What does it mean when the TCS light is on?

[DiCalvin]

tcs light on indicates the working status of the vehicle's TCS (Traction Control System). When this indicator light is on, it means the TCS system has been turned off. The following is a related introduction to the traction control system: 1. Function: It determines whether the drive wheels are slipping based on the rotation speed of the drive wheels and the transmission wheels. When the former is greater than the latter, it suppresses the rotation speed of the drive wheels as an anti-slip control system. 2. Precautions: When TCS detects wheel slip, it first changes the engine ignition timing through the engine control computer, reduces engine torque output, or applies brakes to the slipping wheel to prevent further slipping. In cases of severe slipping, it further controls the engine fuel supply system. During TCS operation, the transmission maintains a higher gear. When the throttle is increased, it avoids sudden downshifting to prevent more severe slipping.
