What does 'TC' mean when displayed on a Buick sedan?

When 'TC' is displayed on a Buick car, it indicates a malfunction in the Traction Control System. In such cases, it is advisable to visit a Buick 4S dealership to have a technician read the fault codes, identify the cause and location of the fault, and proceed with immediate repairs. More information about the Traction Control System is as follows: 1. The Traction Control System is a driving assistance system in vehicles that controls the power to 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 apply brakes to the slipping drive wheels, thereby preventing excessive wheel slip.
I also encountered the TC light on the dashboard when driving a Buick before. This is actually the indicator for the Traction Control System. When you accelerate on slippery roads and the wheels start to spin, the system will automatically intervene, and the light will flash to indicate it's working to help stabilize the vehicle. If the light stays on continuously, it might indicate a fault or that the system has been manually turned off, such as due to a dirty wheel speed sensor or wiring issues. This shouldn’t be ignored, especially when driving in rain or snow. That time in winter, when the light came on while I was driving on the highway and I didn’t check it promptly, the car wobbled and nearly caused an accident. Later, a check at the 4S store revealed a blown fuse, which was replaced, and everything was fine. I recommend that new drivers pay attention to the system status, keep it enabled, and avoid turning it off randomly.
