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 lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag.
  • The lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag with a deployed airbag.
  • Do not apply water, etc. to a lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag, 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 distributor.

2. DISPOSE OF LOWER NO. 1 INSTRUMENT PANEL 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 disable the SRS system.

(d) Remove the lower No. 1 instrument panel airbag (See page ).

(e) Install SST.

(1) Connect SST connector to the lower No. 1 instrument panel airbag.

SST: 09082-00700

SST: 09082-00780

NOTICE:

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

(2) Install the lower No. 1 instrument panel airbag (See page ).

NOTICE:

Take care not to damage SST wire harness.

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

(4) 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.

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

CAUTION:

  • When deploying the airbag, make sure that no one is near the vehicle.
  • The lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag with a deployed airbag.
  • Do not apply water to a lower No. 1 instrument panel airbag 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 LOWER NO. 1 INSTRUMENT PANEL 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 lower No. 1 instrument panel airbag (See page ).

CAUTION:

  • When removing the lower No. 1 instrument panel airbag, wait at least 90 seconds after the ignition switch is turned off and the cable is disconnected from the negative (-) battery terminal before starting work.
  • When storing the lower No. 1 instrument panel airbag, keep the airbag deployment side facing upward.

(c) Using a service-purpose wire harness for the vehicle, tie down the lower No. 1 instrument panel airbag to a tire.

Cross-sectional area of stripped wire harness section:

1.25 mm2 or more (0.00192 in.2 or more)

CAUTION:

If the wire harness is too thin or an alternative object is used to tie down the lower No. 1 instrument panel airbag, it may be snapped by the shock when the airbag is deployed. Always use a wire harness for vehicle use with a cross-sectional area of at least 1.25 mm2 (0.00192 in.2).

HINT:

To calculate the cross-sectional area of the stripped wire harness section: Cross-sectional area = 3.14 x (Diameter)2 / 4

(1) Position the lower No. 1 instrument panel airbag inside a 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 (14.2 in.)

(2) Tie the lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag may become loose due to the shock when the airbag is deployed.
  • Always tie down the lower No. 1 instrument panel airbag with the airbag deployment side facing inside the tire.

NOTICE:

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

(d) Connect SST connector to the lower No. 1 instrument panel airbag.

SST: 09082-00780

(e) Place tires.

(1) Place at least 2 tires under the tire which the lower No. 1 instrument panel airbag is tied to.

(2) Place at least 2 tires over the tire which the lower No. 1 instrument panel airbag is tied to. The top tire should have a disc wheel installed.

NOTICE:

  • Do not place SST connector under the tires 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 tires 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) 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 tires.

(g) Deploy the airbag.

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

(2) Check that no one is within a 10 m (32.8 ft.) radius of the tire which the lower No. 1 instrument panel airbag is tied to.

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

CAUTION:

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

HINT:

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

(h) Dispose of the lower No. 1 instrument panel airbag.

CAUTION:

  • The lower No. 1 instrument panel 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 lower No. 1 instrument panel airbag with a deployed airbag.
  • Do not apply water to a lower No. 1 instrument panel airbag with a deployed airbag.
  • Always wash your hands with water after completing the operation.

(1) Remove the lower No. 1 instrument panel airbag from the tire.

(2) Place the lower No. 1 instrument panel airbag in a plastic bag, tie it tightly and dispose of it in the same way as other general parts.
