SPEEDOMETER (FIG. 8-346)
Fig. 8-346
The speedometer is made up
of the cross coil type
ammeter (movement)
that displays indications, the
stepper
motor that drives and adds up the odometer
and
trip meter, and the driving circuit (printed circuit
board) that makes exchanges between the
pulse sig­
nals and the current.
Also, the vehicle speed sensor, which is incorporated
into the speedometer, is activated
by receiving sig­
nals (vehicle speed) detected by the vehicle speed
sensor
installed to the transmission.

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.

Supplemental Restraint System 9J-3
GENERAL DESCRIPTION
RESTRAINT DEVICES
The Supplemental Restraint System(SRS) helps
supplement the protection offered by the driver and front
passenger seat
belts by deploying an air bag from the
center of the steering
wheel and from the top of the right
side of the instrument
panel.
~ Deployed Air Bag
~ Knee Bolster
~ Seat Belt
The air bag deploys when the vehicle is involved in a
frontal crash of sufficient force up to 30 degrees off the
centerline of the vehicle. To further absorb the crash
energy there is a knee
bolster located beneath the
instrument
panel for both the driver and passenger, and
the steering
column is collapsible.

SRS COIL ASSEMBLY
The SRS coil assembly consists of two current carrying
coils. They are attached to the steering column and allow
rotation of the steering wheel while maintaining
continuous contact of the driver deployment loop to the
driver inflator module.
There is a shorting clip on the yellow
3-way connector
near the base of the steering column which connects the
SRS coil to the SRS wiring harness. The shorting clip
shorts the circuits to the
SRS coil and driver inflator
module when the yellow 3-way connector is
disconnected. The circuit to the driver inflator module is
shorted
in this way to help prevent unwanted deployment
of the air bag when servicing the steering column or other
SRS components.
INFLATOR MODULES
The inflator modules consist of an inflatable bag and an
inflator(a canister of gas-generating material and an
initiating device). When the vehicle is in a frontal crash
of sufficient force to close the dual pole arming sensor
and at least one of the discriminating sensors
simultaneously, current flows through the deployment
loops. Current passing through the initiator ignites the
material
in the inflator module. The gas produced from
this reaction rapidly inflates the air bag.
There is a shorting clip
on the driver inflator module side
of the upper steering column connector which connects
the
SRS coil assembly to the driver inflator module. The
shorting clip shorts across the driver inflator module
circuits when the upper steering column connector is
disconnected. The circuit to the driver inflator module is
shorted
in this way to help prevent unwanted deployment
of the air bag when servicing the driver inflator module,
the steering column
or other SRS components.
There is a shorting clip on the passenger inflator module
connector which connects to the passenger inflator
module jumper. The shorting clip shorts across the
passenger inflator module circuit when the passenger
inflator module connector is disconnected. The circuit to
the passenger inflator module is shorted in this way to
help prevent unwanted deployment of the air bag when
servicing the passenger inflator module, the instrument
panel or other
SRS components.
STEERING COLUMN
The steering column absorbs energy and is designed to
compress in a frontal crash to decrease the chance of
injury to the driver. A steering column reinforcement is
also used for additional support.
KNEE BOLSTER
The knee bolsters are used to absorb energy and control
the forward movement of the vehicle's front seat
occupants during a frontal crash, by limiting leg
movement.
