Everything You Need to Know About the Airbag Clockspring

What Is an Airbag Clockspring?

An airbag clockspring (also spelled clock spring) is a crucial component in a vehicle’s steering column. It maintains the electrical connection between the steering wheel-mounted controls, such as the airbag, horn, cruise control, and audio buttons, and the vehicle’s wiring harness while allowing the steering wheel to turn.

How Does a Clockspring Work?

The clockspring consists of a coiled ribbon cable inside a plastic housing. As the driver turns the steering wheel, the ribbon cable winds and unwinds, ensuring continuous electrical contact without breaking the circuit. This design allows drivers to control various systems in the vehicle while maintaining a full range of steering motion.

If the clockspring fails, it can lead to issues such as a non-functioning airbag, inoperative horn, or unresponsive steering wheel buttons.

Types of Clocksprings and Their Use Cases

There are different types of clocksprings used in modern vehicles, including:

1. Standard Clocksprings

  • Found in most vehicles with basic airbag and steering wheel control functions.
  • Ensures uninterrupted connection for airbags and essential electrical components.

2. Multi-Function Clocksprings

  • Used in vehicles with advanced steering wheel functions, such as heated steering, paddle shifters, and integrated infotainment controls.
  • More complex in design and requires precise alignment during installation.

3. Adaptive Clocksprings

  • Found in vehicles with ADAS (Advanced Driver Assistance Systems).
  • Works with steering angle sensors and electronic stability control systems.

Common Causes of Clockspring Failure

A faulty clockspring can compromise vehicle safety and functionality. The most common causes of failure include:

  • Normal wear and tear – Repeated turning of the steering wheel over time can wear out the ribbon cable.
  • Accident-related damage – If the airbag deploys, the clockspring often gets damaged and needs replacement.
  • Improper installation – Misalignment during steering column repairs can cause premature failure.
  • Electrical short circuits – Moisture or internal faults can lead to electrical failures.

How Long Does a Clockspring Last?

The lifespan of a clockspring varies based on driving habits and vehicle use. On average, it lasts 100,000 to 150,000 miles. However, it should be inspected whenever electrical issues arise in the steering wheel.

Signs You Need to Replace a Clockspring

If the airbag clock spring is failing, you may notice:

  • Airbag warning light on the dashboard.
  • Non-functional horn or steering wheel buttons.
  • Clicking noise when turning the steering wheel.
  • Cruise control not working.
  • Airbag deployment failure in case of an accident.

Ignoring a bad clockspring can compromise safety, so it’s best to replace it immediately.

DIY Guide: How to Replace an Airbag Clockspring

Replacing a clockspring requires precision to avoid airbag system errors. Follow these steps for a successful DIY installation.

Tools & Supplies Needed:

  • New airbag clockspring (OEM or high-quality aftermarket replacement)
  • Socket set and ratchet
  • Steering wheel puller (if needed)
  • Torx and Phillips screwdrivers
  • Electrical cleaner (optional)
  • Thread locker (if required)
  • Protective gloves and safety glasses

Step-by-Step Instructions:

Step 1: Disconnect the Battery

  • Turn off the engine and disconnect the negative battery terminal.
  • Wait 10-15 minutes to prevent accidental airbag deployment.

Step 2: Remove the Steering Wheel Airbag

  • Locate the airbag retaining screws on the back of the steering wheel.
  • Carefully detach the airbag and disconnect the airbag wiring harness.

Step 3: Remove the Steering Wheel

  • Mark the steering wheel’s alignment to ensure proper reinstallation.
  • Use a steering wheel puller to safely remove the wheel.

Step 4: Remove the Old Clockspring

  • Unscrew the plastic column covers and locate the clockspring assembly.
  • Disconnect the wiring connectors and remove the faulty clockspring.

Step 5: Install the New Clockspring

  • Ensure the new clockspring is centered (many have a locking pin for this purpose).
  • Reconnect all wiring harnesses properly.

Step 6: Reassemble the Steering Column

  • Reinstall the steering wheel, ensuring alignment marks match.
  • Secure the airbag module and reconnect all components.

Step 7: Reconnect the Battery and Test

  • Reconnect the battery and start the vehicle.
  • Check that the horn, buttons, and airbag system function correctly.
  • If the airbag warning light stays on, a scan tool may be required to reset the system.

Additional Parts & Consumables Needed

  • Steering wheel puller (if necessary for your vehicle)
  • Dielectric grease (for electrical contacts)
  • OEM airbag screws (if damaged or missing)
  • Steering angle sensor reset tool (for some modern vehicles)

Final Thoughts

The airbag clockspring is a small yet essential part of a vehicle’s safety system. A failing clockspring can disable the airbag system, horn, and steering wheel controls, making timely replacement crucial.

While a front clockspring replacement is a manageable DIY task, it requires care to avoid airbag-related issues. If you’re unsure, seeking professional help is always a good option.

If you suspect a clockspring failure, don’t ignore it—inspect and replace it promptly to maintain your vehicle’s safety and functionality.
