The traction control light is on and will not go off, is there a problem? on 2003 Chrysler PT Cruiser

The light was on one other time, but it went off after a couple of days. This time, the traction control light has been on for more than 2 weeks. I noticed the steering wheel shuddering when I brake at higher speeds. I believe the light came on when I put the car in reverse and started backing up before releasing the brake. Is there a way for me to turn this light off? I just bought this car used, and it had no books.
