What does it mean when a Buick car displays TC?

[MalachiLee]

When a Buick car displays TC, it indicates a malfunction in the Traction Control System. In this case, you should visit a Buick 4S store to have a repair technician read the fault code, identify the cause and location of the fault, and proceed with immediate repairs. The Traction Control System is a driving assistance system in vehicles that manages the power on the drive wheels. This system activates only when the drive wheels slip. If the drive wheels slip, the Traction Control System will limit the engine's power output and apply braking to the slipping drive wheels, preventing excessive slippage. When the Traction Control System is active, the TC light on the dashboard will blink; otherwise, it remains off. Buick is an automobile brand marketed by General Motors in the United States, Canada, and China. The Buick lineup includes several well-known models such as Excelle, Verano, Regal, Envision, Encore, Encore GX, Enclave, GL6, and GL8 Land Business Class.
