Yes, I had to disconnect the sensor wire. On this vehicle, the sensor wires go into the hub assembly. I installed the new hub assembly and plugged the wire back together. I was looking at it again this morning. I unplugged and plugged back in the wire a half dozen times and then applied some dielectric grease to the electrical connector, still the light will come back on in just a short distance of driving. Again, this morning I hooked back up the OBD II scanner. I got it to work however, there were no trouble codes stored. Another thing I did today is take the vehicle for a ride. At around 50 MPH, had the driver slam on the brakes as if a deer jumped out in front of her and the ABS braking system definitely is not working. There was no pulsing in the pedal. I also loosened the spindle nut and retorqued it to 140 ft. lbs. thinking that maybe it was to tight. This also did not resolve the problem. I will try your suggestion of pulling the ECM fuse If that doesn't do it, I will have her drive it for a day or so (she will have brakes, just not ABS brakes). If the lights are still on, I will try replacing the hub assembly with another one.

Did you in any way bump or disturb the track sensor while changing the hub assembly? With respect to your scan tool, each manufacturer is different in their particular method of reading failure codes. For example the manufacturer's manual might call for you to turn the key on&off several times to activate the test and scan mode. Another thing you might try is with the battery connected remove the ECM fuse for 5 minutes and see if that clears the code. This is kind of a hale Marry shot but you might try "alldata.com and see if they are giving any information away for free. I had kind of the same problem after installing a disk brake upgrade on an 04 Mustang. One ABS sensor ring inside the rotar hub was 0.010 smaller than the other three and it kept tripping the ABS warning light. That mother scratcher was a real party to find. Good luck guy.

Today I changed the front left hub assembly I.E. wheel bearing on a 2002 Buick Century. I wasn't sure which wheel bearing was bad so I jacked up the front of the car and blocked it so that both wheels were off the garage floor. I then had someone start the car and put it in drive, and accelerate to around 50 MPH . The left wheel was noisier than the right one, so I removed the old left side hub assembly containing the wheel bearing and replaced it with a new one. This did fix the wheel bearing noise, it is gone. However, now the TRAC OFF light on the dash is lit and stays on while the key is on and when the car is being driven down the road. How do I turn the light out? I double checked the wheel sensor and it is plugged in. I hooked up an OBD II scanner but for some reason it wouldn't communicate with the ECM so I couldn't pull any codes. I disconnected the positive cable from the battery for 10 minutes and reattached it. The light was out when I turned the key to the on position and stayed out when the car was started but came back on in 500 feet of travel down the street. The only thing I can think of to do is to try pulling the codes again. This OBD II code reader is fairly new to me. I only used it once before and that was on a 2000 F150 4x4. The truck had a miss. I plugged the scan tool into the port beneath the dash, turned the key to the on possession without starting the truck and then turned the scan tool on. The scan tool gave me a P0301 code. I changed the coil on plug and the miss was gone. When I plugged the scan tool into the Buick, I used the same procedure as for the F150 but for some reason, I got a message that the scanner could not communicate. Does anyone know if the procedure for pulling codes is different for a Ford verses a GM vehicle? Any and all ideas will be appreciated :) Thanks :) To listen to the show archives go to link http://acbradio.org/handyman.html or ftp://ftp.acbradio.org/acbradio-archives/handyman/ The Pod Cast address for the Blind Handy Man Show is. http://www.acbradio.org/news/xml/podcast.php?pgm=saturday The Pod Cast address for the Cooking In The Dark Show is. http://www.gcast.com/u/cookingindark/main.xml Visit The Blind Handy Man Files Page To Review Contributions >From Various List Members At The Following address: http://www.jaws-users.com/handyman/ Visit the new archives page at the following address http://www.mail-archive.com/[email protected]/ For a complete list of email commands pertaining to the Blind Handy Man list just send a blank message to: [EMAIL PROTECTED] Yahoo!
