NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Using the diagnostic tool, check that ET017 is functioning correctly.
If not, apply the fault finding procedure described above for ET017.
If the lights still do not work, check the functioning of the light-switch relay.
The relay is passed at rest (check the continuity between tracks 3 and 4 of the relay). Replace the relay if
necessary.
Check the continuity of the connection between track 1 of the brake light switch and track 4 of the relay mounting.
Repair if necessary.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP14 Erratic ESP regulation
NOTESOnly consult this customer complaint after a complete check with the diagnostic
tool.
Check that the four tyres on the vehicle are identical.
Using the diagnostic tool, you must ensure that the value of configuration PR063 "Vehicle parameters"
matches the definition of the vehicle undergoing diagnostics.
If necessary, run command VP004 Vehicle parameters using the diagnostic tool to define the appropriate
parameters for the vehicle type.
Check the connection and condition of the combined sensor connector.
Check that the orientation of the combined sensor on the body is correct and that it is correctly mounted.
Calibrate the steering wheel angle in the Electric power-assisted steering domain using the diagnostic tool.
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".
Carry out a road test followed by another check with the diagnostic tool.
If the fault is still present, adjust the axle assembly geometries. Adjust if necessary and calibrate the steering
wheel angle again in the Electric power assisted steering domain using the diagnostic tool.
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".
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.

*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.
