Parking lights, detailed description: Notes
The parking lights can be lit together with main/dipped beam or by themselves. The parking lights are lit when the light switch is in position 1 if the ignition is on. The parking lights are on in other light switch positions depending on the programming alternative selected.
The lamps in the rear light clusters are supplied PWM-regulated voltage.
The vehicle parking lights consist of the following lamps:
- One lamp (13) in each headlamp. Power is supplied to the lamps from the Underhood Electrical Center, UEC (342).
- US only: Side marker lights (234FL/FR) in the bumper shell on both sides. Power is supplied to the lamps from the Underhood Electrical Center, UEC (342).
- Two lamps (13) in each rear light cluster (418RL/RH). Power is supplied to the lamps from the Rear Electrical Center, REC (701).
- Two lamps (15) for number plate lighting. Power is supplied to the lamps from the Rear Electrical Center, REC (701).
BCM (707) uses pins A29 and A30 to determine which position is set. BCM (707) pin A29 is connected to light switch pin 4, which corresponds to position 0. BCM (707) pin A30 is connected to light switch pin 2, which corresponds to position 2. BCM (707) sends a bus message with information on light switch position. UEC and REC use this bus message to determine if parking lights should be lit based on the programming alternative selected. For more information on bus messages, see PARKING LIGHTS, BUS INFORMATION .
The parking lights can be lit together with the headlamps or by themselves, regardless of the position of the ignition switch.
