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 - Function80D
Exchanges between the lighting function components
Rain/light sensor - UCH
Functions available and operating mode
–Hazard warning lights switched on by ABS:
This function is available for all countries except Brazil, Finland, Great Britain, Japan and Sweden.
In the event of braking involving rapid deceleration, the ABS computer transmits a request to the UCH to switch on
the hazard warning lights via the multiplex network. The illumination of the hazard warning lights by the ABS is
configured using CF024 "Illumination of hazard warning lights by the ABS", and this function can be viewed
using LC018 "Illumination of the hazard warning lights by the ABS".
–See-me-home lighting:
This function is available on top of the range vehicles.
It switches on the dipped headlights for several seconds. This function is activated without using + 12 V APC by
using the "headlight flasher" several times. The See-me-home lighting function is configured using CF032 "See-me-
home lighting", and this function can be viewed using LC025 "See-me-home lighting".
–Daytime running lights:
In Scandinavian countries, when the engine is running, this function switches on the side lights and dipped
headlights without the driver switching them on. The daytime running lights function is configured using CF014
"Daytime running lights", and this function can be viewed using LC008 "Daytime running lights".
–Automatic headlighting:
This function is only available if the vehicle is equipped with a rain/light sensor.
It lights up the side lights and the dipped headlights as soon as the exterior light fades (night, tunnel, etc.).
This function is activated by turning the horn and lights switch from the OFF position to the "ON" position (side lights)
twice in succession.
This function can be configured using one of the following configurations:
–CF193 "Automatic lighting function" and can be viewed using LC095 "Automatic lighting function".
–CF194 "Automatic wiper function" and can be viewed using LC096 "Automatic wiper function".
–CF035 "Rain/light sensor" and can be viewed using LC044 "Rain/light sensor". –brightness value
