Power Door Lock

General Description

The circuit consists of the door lock switch, actuator for the front passenger door, rear doors and the door lock con-
troller.
The door lock controller is always provided with battery voltage. The key or the inside lock knob on the driver’s door
can activate the lock mechanism of all the doors.
When the driver’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 controller to activate the actuator to lock and unlock the doors.

Notice:
Arrow marks indicate the direction of current.
