Wheel speed sensor:
Gives the speed of each of the vehicle's wheels.
Analysis of the speeds of the right-hand and left-hand wheel allows the turning direction of the vehicle to be
deduced.
Brake lights switch:
Visual indication of the brake pedal position.
It indicates whether the driver is depressing the brake pedal.

On this vehicle, the main functions of the ABS are as follows:
● electronic distribution of braking between front and rear by controlling skidding of the rear wheels,
● keeping the wheels from locking by controlling skidding of the four wheels.
The ABS prevents the wheels from locking when braking. This function allows the vehicle to be steered under
braking and ensures vehicle stability under braking.
EBD (electronic braking distribution):
The electronic braking distribution unit optimises the brakeforce distribution between the front and rear axles. This
function ensures vehicle stability under braking.

Check the connection and condition of the connections of the front left-hand wheel speed sensor, component code
153.
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?

If pulses are detected, the front left-hand wheel speed sensor is defective, replace
the sensor.
NOCheck the connection and condition of the connections of the ABS computer,

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.
Check and ensure the continuity of the following connections:
–4E between components 153 and 118,
–4C between components 153 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
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

Check the connection and condition of the connections of the front left-hand wheel speed sensor, component code
153.
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.
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.
