LEFT-HAND FRONT WHEEL TARGET
NOTESSpecial notes:
This fault means that some magnetic poles of the target are not detected by the sensor.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test at a speed of > 36 mph (60 km/h).
Check for play in the bearing.
Visually inspect the condition of the target and sensor (for dirt, metallic contamination, bearing grease, etc.), and
clean using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the sensor/target air gap over one wheel revolution: 0.1 mm < front wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
Replace the instrumented bearing if the number of teeth is incorrect.
If all the checks are correct, reconnect the computer and the wheel speed sensor.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a road test.
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.

NOTESSpecial notes:
Carry out the checks only if the "pressed" and "released" statuses are not
consistent with the pedal position.
STATUS IS "RELEASED" WITH BRAKE PEDAL PRESSED.
If brake lights operate:
–Check the continuity of the connection between track 1 of the brake light switch connector and track 20 of the
computer connector.
If the brake lights do not operate:
–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.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP1 No dialogue with the ABS computer
NOTESSpecial notes:
To run fault finding on the vehicle's computers, switch on the ignition in fault
finding mode (forced + after ignition feed). Proceed as follows:
–with the vehicle card in the card reader, press the Start button for more than
5 seconds outside of starting conditions.
Check that the CLIP diagnostic tool is equipped with the latest update available.
Check that the diagnostic tool is not causing the fault by trying to establish dialogue with a computer on another
vehicle. 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 necessary work 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, tightness of the earth screw above the ABS
assembly). Check that the supply to the computer is correct:
–Earth on tracks 1 and 4 of the 26-track connector.
–+ before ignition feed on tracks 2 and 3 of the 26-track connector.
–+ after ignition feed on track 18 of the 26-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 memory.
Carry out a road test followed by another check with the diagnostic tool.

–return to the home menu of the CLIP screen,
–switch off the ignition,
–switch on the ignition again,
–test the computers against without making the automatic VIN code acquisition.
If the fault is still present, follow ALP 1.
