abs and trac off lights

one day the abs light came on and the trac off light came on without hitting the button. I have a 99 300 m with 90,000 miles. It would go off and on while driving but now stays on all the time, have any input. Any would be sufficient since i got ripped by the dealership before. Door locks both front, input and output sensors,window clamps both front window clamps broke.all in all nice car though

you have a problem w/ your ABS module which also is connected to your traction control. Might need a new controller.
