Power Door Lock System
General Description
The circuit consists of the door lock (& 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 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 (&
power window) switch ±LH to activate the actuator to lock
and unlock the doors.
