What does it mean when the TC light is on in the car?

[SanEvelyn]

When the TC light is displayed in the car, it indicates a malfunction in the traction control system. If the light comes on, immediate repair is necessary; otherwise, it may affect the vehicle's driving stability and safety. The traction control system, also known as the trace control system, is designed to address issues such as wheel slippage when braking on smooth surfaces, which can lead to loss of directional control, or when starting or accelerating rapidly, where the drive wheels may also slip. The traction control system relies on electronic sensors to detect when the driven wheels are moving slower than the drive wheels, at which point it sends a signal to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply the brakes to prevent wheel slippage.
