    ABS and BRAKE lights come on at different times. Sometimes while driving. Most of the time after short hops to different stores etc. If I turn the engine on and off 3 or 4 times the lights will stay off for a day or two. I've been told the ABS control module is bad. Can not afford to get it fixed at this time.

    Abs light come on & dealer said the the abs brake module is bad. It may stay off during cold mornings but always comes on when outside temp is warm. Brakes still operate well. I will have to pump brakes if car begins to skid. Would replace if I could find module cheap.
