What does the TC light on the Buick display mean?

[LeStella]

When the TC light appears on a Buick vehicle, it indicates a malfunction in the Traction Control System. In this case, you should visit a Buick 4S dealership to have a technician read the fault codes, identify the cause and location of the issue, and proceed with immediate repairs. The Traction Control System is a driving assistance feature in vehicles that helps manage the power delivered to the drive wheels. Here is an introduction to Buick's powertrain system: 1. The Traction Control System activates only when the drive wheels slip. If the drive wheels lose traction, the system limits engine power output and applies braking to the slipping wheels, preventing excessive wheel spin. 2. When the Traction Control System is active, the TC light on the dashboard will flash. The light remains off when the system is not in use. 3. 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 the Excelle, Verano, Regal, LaCrosse, Encore, Encore GX, Envision, Enclave, GL6, and GL8 Land Business Class.
