RS–11 SUPPLEMENTAL RESTRAINT SYSTEM – STEERING WHEEL PAD AND SPIRAL CABLE IF THE AIRBAG IS DEPLOYED (a) Do a diagnostic system check. (See page RS–44) (b) Do a visual check which includes the following items with the steering wheel pad (with airbag) removed from the vehicle. • Check for deformation of the horn button contact plate of the steering wheel. • Check for damage to the spiral cable connector and wire harness. HINT: • If the horn button contact plate of 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 the steering wheel, and the clearance should be uniform all the way around when the new steering wheel pad is installed on the steering wheel. REPLACEMENT REQUIREMENTS In the following cases, replace the steering wheel pad, steer- ing wheel or spiral cable. • If the airbag has been deployed. • If the steering wheel pad or spiral cable has been found to be faulty in troubleshooting. • If the steering wheel pad, steering wheel or spiral cable has been found to be faulty during the check in items 1–(b) or 2–(b). • If the steering wheel pad has been dropped. CAUTION: For replacement of the steering wheel pad, see page RS–12, "STEERING WHEEL PAD AND SPIRAL CABLE REMOVAL AND INSTALLATION" and be sure to follow the correct procedure.
