BDC Body Domain Controller: Notes

The Body Domain Controller controls the interior lighting and the exterior lights. In the event of an accident with the corresponding severity, the interior lighting and hazard warning lights switch on automatically.

The Body Domain Controller provides input signals for terminal voltages (such as Terminal 15 wake-up wire ON). The Body The main Controller supplies voltage to the Crash Safety Module (ACSM) (starting at Terminal 30B ON).

The Body Domain Controller represents a new generation superseding existing control units and their functions. For example, the Body Domain Controller safeguards functions from the following former control units:

• FRM: Footwell module
• CAS: Car Access System
• JBE: Junction Box Electronics
• ZGM: Central gateway module

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