refer to “INSPECTION”
Caution
Dispose of an air bag module only according to the
specified procedure. (Refer to
(2) Connect the battery terminal.
(3) Connect the scan tool to the data link connecto r, then
check diagnostic codes.
Caution
Turn the ignition switch off before disconnecting o r
connecting the scan tool.
(4) Turn the ignition key to the “ON” position.
(5) Conduct diagnostic test mode using the scan too l to, en-
sure entire SRS operates properly, except open circuit

Caution
Wait at least 60 seconds after disconnecting the ba t-
tery cable before doing any further work.
(Refer to
CLOCK SPRING INSTALLATION
Align the mating marks of the clock spring, and, after turning
the front wheels to the straight-ahead position, install the
clock spring to the column switch.
Mating Marks Alignment
Turn the clock spring clockwise fully, and then tur n back it
approx. 3 turns counterclockwise to align the mating marks.
Caution
If the clock spring’s mating marks are not aligned,
the steering wheel may not be completely
a turn, or the flat cable within the clock spring m ay be
severed, obstructing normal operation of the SRS.
STEERING WHEEL INSTALLATION
(1) Before installing the steering wheel, be sure t o first turn
the vehicle’s front wheels to the straight-ahead po sition
and align the mating marks of the clock spring.
Caution
Be sure when installing the steering wheel, that th e
harness of the clock spring does not become caught
or tangled.
(2) After installing, turn the steering wheel’
‘the way in
both directions to confirm that steering is normal.

Caution
Never attempt to measure the circuit resistance of the
air bag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with
accidental air bag deployment will result in seriou s per-
sonal injury.
(1) Check pad cover for dents, cracks or deformation.
(2)Check the air bag module for dents, cracks or defor mation.
(3) Check hooks and connectors for damage, terminal s for
deformation, and harness for binds.
(4) Check air bag inflator case for dents, cracks o r deforma-
tion.

SRS Air Bag Module Disposal,. Procedures
AIR BAG MODULE DISPOSAL PROCEDURES 52499120999
Before either disposing of a vehicle equipped with
an air bag, or prior to disposing of the air bag ule, be sure to first follow the procedures describ ed
below to deploy the air bag.
A I R
Caution
1.If the vehicle is to be scrapped, or otherwise disp osed
of, deploy the air bag inside the vehicle. If the v ehicle
will continue to be operated and only the air bag m od-
ule is to be disposed of, deploy the air bag outside
the vehicle.
2. Since a large amount of smoke is produced when the air bag is deployed, select a well-ventilated s ite.
Moreover, never attempt the test near a smoke senso r.
3. Since there is a loud noise when the air bag is
deployed, avoid
areas whenever possible.
If anyone is nearby, give warning of the impending
noise.
4.Suitable ear protection be worn by personnel
performing these procedures or by people in the im-
mediate area.
DEPLOYMENT INSIDE THE VEHICLE
(when disposing of a vehicle)
(1) Open all windows and doors of. the vehicle. Mov e the
vehicle to an isolated spot.
(2)Disconnect the negative and positive battery cables
from the battery terminals, and then remove the bat tery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
tery cables before doing any further work.

(3) Remove the steering column cover lower.
(4) Remove the connection between the clock spring
connector (red) and the body wiring harness connect or.
NOTE
the clock spring connector is disconnected from th e
body wiring harness, both electrodes of the clock s pring
connector will be automatically shorted to prevent unin-
tended deployment of the air bag due to static elec tricity,
etc.

NOTE
If the air bag module (front passenger’s side) connector
is disconnected from the body wiring harness, both elec-
trodes of the air bag module (front passenger’s side)

Connect two wires,each six meters (20 feet) long or
more, to the two leads of SRS AIR BAG ADAPTER HAR-
NESS A and cover the connections with insulation ta pe.
The other ends of the two wires should be connected
to each other (short-circuited), to prevent sudden unex-
pected deployment of the air bag.
(8) Connect the clock spring
connector (red) to SRS
air bag adapter harness A and pass the deployment w ires
out of the vehicle.
(9) Connect the SRS air bag adapter harness A to th e
connector (red) of the air bag module (front passengers

from the vehicle) to deploy the air bag.
Caution
1.Before deploying the air bag in this manner,
check to sure that there is no one near
the vehicle. Wear safety goggles,

Caution
Leave some space below the wheel for the adaptor
harness. If there is no space, the reaction when th e
air bag deploys could damage the adaptor harness.
4. Place three old tires, without wheels, on top of the tire
secured to the air bag module.

1.Connect the deployment wires to the SRS air bag ada ptor
harness A, pass it beneath the tire and wheel
and connect it to the air bag module.
2.Pass the thick wires into the hole of the air bag m odule
bracket, and secure it to the wheel of the old tire with
wheel (4 locations), with the air bag facing upward s.
Caution
1.Leave some space below the wheel for the deploy-
ment wires.
If there is no space, the reaction of the air bag
deployment could result in damage of the adaptor
harness.
2. While deployment takes place, do not have the connector of the

At alocation as far away from the air bag as
possible, and from a shielded position, if possible , discon-
nect the two connected wires from each other and co nnect
them to the two terminals of- the battery (removed from
the vehicle) to deploy the air bag.
Caution
1. Before deployment, check carefully to be sure that no one is nearby.
2.The inflator will be quite hot immediately followin g’

3. If the air bag module fails to deploy when the
procedures above are followed, do not go near
the module. Contact the MMSA Tech. Line.
5.Dispose of the air bag module after according
to the Deployed Air Bag Module Disposal Procedures (Refer to
DEPLOYED AIR BAG DISPOSAL
After deployment, the air bag module should be
of in the same manner as any other scrap parts, exc ept
the following points should be carefully noted during disposal.
(1) The inflator will be quite hot immediately foll owing
ment, so wait at least 30 minutes to allow it to co ol before
attempting to handle it.
(2) Do not put water or oil on the air bag after de ployment.
(3) There may be, adhered to the deployed air bag module,
material that could irritate the eyes
skin, so wear
gloves and safety goggles when handling a deployed
air bag module. IF DESPITE THESE PRECAUTIONS,
THE MATERIAL DOES, GET INTO
OR ON
THE SKIN, IMMEDIATELY RINSE THE AFFECTED AREA
WITH A LARGE AMOUNT OF CLEAN WATER. IF ANY
IRRITATION DEVELOPS, SEEK ATTENTION.
(4) Tightly seal the air bag module in a strong pla stic bag
for disposal.
(5) Be sure to always wash your hands after this
operation.
