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
The fault persists! Replace the sensor.

This vehicle is not fitted with ADAC at the moment.
If another bargraph is illuminated, refer to the fault finding for that bargraph.NOTES
If your vehicle has ADAC,
this method of fault finding will not be of use for this fault.
This bargraph is often illuminated or flashing in the following cases:
-Air conditioning compressor command mode G12*.
-Fault on fuel pump relay circuit.
-Other cases, which have not yet been noted, may well exist.

Connect the bornier in place of the computer and check the insulation and continuity of line 51 on the
computer.
Repair if necessary.
Check that the vehicle has air conditioning and if it is not fitted with air
conditioning, deal with the other bargraphs first.
Engine running, select the air conditioning function.
NOTES
If the fault persists, refer to the air conditioning fault finding.

RICHNESS REGULATION
XR25 aid:Richness regulation faulty
No fault bargraphs should be illuminated.
Ignition correct (a check may be made using the OPTIMA 5800 station).
No other status bargraph should show a fault.
NOTES
Check the sealing of the canister bleed valve (a leak can disrupt the richness considerably).
Check the sealing of the exhaust pipe upstream from the oxygen sensor.
Check the sealing of the inlet manifold.
If the vehicle has only been driven in town, the sensor is contaminated (try driving under load).
Check the fuel pressure.
If the idle speed is unstable, check the valve clearances.
Check the injectors (flow and shape of the jet).
If necessary, replace the oxygen sensor.
Check the connection and condition of the oxygen sensor connector.
Ignition on, during the timed phase, check 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.
