Fault finding - Interpretation of XR25 bargraphs13
AFTER REPAIRErase the computer memory (G0**), switch the ignition off, then carry out a road
test.
Finish the operation by checking using the XR25.

co.0
Measure the resistance of the EGR solenoid valve at its connector. Replace the EGR solenoid valve if the
resistance is not approximately 45 ohms.
Ensure continuity of the connection between track 5 on the computer connector and track 1 of the EGR
solenoid valve connector.
Ensure the presence of + after ignition feed on track 2 of the EGR solenoid valve connector, wiring side.
Ensure the insulation from earth of the connection between track 5 on the computer connector and track 1
of the EGR solenoid valve connector.
Test the connections on the 2 connectors.
None NOTES
If the fault persists after these tests, replace the EGR solenoid valve.
If the "EGR solenoid valve circuit" fault reappears, replace the computer (consult the "Aid" section for this
operation).
cc.1
Measure the resistance of the EGR solenoid valve at its connector. Replace the EGR solenoid valve if the
resistance is not approximately 45 ohms.
Ensure insulation in relation to +12 volts of the connection between track 5 on the computer connector and
track 2 of the EGR solenoid valve connector.
Even if present at the moment of testing, this fault is still declared
by a flashing BG 7RH side. To confirm its presence and the necessity
of following the fault finding below, start the engine.
The fault is present if the bargraph illuminates when the engine is
running.
NOTES
If the fault persists after these tests, replace the EGR solenoid valve.
If the "EGR solenoid valve circuit" fault reappears, replace the computer (consult the "Aid" section for this
operation).

co.0
Measure the resistance of the PAS pump assembly relay coil (position C on the engine connection unit).
Replace the relay if its resistance is not approximately 65 ohms.
Ensure the continuity and insulation from earth of the connection between track 20 on the computer
connector and terminal 2 on the pump assembly relay mounting.
Ensure the presence of + after ignition feed at terminal 1 of the pump assembly relay mounting.
Check the connections on the computer connector and the relay mounting.
None NOTES
If the fault persists after these tests, replace the PAS pump assembly relay.
If the "PAS pump assembly relay control circuit" fault reappears, replace the injection computer (consult
the "Aid" section for this operation).
cc.1
Measure the resistance of the PAS pump assembly relay coil (position C on the engine connection unit).
Replace the relay if its resistance is not approximately 65 ohms.
Ensure the insulation from + 12 Volts of the connection between track 20 of the computer connector
and terminal 2 on the pump assembly relay mounting.
Even if present at the moment of testing, this fault is still declared
by a flashing BG 9RH side. To confirm its presence and the necessity
of following the fault finding below, erase the computer memory
then start command mode G36*.
The fault is present if the bargraph flashes again.
NOTES
If the fault persists after these tests, replace the PAS pump assembly relay.
If the "PAS pump assembly relay control circuit" fault reappears, replace the injection computer (consult
the "Aid" section for this operation).

test.
Finish the operation by checking using the XR25.
Bargraph 12 RH illuminated
Full load or no load not programmed12
None NOTES
Programme the full load position of the accelerator pedal using command G31* (do not adjust the load
lever directly).
Enter code G31* on the XR25 (engine speed zero).
- Press the accelerator pedal when the display flashes "PF".
The display then shows "bon", "Fin" then "6/7.dIE" when the procedure has been completed correct-
ly. Bargraph 12 RH side must be extinguished.
- Switch off the ignition.

Fiche n° 60 1/2
cc.1
Ensure insulation in relation to 12 volts of the connection between track 19 on the computer connector
and track 18 on the air conditioning computer connector.
Test the connections on the 2 connectors (+ intermediate connection engine / dashboard).
Even if present at the moment of testing, this fault is still declared
by a flashing BG 13LH side. To confirm its presence and the necessity
of following the fault finding below, erase the computer memory
then start the engine. The fault is present if the bargraph flashes
when the engine is running.
NOTES
If the fault persists after these tests, replace the air conditioning control module.
If the "air conditioning cut out information "fault reappears, replace the diesel injection computer (consult
the "Aid" section for this operation).
