A VSC system cuts engine power to some wheels to correct your vehicle’s movement and prevent accidents. It’s important to fix the VSC system as soon as possible to reduce the likelihood of accidents in foggy, rainy, and snowy weather.
The VSC light on your car’s dashboard indicates a problem with the electronic stability system, which helps keep your car safely on the road in hazardous conditions.
The VSC system uses sensors to monitor the vehicle’s movements and stability, intervening by applying brakes and adjusting engine power if loss of traction, oversteer, or understeer is detected.
Many Toyota owners frequently notice the VSC OFF light on their dashboard. That is why you need to know more about the VSC light indicator its causes and how to fix it.
The causes or reasons why or VSC light comes on include engine problems, defective ABS sensor, wiring issues, or maybe you mistakenly turning it on. Learn about traction control lights here!
Now, let’s go deep to explain what a VSC system is, what the VSC light means, how it works, why it comes on, and how to fix and reset it!

What is a VSC system in a car?
VSC stands for “Vehicle Stability Control” and is a system used in Toyota and Lexus vehicles to reduce or eliminate power to the wheels, helping maintain traction and control. It applies brake pressure to up to three wheels to keep the car traveling in the direction of its wheels.
Since 2012, all new U.S. cars have been required to have VSC/ESC, which is different from traction control and focuses on improving traction rather than steering control.
What does the VSC light mean?
The “VSC light” or “check VSC system” message on the dashboard indicates a traction-related problem in the vehicle, potentially with the VSC or ABS system. If the VSC light continues to illuminate or other warning lights come on, it’s important to have the car checked.
The “VSC OFF” warning light indicates that the traction control is deactivated, and a “Check VSC system light” message may appear in newer Toyota or Lexus models. Pushing the VSC button turns off the VSC system, and the location of the button varies by Toyota model.
How Does a Car VSC System Works?
The VSC system uses sensors to monitor the vehicle’s movements and stability, intervening by applying brakes and adjusting engine power if loss of traction, oversteer, or understeer is detected.
When a fault is detected, the VSC light on the dashboard alerts the driver, indicating issues such as faulty sensors, braking system problems, or traction control issues.
It’s important to have the vehicle inspected and repaired by a qualified technician when the VSC light is on, as the stability control function may be compromised.
The VSC light serves as a valuable warning indicator for drivers to address potential issues with the vehicle’s electronic stability control system. Learn about VSC light here!

What Causes the VSC Light to come on?
Below are the common reasons why your VSC light comes on:
The VSC Button was accidentally pressed
The majority of vehicle models with a VSC system also have a button to turn the system off. You should verify this again before drawing any conclusions because it’s always possible that you accidentally pressed this button. But if you press the button, you’ll probably get a VSC OFF light instead of the typical VSC warning light.
Engine problems
Issues with the engine are the most common cause of the VSC light to illuminate. This is especially true if your dashboard also displays a Check Engine light.
Modern engines include a wide range of sensors, actuators, and other components that might cause a check light, which, if you drive a Toyota or Lexus, can also cause a VSC light. As a result, it won’t be able to simply speculate about its origin.
Defective ABS Sensor
Each wheel on your car has an ABS sensor that measures wheel speed. Other significant control modules, such as the ECM and TCM, as well as the ABS control module, make use of this data.
The VSC light will appear on your dashboard if there is an issue with an ABS sensor because the VSC system makes use of this data. Another possibility is that the ABS reluctor rings, which are used by the sensors to gauge speed, are having an issue.
Wiring Issues
There are several electronics in modern cars, and wiring is required for each and every one of them. Additionally, because of this, wiring issues are becoming a pretty prevalent issue with contemporary vehicle models.
Unfortunately, without the necessary expertise and understanding, wiring issues can be rather challenging to identify. So if you believe there is a wiring issue with your car after checking everything else, it could be a good idea to consult a professional.
How to Turn OFF VSC Light?
The VSC (Vehicle Stability Control) system is a crucial safety feature that enhances vehicle stability and control. It is not advisable to turn off the VSC system unless necessary, such as in certain off-road situations.
If you still want to turn off the VSC system, locate the VSC button or switch, engage the VSC Off mode, and confirm deactivation if required.
Keep in mind that disabling the VSC system can affect vehicle stability, so it should only be done when necessary, such as driving on loose surfaces.
The VSC system will usually reactivate automatically when the vehicle’s engine is restarted or when it surpasses a certain speed threshold.
How can you Fix the VSC light?
Here’s how to fix/turn off the VSC light in a quick and simple way:
- Be sure to come to a complete stop in a very secure area. Ideally, put the vehicle in park.
- Locate the VSC button. Depending on the model year of the Toyota, the button will either be on the dashboard just above your knees or close to the gear stick.
- Press and hold the VSC button for a few seconds.
- Both the TRAC OFF and VSC OFF indicator lights will turn on. Now, both systems are off.
- Once again, press the VSC button. The systems have now been reengaged and both lights will go off.
The VSC light ought to go off as a result of the above process. However, if it persists, it is likely that there is an underlying problem with the vehicle that needs to be attended to. So it’s recommended that you visit a certified mechanic shop.
Can you drive with the VSC light on?
While the VSC OFF light is on, it is safe to drive your Toyota, but we advise caution, especially in bad weather. Your Toyota or Lexus dashboard’s VSC warning light might signal a number of traction-related problems.
The rotation speed sensor, the wheel speed sensors, or the steering angle sensor may all be at fault. If the steering rack is broken, that can potentially be the problem.

Bottom Line
Understanding the VSC (Vehicle Stability Control) system and its warning light is essential for maintaining vehicle safety and performance. By following proper diagnostic procedures and addressing any issues promptly, you can ensure the VSC system functions optimally.
Remember to check your vehicle’s manual for specific guidance and seek professional assistance if needed to maintain the efficiency of your vehicle’s stability control. Prioritizing safety and proactive maintenance enhances overall driving safety and stability.
