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.

Fault finding - Function
Layout of the lighting function
The lighting function is provided by the computer: UCH. This computer is connected via a wire connection.
The UCH interprets the driver's requests via the steering column switch and from the rain/light sensor, and then
sends lighting function requests.
These requests are controlled by the UCH.
The UCH also controls the interior lights (courtesy lights, air conditioning operating light, central door locking
operating light).
