Toyota vehicles are known for their high quality and durability. However, even the best cars can experience problems from time to time.
If you’re driving a Toyota and you see a TRAC Off light or VSC light turn on, it’s important to know what these lights mean and what steps you should take to address the issue.
In this article, we’ll discuss the meaning of these lights and how you can troubleshoot them yourself. Stay safe on the road – read on!
If you see the VSC Off and TRAC Off light come on, it means that your vehicle’s Vehicle Stability Control (VSC) system and Traction Control System (TRAC) have been disabled.
Toyota Vehicle Stability Control System and Traction Control
The Toyota Vehicle Stability Control system is designed to help drivers maintain control of their vehicles in potentially difficult driving situations.
The system uses various sensors to monitor the vehicle’s movement and can automatically apply the brakes to individual car wheels as needed to help keep the vehicle on its intended path. The system can also reduce engine power if necessary to help prevent the vehicle from losing control.
The Toyota Vehicle Stability Control system is standard equipment on most Toyota models, and it can be an important factor in helping to avoid accidents.
In some cases, the TRAC system has been shown to help drivers avoid collisions altogether. In other cases, it can help minimize the damage caused by an accident by helping to keep the vehicle under control during a crash.
An extension of the VSC system is the traction control system. This system helps to prevent the wheels from slipping when driving on slippery surfaces.
It can also help to reduce wheel spin when accelerating from a stop. The traction control system is standard on most Toyota models equipped with VSC.
The Toyota Vehicle Stability Control system is just one of the many safety features that are available on Toyota vehicles.
Other safety features include airbags, cruise control, seatbelts, and anti-lock brakes. These and other safety features help to make Toyota vehicles some of the safest on the road.
What is the Meaning of VSC Off and TRAC Off Light?
VSC Off and TRAC Off Light is a warning light that comes on the dashboard of a car. When you see the VSC Off light, it means the Vehicle Stability Control system has been turned off. The TRAC Off light is also connected to the VSC system.
TRAC stands for traction control. This system helps to prevent the wheels from spinning out of control when accelerating on slick roads. When this light is illuminated, it means that the traction control system is not active and the driver may not have as much control over the car’s traction.
If you see either of these lights or the check engine light come on while you’re driving, exercise caution and be aware of your surroundings. But, in some cases, it is a must to turn off VSC or traction control system.
For example, when your car gets stuck in the fresh snow or mud you need to turn off these systems to get out. This is because these systems will actually prevent your wheels from spinning, which is necessary to get traction and move the car.
Plus, these systems might also limit the power of your engine, making it difficult to get out of tough situations.
So, if you see either of these lights come on, don’t panic. Just be aware that you may not have as much control over the car’s traction as you normally would. And, if you need to turn off VSC or traction control, be sure to only do so when absolutely necessary.
What Tiggers TRAC Off Light to Come On?
Several things can cause the TRAC Off indicator to come on in Toyota vehicles.
1. You Replaced Brakes:
One reason the TRAC Off light may come on is if you’ve recently replaced your brakes. The new brakes may not be compatible with Toyota’s anti-lock braking system (ABS), which can cause the light to come on. The sensors of the traction control system are also located near the brakes, so if they’re not working correctly, they can also trigger the light.
2. Wheel Speed Sensor Issues:
Another common reason the TRAC Off light comes on is due to wheel speed sensor issues. The sensors are located in each wheel and they help the ABS determine how fast each wheel is spinning. If one of the sensors isn’t working correctly, it can trigger the TRAC Off light.
3. Low Tire Pressure:
Another possibility is that one or more of your tires has low pressure. This can trigger the light because it can cause the wheels to spin unevenly, which can throw off the ABS.
4. Dirty Sensors:
Dirty sensors are another common reason the TRAC Off light comes on. The sensors need to be clean to function correctly. If they’re dirty, they may not work properly and can cause the light to come on.
5. Loose Wires:
Loose wires can also cause the TRAC Off light to come on. The sensors and other components of the traction control system are all connected by wires. If any of those wires become loose, it can trigger the light.
6. Faulty ABS Control Module:
If the ABS control module is faulty, it can also cause the TRAC Off light to come on. The module is responsible for controlling the ABS. If it isn’t working correctly, it can trigger the light.
7. Traction Control System is Turned Off:
The traction control system can be turned off by pressing the TCS button on the dash. When the system is off, the TRAC Off light will be illuminated on the dash.
8. Brake Light Switch Issues:
Another common reason the TRAC Off light comes on is due to brake light switch issues. The brake light switch is located near the pedal and is responsible for turning on the brake lights when you press the pedal. If the switch is faulty, it can cause the TRAC Off light to come on.
9. New Tires:
If you’ve recently installed new tires on your Toyota, they may not be compatible with the traction control system. The new tires may have a different tread pattern or size than the old ones, which can throw off the system and cause the light to come on.
10. ECU Malfunction:
Finally, a malfunctioning ECU can also cause the TRAC Off light to come on. The ECU is responsible for controlling all of the electronic systems in the vehicle. If it isn’t working correctly, it can trigger the light.
How to Reset VSC Off and TRAC Off Light?
There are a few things you can do to reset the VSC Off and TRAC Off light.
- Turn the car off. Wait for a couple of minutes.
- Then turn it back on. And let the engine run idle for a few minutes.
- This will sometimes reset the light.
- If that doesn’t work, open the hood of your car.
- Disconnect the negative terminal of the battery.
