Bargraph 8 right or left hand side flashing
Front right or front left wheel sensor signal

Even if they are present at time of testing, these faults will always be declared by
BG 8 flashing on the left or right hand side.
To confirm their presence and therefore the need to apply the fault finding be-
low, carry out a road test. The fault is present if the bargraph illuminates during
the test.
If bargraphs 6 and 8 left hand side are both illuminated, deal with bargraph 6
first.
If bargraphs 6 and 8 right hand side are both illuminated, deal with bargraph 6
first.

Check the quality of the wheel speed sensor mounting (its position and that it is tightened to
recommended torque).Check the sensor / target air gap over one wheel revolution : 0.13 mm < air
gap< 1.96 mm. Check conformity of the target (condition, number of
teeth=26)
Carry out a visual inspection of the sensor wiring and check the quality of the connections on the 31 track
computer connector.
If all checks are correct, reconnect the computer and the wheel speed sensor, then erase the computer
memory.
Leave fault finding mode(G13*) and carry out a road test. Replace the sensor if the fault reappears.
If the fault reappears after replacing the sensor, it may be caused by an operating fault on a solenoid
valve and it is therefore necessary to carry out the hydraulic check of the solenoid valves with the XR25 kit
with command G03* or G04* (consult the section "Aid"). If the ten unlocking/locking cycles do not occur
on one of the wheels, replace the hydraulic assembly.
If the hydraulic assembly is not at fault, replace the computer.
Check the connection and condition of the sensor connections.
If the connector is correct , check the resistance of the sensor at its connector.
Replace the sensor if its resistance is not approximately 1.6 Kohms (1.6 Kohms ± 320 ohms).

Check the quality of the wheel speed sensor mounting (position and torque tightening).
Check the connection and condition of the sensor connections.
Check the connections at the intermediate connector under the body R101.
If the connector is correct , check the resistance of the sensor at its connector.
Replace the sensor if its resistance is not approximately 1.6 Kohms (1.6 Kohms ± 320 ohms).
Carry out a visual inspection of the sensor wiring and check the quality of the connections on the 31 track
computer connector.
If all checks are correct, reconnect the computer and the wheel speed sensor, then erase the computer
memory. Leave fault finding mode(G13*) and carry out a road test.
If the fault reappears, check the sensor/target air gap over one wheel rotation :
0.03 mm < air gap< 2.4 mm (test only possible on vehicle with 4 bar rear axle).
Check conformity of the target:condition, number of teeth = 26.
If the fault reappears after replacing sensor, it could be caused by a solenoid valve operating fault. It is
therefore necessary to carry out a hydraulic test of the solenoid valves with the XR25 kit with command
G05* or G06* (consult section"Aid"). If the ten unlocking/locking cycles do not occur on one of the
wheels, replace the hydraulic assembly.
If the hydraulic assembly is not at fault, replace the computer.
If all checks are correct, leave fault finding mode(G13*) and carry out a road test.
Replace the sensor if the fault reappears.
