Fault finding - System operation
The main functions of ABS on this vehicle are the electronic balancing of front and rear braking by controlling rear
wheel slip and preventing the brakes from locking by controlling the slipping of all four wheels.
The system also supplies the other computers with information on the vehicle speed via a wire connection for the
discharge bulbs, the radio and the electric sunroof, and via the multiplex network for the other computers. The ABS
computer supplies the multiplex network with the odometry for the instrument panel and navigation system. If heavy
braking produces very rapid deceleration, the ABS computer sends out a request to the UCH via the multiplex network
to ask it to switch on the hazard warning lights (depending on the law in the relevant country).

NOTESSpecial notes:
This fault does not cause illumination of any warning lights, nor does it generate any
fault message.
Conditions for applying the fault finding procedure to stored faults:
Clear the stored fault, carry out a road test at a speed of > 37 mph (60 km/h) and test
the brakes using ABS.
Check the conformity of the brake light bulbs.
Using the diagnostic tool, check on the statuses screen that ET017 Brake pedal displays the pressed and released
positions of the brake pedal correctly.
If the correct pedal position is not displayed, use the interpretation of ET017.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
