Outside Mirror: E60, E61, E63, E64

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2006 BMW Z4, 2006 BMW M3, 2006 BMW M Roadster, 2006 BMW M Coupe, and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

How it works

The body-gateway module controls and monitors the functions of the outside mirrors.

Basic Outside Mirror

The body-gateway module (KGM) directly controls the components in the outside mirror. The KGM controls the mirror heating capacity automatically by means of a pulse-width modulated signal (PWM signal). The heat output is dependent on ambient temperature and wiper intensity. If the wipers are operating, the heat output is increased to ensure reliable defrosting of the mirror glass.

Outside Mirror With Extended Functions

The body-gateway module (KGM) controls the mirror electronics via the LIN-bus. The mirror electronics controls the mirror heating in connection with power semiconductors. The KGM sends information relating to the heating capacity (percentage ON time) via the LIN-bus. The heat output is dependent on ambient temperature and wiper intensity. If the wipers are operating, the heat output is increased to ensure reliable defrosting of the mirror glass.
