The vehicle stability control is a system in many Toyota and Lexus cars that is designed to prevent the car from sliding and slipping during tough climates. During times of extended precipitation, the roads will become slippery and cause problems for tires trying to gain friction. The system that is in charge of preventing your vehicle from sliding around the road is the vehicle stability control system, or VSC. The purpose of the VSC system is to apply the brake to the car’s wheels and prevent the car from skidding on the road.

How Does The VSC System Work?
The VSC is in charge of providing traction for your specific Lexus. The car’s internal traction control system is regulated by the VSC. when you drive on slippery and unstable roads, you lose traction and the car can slide around. The system comes to life and gives you better steering control to maneuver the tricky roads. All of the wheels in your car will have sensors that directly communicate with the Lexus’ powertrain control module.
The powertrain control module, or PCM, is a control unit used in the Lexus vehicles. It is a combined control unit consisting of the engine control unit and the transmission control unit. The engine control unit, or ECU, controls actuators in the internal combustion engine to ensure optimal performance. The transmission control unit controls automatic transmissions in most modern cars. The unit uses sensors within the vehicles to determine when and how to change gears for the best possible performance. The powertrain control module is essential in the workings of the vehicle stability control system.
If you experience issues with the control of steering, the VSC will reduce the engine speed in order to prevent excess motion. In addition, the VSC will give more braking power to the wheels that need friction and braking power the most. The wheel sensors provide information about the motion and rotation of the wheels in order to determine which wheels need the braking power. If you notice the VSC light comes on, you might be having problems with your sensors or the steering system.
How To Fix Your VSC Light
If you are sure that your VSC light has come on by accident and there is nothing wrong with your car, there is a button on your shifter or steering wheel that has the same icon as the light that comes on on your dashboard. After you have located the VSC button, then there are a few steps you need to take.
First, you need to make sure that you are at a complete stop. Put the car in park and turn on your emergency brake to ensure the car won’t move during this fix. Next, press and hold the VSC button for a few seconds while you are in the car. Next, the TRAC OFF and VSC OFF lights will come on. This means that both of these systems are now off. Lastly, press the VSC button once more. Both lights will then shut off and the systems are now restarted and working again.
If the VSC OFF light is still showing up, then this means you could have a computer or internal error in your car’s computer or VSC system. Take your vehicle to a trusted technician or Lexus service center to have a certified technician run codes and diagnose the issue. It is safe to drive your car while the VSC light is still on. However, you should still take your car in for a diagnosis as soon as possible.
What Makes The Check VSC Light To Come On?
Sometimes when the VSC light comes on, it is also accompanied by the ABS light or check engine light. The ABS works in tandem with the VSC, and is often lit-up at the same time the VSC light will appear. ABS is the anti-braking system that can lock the brake sensor. The purpose of the ABS system is to measure the speed of the tires and then transfer this information and data to the car’s engine control module.
The ABS light might come on for a reason that is specific to the anti-lock brake system. It will usually come on as the letters ABS, or the letters ABS surrounded by two circles. The anti-lock brake system is in charge of pulsing your brakes in certain situations. If the ABS sees that your wheels might lock up during use, it will activate and deactivate individual brakes and wheels.
If there are any issues with your ABS system that can prevent it from performing the functions required, then the ABS light will come on. There are a few key reasons the ABS light will come on, and some of them are tied to the VSC light in your Lexus illuminating as well.
Why Will An ABS Light Come On?
The two main reasons that your ABS light will come on in your car is to test the bulb function and lifespan, and to alert the driver that there is a fault within the anti-lock brake system. Some of the common reasons for the light to come on due to a fault is that there is low fluid, a faulty control unit, bad speed sensor, a failed pump, or solenoid malfunction.
If the engine control module notices that there is skidding occurring and the wheels are not spinning the same speed, the ABS system will lock up some of the wheels and prevent the car from skidding on the slippery road. The ABS system usually consists of a coil housing a magnet and a ring. A signal is generated by the magnetic field and is then transferred into a digital signal. After adding VSC to the Lexus, drivers are able to gain better control of their cars.
So The VSC and ABS Light Are On Together. What About The Check Engine Light?
