Deployment When Disposing of Steering Wheel Pad
HINT: When scrapping vehicle equipped with an SRS or disposing of a steering wheel pad (with airbag), always first deploy the airbag in accordance with the procedure described. If any abnormality occurs with the airbag deployment, contact the SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.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 operation 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 after deployment.
- Use gloves and safety glasses when handling a steering 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.
NOTE:
- When disposing of the steering wheel pad (with airbag) only, never use the customers vehicle to deploy the airbag.
- 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.
a. Remove the steering wheel pad.
CAUTION: When storing the steering wheel pad, keep the upper surface 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. Using a service-purpose wire harness, tie down the steering wheel pad to the disc wheel.
Wire harness: Stripped wire harness section 1.25 sq.mm or more (0.0019 sq.in. or more).
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 sq.mm (0.0019 sq.in).
HINT: To calculate the square of the stripped wire harness section:
Square 3.14 x sq.(diameter) divided by 4
1. Install the 2 bolts with washers in the 2 bolt holes in the steering wheel pad.
Bolt:
L: 35.0 mm (1.387 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)
NOTE:
- Tighten the bolts by hand until the bolts become difficult to turn.
- Do not tighten the bolts too much.
2. 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 slack in the wire harness, the steering wheel pad may come loose due to the shock when the airbag is deployed. This is highly dangerous.
3. 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 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 if the steering wheel pad is tied down with the metal surface facing upward as the wire harness will be cut by the shock from the airbag deploying and the steering wheel pad will be thrown into the air.
NOTE: The disc wheel will be marked by airbag deployment, so when disposing of the airbag use a redundant disc wheel.
d. Check functioning of the SST
SST 09082-00700
e. Install the SST.
CAUTION: Place the disc wheel on the level ground.
1. Connect the connectors of SST to the steering wheel pad connector.
SST 09082-00700, 09082-00760
NOTE: To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for the SST wire harness inside the disc wheel.
2. Move the SST to at least 10 m (33 ft) away from the steering wheel pad tied down on the disc wheel.
f. Cover the steering wheel pad with a cardboard box or tires.
- Covering method using a 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.)
Y = 650 mm (25.59 in.)
NOTE:
- When dimension Y of the cardboard box exceeds the diameter of the disc wheel with tire to which the steering wheel pad is tied, X should be the following size. X = 460 mm (18.11 in.) + width of tire
- If a cardboard box smaller than the specified size is used, the cardboard box will be broken by the shock from the airbag deployment.
- 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 (7.87 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION: Do not use tires with disc wheels.
NOTE: The tires may be marked by the airbag deployment, so use the redundant tires.
g. Deploy the airbag.
1. Connect the SST red clip to the battery positive (+) terminal and the black clip to the battery negative (-) terminal.
2. Check that no one is within 10 m (33 ft) area around the disc wheel which the steering wheel pad is tied to.
3. Press the SST activation switch and deploy the airbag.
HINT: The airbag deploys simultaneously as the LED of the SST activation switch lights up.
h. Dispose of the 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 after deployment.
- Use gloves and safety glasses when handling a steering 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. Remove the steering wheel pad from the disc wheel.
2. Place the steering wheel pad in a vinyl bag, tie the end tightly and dispose of it in the same way as other general parts disposal.
