The Body Domain Controller (BDC) represents a new generation superseding existing control units and their functions. 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 body domain controller (BDC) makes available 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 an independent module in the Body Domain Controller (BDC).

The Body Domain Controller (BDC) as the master control unit is responsible for the exterior lights functions. The Body Domain Controller (BDC) decides which light functions are to be activated or deactivated. For many functions, information from sensors, contacts and switches is required. The Body Domain Controller (BDC) receives the signals from the components and transmits the corresponding information to the bus users.
