STEERING PAD DISPOSAL

CAUTION / NOTICE / HINT

CAUTION:

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

PROCEDURE


  1. PRECAUTION

    CAUTION:


    • An airbag or pretensioner may be activated by static electricity. To prevent this, be sure to touch a metal surface with your bare hands to discharge static electricity before performing this procedure.

    • Never dispose of a horn button assembly with 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 (32.8 ft.) away from the horn button assembly.

    • The horn button 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 horn button assembly with a deployed airbag.

    • Do not apply water etc. to a horn button assembly with a deployed airbag.

    • Always wash your hands with water after completing the operation.

    Tech Tips

    When scrapping a vehicle equipped with an SRS or disposing of the horn button 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 distributor.

  2. DISPOSE OF HORN BUTTON ASSEMBLY (When not Installed in Vehicle)

    Note

    Be sure to observe the following procedure when deploying the airbag.

    Tech Tips

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


    1. Remove the horn button assembly Click here.

      CAUTION:


      • Before removing the horn button assembly, wait at least 90 seconds after turning the ignition switch off and disconnecting the cable from the negative (-) battery terminal.

      • When storing the horn button assembly, keep the airbag deployment side facing upward.

    2. A004IMPE01

      Using braided wire, tie down the horn button assembly to an unneeded wheel.

      Wire
      Stripped wire section
      1.25 mm2 (0.0019 in.2) or more

      CAUTION:

      If the wire harness is too thin or an alternative object is used to tie down the horn button assembly, it may snap when the airbag is deployed. Always use a wire for vehicle use with an area of at least 1.25 mm2(0.0019 in.2).

      Tech Tips

      To calculate the area of the stripped wire section:

      Area = 3.14 x (Diameter)2/ 4


      1. A004HNDE02
        Text in Illustration
        *a 2 times or more

        Wind 3 wires at least 2 times each around each of the snap pins.

        CAUTION:


        • Tightly wind the wires around the snap pins without any slack.

        • Make sure that the wires are tight. If there is slack in the wires, the horn button assembly may break loose when the airbag is deployed.

      2. A004IAP

        Face the airbag deployment side of the horn button assembly upward on top of an unneeded tire and wheel set. Separately tie the each sides of the horn button assembly to the wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the wheel.

        Minimum tire size
        Width
        185 mm (7.28 in.)
        Inner diameter
        360 mm (1.18 ft.)

        CAUTION:


        • Make sure that the wires are tight. If there is slack in the wires, the horn button assembly may break loose when the airbag is deployed.

        • Always tie down the horn button assembly with the airbag deployment side facing upward.

        Note

        The tire and wheel may be damaged by the airbag deployment, so use unneeded tire and wheel.

    3. Install SST.


      1. A004HGRE02

        *a Connect the clip and terminal

        Connect the clip and terminal of SST.

        SST
        09082-18010

        CAUTION:

        Place the wheel on level ground.

      2. Connect the SST connector.

        Note

        To avoid damaging the SST connector or 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.

      3. A004HSGE02
        Text in Illustration
        *a 10 m (32.8 ft.) or more

        Move SST at least 10 m (32.8 ft.) away from the airbag tied down to the wheel.

    4. Cover the horn button assembly (Using a cardboard box).


      1. A004J2ZE02
        Text in Illustration
        *1 Weight

        Cover the horn button assembly with a cardboard box.

      2. Place weights on the cardboard box in 4 places totaling at least 190 N (19 kg, 42.7 lb).

        Minimum cardboard box size
        Must exceed the following dimensions
        X
        460 mm (1.51 ft.)
        Y
        650 mm (2.13 ft.)

        Note


        • When dimension Y of the cardboard box exceeds the diameter of the wheel and tire to which the horn button assembly is tied, X should be the following size.

          X = 460 mm (1.51 ft.) + width of tire

        • If a cardboard box smaller than the specified size is used, it may be broken by the shock from the airbag deployment.

    5. Cover the horn button assembly (Using tires).


      1. A004JGOE01
        Text in Illustration
        *1 Tires (3 or more)
        *a Inner Diameter
        *b Width

        Place at least 3 tires without wheels onto the wheel and tire to which the horn button assembly is tied.

      2. Place a wheel and tire on top.

        Minimum tire size
        Width
        185 mm (7.28 in.)
        Inner diameter
        360 mm (1.18 ft.)

        CAUTION:

        Do not use tires with wheels except for on the top and bottom.

        Note


        • The tires may be damaged by the airbag deployment, so use unneeded tires.

        • Do not place the SST connector under the tire because it could be damaged.

      3. A004HM6

        Tie the tires together with the 2 wires.

        CAUTION:

        Make sure that the wires are tight. Looseness in the wires results in the tires breaking loose when the airbag is deployed.

    6. Deploy the airbag.


      1. Check that no one is within a 10 m (32.8 ft.) radius of the wheel to which the horn button assembly is tied.
