FRM: Footwell module

All functions of the exterior lights are controlled by the footwell module.

If the driving light is activated, the positioning lights light up. The request transmits the footwell module via a bus signal to the night vision electronics (NVE). The NVE transmits the control signals to the control units for left-hand targeted illumination (GZAL) and right-hand targeted illumination (GZAR). Both of the control units (GZAL and GZAR) turn on the in-series-connected light-emitting diodes of the positioning light in the headlights.

Vehicles with Body Domain Controller (BDC): The functions from the footwell module (FRM) were integrated into the Body Domain Controller (BDC).
