Deployment When Disposing of Front Passenger Airbag Assembly

When disposing of the steering wheel pad/ front passenger airbag assembly only, never use the customer's vehicle to deploy the airbag.

Remove the steering wheel pad / front passenger airbag assembly from the vehicle and be sure to follow the procedure given below when deploying the airbag.

HINT: Have a battery ready as the power source to deploy the airbag.

1. REMOVE STEERING WHEEL PAD/ FRONT PASSENGER AIRBAG ASSEMBLY
When storing the steering wheel pad/ front passenger airbag assembly, keep the upper surface of the pad facing upward.

When Scrapping Vehicle:





2. FIX STEERING WHEEL PAD/ FRONT PASSENGER AIRBAG ASSEMBLY
Using a service-purpose wire harness for the vehicle, tie down the steering wheel pad/ front passenger airbag assembly.
Wire harness: Stripped wire harness section 1.25 sq. mm or more (0.0019 sq. in. or more)

HINT: To calculate the square of the stripped wire harness section
Square = 3.14 x sq. (Diameter) divided by 4.

CAUTION: If a wire harness which is too thin or some other thing is used to tie down the steering wheel pad/ front passenger airbag assembly, 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 sq. mm (0.0019 sq. in).

Steering Wheel Pad:





Steering Wheel Pad
a. Remove the connector on the steering wheel pad rear surface from the inflator cover.

Steering Wheel Pad:





b. Install the 2 bolts with washers in the 2 bolt holes in the steering wheel pad.
Bolt:
L 35.0 mm (1.378 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 difficult to turn.
^ Do not tighten the bolts too much.

Steering Wheel Pad:





c. Using 3 wire harnesses, wrap the wire harnesses 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.

Steering Wheel Pad:





d. 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 connector 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 dangerous if looseness in the wire harness results in the steering wheel pad to come off through the shock of the airbag deployment.
^ Always tie down the steering wheel pad with the pad side facing upward. It is very dangerous if the steering wheel pad is tied down with the metal surface facing upward as the wire harness will be cut by the shock of the airbag deploying and the steering wheel pad will be thrown into the air.

HINT: The disc wheel will be marked by airbag deployment, so use a redundant disc wheel.

Steering Wheel Pad:





Front Passenger Airbag Assembly
a. Wrap the wire harness around the tire, passing the wire harness through the installation holes which indicated in the illustration by arrows.

Steering Wheel Pad:





b. Position the front passenger airbag assembly inside the tire with the airbag door deployment direction facing inside.

Tire size: Must exceed the following dimensions
Width 185 mm (7.28 in.)
Inner diameter 360 mm (14.17 in.)

CAUTION:
^ Make sure the wire harness is tight. It is very dangerous if a loose wire harness results in the front passenger airbag assembly to come off due to the shock of the airbag deployment.
^ Always tie down the front passenger airbag assembly with the airbag door facing inside.

NOTICE: The tire will be marked by the airbag deployment. so use a redundant tire.

Steering Wheel Pad:





3. CONFIRM FUNCTIONING OF SST
SST 09082-00700

Steering Wheel Pad:





4. INSTALL SST AND COVER THE STEERING WHEEL PAD/ FRONT PASSENGER AIRBAG ASSEMBLY
Steering Wheel Pad

CAUTION: Place the disc wheel on level ground.

a. Connect the SST connector to the steering wheel pad connector.
SST 09082-00700

NOTICE:: To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock. Also, provide some slack for the SST wire harness inside the disc wheel.

Steering Wheel Pad:





b. Cover steering wheel pad with cardboard box or tires.
Covering Method Using Cardboard Box
Cover the steering wheel pad with the cardboard box and weigh the cardboard box down in 4 places with at least 196 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 diameter of the disc wheel with tire the steering wheel pad -
x = 460 mm (18.11 in.) + width of tire
y = 650 mm (25.59 in.)

NOTICE: If a cardboard box smaller than the size specified is used, the cardboard box will be broken by the shock of the airbag deployment.

Covering Method Using Tires:





Covering Method Using Tires
Place at least 3 tires without disc wheel on top of the disc wheel with tire to which the steering wheel pad is tied.
Tire size: Must exceed the following dimensions-
Width 185 mm (7.28 in.)
Inner diam 360 mm (14.17 in.)

CAUTION: Do not use tires with disc wheels.

NOTICE: The tires may be marked by the airbag deployment, so use redundant tires.

Covering Method Using Tires:





Front Passenger Airbag Assembly
a. Place at least 2 tires under the tire to which the front passenger airbag assembly is tied.
b. Place at least 2 tires over the tire to which the front passenger airbag assembly is tied. The top tire should have the wheel installed.

Covering Method Using Tires:





c. Tie the tires together by 2 wire harness.

CAUTION: Make sure that wire harnesses are tight. It is very dangerous it loose wire harnesses result in the tires coming free due to the shock of the airbag deploying.

HINT: Place the SST connector and wire harness inside tires. Provide at least 1 m (3 ft) of slack for the wire harness.

Covering Method Using Tires:





d. Connect the SST connector to the front passenger airbag assembly connector.
SST 09082-00700

NOTICE: To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock.

Covering Method Using Tires:





5. AIRBAG DEPLOYMENT
a. Connect the SST red clip to the battery positive (+) terminal and the black clip to the battery negative (-) terminal.
b. Confirm that no-one is within 10 m (33 ft) of the tires to which the steering wheel pad/ front passenger airbag assembly is tied.
c. Press the SST activation switch and deploy the airbag.

HINT: The airbag deploys simultaneously as the LED of the SST activation switch lights up.

6. DISPOSAL OF STEERING WHEEL PAD / FRONT PASSENGER AIRBAG ASSEMBLY

CAUTION:
^ The steering wheel pad/ front passenger airbag assembly is very hot when the airbag is deployed, so leave it alone for at least 30 Minutes after deployment.
^ Use gloves and safety glasses when handing a steering wheel pad/ front passenger airbag assembly with deployed airbag.
^ Do not apply water, etc. to a steering wheel pad/ front passenger airbag assembly with deployed airbag.
^ Always wash your hands with water after completing the operation.
a. Remove the steering wheel pad / front passenger airbag from the tire.
b. Place the steering wheel pad/ front passenger airbag assembly in a vinyl bag, tie the end tightly and dispose of it the same way as other general parts.
