Front electronic module (FEM): Front Electronic Module

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

The Front Electronic Module (FEM) represents a new generation which supersedes existing control units and their functions. 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) provides functions from the previous control units footwell module (FRM), Car Access System (CAS), Junction Box Electronics (JBE) and central gateway module (ZGM). The central gateway module (ZGM) is installed in the Front Electronic Module (FEM) as an independent control unit.

As the master control unit, the Front Electronic Module (FEM) is responsible for the functions of the exterior lights. The front electronic module (FEM) decides which lighting functions must be activated and/or deactivated. For many functions, information from sensors, contacts and switches is required. The Front Electronic Module (FEM) receives the signals from the components and transmits the corresponding information to the bus users.
