General
The rear fog light identifies the rear area of the vehicle in poor weather conditions. The rear fog light is operated via the rear fog light button on the exterior lighting switch.
Function requirement
- Low beam or daytime running lights on
Function
The exterior lighting control unit (depending on given vehicle, either the signal acquisition and actuation module or the front and rear signal acquisition and actuation modules) actuates the rear fog light itself or requests its actuation. This takes place depending on the network architecture of the vehicle.
Vehicles with trailer hitch
The rear fog light on the vehicle is not actuated during trailer operation. Instead, the rear fog light on the trailer is actuated. The exterior lighting control unit requests actuation of the rear fog light on the trailer. The trailer recognition control unit implements this request.
