13 54-pin plug connection

Structure and inner electrical connection

The Body Domain Controller (BDC) is connected to the vehicle with 10 plug connections.

To avoid confusion during connection, connector housings of the same color have different encoding. This prevents them being inserted in the wrong position inadvertently.

The input for the voltage supply of the Body Domain Controller (BDC) is a 1-pin plug connection.

Dependent on the series, in the fuse block of the Body Domain Controller (BDC) are installed e.g. fuses for the following consumers:

Central locking drive
Outside door handle electronics
Air conditioning, DSC, OBD
Powertrain of the power window regulators
Light operating facility, operating facility for the assist systems and steering column switch cluster
Left headlight driver module and right headlight driver module
Rain-light-solar-condensation sensor
