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.

Tech Tips


  • Use the same procedure for RHD and LHD vehicles.

  • The procedures listed below are for LHD vehicles.

PROCEDURE


  1. PRECAUTION

    CAUTION:


    • Do not perform this procedure indoors or on rough roads where safety cannot be ensured. Also, do not deploy SRS parts near residential areas.

    • If this procedure is performed indoors or on rough roads where safety cannot be ensured, unforeseen injuries may occur. Also, the deployment noise creates a nuisance to nearby residents.

      B0024VO

    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 Installed in Vehicle)

    Note


    • When disposing of the horn button assembly, use an unneeded vehicle to deploy the airbag.

    • 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. B0024CLN26

      Check the function of SST.

      SST
      09082-00700

      CAUTION:


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

        SRS Airbag Deployment Tool

      • B0026BF

        If the procedure is performed using unspecified SST, the airbag may deploy in an unforeseen situation and cause a serious accident.


      1. B0025JNN03

        Connect SST to the battery.

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

      2. B0025SDN10

        Check the function of SST.

        Press the SST activation switch and check that the LED of the SST activation switch comes on.

        CAUTION:


        • Do not connect the SST connector to the airbag before inspecting SST.

        • If the airbag deploys due to malfunction of SST, it may cause a serious accident.

        • If the LED comes on when the activation switch is not being pressed, SST is malfunctioning. Replace SST.

      3. Disconnect SST from the battery.

    2. Refer to Precaution.

        Connect the SST connector to the airbag connector of the spiral with cable sensor sub-assembly.

        SST
        09082-00700

        CAUTION:


        • B0026O5

          Do not deploy if the steering wheel assembly and horn button assembly are loose.

        • If deployed while the steering wheel assembly and horn button assembly are loose, the steering wheel assembly and horn button assembly may fly off and cause serious injuries.

        Note

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

      2. B0024NVC02
        *a 10 m or more

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

      3. While maintaining sufficient clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.

        CAUTION:


        • Do not deploy with all the doors and door windows open.

        • If deployed with all the doors and door windows open, dust and gas may enter the eyes or be breathed in.

        B00262C

        Note

        Take care not to damage the SST wire harness.

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

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

        CAUTION:


        • Do not deploy with people inside or around the vehicle.

        • If deployed with people inside or around the vehicle, serious injuries may occur.

        B00273W

        Tech Tips

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

    8. Remove the horn button assembly.

      Click here

      CAUTION:


      • B0026A4

        The horn button assembly becomes extremely hot when the airbag is deployed, so do not touch it for at least 30 minutes after deployment.

      • If not left alone for 30 minutes or more, burns may occur when touched.

      • B0028DA

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

      • If water is applied to the horn button assembly immediately after deployment, burns may occur from the resulting steam.

      • B0024QN

        Always wear safety glasses and gloves when handling a deployed horn button assembly.

      • If the horn button assembly is touched without wearing safety glasses and gloves, hot parts may cause burns and dust may enter the eyes.

      • After removal, quickly seal the horn button assembly in a plastic bag.

    9. Dispose of the horn button assembly.


      1. Place the horn button assembly in a plastic bag, tie it tightly and dispose of it according to local regulations.

        CAUTION:

        • B0025QF

          Always wear safety glasses and gloves when handling a deployed horn button assembly.

        • If the horn button assembly is touched without wearing safety glasses and gloves, hot parts may cause burns and dust may enter the eyes.

        • B0026Q3

          Never dispose of a horn button assembly with an undeployed airbag.

        • If an undeployed horn button assembly is disposed of, and then deploys for any reason, unforeseen injuries may occur.

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