why does the abs, traction, and emergency break lights stay on in the car?

brake fluid is not low, the anti lock system is not working on the breaks but brakes regularly work all the fluids are not low.

when the abs is not on line, the traction control follows. when the abs is repaired, the trac system will go back on line.

the system needs to be checked for a failed part. most of the time it is a bad wheel speed sensor. you need someone to test the system and find the failed part.
