Check the connection and the condition of the connections of the front right-hand wheel speed sensor, component
code 152. 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.
Disconnect the sensor, use command AC013 Wheel speed sensor supply test and check that pulses of voltage
of approximately 12 V are detected by a multimeter at the sensor connector terminals on the computer side.
Are the pulses present?

otherwise replace the wiring.
Check and ensure the continuity of the following connections:
–4M between components 152 and 118,
–4N between components 152 and 118.
Also check the insulation between these two connections.
If the connection or connections are faulty and if there is a repair procedure (see

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 that the wheel speed sensor mounting is in good condition (correct clipping).
Check the conformity of the target (condition, number of teeth = 48 or 44 depending on the version) with the specific
command SC001 Check target teeth.
If the checks are correct:
– clear the computer fault memory using the command RZ001 Fault memory,
– exit fault finding mode, switch off the ignition and carry out a road test.
Replace the instrumented bearing if the fault recurs.
If the fault is still present, contact the Techline.
