition pulses, has either been nonEngine Speed Sensor
existent or has been unreliable.
Fault
There are two reasons this fault could occur. The first is due to a lack
of ignition pulses when other TCU inputs would indicate that the engine is running, that is the gear lever is in a driving position, the throttle
is applied and vehicle speed increasing.
The second cause of this (aunt is the frequency of the pulses of the
ignition pulse input to the TCU indicate an unachievable engine speed.
The pulses from the shaft speed sensor have either been non-exisShaft Speed Sensor
tent or have been unreliable.
Fault
There are three reasons this fault could occur. The first is due to a
(Speedo Sensor)
sudden loss of speedometer pulses at a time when they were fre quent,
thus indicating an unachievable degree of deceleration of the drive
line. The second cause of this fault is that the frequency of the pulses
on the shaft speed sensor input to the TCU indicate an unachievable
propeller shaft speed. The third is the presence of a high engine speed
in a driving gear with no speedometer pulses.

Description / Cause
The signal from the mode switch is unreliable.
This fault is caused by too many changes in the mode input signal
over a period of time. Typical causes would be an intermittent connec
tion in the switch or wiring or an intermittent short to ground in the
wiring.
The data link between the TCU and the engine management module
is found to be unreliable because the checksum, or the data received,
did not match the correct checksum.
This could be caused by an open circuit, short circuit to ground or a
loose connection in the link wire itself.
Each solenoid in turn is switched off if it was energised, or switched on
if it was not energised by a very small 100 ms pulse. This pulse is too
short for the solenoid to react so transmission operation is not af
fected.
The solenoid feedback voltage is measured before the 100 ms pulse
and again during the pulse. If the difference is outside the acceptable
limits the relevant fault messages are set.
Typical causes would be an open circuit in the wiring to or within the
solenoid, or a short circuit to ground in the wiring to, from or within the
solenoid in question.
If several of these fault codes are presents check the wiring or
connectors that are common to the selected solenoids, especially the
earth connections.
The state of the solenoid feedback voltage is outside acceptable
limits but the faulty solenoid could not be isolated.
The current to solenoid 5 was outside acceptable limits.
This fault results from a mismatch between the current set point for
solenoid 5 and the current measured by the feedback within the TCU.
Typical causes would be an open circuit or short circuit to ground in
the wiring to, from or within the solenoid. It is also possible that there
has been a fault in the solenoid output circuit. If this is the case
however, the fault should be continually present.
The closed throttle position has not been learnt. This fault
may be caused by the transmission not having reached normal
operating temperature or the engine idle speed being incorrect.
The TCU will learn the closed throttle position automatically
when the transmission is brought to normal operating
temperature and the engine is allowed to idle in Drive with the
‘base idle’ correctly set and the air conditioner (if fitted)
switched off.
AUTOMATIC TRANSMISSION 5A-69
MECHANICAL TESTS
In Vehicle Transmission Checks
Carry out the following tests before removing the transmission.
l See Checking Transmission Fluid Level, Section 7.2.1.
l Check that the transmission oil is not burnt (colour and smell are correct).
l Ensure that the transmission is not in limp home mode (LHM).
l Check that the battery terminals and the earth connections are not corroded or loose.
l Check the engine stall speed is within the handbook value.
l Check that the cooler flow is not restricted.
l Check that all electrical plug connections are tight.
l Carry out a road test to confirm the symptoms, if necessary.
l Inspect the oil, ensure that there are no metal or other contaminants in the oil pan.
Diagnosing Oil Leaks
Determine the source of oil leaks by firstly cleaning down the affected area, then driving the vehicle.
Inspect the seals to confirm the source of the leak.
l To determine the source of a rear servo oil leak, raise the vehicle on a hoist, then carry out a reverse stall.
l To determine the source of a front servo leak, raise the vehicle on a hoist, then run the vehicle in second gear.

