Note:
The left and right-hand xenon bulb computers are supplied when the dipped headlights are lit. Therefore fault
finding can only be carried out on them after the ignition has been switched on in fault finding mode (forced + after
ignition feed) and the dipped headlights have been switched on.

STORED
FRONT RIGHT-HAND 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.

Measure the voltage across tracks 3 and 6 of the combined sensor connector with + after ignition feed
switched on.
If the voltage is not approximately the same as + after ignition feed, contact the Techline.
Check the connection and condition of the combined sensor and computer connectors.
Visually inspect the sensor wiring.
Check and ensure continuity and the insulation of the connections between:
Sensor connector track 1 Track 18 computer connector
Sensor connector track 2 Track 37 computer connector
Sensor connector track 3Passenger compartment fuse box
Sensor connector track 4 Track 16 computer connector
Sensor connector track 5 Track 20 computer connector
Sensor connector track 6 Track 15 computer connector
Also check the insulation between these connections.
If the results of the checks are correct, reconnect the computer and the combined sensor.
Clear the computer fault memory. Exit fault finding mode and switch off the ignition.
Switch the ignition on and replace the sensor if the fault recurs.

Diagnostic - Fault finding chart
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.
