DOOR MIRROR SWITCH ASSEMBLY
(CONTROL SWITCH, FOLDING
SWITCH
AND DEFOGGER SWITCH)
(FIG. 8-305)
The door mirror switch is made up of the control
switch that controls the vertical and horizontal move­
ment of both mirrors, the folding switch, and the
defogger switch.
The control switch consists of six switches, two of
which are used to select a mirror on either the left or
the right side, and the remaining four switches control
vertical or horizontal mirror movement.
The folding switch contains two switches, and their
contacts are changed over each time these switches
are depressed. The direction of the current flow to the
motor in the mirror is controlled to perform the fold­
ing and returning action of the mirror.
When depressing the defogger switch, the defogger
indicator lights up to inform the driver that the mirror
built-in heater is operating.

Preparation: Disconnect the battery ground cable.
2. Door mirror switch assembly
Fig. 8-310
1. Front console assembly
• Remove four screws.
• Remove the transmission shift lever knob.
• Remove the transfer shift lever knob.
• Disconnect the seat heater switch connectors
(If so equipped).
• Disconnect the door mirror switch connectors.
• Disconnect the "POWER & WINTER" switch
connectors.
(A/T only)
2. Door mirror switch assembly
• To remove the switch, pushing the switch locks
from the back side of the front console.
B INSTALLATION
To install, follow the removal steps in the reverse
order, noting the
following point.
1. Depress the switch with your fingers until it locks
securely.
CHASSIS ELECTRICAL 8-267
DOOR MIRROR (FIG. 8-311)
Fig. 8-311
Mirrors contain two driving motors for the horizontal
and vertical movement of the mirror and one motor
for folding the mirror.
The movement of the mirror is controlled by the
direction
of current running through these motors.
The housing portion
ofthe mirror is provided with the
auto-stop mechanism which is
interlocked with the
motor for folding the mirror. When the mirror moves
to the stop position (with the mirror folded or returned
to its original position), the current to the motor is
shut off.
When the
mirror cannot operate due to some obstacle
and the motor stops its rotation, the resistor prevents
current
overflow.
~ INSPECTION
Operating test

8-270 CHASSIS ELECTRICAL
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.
