Air Bag Systems

Repairs and Inspections Required After A Collision


Steering Wheel Pad and Spiral Cable




1. VEHICLES NOT INVOLVED IN COLLISION
a. Do a diagnostic system check.
b. Do a visual check which includes the following items with the steering wheel pad (with airbag) installed in the vehicle.
Check cuts, minute cracks or marked discoloration on the steering wheel pad top surface and in the grooved portion.




2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS NOT DEPLOYED
a. Do a diagnostic system check.
b. Do a visual check which includes the following items with the steering wheel pad (with airbag) removed from the vehicle.
- Check cuts, minute cracks or marked discoloration on the steering wheel pad top surface and in the grooved portion.
- Check cuts and cracks in wire harnesses, and chipping in connectors.
- Check the deformation of the horn button contact plate of the steering wheel.
- Check the deformation on the steering wheel.




HINT:
- If the horn button contact plate on the steering wheel is deformed, never repair it. Always replace the steering wheel assembly with a new one.




- There should be no interference between the steering wheel pad and steering wheel, and the clearance should be uniform all the way around when the new steering wheel pad is installed on the steering wheel.

CAUTION: Be sure to follow the correct procedure for removal and installation of the steering wheel pad.

3. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS DEPLOYED
