General Information
21
Your trailer has been fitted with the latest technology Haldex Electronic
Braking System EB+ Gen 2. This system has been specifically designed to
be effective, reliable and easy to service. The purpose of this booklet is to
describe the components involved and give you sufficient information to
make your use of the system easy.
Concept
EB+ Gen2 = Antilock Brake System (ABS)
+ Electronic Load Sensing (ELS)
+ CAN (Controller area network ISO11992 data link - computer data from
and to the towing vehicle)
The system reacts to electrical or pneumatic signal from the towing
vehicle. It electronically processes those signals plus signals received from
other sensors on the trailer. In response to those signals the EB+Gen 2
regulates pressure to the brake chambers.
System Description
The position of the various components is shown in Tri-axle layout, Fig 1.
The system is equally compatible with single and tandem axles.
The EB+ Gen 2 system is an integrated construction of an encapsulated
Electronic Control Unit (ECU), Electro pneumatic relay valves (EPRV’s),
over moulded connectors, integrated pressure transducers and a flash
upgradable program memory.
Onset of braking is denoted by presence of a demand on the ISO11992
data link (CAN) via the ISO7638 connector. Driver demand pressure is then
determined electronically either by the data link or control line pressure
transducer within the EPRV’s assembly.
The demand pressure is then modified using data from the air suspension
(Electronic Load Sensing), and may be further modified when a wheel
speed sensor detects imminent locking of the sensed wheels (ABS).
The output to the brakes is exercised by the ECU control of the EPRV’s see
Fig 2.
The EB+ Gen2 ECU also provides up to 5 auxilliary functions such as
automatic reset-to-ride height (COLAS®), lift axle control (ILAS®-E), retarder
and Stability control.
EB+ Gen 2 incorporates an odometer facility which measures total distance
of the trailer and its read-out is shown on an optional EB+ Info Centre unit
(Only when powered by the ISO7638 cable).
The EB+ Info Centre is a side of trailer mounted unit used also for read-out
of diagnostic codes and other information available from the EB+ Gen 2
ECU.
The EB+ Gen 2 also incorporates an enhanced information storage and
retrieval facility.
For the fleet operator, a ‘Fleet Log Reader’ allows the compilation of a full
history of each trailer or long term monitoring.
For the trailer manufacturer, an ‘End-of-line’ Testing (EOLT) to confirm
correct performance of the EB+ Gen 2 system.

System Layout
The system fitted to your trailer may have 2 or 4 Sensors and 2
Modulators (EPRV's). The variants available being 2S/2M and 4S/2M.
As a safety back-up ISO1185 (24N) - Stop Light powering provides ABS
function Fig 4.
The powering of the system is via :
ISO7638- 7 Pin - Full EBS function Fig 2.
The ISO7638 controls a Trailer warning device in the driver’s console .
The EB+ Gen 2 system can also be powered via :
ISO7638- 5 Pin - (No CAN data bus) ABS + ELS function only Fig 3.
The warning device has two functions:
• To indicate system integrity via the correct sequence (see Figs 10 and 11
on page 10) every time the EB+ Gen 2 ECU is electrically powered up.
• To indicate by a permanent display, when the vehicle is moving, if a fault
has been detected.
The layout of the chassis components are shown in Fig 5

System Diagnostics
An important feature of the EB+ Gen 2 system is that it provides an
extensive on board diagnostic capability. The system displays a range of
codes, which allow rapid diagnosis of the problem should one occur.
Diagnostic communication is in accordance to ISO11898 using Keyword
(KWP2000) protocol and is accessed by either the ISO7638 - 7 pin
connector which uses pin 6 and 7 as a CAN data bus using ISO Interface
Assembly (815 018 001) or optional side-of-vehicle connector or directly to
ECU (Fig 7). Any suitable device connected to this CAN data bus may read
diagnostic information.
An EB+ Gen 2 Info Centre can be connected permanently to the ECU's
diagnostic 'DIAG' connection. While the ECU is powered information is
transferred to the Info Centre's memory, which can be recalled. Power is
supplied from the vehicle system via the ECU diagnostics connector.

Warning Device, System Check Procedure and Power-Up Modes
Warning Device
The warning device function depends on the ISO7638 power supply used:
A warning device located on the driver's console of the towing vehicle
is operated from the ISO7638 power cable only when the EB+ Gen 2 is
powered by the ignition switch. (Fig 9)
Note: If a dedicated power source is unavailable to the EB+ Gen 2 from the
ISO7638 connector then system integrity will not be indicated by the cab
mounted warning device.
As an option to the cab warning device a trailer mounted warning lamp
may be provided as an auxiliary function. This lamp mimics the signal
to the cab warning device but will only function if the ISO7638 power is
connected.
Fig 9
2 sec.
Note: The signal produced may be different to that produced by the cab
device due to possible modification of the cab device by the towing
vehicle.
System Check Procedure
1. On power up of the system, the warning device must indicate one of
the following sequences in order to show a fault-free system:
OPTION 'A' - (Fig 10)
OPTION 'B' - (Fig 11)
2. During the self-check procedure, the system cycles the EPRV's. With foot
brake applied one exhaust of air from each EPRV will be audible.
ON
OFF
Fig 10
Option A
ON for 2 seconds
Warning device OK and system self-checking.
OFF
System self-checked (not sensors)
Once these two checks are made with correct results, no further checks
are required.
If the results are not satisfactory, Haldex DIAG+ or EB+ Info Centre should
be used to establish the diagnosis.