A common issue with many Toyota and Lexus vehicles is that the check engine light will come on at the same time the VSC OFF light turns on. The check engine light is meant to indicate any issues with the malfunctions about the engine, or anywhere that is connected to the engine directly. VSC refers to the vehicle stability control, and directly affects the traction of the tires.
If this happens, it doesn’t necessarily mean that there are issues with the traction control system. It could mean that the system is turned off and won’t work until the check engine light is fixed. The issue with the VSC OFF or Trac Off light coming on is that your car could slide on the road during wet conditions.
Sometimes the VSC OFF and check engine light may come on at the same time from something more minimal in your vehicle. A loose gas cap could be the culprit behind the combination o f both lights being on. The way to figure out what is really wrong is by using an OBD2 scanner to read the codes associated.
ASR System and The VSC Light In Your Lexus
Another system that is used in tandem with the VSC is the acceleration slip regulation. The acceleration slip regulation, or the ASR, is in charge of preventing the driving wheels from spinning unnecessarily. It is also in charge of regulating when the power coming from the engine prevents the wheels from gaining proper traction, and causing unnecessary wheel spin. The ARTS can improve directional control, due to gaining better traction while cornering at high speeds. If the ARS and VSC are working together, an issue with either one of these systems can cause the VSC light to turn on in your Lexus.
The system uses the ABS speed sensors to determine if one of the wheels is rotating quicker than the others. The ARS automatically determines if the individual brakes are sufficient for the vehicle to reinstate grip, or maintain the same spinning speed as the other wheels. The ASR sends communication signals to the engine management system, and the power is reduced.
The dynamic stability control is activated and turned on when you begin driving through unstable roads, allowing one or more wheels to slip, and increasing the traction to specific wheels. The dynamic stability control, or DSC, is in charge of improving the vehicle’s stability by reducing the loss of traction. The DSC automatically takes control when the vehicle begins skidding on the road.
The DSC system controls the engine output and the braking force individually applied to each individual wheel by using the combined control of the ABS and traction control system. This aids in maintaining stability in the wheels, even while you might be in dangerous or hazardous conditions. The DSC works in tandem with the VSC in your car, and can aid in the VSC light is on in your Lexus.
ESC System and The VSC Light
The ESC, also known as the electronic stability control, is a mechanism that is used to aid in traction control. This system works as a team with the ABS and VSC. if there is an issue with the wheel traction or with any of the aforementioned issues, the VSC light might come on in your Lexus. VSC systems work on various surfaces to ensure a variety of abilities in extreme conditions.
The ESC can take control of the car before a driver knows what is happening with the wheels when working together with a VSC system. The system is able to estimate how long the skid will occur and the direction, before giving braking power to the necessary wheels. The car will then be able to be controlled by the driver, since the braking power is properly applied.
How To Reset The VSC Light
If you have a scan gauge, then you can easily reset your VSC light in the Lexus. A scan gauge can provide you with accurate and timely data about your vehicle’s fuel economy, fuel used, and the cost of fuel for each one of your trips. In addition, the scan gauge will provide information on the cost per mile, gallons per hour, and other fuel data.
First, switch on the engine to ACC and press the odometer until it reads the mileage of your car. Switch off the engine completely and let it sit for a minute. After it has rested, turn the engine on again, and press the odometer simultaneously. By pressing the odometer and turning your engine back on, it can clear the VSC light.
If this procedure doesn’t work, then you might be having issues with the sensors in the wheel giving accurate information to the car’s computer. The sensors can undergo some wear and tear over time, and can provide faulty readings.
What If I Don’t Know How To Fix The VSC Light In My Lexus?
If the VSC light is on within your Lexus, then the other lights will typically come on as well, such as the check engine light and ABS light. These systems work together in order to prevent your car from slipping on a wet road or unstable conditions. When a VSC light comes on, there can sometimes be an issue with the other systems in charge of stabilizing your car.
If you determine there are issues with your tires, your braking system, or your engine since additional lights came on at the same time as the VSC light, then you might have other issues in your car you need to repair or replace. If you don’t have the money to spend on the necessary replacements, then you might need another option.
The best option for you in this scenario is to bring your car to a reputable location and exchange your vehicle for money. Remove all non-metal components from your car, and sell the parts that can gain you some extra cash. After this, bring your vehicle to CashCarsBuyer, where they will provide you with a fair quote, and a substantial sum to put towards a new and safe car.
