Essential Steering Component: Spiral Cable Sub-Assembly

The Spiral Cable Sub-Assembly, often referred to as the clock spring, is a crucial component within the steering system of modern vehicles. It ensures proper electrical connection between the steering wheel and the vehicle's electronic systems, allowing for the seamless operation of features like airbags, horn, and steering wheel controls.

Functionality Explained

This part comprises a flat ribbon of conductive material wound in a spiral shape, creating the necessary slack to enable the steering wheel to turn freely while maintaining an uninterrupted electrical connection. As you rotate the steering wheel, the spiral cable winds and unwinds, effectively managing the circuit continuity.

Consequences of Malfunction

If the Spiral Cable Sub-Assembly becomes damaged or broken, several critical functions could be compromised. The airbag system may become inoperable, posing a significant safety risk. Additionally, electronic features such as audio controls and the horn may cease to function, affecting comfort and convenience.
