*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.

NOTESOnly consult this customer complaint after a complete check with the diagnostic
tool.
Check the condition and connection of the
battery terminals.
Is the battery in good condition?
YES
Check the 50A power fuse in position 5 on
the power fuse board. Check fuse F13 (25A)
on the UPC and the correct locking of the
grey 4-track PPH1 connector (Vdiag 44) or
the 25A fuse F8 on the UPC and the correct
locking of the black 6-track CM connector
(Vdiag 48 or higher).
Are the fuses and connectors correct?
YES
Check the connection and condition of the tab
1 red wire of the grey connector.
Is the connector correct?
YES
NOClean the battery terminals.
NOIf the connector is faulty and there is a repair
procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions
for repair), repair the connector, otherwise
replace the wiring.
Replace any faulty fuses. Switch on the ignition
again.
Is the replaced fuse or fuses correct?
NO
Check the insulation to earth between:
–fuse 50A and track 2 of the computer
–fuse 25A and track 3 of the computer
Are the connections correct?
NO YES
Contact the Techline.
If the connection(s) are faulty and there is a repair method
(see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
NO
If the connector is faulty and there is a repair method (see Technical
Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the connector, otherwise replace the wiring.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
