BDC Body Domain Controller

The body domain controller (BDC) is the central control unit in the vehicle electrical system. At the same time, the body domain controller (BDC) is the gateway for the other control units.

The central gateway module (ZGM) is integrated into the Body Domain Controller (BDC). 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 Body Domain Controller (BDC).

The task of the central gateway module (ZGM) is to connect all bus systems. This combination allows general use of information from the individual bus systems. The central gateway module (ZGM) is able to implement various reports and speeds on other bus systems. The programming data are transferred to the vehicle by Ethernet via the central gateway module (ZGM).