ADJUSTMENTS
HYDRAULIC SYSTEM
The procedures detailed below should be followed in the event that the self test procedure detailed in section 6, or a
defect symptom, indicates that there is a fault in the hydraulic system.
When making adjustments to the transmission, select the appropriate procedures from the following preliminary
checks.
l Conduct a transmission fluid test procedure, refer to section 7.2.
l Check the manual linkage adjustment (refer to the vehicle workshop manual).
l Check engine idle speed (refer to Section 7.3).
l Conduct a stall test (it is outside the scope of this publication to detail this procedure)
l conduct a road test (it is outside the scope of this publication to detail this procedure).
TRANSMISSION FLUID TEST PROCEDURE
Checking Transmission Fluid Level
This procedure is to be used when checking a concern with the fluid level in a vehicle. A low fluid level will result in
gearshift loss or delay if driven when the vehicle is cold.
The vehicle is first checked for transmission diagnostic messages (refer to section 6). If the vehicle has a speedo fault
it is possible for the oil level to be low.
The vehicle is to be test driven to determine if there is an abnormal delay when selecting drive or reverse, or loss of
drive. One symptom of low oil level is a momentary loss of drive when driving the vehicle around a comer. Also when
the transmission fluid level is low, a loss of drive may occur when the transmission oil temperature is low.
If there is no loss of drive when the vehicle is driven warm and a speedo fault is registered, then fluid should be added
to the transmission.
Checking, Adding Fluid and Filling
When adding or changing transmission oil use only Castrol TQ 95 automatic transmission fluid (ATF) or other approved
fluids. The use of incorrect oil will cause the performance and durability of the transmission to be severely degraded.
Do not underfill the transmission. Incorrect tilling may cause damage to the transmission. The fluid level setting
procedure is detailed below.
Notice
When a transmission is at operating temperature hot transmission fluid may come out of the case if the fill plug is
removed. 9 the transmission is at operating temperature allow two hours for cooling prior to removing the plug.
1. If the vehicle is at operating temperature allow the vehicle to cool down for two, but no greater than four hours
before adding transmission fluid (this will allow the transmission to be within the correct temperature
range).
While hot the ATF level is higher and removing the plug may result in oil being expelled from the filler hole. This
will result in the level being low.
2. The transmission selector is to be in Park.
Switch the engine off.
3. Raise the vehicle on a hoist (or leave over a service pit).
4. Clean all dirt from around the service fill plug prior to removing the plug. Remove the oil service fill plug.
Clean the fill plug and check that there is no damage to the ‘O’ ring.
Install the filler pump into the filler hole.
5. Lower the vehicle with the filler pump still connected and partially fill the transmission.
Start the vehicle in Park with the Parking brake and foot brake applied with the engine idling, cycle the transmission
gear selector through all positions, adding ATF until gear application is felt.
Downloaded from www.Manualslib.com manuals search engine
5A-80 AUTOMATIC TRANSMISSION
6. Switch off the engine and raise the vehicle on the hoist, if applicable, ensuring that the vehicle is level.
7. Three minutes after the engine has stopped, but no longer than one hour, remove the filler pump, The correct
level is reached when ATF is aligned with the bottom of the filler hole. If the correct level is not reached, then add
a small quantity of ATF to the correct level.
8. Replace the transmission filler plug and clean all remnants of ATF on the transmission and vehicle.
9. Tighten the transmission filler plug to specification.
Checking, Adding Fluid and Filling - Drained or Dry Transmission
To set the correct fluid level proceed as follows.
1. Set the transmission selector to Park and switch the engine off.
2. Raise the vehicle on a hoist (or leave over a service pit).
3. Clean all dirt from around the service fill plug prior to removing the plug, Remove the oil service fill plug. Clean the
fill plug and check that there is no damage to the ‘O’ ring. Install the filler pump into the filler hole.
4. Lower the vehicle with the filler pump still connected and partially fill the transmission. This typically requires
approximately :
a. If the transmission torque converter is empty:
9.0 litres - 4WD
9.0 litres - RWD
b. If the transmission torque converter is full:
4.5 litres - 4WD
4.5 litres - RWD
5. Start the vehicle in Park with the Parking brake and foot brake applied with the engine idling, cycle the transmission
gear selector through all positions, adding ATF until gear application is felt.
6. Then add an additional 0.5 litres of ATF.
7. Switch off the engine and raise the vehicle on the hoist. Remove the filler pump and replace the filler plug. The
plug shall be tightened to specification.
8. The vehicle is then to be driven between 3.5 and 4.5 kilometers at light throttle so that the engine does not
exceed 2500 rpm. This should result in the transmission temperature being in the range 50 to 60°C.
9. With the engine idling, cycle the transmission selector through all gear positions with the brake applied.
10. Stop the engine. Raise the vehicle on the hoist, if applicable ensuring the vehicle is level.
11. Three minutes after the engine has stopped, but no longer than one hour, remove the filler plug. The correct
level is reached when ATF is aligned with the bottom of the filler hole. If the correct level is not reached, then add
a small quantity of ATP to the correct level.
12. Replace the transmission filler plug and clean all remnants of ATF on the transmission and vehicle. Tighten the
transmission Filler plug to specification.

