Normal Operation
When the driver door lock cylinder is turned once to either lock or unlock position, the driver set/reset switch grounds either circuit 31S-AA78 (BK/BU) for the lock command or circuit 31S-AA79 (BK/WH) for the unlock command through circuit 31-AA58 (BK) to the driver door module (DDM). The DDM will lock and unlock the driver door. When a global lock/unlock command is requested through driver door lock cylinder, the driver set/reset switch grounds either circuit 31S-AA78 (BK/BU) for the lock command or circuit 31SAA79 (BK/WH) for the unlock command through circuit 31-AA58 (BK) to the driver door module (DDM). The DDM will lock or unlock the driver door and send an SCP message to the rear electronic module (REM) to lock/unlock the passenger doors.
