Door Lock/Unlock

When the RFA module receives a valid command transmission to Lock/Unlock the doors it sends a signal over the Class 2 Data Link to the Drivers Door Module (DDM) to perform the appropriate function. The DDM will retransmit the command to the Passenger Door Module and Rear Door Modules over CKT 271, the Simple Bus Interface (SBI). Refer to Power Door Locks for the door module communications description. Power Locks
