BRAKE PEDAL
NOTESSpecial notes:
Carry out the checks only if the pressed and released statuses are not consistent with
the pedal position.
STATUS Released Brake pedal depressed.
If the brake lights are working:
–Check the continuity of the connection between track 1 of the brake light switch connector and track 30 of the
computer connector.
If the brake lights are not working:
–Check the brake light lighting relay,
–Check the condition and fitting of the brake light switch and brake lights fuse.
–Remove the brake light switch and check that it is operating correctly:
Continuity between tracks Insulation between tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(Brake pedal depressed)1 and 2 3 and 4
–Replace the switch if necessary.
–Check for + after ignition feed on tracks 2 and 4 on the brake light switch connector.
If the brake lights still fail, check/ensure the continuity between track 1 of the switch connector and track 4 of the
relay mounting.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 1 No dialogue with the ABS computer
NOTESSpecial note:
To run fault finding on the vehicle's computers, switch on the ignition in fault finding
mode (forced + after ignition feed), i.e. proceed as follows:
–With the vehicle card in the card reader, press the Start button for more than
5 seconds without starting conditions being met.
Check that the CLIP diagnostic tool is equipped with the latest update available.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty.
If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the
cause could be a faulty computer interfering on the multiplex network. Check the battery voltage and carry out the
operations necessary to obtain the correct voltage (9.5 V < battery voltage < 17.5 V).
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
Check the presence and the condition of the ABS fuses on the passenger compartment fuse board and in the
engine fuse box.
Check that the computer connector is properly connected and check the condition of its connections.
Check the ABS earths (good condition, not corroded, earth screw on top of the ABS unit tight).
Check that the supply to the computer is correct:
–Earth on tracks 1 and 4 of the 46-track connector.
–+ before ignition feed on tracks 2 and 3 of the 46-track connector.
–+ after ignition feed on track 18 of the 46-track connector.
Check that the power supply to the diagnostic socket is correct:
–+ before ignition feed on track 16.
–+ after ignition feed on track 1.
–Earth on tracks 4 and 5.
If dialogue has still not been established 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.

ALP 7Unexpected ABS operation when using special equipment
(car phone, CB, etc.)
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the equipment which is causing the fault is approved.
Check that this equipment has been correctly installed without modification to the original wiring, in particular, that
of the ABS system (connections to earth and + after ignition/before ignition of the ABS are not permitted).
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 12ABS computer not detected during the multiplex network test
on CLIP
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the CLIP diagnostic tool is equipped with the latest update available.
If the ABS computer is not detected after the multiplex network test on the CLIP, carry out the following operations:
–return to the home menu of the CLIP screen,
–switch off the ignition,
–switch on the ignition again,
–test the computers again without the automatic acquisition of the VIN code.
If the fault is still present, follow ALP 1.
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.
