BMW 7 Series: System Components
Overview
The following components are installed in the F01/F02 for the purpose of operating the outside mirrors:
- Driver's door switch cluster with
- Outside mirror adjustment switch
- Outside mirror selector switch
- LIN-bus link
- Outside mirrors
- Footwell module
- Junction box electronics
- Components for comfort/convenience function
- Car Access System
- Driver's door lock cylinder
- Remote control receiver in the diversity module.
Driver's Door Switch Cluster
The driver's door switch cluster is connected via the LIN-bus to the footwell module.
The adjustment motors in the Low version of the outside mirrors are controlled directly by the mirror adjustment switch in the driver's door switch cluster.
The driver's door switch cluster in the High version of the outside mirrors is connected to the outside mirrors via the LIN-bus.
The electronic mirror module in the outside mirrors evaluates the LIN-bus signals and activates the adjustment motors.
NOTE: The driver's door switch cluster is connected to terminal 30B, terminal 31. The driver's door switch cluster receives the status of terminal 58g from the footwell module on the LIN-bus.
Design of the Outside Mirrors
Drive unit with memory
The drive unit with memory function additionally consists of the following components:
- Electronic mirror module
- Position potentiometer
- Folding mirror motor
- LIN-bus
- Electrochromic glass.
NOTE: In combination with the Active Blind Spot Detection (Lane Change Warning) the outside mirror also contains the display for the warning.

Footwell Module
The master function for controlling the outside mirrors is integrated in the footwell module.
On vehicles with memory function, the mirror position of the respective memory button (driver's seat) is stored in the footwell module.
The outside mirrors (high) and the driver's door switch cluster are connected to the footwell module via the LIN-bus. The outside mirror functions are activated via the LIN-bus.
Junction Box Electronics The junction box electronics power the low version of the outside mirror heating system.
The signal is pulse width-modulated and has a frequency of 1 Hz.
The junction box electronics also request the status of the electrochromic interior rearview mirror on the LINbus.
The mirror electronics feed back the current status of the electrochromic interior rear-view mirror. The junction box electronics send the status to the footwell module on the K-CAN2. The footwell module is therefore aware of the status and is able to control the dimming of the outside mirrors accordingly.
