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.

POSITION OF GEAR LEVER IN MANUAL GEARBOX
NOTESCheck, and if necessary, replace fuse "5C" on the UPC.
Applicable on vehicles fitted with a manual gearbox only.
Check the status and the connection of the neutral switch connector and connectors PPM2 and PEM on the
UPC.
Repair if necessary.
With the ignition on and in neutral, check the presence of +12 V on track 6 of connector PEM. If there is a fault,
check the insulation against earth and the continuity of the connection between the switch and track 6 of
connector PEM on the UPC.
Check the operation of the switch:
There is continuity between tracks 1 and 2 of the switch when the gearbox is in neutral.
There is an open circuit between tracks 1 and 2 of the switch when a gear is selected.
If faulty, replace the switch.
With the ignition on, check the presence of +12 V on track 2 (track 1 on gearbox ND0) of the neutral switch
connector.
If there is a fault, check the insulation against earth and the continuity of the connection between the switch
and track 6 of connector PPM2 on the UPC.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
