XR25)Fault chart 2
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

Fiche n° 56
Check the continuity and insulation from earth and from 12 volts of the wiring between track A6 of the
18 track decoder unit connector and track ** of the injection computer .
Repair the wiring if necessary.
Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").
Ignition on, check for pulses on track A6 of the decoder unit connector (test with decoder unit and
solenoid valve coded electronic unit connectors connected).
Are there any pulses ?
Replace the injection computer.YES
NOReplace the decoder unit.
** track : 43 or 19 depending on engine
Erase the memorised fault by entering GO** on the XR25 keyboard.
Carry out a conformity check.
Check operation of the immobiliser system.
For petrol vehicles, if bargraph 6 right hand side is illuminated, check the impact switch.
