Gateway in the BDC
The central gateway module (ZGM) is integrated in the BDC. It is a control unit within a control unit.
The task of the ZGM is to connect all the data bus systems to each other. By connecting them in this way, it is possible to use information from the individual bus systems on a generalized level. The central gateway module is able to implement different protocols and speeds on other bus systems.
The programming data for the control units is transmitted by Ethernet to the vehicle via the ZGM.

The BDC is the gateway for the following components at the local interconnect network bus:
- Exterior mirror, left and right
- Switch block, driver's door, front passenger door
