Traction Control Light Won’t Turn Off? (7 Fixes)

Having a well-functioning traction control system in your vehicle is crucial for maintaining stability and safety on the road. However, if you find that your traction control light won’t turn off, it can be frustrating and worrisome. In this article, we will explore seven potential fixes for this issue, providing you with solutions to get your traction control system back on track. Rest assured, with a few simple steps, you can address the problem and regain confidence in your vehicle’s performance.

1. Check the Wheel Speed Sensors

The wheel speed sensors play a vital role in the operation of the traction control system. If they become dirty or damaged, it can cause the traction control light to stay on. Inspect each wheel’s speed sensor and clean any debris or grime that may be obstructing its function. If the sensor is damaged, it may need to be replaced by a professional technician.

2. Inspect the Brake System

A faulty brake system can trigger the traction control light to illuminate. Check for any signs of brake wear or damage, such as worn brake pads or leaking brake fluid. If necessary, replace or repair the affected components. A properly functioning brake system is essential for the traction control system to operate correctly.

3. Verify Tire Conditions and Pressures

Inadequate tire conditions or incorrect tire pressures can cause the traction control light to remain on. Ensure that your tires have sufficient tread depth and are in good condition. Additionally, check and adjust the tire pressures to the recommended levels specified in your vehicle’s owner’s manual. Properly inflated and well-maintained tires contribute to optimal traction control performance.

4. Examine the ABS System

The Anti-lock Braking System (ABS) is closely related to the traction control system. A malfunctioning ABS can trigger the traction control light. Inspect the ABS system for any faults or damage. If you suspect an issue, it is advisable to consult a qualified mechanic who can diagnose and repair the ABS system as needed.

5. Battery and Electrical System Check

In some cases, a weak or failing battery or an electrical system glitch can cause the traction control light to persistently illuminate. Have your battery and electrical system inspected by a professional to ensure they are in proper working condition. If necessary, replace the battery or repair any electrical faults to resolve the issue.

6. Reset the Traction Control System

Resetting the traction control system can often resolve minor glitches or false alerts that cause the light to remain on. Refer to your vehicle’s owner’s manual for specific instructions on how to perform a system reset. This simple step can potentially clear any temporary issues and restore the normal functioning of the traction control system.

7. Consult a Professional Mechanic

If you have attempted the above fixes and the traction control light still won’t turn off, it is recommended to seek assistance from a professional mechanic. They have the expertise and specialized equipment to diagnose and address complex issues with the traction control system. A mechanic will be able to provide a thorough inspection and accurate diagnosis, ensuring that the underlying problem is properly resolved.

Frequently Asked Questions

Can I drive my vehicle with the traction control light on?

While it is generally safe to drive with the traction control light on, it is essential to address the underlying issue as soon as possible. The traction control system may be deactivated, which can affect the vehicle’s stability and handling in certain situations. Have the problem diagnosed and fixed to restore the full functionality of your vehicle’s safety systems.

Why did my traction control light turn on after replacing my tires?

After replacing tires, the traction control light may turn on due to differences in tire sizes, tread patterns, or inflation levels. This can confuse the traction control system, triggering the light. It is advisable to have the tire specifications and settings checked by a professional to ensure compatibility and proper functioning.

Can a faulty traction control system affect other vehicle systems?

The traction control system is interconnected with other vehicle systems, such as the ABS and stability control. A malfunctioning traction control system can potentially affect the operation and performance of these interconnected systems. Therefore, it is important to address any issues promptly to maintain optimal safety and vehicle functionality.


Experiencing a traction control light that won’t turn off can be concerning, but with the right approach, you can troubleshoot and resolve the issue. By checking the wheel speed sensors, inspecting the brake system, verifying tire conditions and pressures, examining the ABS system, ensuring a healthy battery and electrical system, performing a system reset, and seeking professional assistance if needed, you can address the problem and restore the proper functioning of your vehicle’s traction control system. Drive with confidence, knowing that you have taken the necessary steps to maintain stability and safety on the road.
