Why is my traction control light on and the car system said service advance Trac

After I paid little over 1500. That they would have to put it back on the diagnostic machine they had it on twice I just didn't have anymore money to let them do it.

Keep in mind that all we can do is pretty much guess at it so here is my answer : I suspect there is a problem within the Antilock Brake System that is triggering the other issues .. Suggest having a full scan test performed which includes test drive so live data can be viewed on scanner screen to check ABS operations .. Most independent auto repair facilities will be able to do these test... This testing should find any faults that's present within any of the onboard modules... Regardless of what is suggested, this testing IS eventually going to have be performed to insure a successful repair! Good luck with it!
