CAS: Car Access System

The CAS is the master control unit for the power windows. Following a request from the CVM, the CAS ensures that the side windows are opened or closed as the case may be. The CAS also prevents opening of the luggage compartment lid and any power windows movement with the soft top in an intermediate setting.

The Car Access System (CAS) controls convenience opening of the soft top. The signals from the remote key are received by the FBD receiver and directed to the CAS (not at present available for Comfort Access). Convenience opening and convenience closing via the lock cylinder in the driver's door: the CAS receives the signal from the footwell module (FRM).
