Introduction
With DIAG++ you can use a standard personal computer to read and delete diagnostic codes, program vehicle
parameters and end of line test (EOLT) for Haldex EB+ 4.0 EBS (referred as EBS in the rest of the document). The
USB PC Interface (dongle) allows communications between a standard PC and the EBS ECU. Connections to the
USB PC Interface (dongle) are made through a cable connecting to a USB port on the computer and another
cable connecting the diagnostic interface to the ECU. The vehicle parameter data is stored inside the ECU. It will
remain intact even after electrical power is removed from the EBS.
Note: The USB PC Interface (dongle) is different to the RS232 interface pods as used on earlier systems.

Connecting a PC directly to EB+ 4.0
To access the ECU directly, connect one end of the USB
cable (042707309) into a USB port on the back of your
PC or laptop and the other end into the PC Interface
(815023001).Then connect the PC Interface to either
T-CAN or H-CAN connector on the EB+ 4.0 using cable
series 844 511 xxx.
The LED light on the PC Interface should now be ‘on’,
coloured orange
Power the EB+ 4.0 EBS from an external 24 V dc supply
(i.e. correctly rectified and smoothed) or a tractor unit.
The LED light on the PC Interface should now be ‘on’,
coloured red.
If it is not, please check your connections and try again.

Connecting to EB+ 4.0 via ISO 7638
The ECU can be accessed by using the EB+ ISO diag-
nostic cable (815018001).
Disconnect the ISO 7638 truck to trailer cable and
connect the EB+ ISO diagnostic cable (815018001)
between the truck and trailer.
Connect the PC Interface to the ISO diagnostic cable

Starting DIAG++
Connect the USB dongle to the PC
Click on the DIAG++ short cut to start the programme.
If the security warning is displayed click on the run icon
to start DIAG++
The dongle is provided with a multi function LED to confirm correct function of the unit as follows:
Orange: Indicates connection to USB port
Red: Indicates connection to USB and EB+ 4.0 EBS
Green: Indicates data is being transmitted
Power up the ECU. During the self check procedure the
system displays the following functions:
the trailer EBS warning light comes ‘on’ and stays ‘on’.
One audible cycle is produced by the EPRV’s
(EBS valves).
At the same time the LED on the USB dongle
will illuminate ‘red / green’ to show that it is
communicating with the ECU.
The EBS layout schematic should now be showing in
the browser window.
If no EBS layout is shown, click on the binoculars to
auto search for the correct PC connection port.
