What does TC mean when displayed in the car?

[DelilahAnn]

When the TC indicator appears on the car's dashboard, it means the Traction Control system is active. TC stands for Traction Control System, which functions to prevent wheel slippage and potential loss of directional control when braking on slippery surfaces or during rapid acceleration from a stop. The Traction Control System relies on ABS anti-lock braking system electronic sensors. When it detects that the speed of the driven wheels is lower than that of the driving wheels (indicating wheel slippage), it sends feedback signals to the vehicle's system. The system then adjusts ignition timing, reduces throttle opening, decreases fuel supply, downshifts, or applies braking to the wheels to prevent slippage.
