Footwell Module (FRM)

The Footwell Module (FRM) is the master control module for all exterior lighting functions.

All exterior light systems (headlights and side/parklights) are switched on and off via the light switch. Information to turn the lights on or off is supplied from the light switch directly to the FRM.

The SZL directly provides information to flash headlights, activate high beams or activate turn signal indicators to the FRM via a hard wired connection for this stalk.

In the "automatic" driving lights setting, the FRM indirectly receives information for switching the vehicle lighting on/off from the Rain Lights Sensor (RLS).

Signal path: RLS via LIN-BUS to FZD; FZD via K-CAN to FRM to headlights. 

The hazard light switch is connected directly to the FRM.
