The door lock knob switch and the door lock actuator are built into the door latch of each door. The door lock knob switch detects the lock and unlock states of the lock mechanism.
The door lock actuator moves the lock mechanism back and forth between the lock and unlock position. The actuator receives lock and unlock commands from the MICU.
The driver's door key cylinder switch is included in the driver's door latch. In conjunction with the key cylinder, it detects the lock/unlock of the key cylinder.

The MICU receives an lock/unlock signal from the B-CAN, then the MICU outputs a signal to the tailgate lock actuator, and the tailgate lock actuator lock/unlocks the tailgate latch.
The tailgate latch switch is the ON/OFF switch that detects the opening/closing of the tailgate. If the tailgate lock actuator is abnormal, the tailgate may be opened manually with the release lever.

The MICU receives an ON signal from the tailgate outer handle, then the MICU outputs a signal to the tailgate release actuator, and the tailgate release actuator unlocks the tailgate latch. The tailgate latch switch is the ON/OFF switch that detects the opening/closing of the tailgate. If the tailgate release actuator is abnormal, the tailgate may be opened manually with the release lever.
