This bargraph must be illuminated for fault findingNOTES
Test the XR25 on another vehicle.
Check:
- the injection, engine and passenger compartment fuses,
- the connection between the XR25 and the diagnostic socket,
- the position of the ISO selector (S8),
- the conformity of the cassette.
Repair if necessary.
Check:
- the presence of + 12 V on track 16 and earth on track 5 of the diagnostic socket,
- that the XR25 cable is in good condition.
Repair if necessary.
Check, ignition on, for 12 V on track:
- 1 on the main relay,
- 3 on the main relay,
- 1 on the fuel pump relay.
Repair if necessary.
Ignition on, check for 12 V on track 5 of the main relay:
- If there is 12 V on track 5 of the main relay: replace the fuel pump relay.
- If there is not 12 V on track 5 of the main relay: replace the main relay.

NOTES
Check the connection and the condition of the connector on the oxygen sensor.
Check, ignition on during the timed phase, for :
- earth on track B of the oxygen sensor,
- + 12 V after the fuel pump relay on track A of the oxygen sensor.
Repair if necessary.
Check for the presence of earth on track 18 of the injection computer.
Repair if necessary.
The fault persists. Replace the oxygen sensor.
The fault persists! Replace the injection computer.
IMPORTANT: The computer has probably been damaged by an electric shock. The cause of the damage
must be found before fitting a new computer.
