A traction control light informs you when the system is running; it is engaged if the light flashes on and off while you are driving. A dashboard warning light that indicates traction control is disabled, and, in some cases, ABS is also disabled. It will typically illuminate when there is a problem with the system.
The common reasons why your traction control light stays on are either the TSC system is turned off, the wheel speed sensor malfunctions, the steering angle sensor is bad, the wiring is damaged, or the ABS malfunctions.
Everything is working as it should if your wheels are slipping and the light is on. In addition, when you first turn the key in the ignition, the light ought to come on and then go off. As long as the light goes out, there’s no underlying issue, and the procedure is just a system check.
When the TSC light remains on after the system checks, that’s when you should be concerned. If it continues to illuminate, either you have turned off the traction control system in your car or it isn’t operating properly.
The causes of the traction control warning light coming on are poor road conditions, a defective wheel speed sensor, wiring problems, and ABS malfunction. Learn about Traction Control here!

What Does the Traction Control Light Mean?
In the event that one or more of your wheels lose traction while you are driving, the traction control system helps keep you in control of your car. The traction control light often signals that the traction control system is in use, which means that your vehicle temporarily lost traction while navigating a sharp curve, traveling on wet roads, or anything related.
But if the traction control light is on, it may mean the system is off or there’s a problem with it. You must exercise caution when driving when the traction control light is on.
This scenario happens most frequently when the roads are icy, snowy, or have other adverse conditions. Your driving habits also have an impact on how frequently you use your traction control system. The more recklessly you drive, the more traction control will be required to assist you.
Why does your traction control light remain on?
Here are the most common reasons why your traction control light comes on:
The TSC System is Turned Off
You may have inadvertently turned off the traction control system, which could explain why the light is on. Look for the TCS switch or button, then switch it on or turn it on. However, if the traction control light remains on, there may be a faulty or broken traction control component.
Poor Road Conditions
The most common reason your traction control light activates is when you are driving on a slippery surface. The TC light may momentarily turn on if you drive through an area with slippery roads.
This warning light alerts you to the activation of the traction control system. However, as soon as you regain traction, the light should turn off. If the light does not turn off, there may be a more serious issue.
Defective Wheel Speed Sensors
A defective wheel speed sensor, or multiple Defective sensors can cause the traction control (TC) light to illuminate. To measure each wheel’s running speed, wheel speed sensors are used. Each of these sensors informs the traction control system through its connection to the ECU.
When a sensor malfunctions, it cannot provide the ECU with accurate signals. Until you replace the defective wheel speed sensor, this issue will illuminate the traction control light.
Wiring Problems
Wires connect the main computer in your car to the speed sensors on each wheel. If these wires are damaged or corroded, your vehicle will think the wheels are rotating at different speeds, activating traction control. You can resolve this problem by having these wires replaced.
ABS Malfunction
The traction control system and the anti-lock braking system work together closely. TThese components rely on many of the same sensors and parts. Consequently, it’s possible that the traction control light may also illuminate if there is a problem with the ABS. Use your code scanner to identify which part is defective in order to determine the cause of the issue.
Wheel Speed Sensor Malfunction:
A faulty wheel speed sensor is by far the most prevalent cause of traction control issues in cars. Every wheel on your car contains a sensor that communicates to the ECM how fast it is spinning. Your traction system engages to correct the situation if one or more of those readings differ from what the other wheel speed sensors are providing.
However, if the wheel speed sensor is malfunctioning or producing inaccurate readings, your traction control will start performing strangely, which will cause the light to come on.
Faulty Steering Angle Sensor:
The steering angle sensor is another crucial part of your traction control system. This occurs because, when your car turns, the outside wheels spin more quickly than the inside wheels. Your steering angle sensor informs your Engine Control Module (ECM) about the vehicle’s steering position, which is a normal function.
However, the traction control system will detect a fault, and it may activate while you are turning if the steering angle sensor indicates that you are still traveling straight when you are actually turning.
Some manufacturers now combine the operation of the traction control and ABS systems and classify their faults as the same malfunction. In that situation, your dashboard can display an illuminated TCS light. Learn about the ESP Light here!

