0B, 12 and 11) using command RZ003 "ESP sensor programming".
2.DEF
NOTESNone
Check that the combined sensor is correctly fitted and attached to the vehicle chassis. The combined sensor is
marked with an arrow. You must make sure that this arrow is pointing to the front of the vehicle.
Clear the computer's fault memory and clear the ESP sensor programming (Vdiag 09, 0A, 0B, 12 and 11) with
command RZ003 “ESP sensor programming”.
Switch off the ignition and carry out a road test.
AFTER REPAIRClear the computer fault memory. If the combined sensor has been replaced, erase the
ESP sensor programming (Vdiag 09, 0A, 0B and 11) with command RZ003 ESP

NOTESSpecial notes:
Although it is stored in the computer, the ABS/ESP system is not faulty. The ESP is
deactivated due to unusable information from the electric power steering system. Run
fault finding on the electric power steering with the diagnostic tool.
Note:
The electric power steering does not always store these transient faults as quickly as
the ABS/ESP system.
If no fault is stored in the electric power steering computer memory, start the engine; if
no present fault is displayed, contact the Techline. Once the fault in the electric power
steering system 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.
1.DEF
NOTESNone
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of
the tyres.
Check the axle assemblies, adjust if necessary.
Calibrate the steering wheel angle in the electric power-assisted steering using the diagnostic tool.
Ensure that the combined sensor is properly fixed to the body in the right direction (arrow towards the front of
the vehicle).
If all the checks are OK, clear the computer fault memory and clear the ESP sensor programming (Vdiag 09, 0A,
0B, 12 and 11) using command RZ003 "ESP sensor programming".
Carry out a road test.
AFTER REPAIRClear the computer fault memory.

ALP 2 Locking of one or more wheels
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Reminder: wheel lock on a vehicle equipped with ABS, or tyre squealing perceived by the customer as locking,
may be part of the normal operation of the system and should not be automatically considered as faults:
–Braking with ABS on very poor roads (significant squealing).
However, if the wheels are actually locking, raise the vehicle in order to be able to turn the wheels and check:
–Possible inversion when connecting the speed sensors.
Using parameters PR001, PR002, PR003 and PR004, rotate the wheels slowly and check the consistency of the
results obtained.
If the value measured is zero, rotate the other wheels to confirm an electrical inversion of the sensors and repair
the wiring harness.
–Possible inversion of pipes on the hydraulic unit.
Use commands AC003 Front left-hand wheel solenoid valves, AC004 Front right-hand wheel solenoid
valves, AC005 Rear left-hand wheel solenoid valves and AC006 Rear right-hand wheel solenoid valves
while depressing the brake pedal and check for the occurrence of 5 locking/unlocking cycles on the wheel
concerned (see Dealing with commands). If the 5 cycles do not occur on the wheel tested (wheel remains
locked), check whether they occur on another wheel to confirm transposed pipes.
If the 5 cycles are not detected on a wheel and the pipes have not been subject to inversion, replace the hydraulic
unit.
Check that the sensor casing is secured when rotating.
Check the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the conformity of the targets using special command SC001 "Check target teeth": condition, number of
teeth = 48.
If the fault is still present after these checks, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with 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.

ALP 5Unexpected ABS operation at low speed and with slight
pedal pressure
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Important: ABS regulation may be unresponsive when the vehicle is driven on surfaces
such as icy roads, cobbled streets, etc.
It is possible to feel brake pedal vibrations which are associated with the reaction of the system in particular
circumstances, such as:
–crossing rumble strips,
–tight cornering with lifting of the inside rear wheel.
These vibrations may be linked to simple brake limiter activation, when the pressure on the rear axle is limited.
If the fault is different, check the speed sensor connectors (micro-breaks) as well as the air gaps.
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.
