If BG 6RH is also illuminated, check line 45 of the computer.
If BG 6LH or BG 4LH is also illuminated, check line 44 of the computer.NOTES
Check that the pressure sensor is connected correctly both electrically and pneumatically.
Check the conformity of the pressure sensor pipe (it must not be pierced or blocked...).
The fault persists! Replace the injection computer.
IMPORTANT: The computer has probably been damaged by an electric shock. The cause of the damage
must be found before fitting a new computer.
The fault persists! Replace the sensor.

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.
NOTES
Fiche n° 53 8
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).

hing on the left or right hand side.
To confirm their presence and therefore the need to apply the fault finding be-

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.

If bargraph 10 RH is flashing, confirm the presence of the fault and therefore the
need to apply fault finding below, using command G20* on the XR25 kit.
The fault is present if the bargraph re-illuminates at the end of the command.

Use of command modes:
Solenoid valve control for hydraulic inspection: G03* to G06*
Lift vehicle so that the wheels can be turned and check that they turn freely.
Keep the brake pedal pressed down so that the wheel being tested cannot be turned by hand (do
not press the brake too hard to ensure you are at the releasing limit).
Enter G0X* Ten cycles of unlocking/locking must be noted for the wheel concerned.
Pump motor control : G08*
Enter G08* and apply brake Pump operation must be noted for 2 se-
conds.
Pump motor and solenoid valve control : G20*
Enter G20* and apply brake Brief motor and solenoid valve opera-
tion must be noted.
Bleeding of hydraulic circuits : G15*3* front left / G15*4* front right / G15*5* rear left / G15*6* rear
right
Apply the procedure described in the section "Bleeding the circuits" in the Workshop Repair Manual.
