Your Toyota dashboard has a variety of warning lights that let you know when something is wrong. When the TRAC OFF light comes on, it can cause some alarm, but it doesn’t need to. In many cases, there’s nothing abnormal occurring.
In this article, I cover the meaning of the TRAC OFF light and show you what causes it. I also outline some fixes you might want to try and tell you when you should manually turn off the system.
What Does The TRAC OFF Light Mean?
The TRAC OFF light indicates that the Traction Control system is turned off on your Toyota vehicle. In some cases, the light indicates that you have turned the system off manually, while other times, it can show that the traction control is facing a malfunction.
If you have pushed the button for the traction control system, you may also see the VSC (vehicle stability control) light. On the other end, when there’s a malfunction, it’s common for the Check Engine Light or other MILs to come on the dashboard, further indicating what the problem might be.
The TRAC OFF light can look different depending on what model you drive. In some cases, you will see the letters “TC” on the dashboard. Otherwise, there could be an image of a vehicle with lines that are bending opposite of the tires.
What Causes The Trac Off Light?
The most common cause of a TRAC OFF light is that you pressed the TRAC OFF button in your Toyota vehicle by mistake. If you see the TRAC OFF light along with a check engine light or other warning lights, there may be a problem with the traction control system.
Here is some more detailed information on the causes of the TRAC OFF light.
1. You Turned it Off
The main reason that the TRAC OFF light comes on is due to you turning the system off by mistake. You can hit a button to turn the traction system on or off. When it’s off, the dashboard will indicate this, so you know that it needs to be reactivated. Hitting the switch is all that’s needed to turn it back on.
Many times, when you physically turn off the traction control system, the vehicle stability control will also deactivate. You could also see the VSC light on the dashboard or a picture of a vehicle sliding on the road with the words OFF listed. This above is usually the only reason for a TRAC OFF light.
If you see the Trac Off light along with a check engine light on your dashboard, it could be a sign that there is a problem with your traction control or engine control system. This can be caused by any of the following issues.
2. Poor Road Traction
If you see a blinking traction control light on your dashboard, it could mean that you are driving on a slippery surface and that the car is skidding. If this is the case, the light will only come on temporarily until the road gets better.
The most common cause of this condition is because of snow or ice. However, even a good amount of rain can lead to reduced traction, which leads to a temporary malfunction.
3. Defective Wheel Sensor
Your car is equipped with wheel speed sensors that feed data to the engine control unit and the traction control system. These sensors are responsible for measuring each wheel’s rotational speed.
If there’s a failure with the sensor, the system will receive data that appears inaccurate. For safety reasons, the traction control system will shut off so as not to malfunction.
4. Failed Steering Rack System
Hydraulic fluid gets pumped into the steering rack, so you can spin the wheels with ease while driving. To maintain traction, controlled steering is imperative. Modern steering systems use many different sensors for the system to function properly.
If there’s a failure in the steering rack or any of the sensors, such as the steering angle sensor, you could lose traction control functions. Until the problem is resolved, the traction control system will remain deactivated to ensure safety.
5. ABS Malfunction
The anti-lock brake system also plays a big part in your on-road handling. If there’s a malfunction with the ABS, you could see the traction system shut off as well.
The problem could be related to the ABS controller. However, the wheel speed sensors are also part of the ABS system, which we discussed earlier.
6. Computer Malfunction
Modern vehicles have been built with many different computers, each running a different set of operations. When a computer malfunction occurs, the traction control system can act up and turn off automatically.
When a computer malfunctions, it doesn’t normally just affect one system. For this reason, this is one of the most unlikely options on the list, but also most noticeable because there should be several other symptoms happening at the same time.
How to Fix the TRAC OFF Light?
To fix the TRAC OFF light, it is enough to just press the TRAC OFF button again to activate the system in most cases. It may also help to restart the vehicle by cycling the ignition. If these steps do not work, you will need to read the trouble codes with a scanner.
Here is some more detailed information on how to fix the Trac Off warning light:
1. Turn it On
If you’ve turned the traction control system off by mistake, it’s simple to fix the problem. You simply need to push the traction control button and turn it back on.
Usually, the TRAC OFF button is found to the left of your steering wheel in most Toyota models. Push the button again and see if that resolves your problem. This would be the easiest solution.
2. Restart Vehicle
A simple reboot can fix a lot of problems. Just like you would with a computer that’s acting up, you can turn off the vehicle and restart the engine once again.
If the traction light remains off, the problem has resolved itself and you have nothing to worry about. If it hasn’t, you should move on to the next steps to figure out what’s going on.
3. Read DTCs
If the other suggestions haven’t worked or there are other lights on the dashboard, you should read the diagnostic trouble codes with your scanner. This step is imperative if the Check Engine Light comes on with the TRAC OFF light.
With the code scanner, you should gain a better idea of the fault. We recommend repairing anything that shows up before worrying too much about the TRAC OFF light. It’s possible that the fix will resolve the traction control system problem.
4. Visit Mechanic
If you are unsure what the trouble codes mean or you can’t find the problem, go ahead and reach out to a professional. It’s possible that there’s a more advanced issue occurring that you won’t know how to repair.
While you will have to pay more to have a professional handle the repair than if you did it yourself, you know the job will get done. You can choose an independent mechanic to handle this diagnosis or pay a little more to visit your local dealership.
When Should TRAC Be Turned Off?
If you are driving off-road or driving on a very muddy or snowy road, you may want to turn off the traction control system. With the system on, power from the engine to the wheels is reduced, which only adds to the problem.
By turning off the TRAC system, you can rock the car, truck or SUV free from where it sits. Push the button in and look for the sign on the dashboard. Once you get out of this situation, you can push the button again to re-enable it.
The reason that there’s a button to turn off the TRAC system is due to the times when it becomes necessary to disable it. Under normal driving conditions, it’s best to leave the system engaged.
