A clock spring (also known as a spiral cable or spiral clock spring) is a crucial electrical component located inside the steering wheel assembly of a vehicle. It maintains the electrical connection between the steering wheel and the vehicle’s electrical systems while allowing the steering wheel to rotate freely.
Key Functions:
Transfers power and signals to steering wheel controls like the horn, airbag, audio switches, and cruise control.
Maintains uninterrupted electrical connection while the wheel turns.
Ensures proper airbag deployment during a collision.
Signs of a Faulty Clock Spring:
Airbag warning light illuminated.
Horn or steering wheel controls not working.
Noise or resistance when turning the steering wheel.
Recommendation:
Replace the clock spring immediately if damaged to maintain safety features such as airbag operation and steering wheel control functions.
