REPRESENTATION OF THE BARGRAPHS
Illuminates when a dialogue has been established with the product computer. If it remains
extinguished:
- the code does not exist,
- there is a fault in the tool, the computer or the line
REPRESENTATION OF THE FAULTS (always on a coloured background)
If illuminated, indicates a fault on the tested product, the associated text defines the fault.
If extinguished, indicates that the fault has not been found on the tested product.
REPRESENTATION OF THE STATUSES (always on a white background)
Engine off, ignition on, no operator action
The status bargraphs on the fiche are represented as the status which they should have when the engine is
off, the ignition is on and there is no operator action
- If on the fiche the bargraph is represented as
- If on the fiche the bargraph is represented as

Extinguishes when the function or condition given on the fiche is no longer performed.
Illuminates when the function or condition given on the fiche is performed
Fiche n° 27 is a generic fiche used for several engines.
The different engines do not use all the bargraphs. To find out the bargraphs dealt with by the injection
computer, after having set up a dialogue with the computer, press the V and 9 buttons simultaneously.
The bargraphs dealt with will:
- illuminate permanently for non memorisable fault bargraphs or status bargraphs,
- flash for memorisable fault bargraphs.
To return to fault finding mode, press button D.

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.

Ignore this bargraph if the vehicle is not fitted with an immobiliser.NOTES
Connect the bornier in place of the computer and check the insulation, continuity and that there is no
interference resistance on the wiring on track 37 of the computer.
Repair if necessary.
If the fault persists, refer to the immobiliser fault finding.

Check the resistance of the sensor. Replace it if necessary.
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.

If BG 3RH is flashing, increase the engine speed to 2500 rpm for 5 minutes
If BG3RH becomes permanently illuminated, deal with the fault.
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.
The fault persists. Replace the oxygen sensor.
The fault persists! Replace the injection computer.
