Why did this happen?
 

We had some decent snowfall preceded by ice here in Kansas so I decided to see how the traction was on the H2. On an empty stretch of road I did a 180? and my traction control and ABS lights came on and stayed on.

I put a code reader on and erased the code and it didn't return but I have to wonder, did I confuse the system or worse, mess something up?

I also had something similar happen in my '06. I was dorking around in some slimmy mud with a friend doing donuts and generally getting the Hummer as dirty as I could, when my ABS light came on and the truck started free-spinning the tires. It seemed like the traction control had completely shut off.

I did some more spinning and such, and later shut the truck off, which reset the ABS light, and the traction control and ABS seem to be working fine now.

I chalked it up to Hummer being smart enough to realize I was playing around and really didn't need the Traction control and ABS on, but I never really looked into it further.

BTW, it's been working fine for 6 weeks or so since then, so I don't think you'll have any problem in the near future.

Anyone else have this happen, and does anyone know why it happens?

What was the code; C0245 (usually the one)?
If so, yes, you have confused the system. Since the system is looking to see a wheel speed sensor signal different than the other three, and you happen to be on glare ice or another type of extremely slippery surface, the EBCM sees some strange signals and cannot determine which, if any, wheel sensor is bad. So, it warns you that it has shut down the ABS/Trac system.
Under normal slippage it won't do this, but sometimes when doing donuts, the wheels speed sensors are sending out some strange signals to the computer.

Re: Why did this happen?
 

ie - one tire going backwards while the other tires are spinning forwards

It's a safety feature. You obviously know if you were doing something "different" when it happened, the computer doesn't. All it knows is it was getting some screwy data from the wheels speed sensors and can't properly control the truck using the ABS/TCS so it shuts down to be safe

Re: Why did this happen?
 

Thanks for the replies guys, good to know it's normal behavior.

FWIW the next day on a slick road the "traction control active" message came on so it seemed to be working correctly.

Re: Why did this happen?
 

Ya thats probably it.......:giggling: Why would you want traction while your wheeling anyways.

Re: Why did this happen?
 

DEE DEE DEE! Is the McDonalds morning shift over already?:clapping:

Re: Why did this happen?
 

Wow, it must be early down south, maybe after you, ma, and sis get it on, you'll be awake enough to give me a new witty insult.

Re: Why did this happen?
 

It wasn't an insult, I was mildly excited you came back for more sorrowful ownage.

Do you want to discuss the importance of traction while wheeling?

Re: Why did this happen?
 

I wasn't wheeling... See:

"I was dorking around in some slimmy mud with a friend doing donuts and generally getting the Hummer as dirty as I could"

:jump:

Re: Why did this happen?
 

Id love to! I think that if you got a error code from doing donuts....something is wrong.

Re: Why did this happen?
 

Hence the reason for the thread.

Re: Why did this happen?
 

yes, but some of your superiors are saying that its normal. If that is normal behavior, i suppose it makes sense being a GM product. I've done many donuts in my new subaru, and its computer is smart enough to not shut down the traction control system and abs.

Re: Why did this happen?
 

Then let me ask you something Einstein...why dont you go to a Subaru board then??????

You stupid mother****ingtrollingbitchassprick. Oh, and welcome.:clapping:

Re: Why did this happen?
 

My superiors?:giggling:

Oh noes!:eek: We should have gotten a Subaru.:dancingbanana:

Re: Why did this happen?
 

Thanks for the compliments, I like this board, it gives me a god like feeling being with all you wheeling noobs.

Re: Why did this happen?
 

Then post some pics please of your superior wheeling.....we are waiting....

If not then shut your troll piehole you ****ing tard.

Re: Why did this happen?
 

I don't want to, there is no point. I just tried to help with this serious hummer defect, and you guys just jump all over me....:lame:

ok maybe one pic.....it actually balanced there with no straps on. :D

Re: Why did this happen?
 

i guess that means i get to keep my piehole open! WooT!!!!

Re: Why did this happen?
 

Actually asshat a troll can post a pic from any site. Thats what ****ing trolls do. You know what, just continue with your troll like ways please. I will welcome when one of the "Not so Nice" members get ahold of your bacon burger flipping ass. You = sad for coming to a Hummer site and talking of your Subaru the showing a pic of a HIGHLY modded jeep. You drive a schwinn dont you.
