The Vehicle Stability Control (VSC) warning light signals a problem with your traction control system, which will result in a temporary loss of VSC and ABS functionality. Additionally, it can show up if you unintentionally pressed the VSC button.
Vehicle stability control, or VSC, is how Toyota and Lexus handle traction control. By lowering the power applied to your wheels, traction control aids in maintaining traction.
The VSC and ABS collaborate. Snow might obstruct the ABS sensors when you’re driving in blizzard conditions, turning on the check VSC system light.
Upon noticing the “When you see the VSC OFF indication on your dashboard, it implies that your traction control is entirely disabled and won’t activate if you lose traction.
Those who drive more recent vehicles can also view the “Instead of the VSC light, check the VSC system Light message on your dashboard.

How do you repair a Toyota’s VSC light?
Vehicle Stability Control, or VSC as it is commonly known, is the stability control system used in Toyota automobiles. By lowering or eliminating the power provided to your wheels, stability control aids in the maintenance of traction and control in your vehicle. By automatically providing brake pressure to up to three wheels, it achieves this. The system’s main objective is to keep your car traveling in the direction of its wheels. Since 2012, at least in the USA, it has become a necessary safety requirement. Naturally, VSC OFF denotes that your Toyota’s stability control is turned off.
VSC Light Easy Fix
Depending on the model year of the Toyota, a button with the same icon as the light in your gauges will be located either next to your shifter or next to your steering wheel. When you’ve found it:
- Ensure that you have come to a complete stop. If you can, put the car in park.
- For a few seconds, hold down the VSC button.
- The indicator lights for TRAC OFF and VSC OFF will turn on. Now both systems are off.
- Once more, press the VSC button. As soon as both lights go out, the systems are back in operation.
If the VSC OFF light is still on, there can be a glitch in your car’s computer or a problem with the VSC system. Bring your car to a Toyota service location near you so a qualified technician can check the codes and identify the problem. Although it is safe to drive your Toyota even with the VSC OFF light on, we advise caution, especially in bad weather.

Can you drive with the VSC and check engine lights on?
While driving with a VSC light on is possible, it is not recommended for safety reasons. In the event of a rainfall or slippery conditions, your car won’t have any driving assistance if the VSC light is on since the vehicle stability control system is off.
Although it is possible to drive with the VSC light on, doing so is strongly discouraged. Pay particular attention to your driving and drive with extra caution on curved roads and in bad weather if your VSC must be turned off or is damaged.
What could activate the VSC light?
There are numerous things that can go wrong because the VSC system is connected with the engine control and the brake control systems to control your car’s traction.
A bad accelerator pedal, faulty throttle body, faulty ABS sensors, or a faulty mass airflow sensor are the most typical reasons of a VSC light.
The quickest way to determine what set off your VSC light is to use a diagnostic scanner to read the issue code memory.
How much does a VSC repair cost?
Lexus VSC repairs would cost between $200 and $300. But that depends on what made the light come on. Vsc collaborates with the ABS and other auto parts. Therefore, it is best to find the problem before discussing how much to remedy it.
Why did my check engine and traction control lights illuminate?
A system bulb check is initiated as the ignition key rotates through the phases of Off, Run, and Start. As the car starts and runs, the traction control system light should come on for one to two seconds before going out. If the indicator continues to illuminate, either the traction control system is malfunctioning or the system has been disengaged.
What does it signify if your traction control and check engine lights are on?
This indicator turns on when the computer notices that the traction control system may be having a problem. The traction control system keeps an eye on the car’s steering and stability and activates when it notices a loss of traction. Electronic sensors are used at each of the four wheels to accomplish this, and they convey steering performance and stability in inclement weather conditions to the Powertrain Control Module (PCM). The traction control system prevents the car from sliding by slowing the engine and selecting which wheel to apply braking pressure to. Together, the traction control system and the anti-lock braking system keep the car stable. The computer makes decisions about how to operate the traction control system or the anti-lock braking system to best control the vehicle when necessary using the data it receives from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle. When the warning indicator light on the dashboard illuminates, there may be a number of problems present, including faulty steering angle sensors, faulty rotational speed sensors, and faulty wheel speed sensors as well as a steering rack issue. The traction control system may occasionally just need to be reprogrammed. Additionally, certain vehicles may enter limp mode, which prevents acceleration above around 30 mph, when any of these symptoms are found. I suggest having a specialist from YourMechanic visit your location to examine and diagnose your vehicle.
