Seat Adjustment
The driver operates the seat adjustment switch. The command is processed by the switch block and passed via a 3-core data line to the Center Console Control Center Module (BZM). The BZM places the message on the K-CAN S for the Car Access System (CAS).
The CAS passes the message on in its role as "gateway control unit" to the driver's seat module (SMFA) via the K-CAN P. The seat module activates the required seat adjustment motor via its output stages.
