Front electronic module (FEM): Front Electronic Module

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The Front Electronic Module (FEM) is the central control unit in the vehicle electrical system. At the same time, the Front Electronic Module (FEM) is the gateway for the other control units. The front electronic module (FEM) safeguards functions from the following former control units:

Footwell module (FRM)
Car access system (CAS)
Junction Box Electronics (JBE).
Central gateway module (ZGM)

The central gateway module (ZGM) is integrated in the Front Electronic Module (FEM). It is seen as a control unit within the control unit, as the central gateway module (ZGM) acts as a self-sufficient control unit within the Front Electronic Module (FEM). As the master control unit, the front electronic module (FEM) is responsible for the functions of the exterior lights. It decides which lighting functions have to be activated or deactivated.

The exterior vehicle lights are automatically controlled via several input signals (e.g. from the rain/light sensor) and can be switched on or off manually via the light operating facility.
