Layout of the lighting function
The interior lighting function (courtesy lights, air conditioning indicator light, central door locking indicator light, etc.)
and the signalling function are provided by the UCH computer. This computer is connected via a wire connection.
The UCH interprets the driver's intention via the steering column switch, then transmits the lighting requests.
These requests are controlled by the UCH.
The exterior lighting is controlled directly by the steering column switch.
