NOTESSpecial notes:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. The
ABS/ESP system is not faulty, but has received unusable signals from the automatic
transmission. Run fault finding on the automatic transmission with the diagnostic tool.
Note:
The automatic transmission does not always store these transient faults as quickly as
the ABS/ESP.
If there is no stored fault in the automatic transmission computer memory, start the
engine, and if no present fault is displayed, contact the Techline. Once the fault in the
automatic transmission has been repaired, clear the ABS/ESP computer fault memory.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after starting the engine.
Using the diagnostic tool, check in the parameter screen that the PR063 Vehicle parameters truly correspond with
the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Carry out a multiplex network test and check the automatic transmission system using
the diagnostic tool.
If the fault is still present, contact the Techline.
Use command VP004 Vehicle parameters to define the appropriate parameters for the
vehicle type.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a new test with the diagnostic
tool.
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.

COMMAND (continued)
SPECIAL COMMANDSAC195:Vehicle speed signal.
This command sends a speed other than 0 mph on the computer's vehicle speed wire output
(Track 33) to users of that signal (xenon bulbs, radio, sunroof).
Note:
This command has no visible effect on the dashboard speedometer needle.
Xenon bulbs: Switch on the dipped headlights and run command AC195. You should see a slight
change in the height of the headlight beam (depending on vehicle speed, the height of the beam is
adjusted to improve visibility).
–Radio: switch on the radio and check that the speed-dependent volume control function is active.
Run command AC195. During the command, you should notice the volume of the sound increase
and then decrease.
–Sunroof: this command has no visible effect on the sunroof. This command changes the activation
threshold of the anti-pinch system (the pressure exerted by the sunroof varies with vehicle speed
due to aerodynamic factors).
AC196:Request to switch on hazard warning lights.
This command sends the UCH a request to switch on the hazard warning lights to test their operation
during emergency braking (depending on UCH configuration).
SC001: Check target teeth.
This command tests the condition of the teeth on each wheel. Select command SC001 Test target
teeth. The test result should show 48 teeth.
SC006: Bleed the hydraulic unit and brake circuits.
Use this command if abnormally long brake pedal travel is noted during a road test with ABS control
(the system must have been bled beforehand by the usual procedure).
Select the SC006 "Bleed hydraulic unit and brake circuit" command and follow the instructions
given by the diagnostic tool.

NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Disconnect one wheel speed sensor. Start the
engine and check that only the ABS fault warning
light comes on. Do not drive the vehicle if the brake
fault warning light is also lit, as the brake limiter
function is no longer guaranteed to operate
correctly. Carry out a road test with the ABS
deactivated.
Is the fault still present under these conditions?
no
Raise the vehicle so that you can rotate the wheels
and check:
–Possible inversion when connecting the speed
sensors.
–Possible inversion of pipes on the hydraulic unit.
To carry out these two tests, refer to and follow the
procedures given in ALP 2.
Check the condition of the ABS targets and that they
conform to specifications.
Also check the sensor/target air gap over one
revolution of each front and rear wheel.
If the fault is still present, contact the Techline.
yesIf the brake pedal travel is relatively long,
bleed the brake circuit.
If the travel is normal, check the tyre
pressures, the front axle, or for any leaks
in the circuit.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

*ASR: Traction control
ALP15ESP warning light comes on with the "ASR* disconnected or off"
message when the current is switched on without pressing the
ESP disconnection button
NOTESConsult this customer complaint only if the "Service", "ABS" and "Brake" warning lights
are not lit.
After disconnecting the battery, it is probable that the electric power steering loses the steering wheel angle
sensor indexing (the electric power steering no longer sends the steering wheel angle signal to the ESP, which is
then disabled).
The ESP system is not faulty, no fault is present in the fault memory, the ESP warning light comes on and the
"ASR disconnected or off" message indicate this transient and reversible status.
To restore the electric power steering indexing and enable the ESP again, it is necessary to:
–switch on the ignition or start the engine (to obtain maximum steering assistance),
–turn the steering wheel slowly to full right lock, to full left lock, then return slowly to the centre point after going
slightly past it,
–the ESP warning light should go out and the message "ASR disconnected or off" should disappear,
–stop the engine and switch off the ignition,
–switch on the ignition, start the engine and see that the warning light no longer lights up.
If the warning light and the message reappear, start the procedure described above again.
If the operation fails again or if this customer complaint appears without the battery having been disconnected, run
fault finding on the electric power steering and repair accordingly.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
