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.
Bargraph 3 RH flashing
Engine speed sensor circuit3
The engine speed sensor circuit fault is present if the bargraph illuminates when
the engine is running.
Use bornier Elé. 1332 for any operations on the computer connector.
NOTES
Measure the resistance of the flywheel signal sensor at its connector. Replace the sensor if the resistance
is not approximately 250 ohms.
Ensure the continuity and insulation of the following lines:
- Between track 8 on the computer connector and track B on the flywheel signal sensor connector.
- Between track 3 on the computer connector and track A on the flywheel signal sensor connector.
Also check the insulation between these two connections.
Test the connections on the 2 connectors.
Carry out a visual inspection of the general condition of the wiring and its routing for possible
interference.
Fiche n° 60 1/2
Check the positioning and condition of the sensor.
Check the condition of the target (deformation, mounting, noise....).
Check the conformity of the target: 2 gaps at 180°.
If the fault persists after these tests, replace the flywheel signal sensor.
If the "engine speed sensor circuit" fault reappears, replace the computer (consult the "Aid" section for
this operation).
13-11

Connect the bornier in place of the computer and check the insulation,
continuity and that there is no interference resistance on the line:

Computer 34 A Target sensor

If BG 5RH is flashing, erase the computer memory using G0**.
Try to start the vehicle.
If BG 5RH becomes permanently illuminated or flashes, deal with this fault.
NOTES
*25 = CO.0
*25 = CC.0Check the condition of the flywheel, especially if it has been removed.
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.
Check the target sensor has been correctly connected (the sensor connector must
not be inverted).
Repair if necessary.*25 = In
