2002 Chrysler PT Cruiser ABS light is on

I got into my car and hear I ding sound when I look down thinking its my seat belt. I see that my trac light has flip its self to off and my abs light is on. What could this be? I replace the belts yesterday and one of the pulley. Did I maybe do something wrong??

No, there is no connection between belts and the ABS Traction lights. You likely have a bad ABS sensor. Probably on one of the front wheels.
