I had my brakes serviced and when I left the shop I noticed the abs and traction control lights were on and have stayed on sinse . How can I make them go out ??

It might be the traction sensor on the wheels that send the signal it better if you bring the car back to the shop and have them double check the sensors
It sounds to me like you may have a bad speed sensor which on GM is in with the abs sensor in the bearing hub. Hope this helps
