What does TCS displayed on the vehicle mean?

[VincentLynn]

When TCS is displayed on the vehicle, it indicates a malfunction in the Traction Control System. Here are the relevant details: When the Traction Control System malfunctions, a diagnostic scanner should be used to read the specific fault code, and repairs should be carried out based on the fault code's indication. TCS, also known as the Traction Control System or Track Control System, consists of the following components: ECM (Engine Control Module), TCM (Transmission Control Module), TCS computer, ABS computer, and wheel speed sensors. The working principle of TCS is as follows: it relies on electronic sensors to detect when the driven wheel speed is lower than that of the driving wheel. In such cases, it automatically adjusts ignition timing, reduces throttle opening, decreases throttle input, downshifts, or applies braking to the wheels to prevent wheel slip.
