Chevy Colorado and GMC Canyon ABS Fault Issues

My 2005 Colorado started to randomly display an ABS Fault error message. In addition, when applying the brakes even at slow speed on level dry pavement, the ABS system will randomly activate.

I have read some other posts about the locks, windows and battery also not working. My battery has been fine, my locks and key fob work. My passenger rear window won't go down though. You can hear it click when you use the main control on the driver's door but it doesn't move. Any thoughts on what the deal is with the ABS and why it activates randomly? Thanks.

  • My '05 GMC Canyon displayed that ABS Fault message for the first time this evening while driving in 6 inches of snow, and the ABS ceased to function. Great timing. Don't know the cause yet. Knowing GM, probably never will.
  • I have a 2004 colorado same problem. i have been dealing with it for about 2 yrs. had it checked out there is something wrong with the wheel speed sensor most likely in only 1 wheel. mine is the drivers front. something about the seal bad allowing dirt, water to set off this censor also could be a problem. hoping chevy will do a recall I have heard several complaints about this poblem. hope this helps u out

    Having the same issue with 2004 Colorado, took it to the dealer and they had front left wheel speed sensor replaced...picked it up, hour later the light was back on and problem still exists. Still dealing with them trying to get it fixed.
  • I have this same issue with my 2005 Colorado, (74,000 mi). Local Chevy dealer wanted $400 to fix it. I think they said it was wheel speed sensor?
    It hasen't happened to me in a couple of months though, so i'm not too woried about it yet. Hopefully GM issues a recall, but I'm not holding my breath.

  • My 2004 Colorado has been displaying ABS FAULT intermittently for over a year now. When it first happened I brought to the dealer and the LF Sensor was replaced. The FAULT was back in immediately. Returning it to the dealer, I was told that there was no memory of any faults, and the pulsing I was experiencing was due to warped rotors. They could not duplicate the ABS FAULT. Leaving frustrated, my goal was to drive it until the fault came in hard. A year later it is still intermittent. I recently had the rotors and pads replaced. I took it back to the dealer last week and talked to the general manager. He said he would arrange for a GM engineer to take a look at it and call me back by noon. I never got the call. On my Colorado, the ABS activates without applying brakes and then a few seconds later it chimes and the ABS light comes on and I read the ABS FAULT as it repeatedly scrolls. It usually happens after I have driven for about 5 miles, shut it down for 15 minutes and then re start it. ABS usually activates when pulling out of parking lot going at a speed of 5 to 10 MPH. I have had the ABS activate at 30 MPH once. I'm afraid that it will activate when I need an emergency stop and will result in going through the trunk of the vehicle in front of me. I have sent an email to GM customer service and have not received a response.

    I have had the same problem on 2005 Colorado 4X4. Cost about $1000 to repair drivers side sensor a little over a year ago. Started acting up on same side about two months ago. Truck is nearly paid for; bought new at Hubler in Bedford, IN. 95 S-10 is still going strong at 220K. No wonder Consumer Reportrs rates this truck so low. I don't want to have to spend a fortune to correct a problem that doesn't seem to go away

    My Chevy Colorado has had the ABS light go on and off for a while. Sometimes during the day I would apply the brake and it would engage at low speed. Today was coming back to the office after making a deposit and the ABS fault light came on and then started pumping the right brake all by it self. Have no idea why it is doing this but no I have to have the car towed the repair shop. I am going to report it to Chevy and see if they have recall.

    I also have the same problem on a '05 Colorado Crew 4x4 w/77K. I have to stop and re-start the truck, then that seems to correct the brake pedal vibration and ABS fault error.

    I have been having the same problem. No one knows how to fix it. The abs system activates on it's own and then I get the faults. Hope some one figures out how to fix it.

