Traction control is a crucial safety function that aids in maintaining stability and control for drivers on slick surfaces.
As a result, to regain traction, the traction control system will apply the brakes to particular wheels and restrict engine power.
The traction control light, which is a warning light that illuminates the dashboard, can serve as an indicator of this.
The traction control light can raise some red flags though if it doesn’t go out. In this post, we’ll look at several typical causes of the traction control light staying on and discuss possible solutions.

What is Traction Control Light?
The traction control light is an alert that flashes when there is an issue with the traction control system.
The technology is intended to assist drivers in keeping traction and stability, particularly in challenging driving conditions like rain, snow, or ice. A yellow or orange warning light is often shown on the dashboard.
Reasons Why Your Traction Control Light Won’t Turn Off
1. ABS (Anti-lock Braking System) Problems
This problem can cause the traction control light to turn on and stay on. This is because the ABS and the traction control system are closely related. Therefore, a problem with the ABS can affect the traction control system.
Various issues can cause Anti-lock Braking problems, such as a failing ABS control module, damaged sensors, or wiring issues.
2. Low Tire Pressure
This can also cause the traction control light to turn on and stay on. Low tire pressure can affect the traction control system and cause it to perform poorly.
The traction control system uses information from the ABS sensors and the wheels to determine how much traction the tires have, and low tire pressure can result in incorrect readings.
3. Issues with the Suspension or Wheels
This warning light might also come on and stay on due to issues with the wheels or suspension. This is because the performance of the traction control system is greatly influenced by the wheels and suspension.
In other words, the control system may experience problems, resulting in the light turning on, due to faults such as bent wheels, worn suspension parts, or damaged wheel bearings.
4. Difficulty with the Throttle Control System
The traction control indicator may also illuminate and remain illuminated due to issues with the throttle control system.
This is so that the vehicle can retain stability and traction with the aid of the traction control and throttle systems working in tandem.
Furthermore, indicators may illuminate due to difficulties with the traction control system, such as a failed throttle position sensor, a filthy throttle body, or an out-of-adjustment throttle cable.
5. Issues with the Traction Control System
This condition can cause the light to turn on and stay on. Various issues, such as a failing traction control module, damaged traction control sensors, or traction control wiring issues, can cause this.
If the problem is with the traction control system itself, it’s important to have it repaired as soon as possible to ensure the safety of your vehicle.
6. Faulty Wheel Speed Sensor
The wheel speed sensor is responsible for monitoring the speed of each wheel. If the wheel speed sensor damages or fails, the traction control system will not be able to accurately detect a loss of traction, causing the traction control light to stay on.
How to Fix a Traction Control Light that Won’t Turn Off
1. Check Tire Pressure
The first step in fixing a traction control light that won’t turn off is to check the tire pressure. Incorrect tire pressure can affect the traction control system and cause the light to come on. Check the tire pressure and fill the tires to the recommended level as specified in your vehicle’s owner’s manual.
2. Check Wheels and Suspension
If the tire pressure is within the recommended range, it is time to check the wheels and suspension for any visible damage or wear.
A damaged wheel or suspension component can affect the traction control system, causing the light to come on. Inspect the wheels and suspension thoroughly, and replace any damaged components if necessary.
3. Reset the Traction Control System
When you have verified there are no issues with the tire pressure, wheels, and suspension, you can reset the traction control system by disconnecting the battery for a few minutes. After reconnecting the battery, start the vehicle and check if the traction control light is still illuminated.
4. Drive the Vehicle
You need to move the vehicle to see if the light comes back on. If it does, the problem may be related to the ABS. In this case, proceed to the next step.
5. Check and Replace the ABS System Control Module
The ABS control module can cause the traction control light to come on if it is damaged or does not work properly. Have a professional diagnose the ABS control module and replace it if necessary.
6. TCS Needs To Be Reprogrammed
In some cases, the traction control system may need to be reprogrammed by a professional mechanic. If the previous steps have not resolved the issue with the traction control light, it is recommended to have a professional diagnose and reprogram the system if necessary.
7. Contact a Professional Mechanic
If the steps listed above do not resolve the issue with the traction control light, it’s best to take your vehicle to a professional mechanic for a diagnostic test.
The mechanic will be able to identify the root cause of the problem and provide a solution. It’s also important to take your vehicle to a professional if you notice any other warning lights on the dashboard, as this could indicate a more serious issue with the vehicle.
FAQs on Traction Control Light That Won’t Turn Off
Can I Still Drive With Traction Control Light On?
Yes, you can still drive with the traction control light on, but it is recommended to address the problem as soon as possible to maintain the safety and performance of your vehicle.
The traction control light indicates potential issues with the traction control system, and ignoring it can result in further damage to the system or other components of your vehicle.
Diagnosing and fixing the problem as soon as possible is recommended to avoid any safety risks or potential for increased repair costs in the future.
Where is the Traction Control Sensor Located?
The traction control sensor is typically located on the wheel hub or near the abs sensor. The exact location can vary based on the make and model of your vehicle.
It is responsible for monitoring the speed of each wheel and sending signals to the traction control system to adjust engine power and apply the brakes to individual wheels as needed to maintain traction.
If you are still determining the location of the traction control sensor, it is recommended to consult your vehicle owner’s manual or a professional mechanic for assistance.
