H3 Traction Control Problem

[redbird]

I am having a similar problem. Going down freeway at 60 mph the wheel locked up and slid to a stop. The wheel then freed up and drove home. A couple of test
drives confirm that the tcs light flashes from time to time for a few seconds. we hear a noise from underneath(while the light is on) but brakes have not locked up the wheel again. The noise is best described as a fast clicking sound like a
gear running across a pawl. (If you have ever had the rear wheels off the ground and tried to put the auto trans in park while the wheel was still spinning you know the sound I am describing). Any ideas?

yep here ya go , they fixed mine in 2 days , if you have to drive much and your abs and stabili light aren't staying on , you should pull the fuses . my lights stayed on and the truck had turned off both abs and stabili after they started freakin out .

bad sensors and maybe a chiped or busted tone-ring

Where are sensors and rings located on the H3?
On other vehicles I have seen the rings on rotors, outer CV joints
as well as enclosed in hub bearing assemblies.

Also, does the TCS get its information from only the wheel sensors
or is there another sensor that somehow senses skids, rollovers, etc
such as some sort of motion type sensor?

Thanks again

I talked to the dealer and they were not a lot of help. They told me that if there were no codes set then their scan tool would not help us. I have been driving around close to home, but nothing wrong is happening. Am afraid to turn my son loose in it. I hooked up a obdII code reader myself and it did not read any codes. I am 2 hours from the dealer and don't want to waste a trip if they cannot help me.

Well I thought I would give everyone an update. As mentioned earlier we had the problem, took it to the dealer and had them look at the truck. They cleaned a sensor and gave the truck back. We had it back for a day or two and the problem started again. We took the truck back for the 2nd time. We talked to the tech and the service rep, they kept the truck for 2-3 weeks trying to get the truck to duplicate the problem. It did it for the tech, they changed out a wheel sensor and kept the truck trying to duplicate the problem one more time (we actually allowed the tech to drive the truck to and from home every day, he would keep the tech II attached during driving and it never happened again after the new sensor).

This was all in January, now fast forward to today. After the first occurrence my wife has always been extra concerned that this does not happen again. The last few days the truck has made the clicking sound in a parking lot at real slow speeds, but now today as she was driving down an expressway in town the problem came back. The truck has now stopped it?s self several times today.

Looks like we will be back at the dealer ship tomorrow.

I cannot help thinking that the problem might be in transfer case somehow. The clicking noise preceded my lockup which was a total lockup of front wheels While
sliding to a stop, the vehicle stayed straight and maybe kinda under control. Maybe the reason it stopped straight was because the stabiltrak was actually doing its job. Anyone know if there is anything in transfer case or front axle
that could cause a lockup?

We we went to the dealer yesterday and resolved our problem. We traded the truck in and got a new 07 H3. The old truck is still messed up and who knows what the real issue trule was. The good news is we shouldn't have any further issues, So if someone is looking at a used H3 I would not suggest our old one (even though it had 17K miles).

I do have to say Hummer of Orlando were verry helpfull and worked on a good deal for the new truck. They are concerned with their customers.
