When an unfamiliar symbol springs up on your car’s dashboard, it can bring feelings of confusion and worry unless you know what the symbol is trying to tell you. So if you see a little light with the letters “VSC” flash on your dash, don’t panic. Most likely, the car is just letting you know that it has engaged a safety system designed to help keep you on the road. Here’s what you need to know about your VSC system and how it impacts your car’s performance.
What Is A VSC System?
The Vehicle Stability Control system is a relatively new technology currently found in select Lexus and Toyota vehicles. Stability control technology has been required by law in the United States in all cars manufactured after 2012, but VSC specifically is only found in select models.
The goal of a VSC system is to prevent skidding or loss of control in certain scenarios. When working properly, a VSC system will detect if your vehicle is slipping or losing traction and kick in to help you regain control.
How a VSC System Works
Typically, a car with VSC has sensors on all four of its wheels. Those sensors communicate directly with a module that sends signals to both your car’s engine and transmission. The engine and transmission then adjust based on those signals, optimizing performance based on the specific road conditions.
Why Is My VSC Light On?
Most of the time, the VSC light will flash on whenever the stability control system kicks in. This is an indicator that everything is working properly. But if your VSC light comes on and stays on, it’s likely indicating a larger problem. Typically, if something is wrong, the VSC light will turn on along with another warning light, like a Check Engine indicator. If this happens, you can use a diagnostic tool to read the fault code stored in your vehicle’s engine control module.
