BMW 7 Series: System Overview

Schematic System Circuit Diagram - Interior Lighting

The system circuit diagram follows the description below and provides an overview of the full extent of all possible interior lighting options.

The status of the door contact (Hall sensor) in the lock (38) changes, for example, when the door is opened with the vehicle unlocked. The footwell module (1) evaluates the status and sends the request to switch on the interior lighting.

At the same time, the doorway light (13) for the door that is open and the footwell lights (2, 3, 46, 48) are switched on by the footwell module. The status of the door contact changes again when the vehicle door is closed. The footwell module initiates the procedure to switch off the interior lighting. If the tailgate is opened, the status of the tailgate switch (21) registered by the tailgate central locking module changes. The luggage compartment lighting (24, 53) is connected to the power supply via Terminal 30B so that the luggage compartment lights are switched on via the tailgate switch.
