An Airbag Clockspring is an assembly that contains a spirally wound flat ribbon to allow the steering wheel to be turned while maintaining a constant electrical connection to the driver airbag, horn and other electrical steering wheel mounted controls.
The spiral cable is simply a coil of wires in a doughnut shaped container that connects the airbag to the car's electronics and after about 100,000 km of driving, it sustains a crack in the wiring within it
