What does the TC light on a Buick mean?
1 Answers
When the TC light appears on a Buick, 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. Additional information is as follows: 1. The traction control system is a driving assistance feature in vehicles that manages the power delivered to the drive wheels. This system activates only when the drive wheels slip. 2. If the drive wheels slip, the traction control system will limit the engine's power output and apply braking to the slipping drive wheels to prevent excessive wheel spin. 3. When the traction control system is active, the TC light on the dashboard will flash; it remains off when the system is not in use.
