Front parking lamps
Parking lamps (10/11-12) light when:
- the knob in the light switch module (LSM) (3/111) is in the low beam position
- the knob in the light switch module (LSM) is in the parking lamp position
- low beam is lit via the low beam automatic function.
The lamp switch module (LSM) transmits data using serial communication to the central electronic module (CEM) (4/56) to activate the lamps.
The lamps are supplied with power via a relay which is activated by the central electronic module (CEM). The front parking lamps have a direct power supply.
The rear parking lamps and license plate lighting are powered by the rear electronic module (REM).
There is a Limp Home function for the parking lamps so that they will work even if there is a fault in the control area network (CAN) or in the serial communication between the light switch module (LSM) and the central electronic module (CEM).
