For those who live in an area that experiences rain and snow more often than a clear sunny day, the traction control light is likely one of the most common dashboard lights illuminated on their vehicle. Virtually all vehicles are equipped with traction control and will display the traction control light (TC light) when the vehicle is driving on slippery terrains.
However, what if the traction control symbol appears despite not driving on a slippery surface? What if the traction control light stays on throughout the remainder of your drive? What if you discover both the ABD and traction control light on? There are several reasons why the traction control warning light may be appearing on your dashboard.
What is Traction Control?
Refer to DriveSmart’s What is Traction Control which discusses the traction control system and common questions such as “what does traction control do”, “how does traction control work”, “when to use traction control”, “how to turn off traction control” and “how to turn traction control on”. Understanding when to turn off traction control is extremely important for any driver, as the benefits of turning traction control off can be potentially life-saving in the scenarios we have outlined.
Why Is My Traction Control Light On?
If your traction control light won’t turn off, there are several reasons that could potentially explain why. The most common reason is that you are attempting to drive on slippery terrain. The traction control sensoris designed to monitor even the slightest slippage and may illuminate the dashboard symbol if it detects a slightly slippery road whether you physically noticed it or not. Typically, the light will briefly flash until the vehicle has regained full traction and has accelerated properly.
You also may see the symbol on your dashboard if your vehicle’s traction control system is disengaged. Simply locate the traction control button and enable the system. If you are unable to find it, refer to your vehicle’s manual.
Note: Most vehicles will automatically enable the TCS upon every start. If the system is healthy, shutting off your car and restarting it should re-enable the TCS.
Why Won’t My Traction Control Light Turn Off?
If you are not driving on a slippery surface and notice your TCS light continuously activating, there may be an issue with your anti-lock brake system or traction controlsensor. The traction control system and anti-lock brake system work side by side and provide stability to the vehicle. Since both systems utilize the same components, you may notice that your TC light is on, ABS light is on, or both are on at the same time.
Both systems are crucial safety systems that any driver should not drive without. If the light is not turning off, you should seek for service traction control specialists. Understanding how to fix traction control system units can be extremely complicated and should not be attempted on your own. Bring your vehicle to a certified mechanic who will be able to properly diagnose and repair your vehicle.
