DOOR LOCK ACTUATOR (FOR ALL
DOORS INCLUDING TAILGATE)
Receiving the forward or reverse current from the
front door lock (& power window) switch-LH, the
door lock actuator locks or unlocks the door with the
rod connected
to the door lock mechanism. (Fig. 8-
192)
Fig. 8-192
~ INSPECTION OF THE DOOR LOCK
ACTUATOR
Apply the battery voltage to the connector
terminals
of the door lock actuator to check the
operation. (Fig. 8-193)
When the
door lock actuator is checked on the
vehicle and there is no continuity, and when the
door lock actuator itself is checked and no
trouble is found, check the circuit between the
door lock actuator and the front door lock (&
power window) switch-LH for any failure.

ANTI-THEFT SYSTEM
GENERAL DESCRIPTION .......
The circuit consists ofthe starter switch, anti-theft controller, 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 (MfT),
ANTI-THEFT indicator light and mode switch (AfT). The system operates as
follows: After locking the starter switch and removing the starter key (this sets the alarm),
ifthe 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.
