Central locking system: Notes
The Body Domain Controller (BDC) is the master control unit for the central locking system.
The body domain controller (BDC) is the central control unit in the body electronics. The Body Domain Controller is installed in the passenger's side footwell. The central gateway module (ZGM) is a virtual independent module integrated in the Body Domain Controller (BDC).
The Body Domain Controller (BDC) is a newly developed control unit with many integrated functions. 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.
The central locking system has many special features:
- Central locking drive on the engine compartment lid with engine compartment lid contact switch
- Bonnet button
- Respectively 2 door contacts on the rear doors
NOTE:
For vehicles with range extender, the fuel filler flap does not have a conventional central locking drive. The actuator drive for the fuel filler flap is activated by the hybrid pressure refuelling electronic control unit (TFE).
