1996 TOYOTA T100 (RM449U)
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.
CAUTION:
For removal and installation of the steering wheel pad, see
the SR section and be sure to follow the correct procedure.
3. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
DEPLOYED
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check for the deformation on the horn button con-
tact plate of the steering wheel.
Check for the damage to the spiral cable connector
and wire harness.
HINT:
If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a steering wheel pad (with airbag), always first deploy the air-
bag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC..
When disposing of a steering wheel pad with an airbag
deployed in a collision, follow the same procedure given in step
1−(c) in ”DISPOSAL”.
CAUTION:
Never dispose of a steering wheel pad which has an
undeployed airbag.
The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out−of−
doors and where it will not create a nuisance to
nearby residents.
When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.
SST 09082−00700
When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
Use gloves and safety glasses when handling a steer-
ing wheel pad with the deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
the deployed airbag.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of SST
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082−00700
(1) Connect the SST battery.
Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (−) terminal.
HINT:
Do not connect the yellow connector which will be connected
with the supplemental restraint system.
(2) Check functioning of SST.
Press the SST activation switch, and check that the
LED of the SST activation switch lights up.
CAUTION:
If the LED lights up when the activation switch is not being
pressed, SST malfunction is probable, so definitely do not
use the SST.
(b) Install the SST.
CAUTION:
Check that there is no looseness in the steering wheel and
steering wheel pad.
(1) Disconnect the airbag connector of the spiral cable.

(2) Connect the SST connector to the airbag connector
of the spiral cable.
SST 09082−00700
(3) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(4) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(5) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the negative (−) termi-
nal.
(c) Deploy the airbag.
(1) Check that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(d) Dispose of steering wheel pad (with airbag).
CAUTION:
The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.
Use gloves and safety glasses when handling a steer-
ing wheel pad with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.
(1) When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the steering wheel pad still
installed.
(2) When moving a vehicle for scrapping which has a
steering wheel pad with deployed airbag, use
gloves and safety glasses.

2. DEPLOYMENT WHEN DISPOSING OF STEERING
WHEEL PAD ONLY
NOTICE:
When disposing of the steering wheel pad (with air-
bag) only, never use the customers vehicle to deploy
the airbag.
Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the steering wheel pad.
(See page SR−13 or SR−26)
CAUTION:
When storing the steering wheel pad, keep the upper sur-
face of the pad facing upward.
(b) Remove the steering wheel pad connector.
Remove the connector on the rear surface of the steering
wheel pad from the bracket.
(c) Fix steering wheel pad to disc wheel with tire.
(1) Install the 2 bolt with washers in the 2 bolt holes in
the steering wheel pad.
Bolt:
L: 35. mm (1.387 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)
NOTICE:
Tighten the bolts by hand until the bolts become diffi-
cult to turn.
Do not tighten the bolts too much.
(2) Using a service−purpose wire harness tie down the
steering wheel pad to the disc wheel.
Wire harness: Stripped wire harness section
1.25 mm

or more (0.0019 in2. or more).
HINT:

CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the steering wheel pad, it may be snapped
by the shock when the airbag is deployed. This is highly
dangerous. Always use a wire harness for vehicle use
which is at least 1.25 mm
2
(0.0019 in2).
(3) Using 3 wire harness, wind the wire harness at least
2 times each around the bolts installed on the left
and right sides of the steering wheel pad.
CAUTION:
Tightly wind the wire harness around the bolts so that
there is no slack.
If there is slackness in the wire harness, the steering
wheel pad may come loose due to the shock when the
airbag is deployed. This is highly dangerous.
(4) Face the upper surface of the steering wheel pad
upward. Separately tie the left and right sides of the
steering wheel pad to the disc wheel through the
hub nut holes. Position the steering wheel pad con-
nector so that it hangs downward through a hub
hole in the disc wheel.
CAUTION:
Make sure that the wire harness is tight. It is very dan-
gerous when looseness in the wire harness results in
the steering wheel pad coming free through the shock
from the airbag deploying.
Always tie down the steering wheel pad with the pad
side facing upward. It is very dangerous when the
steering wheel pad is tied down with the metal sur-
face facing upward and the steering wheel pad will be
thrown into the air.
NOTICE:
The disc wheel will be marked by airbag deployment, so
use the spare disc wheel.

NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the disc
wheel.
(2) Move the SST to at least 10 m (33 ft) away from
steering wheel pad tied down on the disc wheel.
(f) Cover steering wheel pad with cardboard box or tires.
Covering method using cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with the tire which the steer-
ing wheel pad is tied to−
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.
