What is TCS light?

TCS stands for Traction Control System. It is a feature found in modern cars that helps prevent the wheels from spinning out of control when accelerating. The TCS system works by adjusting the engine's power output and applying the brakes to the appropriate wheel to help maintain traction and limit wheel slippage. When the TCS light comes on, it indicates that there is an issue with the system and that it may not be functioning correctly.

Why is the TCS light on in my Hyundai Elantra?

The TCS light on your Hyundai Elantra may come on for a few different reasons. One common cause is a faulty wheel speed sensor. Each wheel on your car has a speed sensor that communicates with the TCS system to help regulate wheel speed. If one of these sensors fails, it can cause the TCS light to turn on. Another reason the TCS light may come on is due to a malfunction in the TCS control module. This is the component that controls the TCS system and may need to be replaced if it fails.
