CONDITIONS FOR APPLICATION FOR THE TESTS DEFINED IN THIS FAULT FINDING
The tests described in this fault finding are only to be applied when the wording of the fault corresponds
exactly to the display on the XR25 kit.
If a fault is dealt with because there is a flashing bargraph, the conditions for confirming the existence of an
actual fault (and the need to apply the fault finding ) can be found in the "Notes" or at the beginning of the
bargraph interpretation.
If a bargraph is only interpreted when it is permanently illuminated, the application of the recommended
tests in the fault finding when the bargraph is flashing will not allow you to determine the origin of the
memorisation of this fault. In this case, only a test of the wiring and the connections of the component in
question must be carried out (the fault is simply memorised as it was not present at the time of testing).
NOTE : The ignition must have been switched off before the XR25 kit is used.
INDISPENSABLE TOOLING REQUIRED FOR OPERATIONS ON THE ABS SYSTEM
- XR25 kit.
- XR25 cassette n° 16 minimum.
Reminders :When there is intermittent fault memorisation, the ABS warning light will illuminate the next
time the vehicle is used until the car reaches 7.5mph (12 km/h). When the fault is memorised, a
counter relating to the fault is set at 40 . This value is reduced by one each time the ignition is
turned on if the fault is not present when the vehicle exceeds 7.5mph (12 km/h). When the
reading on the counter is equal to 1, it remains at 1 and the fault is not erased.

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?

Only consult this section after a complete check with the XR25 kit.NOTES
yes
Look for a short circuit to earth of the
connection between track 10 of the R36
connector and the ABS warning light (track
3 of the black instrument panel connector).Look for a fault in the shunt or a short
circuit to earth of the connection between
track 21 of the computer connector and R36
on track 10.
no
Disconnect the computer and check the
shunt positioning in the 31 track connector
(between track 19 and track 21).
Ensure on the computer side that a shunt
opening pin is present between tracks 19
and 21 of the computer connector.
Reconnect the computer.
Check that there is continuity between
track 10 of the R36 connector on the engine
compartment side, and earth.
Is continuity ensured ?

REILLUMINATION OF WARNING LIGHT AFTER STARTING THE ENGINE
TEMPORARY ILLUMINATION OF ABS WARNING LIGHT WHEN DRIVINGFault chart 3
Check the voltage of the computer power supply : 9.5 volts < correct voltage < 17.5 volts.
If necessary, carry out the following operations :
- Check the battery charge (check the charging circuit if necessary).
- Check the tightness and condition of the battery terminals.
- Check the ABS earths (tightness of two earth bolts above the ABS assembly).
Disconnect the computer and check the condition and the positioning of the shunt in the 31 track
connector (between track 19 and track 21).
Check on the computer side, the condition of the shunt opening pin.
Only consult this section after a complete check with the XR25 kit.NOTES

Using the XR25 kit, correctly reconfigure the decoder unit.
On the XR25 keyboard, enter G22*1* for a petrol vehicle
or G22*2* for a diesel vehicle
NOTE: In the diesel version, incorrect configuration of the decoder unit does not prevent proper
operation of the immobiliser. Nevertheless, if there is a fault, the immobiliser warning light will
not illuminate.