Carry out the adjustments to the idle speed as detailed in the workshop manual.
Throttle Position Calibration
Should the throttle position data stored in the TCU be lost or be out of specification, as indicated by a diagnostic
trouble message, it may be re-established by the following procedure.
l Check that the hot engine idle speed is within specification.
l Allow the engine to idle in ‘Drive’ for 60 seconds with the air conditioner (if fitted) turned off. The closed throttle
reference point in the TCU has now been set.
Switch the engine off but leave the ignition on. Hold the accelerator pedal on the floor for 60 seconds. The wide open

REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings
are to be noted.
l Ensure that, before replacing a transmission the cooler
lines are flushed out to remove any debris. This can be
done by applying compressed air to the rear cooler line
forcing oil and any contaminants out of the front cooler
line.
l The cooler flow should be checked after the transmission
has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure
the flow over 15 seconds with the vehicle idling in park.
l The flow rate should exceed 1 liter in 15 seconds.
l Be wary of any situation where water enters the
transmission. This may result in fluid foaming and leaking
through the breather.
l Ensure that both earth straps (one at the batted terminal
and one on the vehicle body) are connected in the

chipping of the transfer case.
1. Using cleaning solvent, clean the residual oil and dirt
deposits.
Notice
During cleaning, be careful not to damage the metal
surfaces.
2. After cleaning, dry the parts with low pressure (Max. 20 psi)
compressed air.
3. Lubricate the ball bearings and needle bearings with transfer
case oil after cleaning.
Notice
Protect the lubricated bearings from dust.
Inspection Procedure
1. Visually check the all removed parts.
Notice
Always replace the hose coupling, O-ring and oil seal with
new parts.
2. Inspection Terms
l Burr : Local rise of material forming protruding sharp
edge
l Chip : An area from which a small fragment has been
broken off or cut
l Crack : Surface break of line nature indicating partial or
complete separation of material.
l Excessive wear : Heavy or obvious wear beyond
expectations considering conditions of operation.
l Indentation : Displacement of material caused by localized
heavy contact.
l Galling : Breakdown of metal surface due to excessive
friction between parts. Particles of the softer material
are torn loose and welded to the harder material.
l Nick : Local break or notch, usually displacement of
material rather than loss.
l Scoring : Tear or break in metal surface from contact
under abnormal pressure.
l Step wear : Heavy wear that produces a step that can
be seen or felt between adjacent contact and noncontact
surfaces.
l Uneven wear : Condition of localized, unevenly distributed
wear Includes hollows, shiny spots, uneven polish and
other visual indications.

FUNCTION DESCRIPTION
l
TOD System Select Mode (4H and 4L)
4H is the mode when drive normally of which gear ratio is 1:1 and 4L mode distributes power to front and rear
wheels 50:50 of which gear ratio is 2.48:1.
l
TOD System Function (select 4H mode)
TOD system controls clutch mechanism to comply with rotation in front and rear propeller shaft and if its difference
exceeds the permissible range, corresponding power is distributed into front wheel through EMC (Electro-Magnetic
Clutch).
Hall effect sensor signals speed on front and rear propeller shafts going through with TOD control unit.
Transfercase clutch coil is activated by variable current on exceeding difference of speed in front and rear propeller
shafts.
l
Function of 4L Mode
When select 4L mode, EMC is locked to apply maximum torque into front and rear propeller shafts. Shift motor
rotates also 4L position by rotation of cam thus propeller shaft torque changes from 1:1 to 2.48:1 by planetary
gear set.
l
Shift Motor
It locates backside transfer case, which drives rotary helical cam.
When mode select switch changes to 4L, shift fork is on position for 2.48:1 by rotation of helical cam.
l
Transfer Case
TOD transfer case distributes power into front and rear axle by operation of 4H/4L switch and shift motor.
Shifting 4H to 4L, is performed towards reducing HI-LO collar by means for connection HI-LO shift fork with
output shaft in order to join with planetary gear. Torque transmits input shaft then sun gear rotating front planetary
gear. Front planetary gear join with output shaft and drives LO position.

