One of the systems that use this information is the VSC system, and if there is something wrong with the brake light switch, it will store a fault code and turn on the VSC light on your dash. Its job is not only to turn on the brake lights when you press the brake pedal, but also to provide information to many control modules when you press the pedal. The brake light switch or brake pedal switch is located on your brake pedal. RELATED: 4 Signs of a Bad ABS Wheel Speed Sensor (Replacement Cost) 3. The steering angle sensor is also used by both the ABS system and the VSC system, and if this sensor gives the wrong signal to these control modules, it will turn on the VSC light. It could also be a wiring problem between the sensors and the ABS control module. It is also possible that there is a problem with the ABS reluctor rings from which the sensors measure the speed. These ABS sensors are located at the wheel spindle hubs and are therefore also very exposed to water, rust and dirt and are therefore prone to failure.īecause the VSC system uses this information, it will display a VSC light on your dashboard if there is a problem with an ABS sensor. It is not only the ABS control module that uses this information but also other important control modules such as the ECM and TCM. The ABS sensors are located at each of your car’s wheels to measure wheel speed. Learn more here about the possible causes: Check Engine Light – Meaning, Causes (& How to Fix It) 2. However, there are many different parts that can cause this problem as well, so that being said, it’s important to read the codes with a scanner first if you see both warning lights on your dash. Some of the common engine issues that could cause a VSC light are: You need to read this trouble code to find out what is causing the warning lights. When the check engine light and VSC light illuminate on your dashboard, there will be a trouble code stored in the engine control module. Therefore, it won’t be possible to just guess what causes it. Modern engines have many different sensors, actuators and other parts that can result in a check light, which will also result in a VSC light if you have a Toyota or Lexus. This is especially true if you also see a Check Engine light on your dashboard along with the VSC light. The most common reason for the VSC light to come on is due to an engine problem. Here is a more detailed list of the most common causes of a VSC warning light: 1. Since the VSC system is integrated with the engine management and brake control system to control your car’s traction, there are quite a lot of things that could go wrong. It can also be caused by ABS problems such as a faulty ABS sensor or bad wiring. If this is the case, you’ll see the VSC light along with a check engine light on your dashboard. The most common cause of a VSC light is engine problems. RELATED: Traction Control Light (TCS): Meaning, Causes (& How to Fix) What causes the check VSC system light? If you have a newer Toyota or Lexus car, you may also see a “Check VSC system Light” message on your dashboard instead of the regular VSC light. If you see the “VSC OFF” warning light on your dashboard, it means that the traction control is completely disabled and the traction control will not work if you lose grip. VSC works together with ABS and other control modules. Traction control helps your car to maintain its grip by reducing the engine power sent to the wheels and sometimes even applying brake force through the ABS system. VSC stands for vehicle stability control, and it is Toyota’s and Lexus’ systems for handling traction control. It may also appear if you accidentally pressed the VSC button. The Check VSC System Warning or VSC light indicates that there is a problem with your traction control system, and your VSC and ABS systems will be temporarily disabled. Let’s begin! What does the VSC Light mean? We will also go through some of the common questions about the VSC light. In this article, we will go through what the check VSC system or VSC light means, what causes it and how you can fix it yourself. VSC reduces the number of traffic accidents in rainy, foggy, and snowy weather conditions by quite a lot and therefore, it is important to fix your VSC system as soon as you see a VSC light on your dashboard. When the VSC system senses that your car is losing traction, it will automatically remove engine power from certain wheels to correct the course of your vehicle to prevent an accident. The Vehicle Stability Control (VSC) is installed in many Toyota & Lexus cars, and its job is to stabilize your car if it slips in severe weather conditions.
