The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

    ABS light kept coming on. Mechanic changed the sensor, but the light remained on afterwards. Another mechanic replaced the first one (which was malfunctioning). ABS was still on. Upon slow stops, I could hear a slight noise and felt the brakes crunching as I came to a complete stop. We finally disconnected the ABX system. The light is still on, but the noise and crunching sensation are gone. I learned to drive with regular brakes, so I know how to apply mine without the ABS so I'll just use my old brake-knowledge from now on.

    I have very low mileage and my jimmy. Two warning lights lit on my dash, the ABS light and brake light have been on for a long time

    The problem is, the light won't go off, except once in a while, for a very short period, then it's back on! I have replaced the brake pads, and the rotors are fine. I have bled the brakes, and still the light will not turn off.

    I'd like to know what the solution is.

    ABS light goes on and breaks lock up and do not press in, I have to pump the break to get it unstuck. We have almost had a serious crash more then once. Had if fixed, one month latter it is doing it again.

    Had the ABS light come on so I googled it and checked under the hood. noticed fluid had leaked from control module. I got a replacement from a friend who's truck was about to be scrapped. Replacement was easy bleeding went without any problems.

    Tip you dont need a special tool to signal the module to perform it's bleed routine. Just find a stretch of road with slick gravel get a little speed and stand on the brakes. After a few times this will rid the module of air bubbles

    I Hcw no brake on rear driver side after replacing brakeline. we have bled and bled the lines, all are fine. when we take off the bleeders on the abs, it sounds like it is airbound. we sent the vehicle to a mechanic. the mechanic checked it out and said the abs module is not working. so we need a new module. Nothing shows up on the computer.
