Check the resistance of the canister bleed valve.
Replace the valve if necessary.
Check, ignition on , for 12 V on track A of the canister bleed valve.
Repair 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.

DIAG 1BATTERY VOLTAGEFiche n° 27
XR25 aid: Battery voltage ignition on, Minimum< # 04 < Maximum
Battery voltage idle speed, Minimum< # 04 < Maximum
No fault bargraphs should be illuminated.
No consumersNOTES
If # 04 < Minimum, the battery is discharged:
Check the charging circuit to determine the cause of this fault.
Ignition on
If # 04 > Maximum, the battery may be overcharged:
Check the charging voltage is correct with and without consumers.
If # 04 < Minimum, the charging voltage is too low:
Check the charging circuit to determine the cause of this fault.
At idle speed
If # 04 > Maximum, the charging voltage is too high:
The alternator regulator is faulty. Repair this fault and check the electrolyte level in the battery.
NOTE:
The battery and the charging circuit may be checked using the OPTIMA 5800 station (measurement does
not require the battery to be disconnected, which retains the memories of the computers).

Check the resistance of the throttle potentiometer.
Replace the throttle potentiometer if necessary.

Check the resistance of the throttle potentiometer when the throttle is activated.
If the resistance varies, check the electrical lines of the sensor.
If the resistance does not vary, check that the sensor is connected mechanically to the throttle.
If necessary, replace the sensor.

Check the upper and lower stops of the throttle.
Check the accelerator control (points of resistance and friction).
