AFTER REPAIRStart the status and parameter check again from the beginning.
DIAG 10
Fiche n° 27
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.

Use the 30 track adaptor of the XRBAG to operate on the computer connector .
Erase the computer memory using the command G0**. AFTER REPAIR NOTES
Carry out the operations necessary to obtain the correct computer power supply :
10.5 volts ± 0.1 < correct voltage< 16 volts ± 0.1.
- Check the battery charge.
- Check the charge circuit.
- Check the tightness and condition of the battery terminals.
- Check the computer earth .
NoneNOTES I.dEF - 2.dEF
For a micro-break fault, check the computer power supply lines :
- Condition of the computer connections.
- Condition of computer earth (track 9 of the 30 track connector towards front right pillar earth).
- Condition / position of the fuse.
- Condition and tightening of battery terminals.
NoneNOTES 3.dEF
The dEF display on the kit indicates the minimum memorisation of 2 of the 3 faults declared by the
display
1.dEF, 2.dEF and 3.dEF (bargraph flashing ).
Operation:
- Check the battery charge.
- Check the charge circuit.
- Check the tightness and condition of the battery terminals.
- Condition of the computer connections.
- Check the computer earth .
- Condition / position of the fuse.
