Key Functions
The clock spring maintains continuous electrical connection between the steering wheel and vehicle systems, enabling:

  • ✅ Airbag (SRS) system – critical safety component
  • ✅ Horn operation
  • ✅ Radio volume and station controls
  • ✅ Cruise control switches

Signs of Failure
A faulty clock spring may exhibit the following symptoms:

  • ⚠️ Airbag warning light illuminates on dashboard
  • 📢 Horn does not function
  • 🎛️ Steering wheel-mounted controls become unresponsive
  • 🚨 In critical cases, driver airbag may not deploy in a collision

⚠️ IMPORTANT SAFETY NOTE & INSTALLATION TIPS

Before Installation: Disconnect the battery negative terminal and wait at least 5 minutes for the airbag system to discharge.

Centering: Ensure front wheels are perfectly straight. The new clock spring comes with a centering clip – do NOT remove this clip until the clock spring is fully installed and the steering wheel is in position. Rotating the clock spring without the clip can damage the internal ribbon cable.

Verification: Always verify that the replacement part matches your original in connector type and pin configuration. To confirm compatibility, email your vehicle's 17-digit VIN number.

Post-Installation: After installation, verify horn function, radio controls, cruise control, and ensure the airbag warning light extinguishes correctly.

Safety Note: Since the clock spring is responsible for two safety devices (horn and airbag system), it is highly advised to replace a faulty unit as soon as possible. Professional installation recommended.
