Footwell Module
The footwell module detects the request to switch the interior lighting on/off based on the signals from the Car Access System, for example.
The footwell module provides a number of outputs for the interior lighting functions.
| Output | Light |
|---|---|
| Doorway light | All doorway lights in the doors |
| Terminal 58g | Interior door lights, center console stow compartment, center armrest stow compartment, ambient interior lights, map pocket lights and backlighting for various switches, etc. |
| Footwell light | Footwell lights, front |
| Interior lighting 1 | Rear footwell lights, sill lights, front interior light |
| Interior lighting 2 | Interior light, rear |
| Courtesy lighting | Courtesy lights in the doors |
| Electrical equipment cutout | Reading lights |
The footwell module evaluates the status of the door contacts. The interior lighting is switched on when a door is opened. Each door switch is connected individually to the footwell module.
The footwell module analyzes the status of the front reading light buttons and front/rear interior light buttons.
