GMC Jimmy ABS Light Due to Brake System Control Unit Failure

(39 reports)

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. -
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. -
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. -
the abs light stays on all the time that im driving -
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 -
Low pedal height. constant adjusting abs long stopping distance -
ABS light and brake light came on. Possible ABS control mod. Cost to replace is about a grand. Any other suggestions -
ABS Light Due to Brake System Control Unit Failure -
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. -
Having issues stopping at low speeds with fluttering at the end of my stops in which the pedal fights back, significantly increasing my stopping distance. -
Replaced abs unit with used one off ebay -
ABS light won't turn off very often, and when it does the ABS system crunches when you try to brake. Also gain distance in stopping power. SCARY! When it rains or snows the light sometimes goes off. When the light is off that's when I get the crunching in my brakes and then the "Boing" sound at or near the end of my stop. Afterwards the light usually comes back on. When the light is on I don't have any problem. When I do have a problem it's always at very low speeds. -
black tape over the light was my solution. I grew up with standard brakes so this does not effect my breaking. -
Jsut bought this used car. One week into it, ABS light came on. So my $3,000 purchase is now going to be $4,000. There's got to be a cheaper way...... -
ABS its went on, took vehicle to Tuffy Auto Care and they disabled the anti-lock braking system. Lite are still on occasionally but system no longer is supposed to be working. Was told no motor harm is/will be done by disabling the system. -
abs syas that i am on rough terrain even on freshly paved streets and will engage the abs system limiting my ability to stop properly. no solution yet -
