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.

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.
The powering of the system is via :
ISO7638- 7 Pin - Full EBS function Fig 2.
The EB+ Gen 2 system can also be powered via :
ISO7638- 5 Pin - (No CAN data bus) ABS + ELS function only Fig 3.

As a safety back-up ISO1185 (24N) - Stop Light powering provides

The ISO7638 controls a Trailer warning device in the driver’s console .
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

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.
For further information on EB+ Gen 2 Info Centre see user guide
(000 700 270).
The EB+ Gen 2 Info Centre provides a multi-digit display of:
Information:
• Read Diagnostic Trouble Code (DTC)
• Clear DTC
• Conguration
• ECU software version number
• ECU serial number
• Vehicle Ident Number (VIN)
• Manufacturer OEM
• Info Centre software version number

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.
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.
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.
This information is described visually in Fig 14 on page 11.
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).
The push-through condition is cancelled on vehicle movement above
10 km/h returning the system to load sensing operation.
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.
This condition is cancelled on vehicle movement above 10 km/h
returning the system to load sensing operation.

This lamp sequence relates to:
1. Service due - indicates that trailer or system service distance is
due. After servicing the trailer or system the next service distance
must be reset by using the Info Centre or EOLT program.
2. NON EB+ fault - A fault with a device connected to the EB+ but
not directly effecting the EB+, for example: Reset-to-Ride valve
(COLAS®).
