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!

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.

hey guys, im going through the exact same thing with my 2004 pontiac grand prix. and i did my research and found a recall that described these issues. I contacted pontiac about this and they advised me to take the car to get a diagnois to make sure its a problem that relates to the recall and they will reimburse me the money it costed to get the dx and pay full cost for the problem. below im going to copy and paste all of the recall info. Hope this helps for all of us
 
Recall ID # 51199 - SERVICE BRAKES, HYDRAULIC
 
Hide Details
 
  
 
Recall Date:
  
JUN 23, 2004
  
Model Affected:
  
2004 Pontiac Grand Prix
  
Summary:
  
CERTAIN PASSENGER VEHICLES WERE PRODUCED WITH LOWER THAN SPECIFIED TORQUE ON BOTH FRONT BRAKE CALIPER TO STEERING KNUCKLE ATTACHMENT BOLTS. WITH IMPROPER TORQUE, THE CLAMP LOAD AT THE JOINT MAY NOT BE ADEQUATE TO PREVENT MOVEMENT BETWEEN THE CALIPER BRACKET AND KNUCKLE.
 
Consequences:
  
DEPENDING ON WHETHER ONE OR BOTH BOLTS BACKS OUT OR FRACTURES, THE RESULT CAN BE LOCKING OF THE AFFECTED WHEEL DURING BRAKING AND AN ABRUPT STEERING INPUT IN THE DIRECTION OF THE LOCKED WHEEL, REDUCED BRAKING AND NOISE FROM THE AFFECTED WHEEL, OR SEVERING OF A BRAKE HOSE, INCREASED BRAKE PEDAL TRAVEL, AND REDUCED STEERING CONTROL. REDUCED BRAKING OR STEERING CONTROL COULD CAUSE A CRASH.
 
Remedy:
  
DEALERS ARE TO TIGHTEN BOTH BOLTS TO THE SPECIFIED TORQUE. OWNER NOTIFICATION BEGAN ON JUNE 28, 2004. OWNERS SHOULD CONTACT CHEVROLET 1-800-630-2438 OR PONTIAC 1-800-620-7668.

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
