Power Door Lock
General Description
The circuit consists of door lock (& power window)
switch, door lock actuator for front and rear door,
tailgate lock actuator and door lock key switch.
Front door lock switchÐLH is always provided with
battery voltage. The key or the inside lock button on
the both driverÕs and front passengerÕs door can
activate the lock mechanism of all the door
(including tailgate).
When driverÕs door lock switch or front passengerÕs
door lock switch is turned on, current flows for
about one second to door lock actuator of each door
connected in parallel with front door lock (& power
window) switchÐLH to activate actuator to lock and
unlock doors.
