CAS: Car Access System
The CAS monitors the central locking system. The CAS control unit is the master control unit for all functions run by Comfort Access. The CAS forwards the signals on the K-CAN to the junction box electronics (JBE).
The CAS also delivers the following signals:
- Status of engine compartment lid (open or closed)
- Status of convenient opening/convenient closing
- Authentication by the CAS as protection against manipulations
- Terminal status of terminal R or terminal 15
