Power Locks: Description and Operation

The circuit consists of the door lock (and power window) switch, door lock actuator for the front and rear door, tailgate lock actuator and the door lock key switch.
The front door lock switch-LH is always provided with the battery voltage. The key or the inside lock button on the both driver's and the front passenger's door can activate the lock mechanism of all the doors (including the tailgate).
When the driver's door lock switch or the front passenger's door lock switch is turned on, current flows for about one second to the door lock actuator of each door connected in parallel with the front door lock (and power window) switch-LH to activate the actuator to lock and unlock the doors.
