Steering Pad: Disposal

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.
  1. PRECAUTION 

    HINT:

    When scrapping a vehicle equipped with an SRS or disposing of the steering pad, 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:
    • 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.
    • Never dispose of a steering pad 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 (33 ft.) away from the steering pad.
    • The steering pad 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 steering pad with a deployed airbag.
    • Do not apply water, etc. to a steering pad with a deployed airbag.
    • Always wash your hands with water after completing the operation.
  2. DISPOSE OF STEERING PAD (WHEN INSTALLED IN VEHICLE) 

    HINT:

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

    1. Check the function of SST.

      SST 09082-00700 

      CAUTION: When deploying the airbag, always use the specified SST:

    8. Deploy the airbag.
      1. Check that no one is inside the vehicle or within a 10 m (33 ft.) radius of the vehicle.
      2. Press the SST activation switch and deploy the airbag.
      CAUTION:
      • When deploying the airbag, make sure that no one is near the vehicle.
      • The steering pad 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 steering pad with a deployed airbag.
      • Do not apply water, etc. to a steering pad with a deployed airbag.
      • Always wash your hands with water after completing the operation.

      HINT:

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

  3. DISPOSE OF STEERING PAD (WHEN NOT INSTALLED IN VEHICLE) 
NOTE:
  • When disposing of the steering pad, never use the customer's vehicle to deploy the airbag.
  • Be sure to follow the following procedure when deploying the airbag.

HINT:

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

  1. Check the function of SST.

  2. Remove the steering pad (See REMOVAL ).
    CAUTION:
    • When removing the steering pad, before the work is started, leave the vehicle at least 90 seconds after turning the ignition switch off and disconnecting the cable from the negative (-) battery terminal.
    • When storing the steering pad, keep the airbag deployment side facing upward.
  3. Using braided wire, tie down the steering pad to an unneeded wheel.

    Wire: Stripped wire section 

    1.25 mm 2  (0.0019 in. 2  ) or more 

    CAUTION: If the wire is too thin or an alternative object is used to tie down the steering pad, it may be snapped by the shock 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 ).

    HINT:

    To calculate the area of the stripped wire section:

    Area = 3.14 x (Diameter)2 divided by 4

    1. Install the 2 bolts with washers into the 2 bolt holes on the steering pad.

      Bolt: 

      L: 35.0 mm (1.38 in.) 

      M: 6.0 mm (0.236 in.) 

      Pitch: 1.0 mm (0.0394 in.) 

      NOTE:
      • Tighten the bolts by hand until they become difficult to turn.
      • Do not tighten the bolts excessively.

      G06014833Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      CAUTION:
      • Tightly wind the wires around the bolts so that there is no slack.
      • Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose due to the shock when the airbag is deployed.
    4. Face the airbag deployment side of the steering pad upward on top of an unneeded tire and wheel set. Separately tie the left and right sides of the steering pad to the wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole of the wheel.
    CAUTION:
    • Make sure that the wires are tight. If there is slack in the wires, the steering pad may break loose due to the shock when the airbag is deployed.
    • Always tie down the steering pad with the airbag deployment side facing upward.

    NOTE: The wheel will be damaged by the airbag deployment, so use an unneeded wheel.
  4. Install SST.
    CAUTION: Place the wheel on level ground.
    1. Connect the SST connector.

      SST 09082-00700 

      NOTE: 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 disc wheel.

  5. Cover the steering pad (using a cardboard box).
    1. Cover the steering pad with the cardboard box.
    2. Place weights on the cardboard box in 4 places totalling at least 190 N (19 kg, 42.7 lb).

    Minimum cardboard box size: 

    Must exceed the following dimensions 

    X: 460 mm (18.1 in.) 

    Y: 650 mm (25.6 in.) 

    Fig 16: Covering Steering Pad
    G04979591Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    NOTE:
    • When dimension Y of the cardboard box exceeds the diameter of the wheel and tire which the steering pad is tied to, X should be the following size.

      X = 460 mm (18.1 in.) + width of tire

    • If a cardboard box which is smaller than the specified size is used, the cardboard box may be broken by the shock from the airbag deployment.
  6. Cover the steering pad (using tires).
    1. Place at least 3 tires without wheels onto the wheel and tire which the steering pad is tied to.
    2. Place the wheel and tire on top of them.

      Minimum tire size: Must exceed the following dimensions 

      Width: 185 mm (7.28 in.) 

      Inner diameter: 360 mm (14.2 in.) 

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

    3. 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 due to the shock when the airbag is deployed.
