Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

Fault finding - Function
DEACTIVATING THE SYSTEM
–The parking proximity sensor system can be deactivated in two ways:
–Temporary deactivation: briefly pressing (1 second) the parking distance control switch on the instrument panel
deactivates the system (the red warning light on the switch comes on). The function can be switched on again by
pressing briefly for a second time (the red indicator light on the switch goes out) or by switching the ignition off and
back on.
–Permanent deactivation: The parking distance control system can be deactivated for a longer period by
pressing and holding (for approximately 3 seconds) the parking distance control switch on the instrument panel
(the red warning light on the switch comes on). The function can be switched on again only by pressing and
holding the switch again (the red warning light on the switch goes out).
Fault finding:
In the event of a system fault, the driver will be alerted by a 5-second continuous warning sound with a
different pitch to the detection signal.Note:
The diagnostic tool statuses can be used to determine the function status (ready, detecting, suspended or
deactivated) by using status ET003 Parking distance control function (see Conformity check or the relevant
status interpretation).
