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.
1.dEF
This fault indicates that the advance corrector is seized, the injection pump has been incorrectly set or
there is a fuel supply fault.
It is taken into account when the advance noted by the needle lift sensor differs by more than 5° from the
advance value requested by the computer.
NOTE : If there is a fault where the advance corrector is seized, there will be a characteristic noise when
the ignition is switched on (irregular clicking of the corrector).
The fault is present if the bargraph is illuminated when the engine is
running.NOTES

CONT
- Check the condition of the fuel supply to the pump and the injectors (filter blocked, pipe kinked, air
leak, ...).
Check the type of diesel fuel used in extreme cold weather (a "summer " type diesel fuel may cause
this fault at -15 °C).
- Check the pump timing and check the tightness of the pump pulley.
- If the fuel supply and the pump timing are correct, replace the advance corrector.
