4. FAULT FINDING PROCEDURE (CONTINUED)
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.
Physical inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Ensure 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 - Role of components
Side lights:
–without automatic headlighting:
The side lights are switched on directly via the passenger compartment fuse box using the horn and
lights switch.
–with ALS: when the horn and lights switch is operated, the side lights relay is activated via the UCH
which in turn switches on the side lights via the passenger compartment fuse box.
Dipped headlights:
–without automatic headlighting: the dipped headlights are switched on directly via the passenger
compartment fuse box using the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the dipped headlights relay is activated via the
UCH which in turn switches on the dipped headlights via the passenger compartment fuse box.
Main beam headlights:
–without ALS: the main beam headlights are switched on directly via the passenger compartment fuse
box using the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the main beam headlights relay is activated via
the UCH which in turn switches on the main beam headlights via the passenger compartment fuse box.
Rear fog lights:
–without ALS: the rear fog lights are switched on directly via the passenger compartment fuse box using
the horn and lights switch.
–with ALS: when the horn and lights switch is operated, the rear fog lights relay is activated via the UCH
which switches on the rear fog lights.
Front fog lights:
–without ALS: the front fog relay is activated when the horn and lights switch is operated and the front fog
lights are switched on.
–with ALS: when the horn and lights switch is operated, the front fog lights relay is activated via the UCH
which switches on the front fog lights.
Hazard warning lights:
–the hazard warning lights are switched on using the door locking/warning switch via the UCH and the
passenger compartment fuse box.

If the horn and lights switch is a one-touch control:
Check the operation of status ET082 Rear fog lights request and command AC009
Rear fog light in the UCH. If there is a malfunction on status ET082 "Rear fog lights
request" and command AC009 "Rear fog lights", refer to the interpretation of status
ET082 "Rear fog lights request", of command AC009 "Rear fog lights" and of fault
DF109 "Rear fog lights control circuit".
Check the condition of the bulb and cleanliness of its
contacts.
Are the bulb and its contacts in good condition?
YES
Replace the light concerned.
Check that fuses F13 (10 A) and F39 (10 A) are sound and correctly fitted in the passenger compartment fuse
and relay box.
Replace the fuse if necessary.
Check the condition and connection of the light connector concerned (bent, oxidised, broken tabs).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the condition and connection of the horn and lights switch connector (tabs broken, bent, oxidised).
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V (when there is a rear fog lights request) on connection 9P of components 172 and 173. Check
