The reasons for the traction control off indicator light to illuminate: 1. Fuel system malfunction causing reduced fuel injection: such as clogged fuel injectors, low fuel pressure, or impurities in the gasoline; 2. Inaccurate air measurement, resulting in a discrepancy between the detected intake air volume and the actual intake air volume: if the detected intake air volume is lower than the actual intake air volume, the PCM-calculated fuel injection volume will be less than the actual demand. The function of the traction control system is to enable the car to obtain optimal traction under various driving conditions. The control device of the traction control system is a computer, which detects the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if the computer detects an excessive speed difference between the drive wheels and non-drive wheels, it immediately determines that the driving force is too high and sends a command signal to reduce the engine's fuel supply and lower the driving force.
I've been driving for over a decade and have encountered the traction control light issue several times. The most common scenario is accidentally pressing that button with the skidding car icon, which turns it off. Sometimes items placed on the center console can accidentally press the button too. Another frequent cause is a dirty or faulty wheel speed sensor - if it can't detect wheel rotation speed, the system assumes there's a malfunction. Last time my light came on was after driving through mud after rain; washing the wheels fixed it. If the light stays on constantly, you need to check the ABS system since traction control and ABS are interconnected. Remember, never randomly pull fuses yourself - that can easily make things worse.
