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.
