Illuminated on right hand side if pedal not depressed.

BG 13 right remains permanently illuminated.
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.
Dashboard / rear left hand side R2 on track 7.

ABS WARNING LIGHT DOES NOT ILLUMINATE FOR 3
SECONDS WHEN IGNITION SWITCHED ONFault chart 1
Only consult this section after a complete check with the XR25 kit.NOTES
Check condition of ABS warning light bulb
and its power supply.
Ensure continuity of connection between
track 21 of the computer connector and the
warning light (track 3 of the black
instrument panel connector).
If fault persists, check the instrument panel
operation.
Carry out an inspection of the connections
on the 31 track connector.
Replace the computer if the fault persists.
no
Check the 15A instrument panel fuse on the
passenger compartment connection unit
(if the problem affects all instrument panel
operations).
Turn off the ignition.
Disconnect the computer, then switch on
the ignition again.
Does the warning light illuminate?

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?

LACK OF COMMUNICATION WITH
ABS COMPUTERFault chart 15
Only consult this section after a complete check with the XR25 kit.NOTES
If dialogue is still not established after these checks, replace the ABS computer.
Check that the diagnostic socket is receiving the correct power supply:
-+ before ignition on track 16,
-earth on track 5.
Check continuity and insulation of the lines of the diagnostic socket / ABS computer connections:
- between track 12 of the computer connector and track 15 of the diagnostic socket,
- between track 11 of the computer connector and track 7 of the diagnostic socket.
Check the presence and condition of the ABS fuse on the passenger compartment connection unit (10A).
Check the connection of the computer connector and the condition of its connections.
Check the connection and condition of the connections at the R36 dashboard / ABS connector.
Check the ABS earth leads (tighten the two earth bolts above the ABS assembly).
Check that the computer is receiving the proper power supply :
- earth on track 19 of the 31 track connector,
- +after ignition on track 15 of the 31 track connector.
Ensure that the XR25 is not at fault by trying to communicate with a computer on another vehicle. If the
XR25 is not at fault and dialogue is not being established with another computer on the same vehicle, it is
possible that a faulty computer is disturbing diagnostic lines K and L. Proceed with successive disconnec-
tions to localise this computer.
Check that the ISO interface is in position S8, that you are using the most recent version of the XR25 kit
and the correct access code.
Check the battery voltage and carry out the operations necessary to obtain the correct voltage (9.4 volts
< U battery< 17.4 volts).
