What does the TC light on the car dashboard mean?

[VanBrandon]

When the TC light appears on the car dashboard, it refers to the Traction Control System. When the ABS (Anti-lock Braking System) detects that some wheels are slipping, it will apply braking to the slipping wheels to prevent loss of traction on those wheels. The full English name of TC is Traction Control System, which is translated into Chinese as the Anti-slip Tracking Control System. The purpose of the TC system is to maintain the vehicle's trajectory to match the driver's control. The traction control system relies on electronic sensors to detect when the driven wheels are rotating slower than the driving wheels, and then sends a signal to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or brake the wheels to prevent wheel slip.