5D2-10 TRANSFER CASE (TOD)
Electric Shift System Operation
The Electric Shift System is responsible for changing the Transfer Case gear ratio by controlling the electric shift
motor. The TCCU monitors the 4H/4L switch, neutral switch, speed sensors, position encoder, and ignition switch.
A range change is initiated when
1. The 4H/4L Switch is changed from 4H to 4L or from 4L to 4H.
2. The motor position (as indicated by the position encoder) does not match the 4H/4L Switch immediately after the
ignition is turned on.
1. Shift Criteria
When a range change is initiated a Diagnostic Test will be completed on the motor, speed sensors, and position
encoder. If the Diagnostic Test fails, the shift will not be attempted. If all components are operating properly, the
TCCU will attempt a range change after the following shift criteria are met:
a. The transmission is in neutral for 2 seconds after the shift is requested.
b. Both propshaft speeds are below 87 rpm (2580 pulses/minute).
If the transmission is taken out of neutral before 2 seconds has elapsed, or either propshaft speed increases
above the limit, the shift will be suspended and the 4L Indicator will continue to blink until the criteria are met again
or the 4H/4L Switch is returned to the original position.
2. Range Change
When the shift criteria are met, the motor is rotated in the appropriate direction (as determined by the selector
switch) until one of the following occurs:
a. The motor reaches its destination.
b. The motor is on for 5 seconds without reaching its destination. The shift has failed and the TCCU will respond
as default mode.
c. A fault occurs with either the motor or position encoder. Refer to the diagnosis requirement.
When the motor is energized, the Ignition, 4H/4L Switch, propshaft speeds, and transmission neutral inputs are
ignored.
3. Indicator Function
Once a range change has been initiated the 4L Indicator will begin to blink at a rate of 0.3 seconds on, 0.3
seconds off until the shift is completed or canceled.
If a successful shift has been completed, the 4L Indicator will be illuminated if the motor is in Low and it will be
turned off if the motor is in High.
4L Indicator illuminates as below figure.

·4L ® 4H

Downloaded from www.Manualslib.com manuals search engine
TRANSFER CASE (TOD) 5D2-11
4. Electric Shift Default Mode
If the motor fails to reach its destination, the TCCU will attempt the following (in order):
a. The TCCU will wait 3 seconds then attempt the shift again.
b. If the second attempt to reach the destination fails the TCCU will wait 3 seconds then attempt to rotate the
motor back to the original position. If successful, all future shifts will be inhibited until the Ignition is cycled.
c. If the attempt to return to the original position fails, the TCCU will wait 3 seconds then attempt to rotate the
motor to the original position again. If the second attempt to return to the original position is successful, the
“4WD CHECK” lamp will be illuminated, and all future shifts will be inhibited until the Ignition is cycled.
d. If the second attempt to return to the original position fails the motor will be turned off, the “4WD CHECK” lamp
will be illuminated, and all future shifts will be inhibited until the Ignition is cycled.
TODTM System Operation
The TODTM System is responsible for distributing torque between the front and rear axles. The TCCU monitors the
propshaft speeds, operating range (High/Low), and ABS activity and then applies a calculated amount of torque to
the front axle by Pulse Width Modulating the current applied to the EMC.
1. Touch-off Torque
The minimum EMC Duty Cycle is based on the vehicle speed and throttle position
The TCCU receives the TPS signal from the following sources:
On vehicles equipped with CAN, the TCCU receives the TPS signal from the CAN bus.
2. When Slip Detection
The TCCU continuously monitors the front and rear propshaft speeds to detect wheel slip.
3. Wheel Slip Control
When wheel slip is detected the TCCU controls the EMC duty cycle as necessary until the wheel slip is reduced
below the allowable limit. The EMC Duty Cycle will then be reduced to the Touch-Off value.
4. Brake/ABS Strategy
When the ABS System is active, the EMC Duty Cycle is set to a fixed duty cycle (30%) to aid in braking without
counteracting the ABS System.
5. 4L Strategy
When the system is operating in 4L, the TCCU continues TODTM (operation provided that the propshaft speed is
below 175 rpm (5220 pulses/minute)). When the speed increases above 175 rpm, the EMC Duty Cycle is set to
the maximum value (88%) which applies the maximum available torque to the front axle.

