Toyota Tundra Service Manual: Disposal

DISPOSAL

CAUTION / NOTICE / HINT

CAUTION:

Before performing pre-disposal deployment of any SRS component, review and closely follow all applicable environmental and hazardous material regulations. Pre-disposal deployment may be considered hazardous material treatment.

PROCEDURE

1. PRECAUTION

CAUTION:

• Never dispose of a front passenger airbag that has an unactivated 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 (32.8 ft.) away from the front passenger airbag.
• The front passenger airbag becomes 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 a front passenger airbag with a deployed airbag.
• Do not apply water to a front passenger airbag with a deployed airbag.
• Always wash your hands with water after completing the operation.
• An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with bare hands to discharge static electricity before performing this procedure.

HINT:

When scrapping a vehicle equipped with the SRS or disposing of the front passenger airbag assembly, 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 the TOYOTA MOTOR SALES, U.S.A., INC.

2. DISPOSE OF FRONT PASSENGER AIRBAG ASSEMBLY (WHEN INSTALLED IN VEHICLE)

HINT:

• Prepare a battery as the power source to deploy the airbag.

(a) Check the function of SST (see page ).

(b) Read the precaution (see page ).

(c) Disconnect the cable from the negative (-) battery terminal.

CAUTION:

Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

3. DISPOSE OF FRONT PASSENGER AIRBAG ASSEMBLY (WHEN NOT INSTALLED IN VEHICLE)

SST: 09082-00700

SST: 09082-00802

09082-10801

09082-30801

09082-40800

NOTICE:

Be sure to follow the procedure detailed below when deploying the airbag.

HINT:

• Prepare a battery as the power source to deploy the airbag.
• In this procedure, the inflator of the front passenger airbag assembly is deployed first. Next, the actuator is deployed.

(a) Check the function of SST (see page ).

(b) Remove the front passenger airbag (see page ).

CAUTION:

• When removing the front passenger airbag, work must be started 90 seconds after the ignition switch is turned OFF and the negative (-) terminal cable is disconnected from the battery.
• When storing the front passenger airbag, keep the airbag deployment side facing upward.

SST: 09082-00802 09082-10801 09082-30801 Text in Illustration *a Inflator Side *b Actuator Side (2) Connect the SST connector to the front passenger airbag assembly actuator side. SST: 09082-00802 09082-10801 09082-40800

(d) Using a service-purpose wire harness for the vehicle, tie down the front passenger airbag to the tire.

Wire harness:

Cross-sectional area of stripped wire

1.25 mm2 or more (0.00193 in.2 or more)

CAUTION:

If the wire harness is too thin or an alternative object is used to tie down the front passenger airbag, it may be snapped by the shock when the airbag is deployed. Always use a wire harness for vehicle use with an area of at least 1.25 mm2 (0.00193 in.2).

HINT:

To calculate the area of the cross-sectional area of stripped wire:

Area = 3.14 x (Diameter)2 divided by 4

(1) Position the front passenger airbag 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 (1.18 ft.)

(2) Tie the front passenger airbag to the tire with several wire harnesses.

CAUTION:

• Make sure that the wire harnesses are tight. If there is slack in the wire harnesses, the front passenger airbag may become loose due to the shock when the airbag is deployed.
• Always tie down the front passenger airbag with the airbag deployment side facing inside the tire.

NOTICE:

As the tires may be damaged by the airbag deployment, use a tire that you are planning to throw away.

(e) Place the tires.

(1) Place at least 2 tires under the tire which the front passenger airbag is tied to.

(2) Place at least 2 tires over the tire which the front passenger airbag is tied to. The top tire should have a disc wheel installed.

NOTICE:

• Do not place the SST connector under the tire because it could be damaged.
• As the disc wheel may be damaged by the airbag deployment, use a disc wheel that you are planning to throw away.
• As the tires may be damaged by the airbag deployment, use a tire that you are planning to throw away.

(3) Tie the tires together with 2 wire harnesses. CAUTION: Make sure that the wire harnesses are tight. Looseness in the wire harnesses results in the tires coming free due to the shock when the airbag is deployed.

(f) Install SST.

(g) Deploy the front passenger airbag assembly inflator.

(1) Connect the SST (09082-00700) connector to SST (09082-10801).

NOTICE:

To avoid damaging SST connector and wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for SST wire harness inside the tire.

(2) Connect the red clip of SST to the battery positive (+) terminal and the black clip of SST to the battery negative (-) terminal.

(3) Check that no one is within a 10 m (32.8 ft.) radius of the tire which the front passenger airbag assembly is tied to.

(4) Press the SST activation switch and deploy the front passenger airbag assembly inflator.

CAUTION:

When deploying the airbag, make sure that no one is near the tire.

HINT:

The airbag is deployed as the LED of the SST activation switch comes on.

(5) Disconnect the red clip of SST from the battery positive (+) terminal and the black clip of SST from the negative (-) terminal.

(6) Disconnect the SST (09082-00700) connector from SST (09082-10801).

(h) Deploy the front passenger airbag assembly actuator.

(1) Connect the SST (09082-00700) connector to SST (09080-40800).

NOTICE:

To avoid damaging SST connector and wire harness, do not lock the secondary lock of the twin lock. Also, secure some slack for SST wire harness inside the tire.

(2) Connect the red clip of SST to the battery positive (+) terminal and the black clip of SST to the battery negative (-) terminal.

(3) Check that no one is within a 10 m (32.8 ft.) radius of the tire which the front passenger airbag assembly is tied to.

(4) Press the SST activation switch and deploy the front passenger airbag assembly actuator.

CAUTION:

When deploying the airbag, make sure that no one is near the tire.

HINT:

The airbag is deployed as the LED of the SST activation switch comes on.

(i) Dispose of the front passenger airbag. CAUTION: The front passenger airbag becomes 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 a front passenger airbag with a deployed airbag. Do not apply water to a front passenger airbag with a deployed airbag. Always wash your hands with water after completing the operation. (1) Remove the front passenger airbag from the tire. (2) Place the front passenger airbag in a plastic bag, tie it tightly and dispose of it in the same way as other general parts.
