Front Electronic Module (FEM): Notes

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) represents a new generation which supersedes existing control units and their functions. As a result of the modular principle, the Front Electronic Module (FEM) can be installed in all series. 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. The aim is to reduce the number of control units and improve component networking. At the same time, the optimization of the wiring harness reduces the physical bus capacity.
