CAUTION:

Disposal


1. DISPOSE OF HORN BUTTON ASSY (WHEN INSTALLED IN VEHICLE)

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

DISPOSE OF HORN BUTTON ASSY (WHEN INSTALLED IN VEHICLE)


(a) Check the function of the SST.

  1. Check the function of the SST.

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

    CAUTION: If the LED comes on when the activation switch is not being pressed, SST malfunction is possible, so be sure not to use the SST.

  2.  Disconnect the SST from the battery.

(b) Precaution (see page 60-1 ).

(c) Disconnect the battery negative terminal (see page 60-1 ).

DISPOSE OF HORN BUTTON ASSY (WHEN INSTALLED IN VEHICLE)


(d) Remove the steering column cover LWR.

  1.  While turning the steering wheel assy to the right and left, remove the 3 screws and steering column cover LWR.

DISPOSE OF HORN BUTTON ASSY (WHEN INSTALLED IN VEHICLE)


(e) Install the SST.

CAUTION: Check that there is no looseness in the steering wheel assy and horn button assy.

  1.  Disconnect the airbag connector (yellow colored one) from the spiral cable sub-assy.

    NOTICE: When handling the airbag connector, take care not to damage the airbag wire harness.

  2.  Connect the SST connector to the airbag connector of the spiral cable sub-assy.

SST 09082-00700, 09082-00780

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

DISPOSE OF HORN BUTTON ASSY (WHEN INSTALLED IN VEHICLE)


  1. Move the SST at least 10 m (33 ft) away from the vehicle front side window.
  2. Maintaining enough clearance for the SST wire harness in the front side window, close all doors and windows of the vehicle.

    NOTICE: Take care not to damage the SST wire harness.

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

(f) 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:

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

2. DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)

NOTICE:

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

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


(a) Check the function of the SST (see step 1-(a)).

(b) Remove the horn button assy (see page 60-17 ).

CAUTION:

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


(c) Using a service-purpose wire harness for the vehicle, tie down the horn button assy to the disc wheel.

Wire harness: Stripped wire harness section 1.25 mm2 or more (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 assy, it may be snapped by the shock when the airbag is deployed. This is highly dangerous. Always use a wire harness 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 harness section: Area = 3.14 x (Diameter)2 divided by 4

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1.  Install the 2 bolts with washers into the 2 bolt holes on the horn button assy.

Bolt: L: 35.0 mm (1.378 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)

NOTICE:

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1. After connecting the SST below to each other, connect them to the horn button assy.

SST 09082-00802 (09082-10801, 09082-30801)

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1. Using 3 wire harnesses, wind wire harness at least 2 times each around the bolts installed on the left and right sides of the horn button assy.

CAUTION:

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1. Face the upper surface of the horn button assy upward.

    Separately tie the left and right sides of the horn button assy to the disc wheel through the hub nut holes. Position the SST connector so that it hangs downward through a hub hole in the disc wheel.

CAUTION: Make sure that the wire harness is tight. If there is slack in wire harness, the horn button assy may become loose due to the shock when the airbag is deployed. This is highly dangerous.

Always tie down the horn button assy with the pad side facing upward. It is highly dangerous if the horn button assy is tied down with the metal surface facing upward as the wire harness will be cut by the shock caused by the airbag deployment and the horn button assy will be thrown into the air.

NOTICE: The disc wheel will be marked by the airbag deployment, so use an extra disc wheel.

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


(d) Install the SST.

CAUTION: Place the disc wheel on level ground.

  1.  Connect the SST connector.

SST 09082-00700

NOTICE: 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.

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1. Move the SST at least 10 m (33 ft) away from the horn button assy tied down to the disc wheel.

(e) Cover the horn button assy with a cardboard box or tires.

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1.  Covering method using a cardboard box: Cover the horn button assy with the cardboard box and place the weights on the cardboard box in 4 places with at least 190 N (19 kg, 43 lb).

Size of cardboard box: Must exceed the following dimensions: X = 460 mm (18.11 in.) Y = 650 mm (25.59 in.)

NOTICE:

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1. Covering method using tires: Place at least 3 tires without disc wheels on top of the tire with disc wheel which the horn button assy is tied to.

Tire size: Must exceed the following dimensions

Width: 185 mm (7.28 in.)

Inner diameter: 360 mm (14.17 in.)

CAUTION: Do not use tires with disc wheels.

NOTICE:

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


  1.  Tie the tires together with 2 wire harnesses.

CAUTION: Make sure that the wire harness is tight. It is highly dangerous when looseness in the wire harness results in the tires coming free due to the shock when the airbag is deployed.

DISPOSE OF HORN BUTTON ASSY (WHEN NOT INSTALLED IN VEHICLE)


(f) Deploy the airbag.

  1.  Connect the red clip of the SST to the battery positive (+) terminal and the black clip of the SST to the battery negative (-) terminal.
  2.  Check that no one is within a 10 m (33 ft) radius of the disc wheel which the horn button assy is tied to.
  3.  Press the SST activation switch and deploy the airbag.

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.
