Steering Pad (For Sedan) -- Disposal

HINT:

When scrapping a vehicle equipped with the SRS or disposing of a steering pad, 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.

CAUTION:

Never dispose of a steering pad that has an undeployed airbag.
The airbag emits 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.

Disconnect the cable from the negative battery terminal.

Remove the steering pad (YARIS_NCP93 RM000000V6N028X.html).
CAUTION:
1. When removing the steering pad, work must be started at least 90 seconds after the power switch is turned off and the cable is disconnected from the negative battery terminal.
2. When storing the steering pad, keep the upper surface of the airbag deployment side facing upward.

Using a service-purpose wire harness for the vehicle, tie the steering pad to the disc wheel.
Stripped wire harness section:
Area
Measurement
A
1.25 mm² or more (0.0019 in.² or more)
CAUTION:
Do not use wire harness that is too thin or any other object to tie the steering pad because it may snap due to the shock when the airbag is deployed. Always use a wire harness for vehicle use with a cross section of at least 1.25 mm² (0.0019 in.²).
HINT:
To calculate the area of the stripped wire harness cross section:
Area = 3.14 x (Diameter)² divided by 4
1. Install the 2 bolts with washers into the 2 bolt holes in the steering pad.
  Bolt size:

  NOTICE:
  Do not lock the secondary lock of the twin lock to avoid damaging the SST connector and wire harness.
3. Using 3 wire harnesses, wind the wire harnesses at least 2 times each around the bolts installed on the left and right sides of the steering pad.
  CAUTION:
  1. Tightly wind the wire harnesses around the bolts so that there is no slack.
  2. Make sure that the wire harnesses are tight. If there is any slack in the wire harnesses, the steering pad may become loose due to the shock when the airbag is deployed.
4. Face the airbag deployment side of the steering pad upward. Using wire harnesses, separately tie the left and right sides of the steering pad to the disc wheel through the hub nut holes. Position the SST connector so that it hangs downward through the hub hole in the disc wheel.
  CAUTION:
  1. Make sure that the wire harnesses are tight. If there is any slack in the wire harnesses, the steering pad may become loose due to the shock when the airbag is deployed.
  2. Always tie the steering pad with the airbag deployment side facing upward. It is highly dangerous if the steering pad is tied with the airbag deployment side facing downward as the wire harnesses will be cut by the shock caused by the airbag deployment and the steering pad will be thrown into the air.
  NOTICE:
  The disc wheel will be marked by the airbag deployment, so use a waste disc wheel.
