Hello guys, I bought that car with this light on. Why is this light on? What does it mean? How can I fix it?
Thank you for your help.

VSC stands for "Vehicle Stability Control." which is their version of traction control. So, most of the time it wheel be a wheel speed sensor and at the most the ABS controller, I would run the ABS codes to see which ones are stored, this guide can help:

Checked with scanner ABS, no problem. I drove the car and mechanic checked with scanner and found Yaw Rate Sensor not working, he calibrated it and now the light VSC is off.

Hmm, usually the sensor does not need to be recalibrated once in operation, it may have had a glitch, or the sensor is going bad, if the problem happens again plan on replacing the sensor. I am surprised there was no code for it. Thanks for letting us know :)
