Traction Control System
What does this mean on a Buick Regal?
When you see the traction control system illuminate on the dashboard of your Buick Regal, it is a direct warning from the vehicle's onboard computer. When flashing, it indicates the system is actively working to prevent wheel slip. If it stays on continuously, the system is disabled or faulty.
Common Causes for Buick Regal
Slippery road conditions (if flashing)
Faulty wheel speed sensor
TCS manually turned off
Steering angle sensor issue
What To Do Next
If flashing, drive carefully as roads are slippery. If solid, ensure the TCS button wasn't accidentally pressed. If it remains on, normal driving is fine but expect wheel slip in poor conditions.
