Car Access System 2 (CAS2): Notes

As soon as the CAS2 receives the lock/unlock signal from the remote control receiver, it checks whether the identification transmitter is valid and belongs to the vehicle. Only if the check/authentication, which takes a few milliseconds, is successful will the CAS2 forward the request to activate the central locking.

The CAS2, serves as the master control module for the central locking system, as it issues the enable signal to activate a lock/unlock function. An enable status signal is transmitted to the JBE from CAS2 via K-CAN.

Signal Path: Remote control to remote receiver to CAS2; or 

Central lock button input to CAS2; 

Enable signal from CAS2 to JBE via K-CAN (if all doors are closed) 

Door status signal from FRM to JBE via K-CAN then JBE via K-Can to CAS2 

Example: The request to lock the vehicle, is not executed while the driver's door is open.
