BATTERY WARNING LIGHT
NOTESCheck that the status is OUT with the engine running and LIT with the engine stopped
and the ignition on.
Check consistency with the instrument panel warning light.
With the engine running, check that the battery voltage is much higher than +12 V.
Perform a fault finding procedure on the charge circuit if necessary.
Check the status and the connection of connector PEM on the UPC and of the connections on the alternator.
Repair if necessary.
Turn off the ignition and ensure that there is insulation against +12 V and continuity in the connection:
UPC connector PEM track 8 Track 1 of the alternator 2-track connector
Repair if necessary.
With the ignition on, ensure that there is insulation against earth and the continuity in the connection:
UPC connector PEM track 8 Track 1 of the alternator 2-track connector
Repair if necessary.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

WINDSCREEN WIPER PROTECTION
NOTESBefore starting, check the operation of the windscreen wiper motor by running
commands AC005 Windscreen wiper at low speed and AC006 Windscreen wiper
at high speedand then check the park position using command AC012 Windscreen
wiper park position.
These statuses are listed in the order of severity or persistance of incorrect wiper
operation.
–if the status is INACTIVE, the wiper function is normal.
–If the status is LOW SPEED, the UPC has detected an abnormal wiper operation on
the higher speed setting for more than 6 seconds (the wiper has stuck or is blocked);
windscreen wiping is therefore forced to operate on the lower speed setting when
the higher speed setting is requested,
–If the status is INTERMITTENT, the wiper function is stopped for 10 seconds
following the detection and persistence of the fault (restrained or blocked),
–If the status is BLOCKED, wiping stops 30 seconds after the malfunction has lasted
for more than 2 minutes.
The status returns to INACTIVE, once the UCH requests a new wiping instruction (by
following the movement of the wiper stalk or by request from the rain sensor).
Make sure that nothing is mechanically blocking movement of the wiper blades (blades stuck, condition and
assembly of the wiper mechanism linkage and no object interfering with the motion of the device).
Check that the wiper mechanism is not seized.
Repair if necessary.
Check the status and the connection of connectors PPH2 and PEH on the UPC and of the windscreen wiper
motor.
Repair if necessary.

REVERSE GEAR ENGAGED
NOTESCheck, and if necessary, replace fuse 5C on the UPC.
Check the status and the connection of the reverse gear switch connector and connector PPM2 on the UPC.
Repair if necessary.
With the ignition on and reverse gear selected, check the presence of +12 V on track 9 of connector PPM2.
If there is a fault, check the insulation against earth and continuity of the connections:
UPC connector PPM2 track 9 Track 1 (track 3 on the ND0 gearbox) of the switch
UPC connector PPM2 track 6 Track 2 (track 1 on gearbox ND0) of the switch
Repair if necessary.
With reverse gear selected, check the continuity between tracks 1 and 2 (or tracks 1 and 3 on gearbox NDO)
of the switch.
Replace the reverse gear switch if necessary.
If the fault is still present, contact the Techline.
