95 z28 abs/traction control problem

On my z28 everytime i start it the abs/traction control lights come on and stay, indicating that i have no abs or traction. i'll turn it off and
start it a couple of more times and the lights still come on. every once in awhile they'll go off. anyone have any idea whats wrong? i'm hoping its a fix i can do myself. really dont want to take it to the dealer and get ripped off. thanks
