tor to the ground, check to see if the oil pressure
warning light lights up.
When the
light will not light up, check the circuit
between the meter and the oil pressure switch,
and repair
an open circuit if necessary.
FUEL TANK UNIT
The tank unit varies the internal resistance according
to the float position (fluid level) to operate the fuel
meter needle.
It is also designed
to warn the driver of low fuel level
by illuminating the fuel warning light. (Fig. 8-380)

BRAKE WARNING LIGHT
Fig. 8-384
The brake
warning light is connected in series with the
parking brake switch
installed to the parking brake
lever bracket. The
light comes on when the parking
brake lever is
pulled, and goes out when the parking
brake lever is
fully released. (Fig. 8-384)
Fig. 8-385
The brake warning
light switch, connected in parallel
with the brake fluid warning light, is designed to turn
on the brake warning light when the brake fluid in the
tank gets
below the specified level. (Fig. 8-385)
CHASSIS ELECTRICAL 8-333

The parking brake indicator light illuminates to
warn the driver that the parking brake is on. This
light does not indicate the condition of the oper­
ability of the parking brake.

the starter switch "ON".
Check the bulb or the harness when the result of
inspection is found abnormal.

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.