Why are my TRAC off and check engine lights on?
I’m here. The traction control is indicated by the Trac Off light. For different reasons, the computer has disabled the traction control. It’s possible that the controller, the speed sensor for the car, or the wheel speed sensors aren’t working properly. Check the computer’s stored codes when the engine light is on to get a head start on figuring out why your traction control isn’t working. If you require additional help with the Trac Off light and the engine light being on, then get in touch with a specialist, like one from Your Mechanic.
Is traction control the same thing as VSC?
The distinction between stability control and traction control is comparable to that between a GED and a master’s or doctoral degree in automotive safety. Traction control is traction control with improved tools and increased vehicle knowledge (computer programming) (a more powerful processor and more electronic sensors).
The 1971 Imperial undoubtedly introduced the anti-lock brake system, or ABS as we now know it. The Buick Riviera debuted MaxTrac in the same year, a primitive traction control system that didn’t use brakes but instead compared front wheel speed with gearbox output speed to identify spin and cut engine spark until the front and rear wheel speeds were equal. This reportedly caused some spectacular backfires because there was no mechanism to lower the amount of fuel running through the carburetor.
However, America’s first experience with a system like the ones we know today came in 1995 with help from Bosch on the Mercedes-Benz S600 coupe. Stability control, also known as active trace and traction control, then Active Skid and Traction Control (ASTC), sort of made its debut on the 1990 Mitsubishi Diamante sold in Japan. Let’s look at and contrast the current systems.
How does the VSC system work?
Vehicle stability control, or VSC for short, is an electronic system intended to lessen the loss of vehicle control by monitoring the steering direction and the actual direction of the vehicle. The system then applies braking force and may even reduce power to particular wheels in an effort to stop a skid.
Reason #1Faulty Wheel Speed Sensors
If you’ve read our description of the traction control system’s operation. So you should be aware of the reasons why it can malfunction due to a bad wheel speed sensor.
They are in responsible of notifying the system when a loss of traction occurs, therefore if one is malfunctioning, the TCS light will probably come on.
Options For Replacing A Wheel Speed Sensor
You can spend between $135 and $250 to have an expert identify which sensor is defective and repair it. Alternatively, you may replace it yourself for just over $100.
If you choose to do it yourself, an OBD2 scanner can typically identify which wheel is at fault. A $20100 unit should be adequate because you shouldn’t need anything fancy. You can also bring your car to a nearby parts supplier, and they’ll probably read the code without charging you.
Reason #2ABS System Malfunctioning
The functioning components of the TCS and ABS systems frequently overlap. As a result, if your ABS isn’t working properly, the traction control light can come on. You’ll probably notice an ABS light in addition to a TCS light in this situation.
Options For Replacing An ABS Control Module
This problem is most likely the result of either a bad ABS control module or a bad wheel speed sensor. Again, you can identify which is acting strangely by utilizing an OBD2 scanner.
If the problem is the control module, you have two options: have it fixed professionally for roughly $1,000 or do it yourself for about $800.
You can find instructions for changing an ABS control module in the video below, but you should be aware that it is for a 2005 Chevrolet Blazer.
Reason #3TCS Needs Reprogrammed
Your traction control light may just need to be reprogrammed if it repeatedly illuminates when it shouldn’t. Consider it pure coincidence that something happens for no apparent reason.
Options For Reprogramming A Traction Control System
There aren’t many possibilities for doing your own TCS system reprogramming. You will regrettably need to take it to a qualified mechanic if this is the problem.
Fortunately, the actual task shouldn’t take more than an hour. You should budget $100 for the diagnostic price and an additional $50 to $100 for labor.
Traction controldoes it impact transmission?
The differential, gearbox, and/or wheel speed sensors are some of the sources of input that the traction control module compares and analyzes. The module recognizes lost traction if the value from one or more sensors is quicker than the actual speed of the vehicle.
The anti-lock braking system and hydraulic brakes are coordinated by the traction control module to pulse the brakes up to 15 times per second. Until you let off the throttle pedal or your tires stop skidding, the module will continue to operate.
In order to help you regain traction, some car systems will actually reduce the engine power to the skidding drive wheels.
