What does the TC light on the car dashboard mean?
1 Answers
When the TC light appears on the car dashboard, it indicates that the traction control system is either turned off or malfunctioning. TC stands for Traction Control, a system designed to enhance vehicle mobility. When the ABS (Anti-lock Braking System) detects wheel slippage, it applies brakes to the slipping wheel to prevent loss of traction. During operation, the yellow TC indicator on the dashboard will flash to alert the driver. The traction control system uses electronic sensors to detect when a driven wheel's speed is lower than the driving wheels. Upon detecting this, it sends signals to adjust ignition timing, reduce throttle opening, decrease acceleration, downshift, or apply wheel braking to prevent further slippage. This system significantly improves driving stability and climbing capability.
