TOYOTA 84306-60090 Spiral Cable Sub-Assembly

The genuine Toyota spiral cable sub-assembly with part number 84306-60090 (also known as an airbag clock spring) is a precision electromechanical component responsible for maintaining a continuous electrical connection between the steering wheel and the stationary steering column. It plays a vital role in the vehicle's passive safety system by ensuring a constant connection between the driver-side supplemental restraint system (SRS) airbag and the control module, while reliably transmitting electrical signals to the horn and steering wheel-integrated control switches.

Operation and Technical Significance: The flexible ribbon cable coiled inside the housing winds or unwinds as the steering wheel is turned in either direction, preventing the internal conductive ribbons from kinking or experiencing mechanical stress. Wear or fatigue failure of the internal ribbon is most commonly indicated by an illuminated SRS airbag warning light on the instrument cluster, failure of the horn, or clicking and rubbing noises when turning the steering wheel. In the event of a malfunction, the driver's airbag will not deploy during an impact, making the prompt replacement of a damaged component safety-critical.
