DISPOSAL
HINT: When scrapping a vehicle equipped with SRS or disposing of the front passenger airbag assy, be sure to deploy the airbag first 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.
CAUTION:
Never dispose of the front passenger airbag assy that has an undeployed airbag.
The airbag produces an exploding sound when it is deployed, so perform the operation outdoors 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.
When deploying the airbag, perform the operation at least 10 m (33 ft) away from the front passenger airbag assy.
The front passenger airbag assy is extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
Use gloves and safety glasses when handling the front passenger airbag assy with the deployed airbag.
Do not apply water, etc. to the front passenger airbag assy with the deployed airbag.
Always wash your hands with water after completing the operation.
1. DISPOSE OF FRONT PASSENGER AIRBAG ASSY (WHEN INSTALLED IN VEHICLE)
HINT: Prepare a battery as the power source to deploy the airbag.
Check the function of the SST.
Precaution
Disconnect the battery negative terminal.
Remove the front scuff plate
Remove the cowl side trim sub−assy
Remove the instrument panel under cover sub−assy No.1
Remove the glove compartment door pad
Remove the instrument panel sub−assy lower
i. Install the SST.
1. Disconnect the connectors from the front passenger airbag assy.
NOTICE: When handling the airbag connector, take care not to damage the airbag wire harness.
2. Connect the connector of the SST to the front passenger airbag assy.
SST 09082−00700, 09082−00780
NOTICE: To avoid damaging the SST connector and wire harness, do not lock the secondary lock of the twin lock.
Move the SST at least 10 m (33 ft) away from the vehicle front side window.
Maintaining enough clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.
NOTICE: Take care not to damage the SST wire harness.
5. Connect the red clip of the SST to the battery positive (+) terminal and the black clip of the SST to the negative (−) terminal.
j. Deploy the airbag.
Check that no one is inside the vehicle or within a 10 m (33 ft) radius of the vehicle.
Press the activation switch of the SST and deploy the airbag.
HINT: The airbag is deployed as the LED of the SST activation switch comes on.
CAUTION:
The front passenger airbag assy is extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
Use gloves and safety glasses when handling the front passenger airbag assy with the deployed airbag.
Do not apply water, etc. to the front passenger airbag assy with the deployed airbag.
Always wash your hands with water after completing the operation.
2. DISPOSE OF FRONT PASSENGER AIRBAG ASSY (WHEN NOT INSTALLED IN VEHICLE)
NOTICE:
When disposing of the front passenger airbag assy, never use the customer’s vehicle to deploy the airbag.
Be sure to follow the procedure detailed below when deploying the airbag.
HINT: Prepare a battery as the power source to deploy the airbag.
Check the function of the SST
Remove the front passenger airbag assy.
CAUTION:
When removing the front passenger airbag assy, work must be started 90 seconds after the ignition switch is turned to the ”LOCK” position and the negative (−) terminal cable is disconnected from the battery.
When storing the front passenger airbag assy, keep the upper surface of the airbag deployment side facing upward.
c. Using a service−purpose wire harness for the vehicle, tie down the front passenger airbag assy to the tire.
Wire harness: Stripped wire harness section 1.25 mm2 or more (0.0019 in.2 or more)
CAUTION: If a wire harness which is too thin or an alternative object is used to tie down the front passenger airbag assy, 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 has a section of at least 1.25 mm2 (0.0019 in.2).
HINT:
To calculate the square of the stripped wire harness section: Square = 3.14 x (Diameter)2 divided by 4
Position the front passenger airbag assy inside the tire with the airbag deployment side 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 that the wire harness is tight. It is highly dangerous when looseness in the wire harness results in the front passenger airbag assy coming free due to the shock from the airbag deployment.
Always tie down the front passenger airbag assy with the airbag deployment side facing inside the tire.
NOTICE: The tire will be marked by the airbag deployment, so use a redundant tire.
d. Install the SST.
After connecting the SST below to each other, connect them to the front passenger airbag assy.
SST 09082−00802 (09082−10801, 09082−30801)
e. Place the tires.
Place at least 2 tires under the tire to which the front passenger airbag assy is tied.
Place at least 2 tires over the tire to which the front passenger airbag assy is tied. The top tire should have the disc wheel installed.
NOTICE: Do not place the SST connector under the tire because the SST connector could be damaged.
3. Tie the tires together with 2 wire harnesses.
CAUTION: Make sure that the wire harness is tight. It is very dangerous when looseness in the wire harness results in the tires coming free due to the shock from the airbag deployment.
f. Install the SST.
Connect the connector of the SST.
SST 09082−00700
NOTICE: 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 tire.
g. Deploy the airbag.
Connect the red clip of the SST to the battery positive (+) terminal and the black clip of the SST to the battery negative (−) terminal.
Check that no one is within a 10 m (33 ft) radius of the tire to which the front passenger airbag assy is tied.
Press the activation switch of the SST and deploy the airbag.
HINT: The airbag is deployed as the LED of the SST activation switch comes on.
h. Dispose of the front passenger airbag assy.
CAUTION:
The front passenger airbag assy is extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.
Use gloves and safety glasses when handling the front passenger airbag assy with the deployed airbag.
Do not apply water, etc. to the front passenger airbag assy with the deployed airbag.
Always wash your hands with water after completing the operation.
Remove the front passenger airbag assy from the tire.
Place the front passenger airbag assy in a plastic bag, tie it tightly and dispose of it in the same way as for other general parts disposal.