    Hello MW328,
    Are you having a GM dealership look at the concern? Because the dealership have our tech department they can contact if they are having a problem they cannot fix. Thank you,

  • My problem has been resolved after a year of erratic ABS activation. The LF sensor was replaced at the dealership a year ago. The next day I was back in with the same problem and was told that there were no memory codes of the fault and that the activation I was feeling was actually from warped rotors. I drove the Colorado for a year and decided to get my rotors replaced. The same problem was still in so I took it back to the dealership. With the help of GM customer service the LF hub and sensor was replaced. It has been two months now and the problem has not resurfaced. Although the same symptoms were displayed from the beginning, I was told by the Service Consultant that the mechanic that had replaced my rotors had damaged the hub and sensor.
  • I have had ABS issues for over a year. ABS issues on one side, both hubs have had to have been changed...I can go on and on. The poor quality of this vehicle is unbelievable. No wonder why this money pit of a vehicle is rated so poorly.

    Did you find out what caused the error? I have the same thing for my 2005 Colorado Z71. I had to replace my rotors with 65,000 miles. The error occured. I have replaced both hubs and the mechanic has replaced the sensor twice. I have been told it is not doing anything bad to my truck but I don't like getting the error. I have looked out on websites and this is the first place I get the help. I figured it was the computer. Can you help further. I would like to give the mechanic something to start with, and would like to know if it is covered under a recall. It has cost me over $1,000 so far......

    My error also goes away after I turn the engine off and restart....

    HELP..... :confuse:

    The ABS ERROR seems to be an error that not only I have had. Did anyone ever find out what caused the error? I have the same thing for my 2005 Colorado Z71.

    Hello Ivfrank,
    It is possible that you just need to reset the computer to get rid of the fault code. Try turning your vehicle on but don't start it, and press the gas pedal all the way to the floor three times quickly. See if that resets the computer. Has the vehicle been scanned for codes? Thank you,

    The Mechanic has reset the computer codes grom the diagnostic plug in. Again, if it acts up and I turn the car off and then restart, it seems to work fine. Any other Ideas? Thanks.
  • lvfranklvfrank Posts: 7
    The codes showed that the wheels were turning at different speeds. They have replaced both front hubs, the sensors twice, and the error still appears every once in awhile. That is what is so disturbing, that it does not happen all the time......HELP
  • gmcustsvcgmcustsvc Posts: 4,076
    Hello Ivfrank,
    I would just take it back to your mechanic and tell him that the codes are still going off and the resetting of the computer didn't clear the codes. Have him just reset the computer and go from there. Thank you,

    Hello Franky74,
    I apologize that you still have a concern on your vehicle. Did you talk to the dealership and let them know the concern is still present? Thank you,

    I'm recieving the same abs fault like and I can hear a noise coming from the abs hub and I took it to the dealership and the say they can not replicate the error and there are no codes in the computer my warrenty for this dealership runs out in 2 weeks and I need to find a way to replicate the error, it usually happens when I start the car every 3 or 4th interval and not shortly after you hear a humming coming from under the hood and then the brakes feel as if they can not grab anything then the fault like comes on please help someone
  • gmcustsvcgmcustsvc Posts: 4,076
    Hello Abb1014,
    I apologize that you are having a concern with your vehicle. What does the code say on the DIC? The dealership may be able to put a code reader in your vehicle so when the problem arises it can read the code. Thank you,

    I'm having the same problem with the left front wheel sensor. After driving 5 miles, the ABS motor will activate on that side, followed by the ABS light. I clears after shutting off and restaring. I used an ABS tool to pull the code, which confirms left front ABS sensor.

    This truck seems to have a legacy of electrical ground problems. I'm wondering if the problem could be the ground pack mounted to the fender. I had a problem with the blower motor harness, where the connectors melted. Turns out it was the second harness, based on a repair report. Turns out this harness runs to the driver side ground pack.

    It seems that all you hear about is resetting the computer, but still the intermittant ABS fault will return with no ryme or reason, and then if you pull over, turn the vehicle off, and start it again, the error goes away. I am tired of this error. The mechanic tells me that it is not hurting the brakes or my safety, but I have had both hubs replaced at my cost, and have had the sensors replaced twice--again at my cost. Does anyone have a new Idea or is it just reset the computer. Tired of this--- It seems that this error effects more than me, maybe GM and Chevy should look at Customer Service and suggest a recall......
