If brake lights are operating
:
- Ensure continuity between dashboard / rear left R2 connector on track 7 and track 14 of the ABS
computer connector .
Dashboard / ABS R36 intermediate connector (track 8).
If brake lights are not operating
:
- Check condition and adjustment of brake light switch as well as the 15A fuse for the brake lights (in
the passenger compartment connection unit). Replace if necessary.
- Disconnect the brake light switch, then check / ensure presence of + after ignition feed on track A3
of the connector
- Check operation of brake light switch (closed contact between tracks A3 and B1).
- Check and ensure continuity between track B1 of the brake light switch connector and the dashboard
/ rear left hand side R2 connector on track 7.
Bargraph 13 permanently illuminated on left hand side
- Check the condition and adjustment of the brake light switch. Replace if necessary.
- Check the operation of the brake light switch contact (closed contact between tracks A3 and B1).
Replace the brake light switch if there is permanent continuity between the two tracks.
- Check and ensure insulation from 12 volts of the connection between track B1 of the brake light
switch connector and track 14 of the ABS computer connector .
Intermediate connectors : Dashboard / ABS R36 on track 8.

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

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.

PULLINGFault chart 5
Only consult this section after a complete check with the XR25 kit.NOTES
Lift the vehicle so the wheels can be turned
and check for :
- a possible incorrect connection in the
speed sensors,
- a possible incorrect connection of the
hydraulic assembly piping.
For these two checks, consult and apply the
methods defined in Fault Chart 4.Check the
condition of the ABS targets and that they
conform. Also check the sensor/ target air
gap by rotating each wheel.
If the fault persists, replace the hydraulic
assembly.
If the pedal travel is relatively long, bleed
the brake circuit.
If it is normal, check the tyre pressure, the
front axle assembly
or possibly for leaks in the circuit.
no
Remove the 10A ABS fuse on the passenger
compartment connection unit and carry out
a road test with the ABS non-operational.
Does the fault persist under these
conditions?
