SUPPLEMENTAL RESTRAINT SYSTEM (SRS)-AIR BAG
The system consists of the starter switch, Diagnostic Energy Reserve Module (OERM), dual pole arming
sensor,
SRS coil assembly, inflator module (driver & passenger), forward sensor and warning light.
SRS is mainly comprised of the deployment loop and the DERM.
The main function of the deployment loop is to flow current into the inflator modules inside the steering
wheel (driver side) and the passenger side instrument panel (passenger side) to inflate the air bag. The
forward sensor
(LH and /or RH) gets activated by a shock caused by collision during running of a vehicle, the
current
from the battery flows into the inflator modules through dual pole arming sensor, so that the air bag
is
inflated.
The DERM supplies the current to the deployment loop to ensure that the air bag is inflated, if the power
circuit between battery and deployment loop is cut off by the shock of collision.
In
addition, the DERM monitors a voltage drops between components, and if the voltage drops below the
specified
value, the driver is alerted by the "AIR BAG" warning light in meter assembly.
Refer to Section 9J "SUPPLEMENTAL RESTRAINT SYSTEM (SRS)-AIR BAG" for details.

ANTENNA
AUTO ANTENNA
The auto antenna is interlocked with the radio switch.
The antenna rod goes up when the switch is turned
on, and goes
down when the switch is turned off. The
antenna rod
also goes down when the starter switch
is turned
off with the radio on.
The antenna rod goes up
or down when the cable
connected to the uppermost rod is let out or taken up
by the rotation of motor.
The
motor is provided with a built-in limit switch.
When the up/down
motion of the antenna is com­
pleted, the
limit switch is activated to cut off the
circuit. (Fig. 9A-4)

(1!] INSPECTION
Apply battery voltage to the connector terminals
of the antenna motor to check to see if the
antenna works correctly. (Fig. 9A-5)
Repair the antenna assembly
or replace it when
the results
of inspection are found abnormal.

The circuit consists of the starter switch, cruise control main switch, cruise control switch, cruise control unit,
pump &actuator, brake switch, clutch switch (M/T), mode switch (A/T), vehicle speed sensor (incorporated into
the speedometer) and indicator light.
The cruise control keeps
the vehicle running at a fixed speed until a signal canceling this fixed speed is received.
When the main switch "AUTO CRUISE" is turned on with the vehicle in the running mode, the battery voltage
is applied
to the control unit. When a signal from the control switch is input to the control unit while the vehicle
is in this state, the cruise control actuator is activated to operate the system .
.._, Also, while the system is operating, the "AUTO CRUISE" indicator light in the indicator box lights up.
1. SET /COAST SWITCH FUNCTION
1) SET function: When the SET/COAST switch
is pressed and released
with the main switch
on, the speed at
which the vehicle is running
at that moment is stored in the memory, and
the vehicle
automatically runs at the speed
stored.
2) COAST-DOWN function: When the SET/
COAST switch is kept on while the vehicle in
running, the vehicle decelerates
during that
time. The speed at which vehicle is running
when the control switch is turned off is stored
in the
memory, and the vehicle automatically
returns
to the stored speed.
3) Tap-down function: When the SET/COAST
switch is turned on and off instantaneously
while the vehicle is running, the vehicle decel­
erates a mile for each on/off operation. The
vehicle speed at
which the vehicle was run­
ning when the SET/COAST was turned off last
is stored in the
memory, and the vehicle auto­
matically returns to this stored speed.
2. RESUME/ ACCEL SWITCH FUNC­
TION
1) Resume function: When the RESUME/
ACCEL switch is turned
on/off after the system
is
temporarily deactivated by pressing the
brake or clutch pedal while the vehicle is
running,
the vehicle resumes. The speed
stored before the system
was released.
2) Accelerate function: When the RESUME/
ACCEL switch is kept on after the system is
released completely, the vehicle accelerates
its speed
during that time. The vehicle speed
at
which the vehicle was running when the
switch
was turned off is stored in the memory,
and the vehicle automatically returns to this
speed.
3) Tap-up function: When the RESU ME/ACCEL
switch is
turned on and off instantaneously
while the vehicle is running, the vehicle decel­
erates a mile for each on/off operation. The
vehicle speed at
which the vehicle was run­
ning when the switch was turned off last is
stored in the
memory, and the vehicle auto­
matically returns to this stored speed.
