ESC Light: All About Electronic Stability Control


Electronic stability control (ESC) is a revolutionary technology in newer cars. It helps keep a vehicle on course and reduces the risk of accidents and collisions caused by oversteering or understeering.
What Is Electronic Stability Control?
Electronic Stability Control helps prevent a car from “spinning out” or “plowing out” due to a loss of road traction. If this happens, your car’s ESC light will appear on the dashboard. Spinning out, or oversteering, occurs when a driver takes a curve that's too sharp for the car's speed, causing them to lose control and cause the vehicle to spin uncontrollably. Comparatively, plowing out, or understeering, can occur when a driver enters a curve while accelerating or braking. In this situation, the front wheels lose traction after passing over ice, oil slicks, or other adverse road conditions, causing the driver to lose control. The driver must correct the understeering to avoid an accident or collision. ESC automatically applies brakes to individual wheels of your car, preventing your vehicle from spinning out or plowing out. The technology cannot increase road traction, but it helps you keep your vehicle under control during extreme maneuvers.What Is ESC in a Car?
Your car may have ESC, and you might not realize it. ESC kicks in so quickly that you won't feel the need to correct your steering while driving. Vehicles with ESC have speed sensors on each wheel. The technology ensures that individual wheels can brake as needed. In addition, ESC features a control unit that tracks your car’s steering wheel angle and rotation around your vehicle’s vertical axis. The control unit collects steering and rotation information so it knows the direction you’re traveling. The system may detect that your car is about to go in a different direction than indicated by the steering wheel. If it does, it automatically applies the brakes to the appropriate wheel. The result: you’re better equipped to maintain control of your car and avoid a spin-out or plow-out.What Does Electronic Stability Control Do?
ESC helps keep your car stable. It reduces the risk of losing control when you make sharp turns or perform emergency steering maneuvers.Benefits of Your Vehicle’s ESC
