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.

Anti-theft System

General Description

The circuit consists of the starter switch, anti-theft &
keyless entry control unit, anti-theft horn, front door and
tailgate key switch (detect and tamper switch), door lock
(& power window) switch, door lock actuator for each
door, engine hood switch, clutch start switch (M/T),
ANTI-THEFT indicator light and mode switch (A/T).
The system operates as follows: After locking the starter
switch and removing the starter key (this sets the alarm),
if the door is unlocked in any way other than with the
proper key, the headlights start flashing, the horn sounds,
and the starter circuit is disabled.  (However, the engine
hood and all the doors must be locked and closed.)
Once the system has been placed in the warning or alarm
condition, it can be released only when the starter switch
is shifted from “OFF” to “ACC” by the starter key, or when
the lock of the front door or the tailgate is released (to
activate the detect switch) by the starter key.
