Purpose of the System

Purpose of the system







The Car Access System (CAS) controls access to the vehicle by controlling the master functions of the central locking system. It also controls the terminal statuses (KL R, KL 15, KL 50) via the ignition/starting button. The EWS functions are also integrated into the CAS which allows for starting of the engine.

The CAS is a new development and combines the components previously installed in separate control units or systems:

- Ignition/starter switch
- Electronic vehicle immobilization (EWS)
- Functions of the central body electronics (ZKE).

The major development goals were increased convenience and a new operating concept.