How do you reset the traction control light?
Here’s how to reset the traction control light:
Get an OBD-II scanner
Even if it’s just for minor repairs, an OBD2 scanner is a worthwhile purchase if you work on your vehicle. One can be bought online or at an auto repair shop near you. A less expensive device can be bought for $30 to $50, but a good OBD2 scanner will set you back several hundred dollars.
If your car was made before 1996, you’ll need an original OBD device, not an OBD2. The OBD2 will, however, work with any car made after 1996. You might also consider renting one from an auto supply store as an alternative.
Locate the diagnostic link connector (DLC) and plug it
Consult your car’s owner’s manual to find the OBD2 device connection port. The majority of the time, it is on the left side, under the steering wheel. You might need to remove a panel from your dashboard to reach it, even though most vehicles only have a cover on it. Connect the OBD2 directly to the DLC port.
Erase or reset the traction control light with the scanner
On the OBD2 device. Put in the necessary details. The next step is to select “systems” or “control unit” to get a list of the various vehicle systems. To turn off the warning light and restart your TCS system, find the TCS or ABS system, then select “erase codes” or “reset codes.”
Depending on your OBD2 device, you might need to utilize the model-specific key to read the codes. However, you can use the “auto scan” function to have your car automatically scanned to detect any issues.

Is It Safe To Drive With The Traction Control Warning Light On?
While driving with the traction control light on is typically safe, there are certain conditions where it is not. When the TCS light illuminates, which indicates that the system is functioning, only then is it safe to continue driving.
Your car may spin out and slide around on the road if you’re driving without traction control. It is advised that you keep your TCS active and functional in case adverse weather approaches. By doing this, you can always keep control of your car.
Driving while your TCS light is illuminated can be risky. The risk of losing control of your car increases. Without the TCS, your car might not handle slick roads as well as it should.
The TCS aids in controlling your car’s stability and traction.
Therefore, the safest course of action if your TCS light stays on is to have a qualified mechanic check the system and, if necessary, replace the TCS module.

FAQs
Can you drive with the TC light on?
While driving with the traction control light on is usually safe, there are several situations where it is not. Your entire braking system could be impacted if the traction control, anti-lock braking system, and red brake warning lights are illuminated.
Why is my TC light on in my car?
By maintaining traction on a slick surface, the traction-control light often indicates that your vehicle is in good working condition, but it could also indicate that certain sensors or wires are damaged. Take your car to a reputable auto repair shop at the first sign of trouble to keep yourself and many others safe while driving.
How do I turn off my TC?
If available, there must be a switch or button that displays a picture of a vehicle with wavy lines underneath it. To deactivate the traction control, press this button. The dash light should then show a steady yellow light to indicate that the TC is now off as a result of this.
What causes traction control to malfunction?
Traction control and ABS most often develop problems with the wheel speed sensors. These sensors are slightly vulnerable because of their moderate exposure to the elements. Dirt or other buildups may impair the magnetic operation of the traction control sensors or anti-lock braking sensors.
What causes the traction control to not turn off?
There may be several causes if the traction control light doesn’t go off. One cause could be that the traction control system’s fuse has blown. Another possibility is that the traction control sensors are faulty and keep the light on.
Does turning the traction control off make the car faster?
Maybe. A spinning wheel will be braked by a traction control system so that it can regain traction. Here’s the issue about acceleration: spinning wheels don’t move the car as quickly as traction-equipped wheels moving with less power.
Conclusion
In summary, the traction control light is a crucial signal in modern cars that significantly contributes to improving driver safety. When this light turns on, the traction control system is activated, which helps avoid wheel spin and loss of control, especially when driving in slick or difficult road conditions.
For safe driving, it is crucial to know the function of the traction control light and its numerous triggers, such as low traction surfaces or sensor problems. The traction control system will work properly if the underlying issues are swiftly addressed through maintenance and diagnostics, which will lead to a safer and more secure driving environment.
