• Q: How to replace the Clock Spring Assembly / Spiral Cable on 2005 Scion tC?

  A: Service requirements pertaining to Air Bag Systems must be observed before replacing either the Clock Spring Assembly / Clock Spring. The battery negative terminal must be disconnected for 90 seconds before continuing with the work process. The process starts with directive wheel alignment and subsequent horn button assembly and steering wheel assembly extraction using Special Service Tool: 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021). First detach both the lower steering column cover and clock spring sub-assembly by opening the upper steering column cover then unconnecting the connectors while safeguarding the Air Bag wire harness from damage. The clock spring sub-assembly must be taken out after disconnecting its three claws for examination of scratches or cracks or dents or chipping and requires replacement if you find these conditions. Installation of the new clock spring sub-assembly needs straight front wheels along with the turn signal switch in neutral position to prevent pin snapping incidents. Connect the clock spring sub-assembly with attention paid to the Air Bag connector. The lower steering column cover installation requires checking the ignition switch to be off and disconnecting the negative battery terminal before proceeding. Twist the clock spring sub-assembly downward until it feels secure, then continue turning it rightward two and a half turns at the marks while avoiding the Air Bag wire harness. Reinstall the steering wheel assembly before inspecting the steering wheel center point and returning the horn button assembly to its place. The final step includes reconnecting the battery negative terminal while performing a sequence of power window control and sliding roof system initialization before inspecting both the horn button assembly and SRS warning light.
