    I've got a spare Dorman cable if anyone needs one. I paid $65.00 with taxes from Napa Canada. I'll let you have it for $50.00. I'm in Ontario.

    Thanks again Eddie. If it wasn't for the help I received on this board I would have had to take it to the dealer and probably had to replace 2 front wheel bearings and the Electronic Brake Module. This would have set me back between $800. and $1200. like many other people. I just don't understand why GM don't own up to this as it seems to be a very common problem with these model years. And I've even read somewhere that they redesigned the cable in 2007 or 2008. So, why would they redesign if there wasn't a problem? And I would think it's a huge safety issue as the brakes pulsate when the warning lights come on that could scare allot of nervous drivers.
    After speaking with GM customer service Canada and even stopping by the dealer explaining to them what I found on the net, they blow you off and tell you they can't go by what is said on the net and need to put it on the scope to check for codes. Even though I'm 100% sure I'm not the only one that has complained or had this problem they insist on doing things by the book and that would have meant replacing parts until they found the problem. I must say that this really rubs me the wrong way.
    I've been a loyal GM customer for the past 30 some odd years purchasing 13 new cars from them for me and my wife. This last one has been the longest I've kept a car as I retired 5 years ago and use to replace cars every 2 years. I'll be looking for a new car in the next little while and I don't think I will even go to a GM showroom. It will be my turn to blow them off. I might just follow that commercial you hear all the time. Have You Driven A Ford Lately?

    I don't blame you. I've had terrible experiences with them trying to get them to stand behind their product.
  • So I took my 04 GP through the carwash this morning on my way to work... About a mile down the road, my abs and traction control light came on. I'm guessing I've got a bad wire. Did a quick google search on the issue and found this thread... hoping your info helps!

    Hi - I've had the issue with ABS/Traction control light for almost 2 years now. I ran the gammet of fixing almost everything with my AWESOME mechanic who pretty much did most of the work for free because when he can't fix something first time it becomes his obsession (wish you all had a mechanic like mine.) I never took it to the dealer dealer because we all know they SUCK!). final diagnosis was bad ABS computer control module (not the bearings, the ABS sensor in the wheel, wiring harness or anything like that) - it's a $1200 part, so my mechanic unplugged the ABS fuse that plugs into the computer - you can run without ABS - you still have regular brakes and (in TX) you don't have to have ABS brakes to pass inspection. Just know that when you disconnect the ABS brake fuse into the computer, every time you turn the car on you will get all the beeps, bells and whistles on the digital display telling you to check the system. Your ABS, traction control and brake light will remain lit up on the dash which is really just an annoyance, not a safety issue. WILL NEVER BUY ANOTHER GM PROJECT AGAIN BECAUSE OF GM'S ATTITUDE.! Going back to Honda, once this car (which is paid for and has been great except for this one issue) finally bites the dirt (its an '04 GP). Good luck to all! :lemon:

    Did you find out what it was because me grand prix is doing the same thing
  • I'm having the same issue with my traction control and ABS lights going off. After taking it to my mechanic several times (and after he finally stopped looking at me like I was crazy) he finally found out it was a bad ABS module. To go through the dealership for the part is crazy...does anyone know of any reputable online dealers?

    I had the same problem on my daughter’s 2004 GTP. I read that the wheel sensors should have a resistance of 960 to 1040 ohms. I measured all four wheels and they were all about 1,100 to 1,120 ohms. I tried cleaning connectors, and even put four 1000 +/- 23 ohm resistors at the end of all four harnesses. I also cleaned the plug for the harness at the ABS ECM, and also the ABS power relay. None of this turned off the ABS warning message.

    I checked the voltage at the end of each harness connector to the wheel speed sensors with the ignition turned on. Three of them were at 4.8 volts, and the RF was varied between 2.1 and 3.6 volts. As I shook the harness next to the RF brake, that voltage at the connector would jump up and down. With the connector still disconnected from the wheel sensor, I probed the length harness with pins and a voltmeter. At the ABS ECM, the RF circuit was 4.8 volts like the other three wheel circuits. As I moved along the harness, it stayed at 4.8 volts until I got to within about a foot of the wheel sensor. Then it dropped off to the lower level I measured at the wheel connector.

    I eventually pulled the wires out of the harness guard, and cut open some of the shrink wrap around the wires. Even though the car had not been driven for 5 days, the wires were wet, and the inside of the shrink wrap was full of sand and salt. I think what had happened was that the dirt there eventually degraded the insulation on the wires and was allowing some current leakage that resulted in the voltage drop.

    I intended to rewire this part of the harness and replace the end connector. I couldn’t get a new connector at the auto parts stores, but three different stores and a Chevy dealer sold a relatively short section of the harness with a new connector. My conclusion is that this mode of failure must be common, or all of the auto parts stores and GM dealers would not be selling a replacement harness section.

