What Is a Clock Spring?
A clock spring, also known as a coil spring unit, spiral cable, or cable reel assembly, is an essential device in a car that connects the steering wheel to various electrical components. Its purpose is to allow the smooth rotation of the steering wheel without damaging the cables connected to it. The clock spring is located between the steering wheel and the steering column, ensuring the safe and efficient functioning of systems like cruise control, airbag deployment, and horn operation.
In simple terms, the clock spring acts as a connector between the steering wheel and the car’s electrical systems. It consists of a coiled wire that can rotate as the steering wheel turns. This rotation allows the various buttons on the steering wheel to connect to the vehicle’s systems, such as controlling the cruise control or activating the horn. Without a properly functioning clock spring, these essential functions would not work as intended.
The location of the clock spring between the steering wheel and steering column is crucial for its functioning. It is usually part of the same assembly as the turn signal lever, making it easily accessible. However, accessing the clock spring requires the removal of the steering wheel and the covers covering the steering wheel axle. This ensures that the clock spring is properly secured and can transmit the necessary signals from the steering wheel to the car’s electrical systems.

How Does a Clock Spring Work?
A clock spring functions by using connectors to link the steering wheel buttons to various systems in a car. These connectors allow for the transmission of power through conductors inside the spring, enabling the buttons to control functions such as cruise control and radio volume. The clock spring also facilitates the rotation of the steering wheel without damaging the cables connected to it.
When the steering wheel is turned, the clock spring rotates along with it. This rotation allows the conductors inside the spring to maintain a continuous electrical connection while the steering wheel moves. If the conductors break, the clock spring will no longer be able to transmit power, resulting in the malfunctioning of the steering wheel buttons.
In summary, the clock spring’s connectors and rotation mechanism are essential for the transmission of power and the proper functioning of the steering wheel buttons in a car.
Key Points:
- The clock spring has connectors that link the steering wheel buttons to various systems in a car.
- When the steering wheel is turned, the clock spring rotates, maintaining a continuous electrical connection.
- If the conductors inside the clock spring break, the steering wheel buttons will malfunction.
Clock Spring Purpose
The clock spring serves several important purposes in a car.

How Do You Test a Clock Spring’s Functionality?
Testing the functionality of a clock spring is essential to ensure the smooth operation of various electrical components in a car. One way to test a clock spring is by using a multimeter. Here’s a step-by-step guide on how to perform the test:
- Set the multimeter to the Ohms setting.
- Connect the positive lead of the multimeter to the clock spring plug that connects to the airbag system.
- Connect the negative lead to one of the power supply pins in the backside port of the clock spring.
- Rotate the clock spring to simulate the movement of the steering wheel.
- Observe the readings on the multimeter. Inconsistent or infinite readings indicate a faulty clock spring.
By following this procedure, you can determine whether the clock spring is functioning properly or if it needs to be replaced. It is important to note that clock springs cannot be repaired and should be replaced if they are found to be faulty.
Table: Clock Spring Functionality Test Results
| Rotation | Multimeter Reading | Interpretation |
|---|---|---|
| Clockwise | 5 ohms | Normal |
| Counterclockwise | 10 ohms | Normal |
| Full Rotation | Infinite | Faulty Clock Spring |
As seen in the table above, a properly functioning clock spring should display consistent resistance readings in both clockwise and counterclockwise rotations. A reading of “infinite” indicates a faulty clock spring that needs to be replaced. It is recommended to consult a professional mechanic for accurate testing and replacement of a clock spring if necessary.
What Does the Clock Spring Do with an Airbag?
The clock spring plays a critical role in the deployment of the airbag. It is responsible for transmitting signals from the steering wheel to the car’s computer, which triggers the deployment of the airbag when necessary. When a collision or impact is detected, the car’s computer sends a signal to the clock spring, which then activates the airbag system.
The clock spring ensures that the necessary electrical connections between the steering wheel and the airbag system are maintained during steering wheel rotation. It allows the airbag to deploy effectively, protecting the driver and passengers in the event of an accident. Without a properly functioning clock spring, the airbag may not deploy correctly or may not deploy at all, posing a significant safety risk.
Understanding the Clock Spring-Airbag Connection
The clock spring is connected to the airbag system through electrical wiring, which enables the communication between the steering wheel and the car’s computer. It allows the steering wheel to rotate freely while maintaining the integrity of the electrical connections. Any disruption or damage to the clock spring can result in a loss of communication between the steering wheel and the airbag system, potentially compromising the effectiveness of the airbag deployment.
Regular maintenance and prompt replacement of a faulty clock spring are crucial for ensuring the safe operation of the airbag system. If any symptoms of a broken clock spring arise, such as a malfunctioning horn or airbag warning light, it is essential to have the clock spring inspected and replaced by a qualified professional.
| Common Clock Spring-Airbag Connection Issues: | Effects on Airbag Deployment: |
|---|---|
| Broken clock spring | Airbag may not deploy or may deploy incorrectly |
