STEERING PAD DISPOSAL

Tech Tips

When scrapping vehicle equipped with an SRS or disposing of a horn button assembly (with airbag), always first deploy the airbag in accordance with the procedure described below. If any abnormality occurs with the airbag deployment, contact the SERVICE DEPT. of the DISTRIBUTOR.

CAUTION:

Never dispose of a horn button assembly which has an undeployed airbag.
The airbag produces a sizeable exploding sound when it deploys, so perform the operation out-of- doors 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 an airbag, perform the operation at least 10 m (33 ft) away from the horn button assembly.
The horn button assembly is very hot when the airbag is deployed, so leave it alone for at least 30 minutes after deployment.
Use gloves and safety glasses when handling a horn button assembly with the deployed airbag.
Always wash your hands with water after completing the operation.
Do not apply water, etc. to a horn button assembly with the deployed airbag.

DISPOSE OF HORN BUTTON ASSEMBLY (WHEN SCRAPPING VEHICLE DEPLOYMENT METHOD)

Tech Tips

Have a battery ready as the power source to deploy the airbag.

Check functioning of the SST.

CAUTION:

When deploying the airbag, always use the specified SST: SRS Airbag Deployment Tool.

  *1 Battery
  
  Connect the SST to the battery.
  
  Connect the red clip of the SST to the battery positive (+) terminal and the black clip to the battery negative (-) terminal.
  
  Tech Tips
  
  Do not connect the yellow connector which will be connected with the supplemental restraint system.
2. Check functioning of the SST.
  
  Press the SST activation switch, and check that the LED of the SST activation switch lights up.
  
  CAUTION:
  
  If the LED lights up when the activation switch is not being pressed, SST malfunction is probable, so definitely do not use the SST.
3. Disconnect the SST from the battery.

Install the SST.

CAUTION:

Check that there is no looseness in the steering wheel and horn button assembly.

Disconnect the airbag connector under the steering column tube LWR.
Connect the connectors of the 2 SST to the airbag connector of the spiral cable sub-assembly side.

*a	10 m (33 ft) or more

Move the SST at least 10 m (33 ft) away from the front of the vehicle.

Close all the doors and windows of the vehicle.

Note

Take care not to damage the SST wire harness.
Connect the red clip of the SST to the battery positive (+) terminal and the black clip to the negative (-) terminal.

Deploy the airbag.
1. Confirm that no one is inside the vehicle or within 10 m (33 ft) area around the vehicle.
2. Press the SST activation switch and deploy the airbag.
  
  Tech Tips
  
  The airbag deploys simultaneously as the LED of the SST activation switch lights up.
Dispose the horn button assembly (with airbag).
CAUTION:
- The horn button assembly is very hot when the airbag is deployed, so leave it alone for at least 30 minutes after deployment.
- When moving a vehicle for scrapping which has a horn button assembly with deployed airbag, use gloves and safety glasses.
- Use gloves and safety glasses when handling a horn button assembly with the deployed airbag.
- Always wash your hands with water after completing the operation.
- Do not apply water, etc. to a horn button assembly with the deployed airbag.
Tech Tips

When scrapping a vehicle, deploy the airbag and scrap the vehicle with the horn button assembly still installed.

DISPOSE OF HORN BUTTON ASSEMBLY (WHEN DISPOSING OF AIRBAG ASSEMBLY DEPLOYMENT METHOD)

Note

When disposing of the horn button assembly (with airbag) only, never use the customers vehicle to deploy the airbag.
Be sure to follow the procedure given below when deploying the airbag.

Tech Tips

Have a battery ready as the power source to deploy the airbag.

Remove the horn button assembly Click here.

CAUTION:

When storing the horn button assembly, keep the upper surface of the pad facing upward.

Using a service-purpose wire harness, tie down the horn button assembly to the disc wheel.

*a	Wire Harness Diameter
*b	Stripped Wire Harness Section

Wire harness
Stripped wire harness section 1.25 mm² or more (0.0019 in². or more)

CAUTION:

If a wire harness which is too thin or some other thing is used to tie down the horn button assembly, it may be snapped by the shock when the airbag is deployed. This is highly dangerous. Always use a wire harness for vehicle use which is at least 1.25 mm²(0.0019 in²).

Tech Tips

To calculate the square of the stripped wire harness section:

Square
Square = 3.14 x (Diameter)² divided by 4

Install the 2 bolts with washers in the 2 bolt holes in the horn button assembly.

Bolt
L: 35.0 mm (1.387 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)

Note

Tighten the bolts by hand until the bolts become difficult to turn.
Do not tighten the bolts too much.

*a 2 Times or more

Using 3 wire harness, wind the wire harness at least 2 times each around the bolts installed on the left and right sides of the horn button assembly.
CAUTION:
- Tightly wind the wire harness around the bolts so that there is no slack.
- If there is slack in the wire harness, the horn button assembly may come loose due to the shock when the airbag is deployed. This is highly dangerous.

*2	Disc Wheel

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

CAUTION:

Make sure that the wire harness is tight. It is very dangerous when looseness in the wire harness results in the horn button assembly coming free through the shock from the airbag deploying.
Always tie down the horn button assembly with the pad side facing upward. It is very dangerous if the horn button assembly is tied down with the metal surface facing upward as the wire harness will be cut by the shock from the airbag deploying and the horn button assembly will be thrown into the air.

Note

The disc wheel will be marked by airbag deployment, so when disposing of the airbag use a redundant disc wheel.

Cover the horn button assembly with a cardboard box or tires.

Covering method using a cardboard box:

Cover the horn button assembly with the cardboard box and weight the cardboard box down in 4 places with at least 190 N (20 kg, 44 lb).

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

Note

When dimension Y of the cardboard box exceeds the diameter of the disc wheel with tire to which the horn button assembly is tied, X should be the following size. X = 460 mm (18.11 in.) + width of tire
If a cardboard box smaller than the specified size is used, the cardboard box will be broken by the shock from the airbag deployment.

Covering method using tires:

Place at least 3 tires without disc wheel on top of the disc wheel with tire to which the horn button assembly is tied.

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.

Note

The tires may be marked by the airbag deployment, so use the redundant tires.