    After wiring in the new section on the end of the RF wheel harness, the ABS warning light is no longer coming on.
  • On further examination of the failed harness, I found a break in one of the wires inside of the insulation a few inches from the connector. This is an area where the wire would be twisted every time the steering wheel would be turned. The only reason I can understand for the wire to have any voltage at all is because the two broken ends must have been touching. The copper wire was also black and corroded.

  • Hi I Have an 04 Grand Prix GT last 8 numbers of the VIN : 41367899. After a very cold night(i was at the mall and I parked the car outside) the Service the ABS and the Service the Traction messages appeared. After I shot down the car and restarted the messages disappeared. I had to do this multiple times during the last 2 winters. This only happening when it's cold(I'm in MI) and I do a sharp turn. Just this morning (it's cold again) the messages will not go away even if I restarted the car multiple times Please give me an idea what I can do, thanks

    1 of two things is going on. You either have a bad speed sensor which is built into the hub bearing assembly going out or you have a bad speed sensor cable. First thing first get the car scanned & find out which wheel it is. Once you know which wheel second get under there with the wheel removed & on a jack stand start wiggling the harness from where it plugs into the hub bearing as far as you can follow it. Turn the wheel back & forth & try to duplicate the light coming on while finding the cause. If you find the harness to be good I would change out the hub bearing assembly like $150 at Autozone & pretty simple to do. Good luck!
  • Thanks Eddie, I started up again this morning after it was sitting for an hour, now the Service Traction/Stability/ABS System light are not coming on.... what you think?

    Thanks

    I think if u want to get rid of this gremlin get it scanned & start checking the speed sensor harness from the suspect wheel.
  • I scanned it when it showed the errors, no error codes...
  • eddie71eddie71 Posts: 10
    U have to have a scanner capable of pulling ABS specific codes. Then go under the ABS section to retrieve the "ABS" code. It will show no codes if you are in the PCM- power train section.
  • To the ABS light needing a module. Go to CHEAP ABS. com they repair the module for 99.00 and guaranteed. I just had the same problem and my mechanic said it was 1200 to replace it. I looked on the internet for information and found their web-site. I got the module from my mechanic and sent it to them and they repaired it and it worked great. I have not had another problems with that.
  • I already got it fixed for $200, they replaced the whole module ... no more lights, the copper in the cable was visible and that was causing the intermittent lights... one thing is sure... I'm not gonna buy GM anymore...

    This doesn't happen all the time but when I go over a bump, or when it rains, or the wheels go over oil, and I begin to brake, the wheels lock, I get vibration from braking, and the car is still moving. I have to shift to low gear to come to a complete stop. The only indication that appears is the traction control engaging. Is there any one out there that has or come across this problem and if so, how did you fix it. Please advise.

    06 Pontiac Grand Prix GXP (V8)
    I'm having Abs/stability control/traction problems too. Plugged n My own diagnostics machine. And it came up right front speed sensor circuit malfunction. So I replaced the hub. And It did not work. Same thing I especially noticed it when I make right turns it'll come on or right When I start the car???
    If you come across any answers please let me know this is really irritating :(
  • 06 Pontiac Grand Prix gxp.
    Hooked up my Diagnostics machine,
    C0040- right front speed sensor circuit Malfunction.

    So I changed the right Hub (did Not work) same issue Especially when I make a right turn or when I start the car It will come on. ???
  • Replace the harness on that side. Can be had from Napa, Rock Auto, etc......Was like $25
  • Does it hook to the hub? And where does the other end connect to??
  • I took my 2004 Pontiac Grand Prix GTP into the local service station today. He asked if I gave anybody a jump recently. My son had borrowed my car while I was on a business trip so I called him & asked. Sure enough he did. So it was a bad ground on battery that caused the loss of communication from EBCM.
  • 04 Grand Prix GTP with same issues, ABS/TC lights come on while driving and grinding noises on a flat straight even road. Can a GM Customer Service personnel like Christina or anyone please Email me @ andy_2590@live.com

    Thank You.
  • Fixed mine it was a wiring harness And sensor that fell outta place. Took it to haydocy and they fixed it.
  • I have a 2005 Pontiac Grand Prix. About a month ago i started to notice it was driving louder...i thought it was my tires! Took it to the shop n the guy said my tires are fine etc well its been a few days n the Traction control light n the ABS light both came on n about the same time i noticed it is starting to make a kinda grinding noise when i turn....and ideas?? Please and thank u!
  • What is the repair for this issue? Can I just buy something at the parts store to make this repair or is it something I have to have done at a dealership? I just replaced my rotors and pads all the way around and the issue is still there.
  • I wish they'd done a recall on my year (1999). Same issue!
