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).

Even if present at time of test, these faults will always be declared by BG9 flas-
hing 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.

first.

first.
NOTES
Fiche n° 53 9
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.

LOCKING OF ONE OR MORE WHEELSFault chart 4
REMINDER:Wheel locking on a vehicle equipped with ABS, or tyre squeal, considered by the customer
as locking, can be linked to a normal reaction of the system and should not be systematically
considered as a fault :
- locking is allowed below 3.75 mph ( 6 km/h) (the system will not provide regulation).
- Braking with ABS regulation under very bad road conditions (high degree of tyre squeal).
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Only consult this section after a complete check with the XR25 kit.NOTES
On the other hand, if there really is wheel locking on one or more wheels, lift the vehicle so the wheels can
be turned, and check :
- a possible incorrect connection in the speed sensor connection.
• Use operations #01, #02, #03 and #04 while turning the appropriate wheel and ensure the consis-
tency of the results obtained .
• If the value measured is zero, turn the other wheels to confirm a bad electrical connection of the sen-
sors and repair the wiring.
- A possible incorrect connection of the hydraulic assembly pipes.
• Use operations G03*, G04*, G05* and G06* while applying the brake and check for the ten cycles of
unlocking/locking on the wheel concerned (consult section "Aid").
• If the ten cycles do not occur on the wheel tested, (wheel remains locked), see if they occur on ano-
ther wheel (if a bad connection is confirmed: repair).
• If the ten cycles do not occur on a wheel and the pipes are correctly connected, replace the hydraulic
assembly.
• Check the condition of the ABS targets and that they conform.
• Also check the sensor/target air gap by rotating each of the wheels :
Front 0.13 mm < air gap over one rotation < 1.96 mm.
Rear 0.03 mm < air gap over one rotation < 2.4 mm (check only possible on vehicles with four-bar
rear axles).
If the fault persists after these checks, replace the hydraulic assembly.
