Door Mirrors

There are two door mirror versions fitted to the E83. The low version (standard) door mirrors have the following functions:

The high version (optional) door mirrors have the following functions:

All mirror functions for both exterior mirrors are controlled by the GM5RD. The GM5RD makes all decisions concerning mirror movement and passes instructions to the mirror electronics (contained in the mirrors) via the LIN bus.

Potentiometers in the mirror electronics monitor position. Current position is sent to the GM5RD on a cyclical basis, and last mirror position is stored in the GM5RD.

The mirror switch in the SBFA communicates with the GM5RD via the LIN bus.
