What does TC mean when it appears on a Buick car?

Buick car displaying TC indicates a malfunction in the Traction Control System. In this case, you should visit a Buick 4S store to have a maintenance technician read the fault code, identify the cause and location of the fault, and proceed with immediate repairs. Below is more information about the Traction Control System: 1. The Traction Control System is a driving assistance system in a car that controls the power on the drive wheels. 2. The Traction Control System only activates when the drive wheels slip. If the drive wheels slip, the system will limit the engine's power output and also brake the slipping drive wheels to prevent excessive slippage. When the Traction Control System is in operation, the TC light on the dashboard will flash, and it will not illuminate when the system is inactive.
When the TC light comes on in my old Buick, I immediately think of the traction control system, which is responsible for preventing wheel slippage. If the light is flashing, it's usually normal on slippery surfaces like rainy or snowy days, as the system is helping you stay stable. But if it stays on continuously, the problem might be dirty wheel speed sensors, a short circuit in the wiring, or a faulty ABS module. For self-inspection, I would first try restarting the vehicle. If the light remains on, I would check the fuse box for any blown fuses. Then, I would use an OBD scanner to read the fault codes and identify the specific issue. Ignoring this problem increases driving risks, such as potential loss of control during turns, so it's important to visit a professional repair shop promptly if the light stays on. Regular maintenance, including cleaning the sensors, can prevent many issues.
