The driver door module (DDM) receives a ground input from the driver door lock control switch to lock or unlock the doors. The DDM supplies voltage to the driver door latch to lock or unlock the driver door, and sends a network message to the smart junction box (SJB) to lock or unlock the remaining doors.

The SJB receives a ground input from the passenger door lock control switch to lock or unlock the doors. The SJB supplies voltage to the RF, LR and RR door latches to lock or unlock the doors, and sends a network message to the DDM to lock or unlock the driver door.
