Driver Side Knee Airbag Assembly: Disposal

HINT:

When scrapping a vehicle equipped with an SRS or disposing of the driver side knee 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 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 your bare hands to discharge static electricity before performing this procedure.
  • Never dispose of a driver side knee airbag 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 (33 ft.) away from the driver side knee airbag assembly.
  • The driver side knee 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 driver side knee airbag assembly with a deployed airbag.
  • Do not apply water, etc. to a driver side knee airbag assembly with a deployed airbag.
  • Always wash your hands with water after completing the operation.
  1. DISPOSE OF DRIVER SIDE KNEE AIRBAG ASSEMBLY (WHEN INSTALLED IN VEHICLE) 

    HINT:

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

    1. Check the function of SST (See DISPOSAL  ).

    2. Refer to PRECAUTION  .
    3. Disconnect the cable from the negative battery terminal.
      CAUTION: Wait for at least 90 seconds after disconnecting the cable to prevent airbag deployment.
    4. Disconnect the driver side knee airbag connector.
      NOTE: Take care not to damage the airbag wire harness.
    5. Install SST.
      1. Connect the SST connector to the driver side knee airbag assembly.

        SST 09082-00700, 09082-00770 

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

      3. Maintaining sufficient clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.
        NOTE: Take care not to damage the SST wire harness.
      4. Connect the red clip of SST to the battery positive (+) terminal and the black clip of SST to the battery negative (-) terminal.
    6. 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 driver side knee 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 driver side knee airbag assembly with a deployed airbag.
        • Do not apply water, etc. to a driver side knee 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 the SST activation switch comes on.

  2. DISPOSE OF DRIVER SIDE KNEE AIRBAG ASSEMBLY (WHEN NOT INSTALLED IN VEHICLE) 
    NOTE:
    • When disposing of the driver side knee airbag assembly, never use the customer's vehicle to deploy the airbag.
    • Be sure to follow the procedure detailed below when deploying the airbag.

    HINT:

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

    1. Check the function of SST (See DISPOSAL  ).
    2. Remove the driver side knee airbag assembly (See REMOVAL  ).
      CAUTION:
      • When removing the driver side knee airbag assembly, work must be started at least 90 seconds after the ignition switch is turned off and the negative (-) terminal cable is disconnected from the battery.
      • When storing the driver side knee airbag assembly, keep the airbag deployment side facing upward.

    3. Using braided wire, tie down the driver side knee airbag assembly to an needed tire.

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

      CAUTION: If the wire harness is too thin or an alternative object is used to tie down the driver side knee airbag assembly, 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. Position the driver side knee airbag assembly inside the tire with the airbag deployment side facing inside.

        Minimum tire size: Must exceed the following dimensions 

        Width: 185 mm (7.28 in.) 

        Inner diameter: 360 mm (14.17 in.) 

        CAUTION:
        • Make sure that the wires are tight. If there is slack in the wires, the driver side knee airbag assembly may break loose due to the shock when the airbag is deployed.
        • Always tie down the driver side knee airbag assembly with the airbag deployment side facing inside the tire as shown below.
        NOTE: The tire will be marked by the airbag deployment, so use an unneeded tire.

    5. Place the tires.
      1. Place at least 2 tires under the tire which the driver side knee airbag assembly is tied to.
      2. Place at least 2 tires over the tire which the driver side knee airbag assembly is tied to. The top tire should have a wheel installed.
        NOTE: 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.

        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.

    8. Dispose of the driver side knee airbag assembly.
      CAUTION:
      • The driver side knee 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 driver side knee airbag assembly with a deployed airbag.