DIAGNOSIS
While the TCCU is active it periodically monitors its inputs and outputs. If a fault is detected the “4WD CHECK” lamp
is illuminated and a fault code is stored in the TCCU memory.
When requested, fault codes are downloaded to a diagnostic connector (K-line) serial communications using SCAN100.
DIAGNOSTIC TESTS
1.TCCU Internal Function
When the Ignition is turned on the TCCU tests its ROM and RAM. If there is a fault, the TCCU immediately resets
itself and re-tests the ROM and RAM. If the fault persists the TCCU continues to reset and re-test until the fault is
corrected or the ignition is turned off. All TCCU functions are inhibited until the fault is corrected. The “4WD
CHECK” lamp is not illuminated if there is a ROM or RAM fault.
If the ROM/RAM passes the EEPROM memory is tested. If there is a fault the “4WD CHECK” lamp is illuminated
and the TCCU continues to operate using the default calibration data stored in ROM. Fault codes are not stored
when there is an EEPROM fault.
An EEPROM fault can only be cleared by cycling ignition off-on.
2.Shift Motor Assembly Test
If the TCCU detects a shift motor or position encoder fault continuously for one second the ‘4WD CHECK” lamp is
turned on and the appropriate fault code is stored in memory.
a. A shift motor fault when the motor is off is defined as follows:
Motor H-L shorted to Ground
Motor L-H shorted to Ground
Motor open circuit
b. A shift motor fault when the motor is energized is defined as follows:
Motor H-L shorted to Ground
Motor L-H shorted to Ground
Motor H-L shorted to Motor L-H
Motor open circuit
c. A position encoder fault is defined as follows:
Any position code which does not correspond to the valid 9 codes.
A short to ground on any of the encoder lines.
d. If no shifts are in progress when a failure occurs the TCCU will not respond to any shift commands.
e. If a shift command has been received, but not acted upon when a failure occurs the TCCU will cancel the
command and not respond to any subsequent shift commands.
f. If a shift command is in progress when an invalid position code is confirmed it will be halted and the TCCU will
turn the motor toward the high position. Afterwards the TCCU will not respond to any shift commands.
Downloaded from www.Manualslib.com manuals search engine
5D2-16 TRANSFER CASE (TOD)
g. If the shift motor/position encoder assembly failure (other than a motor failure which occurs when the motor is
energized) recovers continuously for one second the TCCU will function normally. The “4WD CHECK” lamp is
turned off but the fault code will remain in memory.
h. A motor failure (i.e. open or short circuit) which occurs when the motor is energized can only be cleared by
cycling the ignition off-on.
3. Front Speed Sensor Test
If a Front Speed Sensor fault is detected continuously for 0.5 second the “4WD CHECK” lamp is illuminated. The
TCCU then responds as follows:
a. If the system is in High Range the TCCU uses the Rear Speed Sensor to determine the EMC Touch Off level
and wheel slip control is suspended.
b. If the system is in Low Range, the EMC Duty Cycle is set to maximum (independent of vehicle speed) until the
system is shifted out of 4L.
c. All Electric Shift activity is halted until the Ignition is cycled. If a shift is in progress it will be completed.
If the Front Speed Sensor recovers continuously for O.5 second the TCCU will function normally. The “4WD
CHECK” lamp is turned off but the fault code will remain in memory.
4. Rear Speed Sensor Test
If a Rear Speed Sensor fault is detected continuously for 0.5 second the “4WD CHECK” lamp is illuminated. The
TCCU then responds as follows:
a. If the system is in High Range the TCCU uses the Front Speed Sensor to determine the EMC Touch Off level
and wheel slip control is suspended.
b. If the system is in Low Range, the EMC Duty Cycle is set to maximum (independent of vehicle speed) until the
system is shifted out of 4L.
c. All Electric Shift activity is halted until the Ignition is cycled. If a shift is in progress it will be completed.
If the Rear Speed Sensor recovers continuously for 0.5 second the TCCU will function normally. The “4WD
CHECK” lamp is turned off but the fault code will remain in memory.
5. Both Speed Sensor Faulty
If both the Front and Rear Speed Sensors are faulty continuously for 0.5 seconds the “4WD CHECK” lamp is
illuminated. The TCCU then responds as follows:
a. If the system is in High Range the TCCU sets the EMC Touch Off level based on a vehicle speed of 0 and wheel
slip control is suspended.
b. If the system is in Low Range, the EMC Duty Cycle is set to maximum until the system is shifted out of 4L.
c. All Electric Shift activity is halted until the Ignition is cycled. If a shift is in progress it will be completed.
If both Speed Sensors recover continuously for 0.5 second the TCCU will function normally. The “4WD CHECK”
lamp is turned off but the fault code will remain in memory.
6. EMC Test
The EMC is tested for open circuit or short circuit to ground. If a fault is detected continuously for 0.8 second the
“4WD CHECK” lamp is turned on and all TODTM activity is halted.
If the EMC recovers continuously for 0.8 second the TCCU will function normally. The “4WD CHECK” lamp is
turned off but the fault code will remain in memory.

DIAGNOSTIC TROUBLE CODES
(DTC’S)
1. Diagnostic Trouble Code Retention
The first time a fault is detected a DTC is stored in the TCCU’s
Non-Volatile memory. This DTC will remain in memory until
the TCCU is instructed to erase DTC’s by SCAN-100. DTC’s
will not be erased by disconnecting power to the TCCU.
