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 seat airbag assembly 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 airbag.
• The front seat airbag assembly 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 seat airbag assembly with a deployed airbag.
• Do not apply water to a front seat airbag assembly 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 seat 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 TOYOTA MOTOR SALES, U.S.A., INC.

2. DISPOSE OF FRONT SEAT 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.

(d) Remove the front seat (see page ).

HINT:

Keep the front seat in the cabin.

(e) Install SST.

(1) Disconnect the connector (yellow colored) from the front seat airbag assembly.

NOTICE:

When handling the airbag connector, take care not to damage the airbag wire harness.

(2) Connect SST connector to the front seat airbag assembly connector.

SST: 09082-00700

SST: 09082-00820

NOTICE:

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

(3) Install the front seat (see page ).

(4) Move SST at least 10 m (32.8 ft.) away from the vehicle front side window.

(5) Maintaining enough clearance for SST wire harness in the front side window, close all doors and windows of the vehicle.

NOTICE:

Take care not to damage SST wire harness.

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

(f) Deploy the airbag.

(1) Check that no one is inside the vehicle or within a 10 m (32.8 ft.) radius of the vehicle.

(2) Press SST activation switch and deploy the airbag.

CAUTION:

• When deploying the airbag, make sure that no one is near the vehicle.
• The front seat airbag assembly 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 seat airbag assembly with a deployed airbag.
• Do not apply water to a front seat airbag assembly with a deployed airbag.
• Always wash your hands with water after completing the operation.

HINT:

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

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

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.

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

(b) Remove the front seat airbag assembly (see page ).

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

Wire harness:

Stripped wire harness section

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 curtain shield 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 stripped wire harness section:

Area = 3.14 x (Diameter)2 divided by 4

(1) Install the 2 nuts to the front seat airbag assembly.

(2) Wind the wire harness around the stud bolts of the front seat airbag assembly as shown in the illustration.

(3) Position the front seat airbag assembly inside the tire. Tire size: Must exceed the following dimensions Width 185 mm (7.28 in.) Inner diameter 360 mm (1.18 ft.) CAUTION: Make sure that the wire harnesses are tight. If there is slack in the wire harnesses, the front seat airbag assembly may become loose due to the shock when the airbag is deployed. Always tie down the front seat airbag assembly with the airbag deployment direction 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.

(d) Install SST. (1) Connect SST connector to the front seat airbag assembly connector. SST: 09082-00820

(e) Place the tires.

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

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

NOTICE:

• Do not place 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. (1) Connect SST connector. SST: 09082-00700 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.

(g) Deploy the airbag.

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

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

(3) Press SST activation switch and deploy the airbag.

CAUTION:

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

HINT:

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

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