@ 10 km/h
Power Up Modes
The EB+ Gen 2 system has two power up modes. With switching the
Ignition on (B+ applied) the following occurs:
With no yellow line pneumatic pressure (i.e. Brakes OFF)
The system adopts load sensing mode when the brakes are applied. This
load sensing mode is limited to 2 minutes for any single brake application,
after which it returns to a push-through condition (approx 1:1).
ON
OFF
Fig 11
The push-through condition is cancelled on vehicle movement above 10
km/h returning the system to load sensing operation.
Option B
ON for 2 seconds
Warning device OK and system self-checking.
With yellow line pneumatic pressure (i.e. Brakes ON) (Park on air)
Apply foot brake, switch Ignition On.
The system adopts a push-through (approx 1:1) condition. When the
brakes are released and re-applied the system remains in push-through
unless the brakes are released for longer than 2 minutes, after which it
returns to load sensing operation.
OFF for 2 seconds
System self-checked and preparing to check
sensors.
ON until moving
System waiting for vehicle to move above 10 km/h
in order to check that the sensors are working.
OFF
Once the vehicle is moving above 10 km/h
and the warning device clears, the electronic
system is fully checked.
This condition is cancelled on vehicle movement above 10 km/h returning
the system to load sensing operation.

General Information
Braking with EB+ Gen 2
Soft Docking
In an emergency apply full force on the brake pedal. The EB+ Gen 2 will
be activated immediately when you fully apply the brakes and will assist
you to retain steering control of your vehicle according to the road surface
conditions.
Soft Docking, when linked to the Haldex EB+/EB+ Gen 2 system will apply
brakes automatically when reversing into a loading bay. The system will
reduce vehicle speed to prevent significant damage to the vehicle and
the dock by timely application of the brake pressure when reversing.
The braking is indicated by sensing of 1 meter distance and wheel speed
sensing. The EB+ / EB+ Gen 2 system will then command the brake apply.
DO NOT apply and release the brakes by pumping the brake. This is
known as 'Cadence braking' and can have a detrimental effect on
vehicle braking.
Lining Wear Sensing (LWS)
EB+ Gen 2 Lining wear is a device that allows multiple lining wear
indicators (LWI) to be connected to a single analogue input ‘AUX 4’ on the
EB+ Gen 2 ECU. EB+ Gen 2 Lining wear device can be installed on all types
of towed vehicles were provisions are made in the brake pads. The product
provides lining wear indication, without the need to remove wheels as
required on disc brakes, via the EB+ Gen 2 diagnostic tools Info Centre or
DIAG+.
Info Point
With an illuminated spot the Info Point will instantly show if the trailer has
a fault in the braking system. The Info Point connects to EB+/EB+ Gen 2
Auxiliary. It is dedicated to alert fault in Lining Wear, Sensors, Colas etc. It is
ADR approved.
The device connects to specified sensors from the brake pads and when
a brake lining has reached its wear limit the sensor signals the EB+ Gen 2
Lining wear device which activates the EBS warning lamp indicating a fault.
EB+ Gen 2 Stability
EB+ Gen 2 Stability is an advanced Trailer Roll Stability function that senses
when the trailer is near to a rollover condition and automatically applies
the trailer brakes to slow the vehicle combination down.
It will help to reduce the likelihood of trailer rollover BUT IT WILL NOT
PREVENT ROLLOVER and should be used as an aid to normal good
driving practice. The stability function is a SAFETY BACK UP system the
same as anti-lock braking function.
It uses a lateral accelerometer to determine the level of cornering and
as part of its operation it applies brief pulses of brake pressure during
normal cornering, even below a level at which a rollover may occur.
These pulses may be noticeable to a driver but will reduce in number after
the system has learnt the vehicle combinations roll characteristics and are
part of the normal operation. This learning process will be repeated every
ignition cycle, if the load is changed or if an axle is lifted or lowered.
Traction Assist using ILAS®-E
Traction assist is made operative by a 24v (constant or intermittent) supply
to the yellow wire in the 3 core auxiliary cable connected to AUX 2 or AUX
3 and programmed as ILAS-E Front. On request for traction assist, front axle
lifts.
The front axle drops when either:
• The vehicle speed exceeds 30kph or
• The suspension pressure reaches more than 130 % of the laden bag
pressure
