H3 Traction Control Problem

[whaaaaT]

holding down the button only turns off the stability control not the traction control so that shouldnt help anyway.

After the first occurance my wife called onstar and they checked for codes and found nothing.

Probably no codes. Did you go to the dealer yet? If not, if you can hold off a day or two.
Check your PM, I have some information, that I cannot release on an open forum.

strange maybe something is wrong with mine too then. Cause that **** dont turn off. The stability turns off not the TC. I had problems with it at the beach. Sometimes it will prevent wheel spin and you dont go anywhere you just sit there twitching in the sand. And when you turn it off it says stability off but the TC stays on and even though the little light is glowing steady. It will blink when the TC is working. Someone else go try to turn theirs off. Cause mine definatley doesnt turn off. Someone go put your h3 on a hill of lose dirt and turn off the TC and see if that light blinks. The little car with the skid marks.

same here, when its turned off with the button, there is still something on because wheel spin is still being controlled.

Sounds a bit freaky, but an ABS sensor sounds plausible sending the system into confusion. On mine you can only knock off the Stability System the TC continues to work and usually helps keep you out of a bind......most of the time...

Hang on a minute - if you press and hold the button for the 3 secs or whatever it is, the DIC flashes with "STAB SYS OFF" right? (Auto trans I'm talking about...)

Now, at this point are BOTH the TC and Stabilitrak off, or only the Stabilitrack switched off?

I switch mine off all the time when we hit the desert otherwise it gets a bit annoying - 4 Hi Lock in soft sand - wheels spin and are slowed down etc... I have to say, it feels as though the TC is off, but the central diff working well to maybe give the impression of TC ???? Also, when STAB SYS OFF, I've had the car in powerslides in mud (I know, need to grow up ) - that ain't gonna happen with TC is it?

F5 - definitive answer please?

I have not had the the need to turn off either, but this is from a bulletin issued by Hummer for '06 model year vehicles:

"This message is to provide clarification to the function of Traction Control and StabiliTrak on the HUMMER H3. Information provided in the Owner's Manual on how to turn off these two features is somewhat conflicting. Automatic transmission-equipped vehicles have StabiliTrak, standard transmission vehicles do not. To turn off both Traction Control and StabiliTrak, the traction control button must be depressed and held for at least 5 seconds. On standard transmission vehicles, the traction control button need only be pressed and released to disable Traction Control."

As for the symptom. I have to check on something, but it could be a defective wheel speed sensor (since I doubt if you have installed stainless steel brake hoses), or the EBCM could be defective or the program scrampled. (I doubt a sensor, since it would react in forward as well as reverse and screw up ABS.)

Sounds like it's possessed! I had the stabilitrac kick in for the first time yesterday on an icy corner. It was a very weird experience. I can't say that I liked the vehicle taking control....but it was very brief and probably kept me out of trouble. I can't imagine what it would be like on dry pavement under normal conditions.

ABS sensor on one of the wheels is out and TC thinks it has wheel slippage
