AUDIO, AUTO ANTENNA, CIGARETTE LIGHTER AND DIGITAL CLOCK
GENERAL DESCRIPTION
The audio circuit is designed for the current to flow through the receiver circuit when the radio switch is turned
on
with the starter switch in" ACC" or "ON". Current runs through the memory circuit of the audio regardless
of the position of the starter switch.
The radio antenna operates in connection
to the radio switch. The antenna rod goes up when the switch is on
and goes
down to be stored in the fender with the switch off. The antenna rod also goes down when the starter
switch is turned
off with radio on.
Refer
to Section 9A "RADIO" for details.
When the cigarette lighter is pushed in
with the starter switch at either "ACC" or "ON" position, a circuit is
formed in the cigarette lighter case
to heat the lighter coil. The cigarette lighter is sprung back to its original
position after the lighter coil
is heated.

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
Apply battery voltage to the harness side connector
I B-ssl and I B-561 of the door mirror switch and check
its function. (Fig.8-312)

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.
