VSC stands for “Vehicle Stability Control,” which is the stability control system that Toyota uses in their vehicles. The VSC light on a Toyota Corolla indicates that there is a problem with the vehicle’s traction control system.
The purpose of the VSC system is to help the vehicle maintain traction and control by reducing or completely cutting power sent to the wheels. It automatically applies brake pressure on up to three wheels.

How does the VSC system work in a Toyota Corolla?
The Vehicle Stability Control system in a Toyota Corolla is an electronic system designed to help the driver maintain vehicle control under adverse conditions. The VSC system works by using sensors to detect when the vehicle is losing traction or control. When this happens, the system automatically applies the brakes to the appropriate wheels to help the driver maintain control of the vehicle.
The VSC light on a Toyota Corolla indicates that there is a problem with the vehicle’s traction control system. This could be caused by a number of traction-related problems.
Why is my VSC Light on?
The VSC light can be caused by a number of traction-related problems, such as an issue with the rotation speed sensor, the wheel speed sensor, or the brake pressure sensor.
How do I turn it off?
Most vehicle models with a VSC system have a button to turn the system off. This can be useful in certain situations, such as when driving on sand or snow, where the VSC system may interfere with the vehicle’s ability to gain traction. Although it is safe to drive a Toyota Corolla even with the VSC OFF light on, caution is advised, especially in inclement weather.
VSC System vs. Traction Control System in a Toyota Corolla
The VSC system and the traction control system in a Toyota Corolla are related but have different functions. Here is some information to support this:
VSC System:
VSC helps control the vehicle while driving and cornering by reducing or completely cutting power sent to the wheels and automatically applying brake pressure on up to three wheels. It’s largely connected to Traction Control (TRAC), both of which help to keep the car stabilized when driving on slippery roads or in other adverse weather or road conditions.
Traction Control System:
Traction control limits wheel spin on acceleration to help the vehicle maintain traction and control. Traction control and VSC use many of the same components, such as the ABS system, but have different functions. But traction control is a simpler system than VSC and is an evolution of the system.
What to Do When Your VSC Light Comes On
If the VSC light comes on in your Toyota Corolla, here are some steps you can take:
Check the VSC OFF button: If the VSC OFF button has been pressed accidentally, it may cause the VSC light to come on. It’s usually located near the shifter or steering wheel. Press it to turn the VSC system back on.
Check other warning lights: If other warning lights on the dashboard come on along with the VSC light, it may indicate a problem with the vehicle’s traction control system. In this case, see a professional mechanic.
Check the vehicle’s computer: If the VSC OFF button has not been pressed and there are no other warning lights on the dashboard, it may be a bug with the vehicle’s computer or a malfunction with the VSC system. In this case, it is recommended to take the vehicle to a local Toyota service center to have a certified technician run the codes.
Drive with caution: Although it is safe to drive a Toyota Corolla even with the VSC OFF light on, caution is advised, especially in inclement weather.
If the problem persists, have the vehicle checked by a Toyota Dealership.
