Door mirrors

There are 2 versions of the switch block in the driver's door:

• Switch block in the driver's door, basic variant

  The switch block sends its signals directly to the footwell module (FRM).

• Switch block in driver's door, High variant

  The switch block is connected to the LIN bus. The requests to adjust the mirror are sent via the LIN bus. The footwell module (FRM) receives and processes the signals via the LIN bus.

  The footwell module scans for requests from the driver's door High switch block every 20 milliseconds. In sleep mode, the power supply is disconnected. The exterior mirrors cannot be actuated.

  The mirror heating is controlled by the footwell module. The corresponding signal is fed via the LIN bus to the electronic evaluation unit in the mirror.

  If a mirror memory is fitted, the footwell module will store the memory position of the mirrors.