- Attach it to the body chassis for a couple of minutes.

- This should do the job.
- Put your car in park mode.
- Locate the traction control button.
- It will be on the lower left side of your car’s dash.
- Press and hold it for about 20 seconds.
- You should hear a beeping sound indicating that the system has been reset.
- After that, start the car again. And see if the light is still on.
These are a few methods that can help you reset the VSC Off and TRAC Off light on your Toyota. Try one of these methods and see if it works for you. If not, then you may need to take your car to a mechanic to have it checked out.
How to Fix TRAC Off Light Issue by Performing Zero-Point Calibration?
One of the most common reasons why the TRAC Off light stays on is because the system needs to be calibrated. So, if the TRAC Off light stays on your dashboard even after you have tried resetting the system then you might have to employ a procedure called zero-point calibration. Let us describe the procedure in detail for you:
1. Park Your Car:
The first thing you need to do is park your car on a level surface and turn off the engine. While performing a zero-calibration procedure the car must stay stationary. You do not move the car during this procedure or else it will have to be performed all over again.
2. Disconnect Battery:
Then, you will have to disconnect the battery by removing the negative terminal. Once the battery is disconnected, wait for at least five minutes before doing anything else.
3. Reconnect Battery:
After five minutes, reconnect the battery and turn on the engine. Now, drive your car for at least 15 minutes so that the system can perform a self-check. After 15 minutes, turn off the engine.
4. Ensure Shift Lever is on P:
If your car is equipped with an automatic transmission, then you need to ensure that the shift lever is on P. If it is not, then shift it to P now. However, if you are driving a manual transmission car, make sure that the parking brake is engaged. Now, you will have to turn on the ignition switch without starting the engine.
5. Locate the OBD Port:
Once the ignition switch is on, locate the OBD port. The OBD port is usually located under the dashboard near the steering wheel column. Then, find the DLC 3 which is the black connector with 16 pins on it. DLC 3 is the diagnostic connecter circuit.
6. Use SST Diagnosis Check Wire:
This is the main step of the procedure. To connect the DLC 3, you will have to use the SST diagnosis check wire. The SST is a shorting connector that has two sharp points on it.
7. Insert the SST in CT and TS Terminals:
Now, you need to insert the SST into the CT and TS terminals. The CT terminal is the one that is closest to the edge of DLC 3 while the TS is the third terminal from the edge of DLC 3. After inserting the SST in both terminals, wait for 8 seconds. Repeat this process 3 to 4 times:
8. Check if the TRAC Light is On Now:
Once you have completed the process, check if the TRAC light is on now. It will come on as an indication that the calibration data has been erased and the system is ready to be recalibrated.
9. Turn off the Ignition Switch:
Now, all you need to do is turn off the ignition switch and remove the SST wire. Ensure that all terminals of DLC 3 are clear.
10. Turn on the Ignition Switch:
After that, turn on the ignition switch again. Now, start the engine and drive your car for at least 5 minutes to ensure that the system is functioning properly. After driving for 5 minutes, check if the TRAC Off light is gone. If it is, then the procedure has been successful.
If the TRAC Off light comes on in any of the Toyota car models, then it indicates that there is a problem with the traction control system. This system is responsible for helping the vehicle maintain traction on slippery or uneven surfaces.
If it is not working properly, then it can cause the vehicle to slip and lose control. It is important to have this system checked as soon as possible.
This article has outlined a procedure that you can follow to reset the system. However, if the light does not go off after completing this procedure, then it is advisable to take your car to a mechanic so that they can diagnose and fix the problem.

Frequently Asked Questions
Why do the check engine light and TRAC off light come on together?
Sensors are usually to blame when the check engine and TRAC off light come on together. The most common sensors that can cause this are the oxygen sensor, mass airflow sensor, or catalytic converter.
If any of these sensors are not functioning properly, it can trigger both the check engine and “TRAC off” light. In some cases, a loose gas cap can also cause both lights to come on. You can try replacing it with an OEM gas cap.
Are VSC Off and TRAC off light the same?
No, the VSC off light is not the same as the “TRAC off” light. The VSC off light comes on when the vehicle’s stability control system has been disabled. This system helps to keep the vehicle stable on slippery or uneven surfaces.
On the other hand, the TRAC off light comes on when there is a problem with the traction control system. This system helps to keep the wheels from slipping on slippery or uneven surfaces.
However, some Toyota models may have only one light of the two warning lights. In this case, the light will be labeled as either TRAC off or VSC off.
What does it mean when the TRAC light is flashing?
If the TRAC light is flashing, it means that there is a problem with the traction control system. It is an indication that the system is not working properly and needs to be checked. In some cases, the problem may be as simple as a loose gas cap. However, in other cases, it may be a more serious issue such as a faulty sensor.
Can I drive my car if the TRAC Off light is on?
If the TRAC Off light is on, it means that the traction control system has been disengaged. This can happen for a variety of reasons, but usually, it’s because the system has detected a problem.
It’s possible to drive with the TRAC Off light on, but you may notice reduced traction and handling. If possible, it’s best to have the issue checked out by a mechanic before driving too far.
Under what conditions traction control system is not useful?
There are certain conditions where a traction control system is not useful. For example, if a car is stuck in mud or snow, the traction control system will not be able to help. In addition, if a car is already sliding, the traction control system will not be able to prevent the car from sliding further.
How do I turn off the check engine light and TRAC?
