What does the TC warning light in a car mean?
1 Answers
The TC warning light in a car refers to the Traction Control System malfunction indicator. The Traction Control System, also known as the Track Control System, relies on electronic sensors to detect when the driven wheels' speed is lower than that of the driving wheels. It then sends signals to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or apply brakes to prevent wheel slippage. The Traction Control System not only enhances driving stability but also improves acceleration and climbing ability. At high speeds, cars are prone to wheel slippage, and if the driving wheels slip, it can even lead to loss of vehicle control. When this system is active, the ECU adjusts based on the current speed to enhance stability and acceleration performance. Additionally, during uphill climbs, excessive braking force can make it difficult for the vehicle to move. With this system, the ECU increases traction based on the current conditions, ensuring smooth progress. Reasons for the TC warning light to illuminate include solenoid valve failure, clogged solenoid valve filters due to dirty oil, wear and tear on actuator gears and impellers leading to oil pressure leaks and triggering alarms, dirty throttle with an opening reaching 20%, and the engine computer misjudging a TC fault, among others.
