CAS: Car Access System

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

Vehicles with Front Electronic Module (FEM) or Body Domain Controller (BDC): The functions of the Car Access System (CAS) have been integrated in the Front Electronic Module (FEM) or in the Body Domain Controller.
