Not sure if Traction Controll is working?? - 5/7/2008 6:25:17 AM

Something I noticed this last time I managed to get myself stuck in some serious clay Mud.

I could only manage to get three wheels to turn two back and one front.

The one in the front was spinning but TC did not engage the other side even when "spinning" the tires? I am concerned that my traction controll is not working propely?

Any suggestions/Advice would be appretiated?

Did you try puting one foot on the brake while giving a bit of throttle just to see if it made any difference? They say you are not supposed to BTM an H3, but I was just wondering? I assume because you did not mention it the TC and/or StabiliTrack off was not displayed.

TC works by just applying brake to the moving wheel to try to shift power to the non-moving wheel on the opposite side, unfortunately it is not a
substitute for a locking differential.

It helps, but it is no locker.

Says who?

I do - especially if I don't have a rear locker - it allows more controled movement than the TC system (can be jerky) on some obstacles. That's more for rock crawling, though - not mud driving, I normally let the TC do its thing in the mud.

You have an 06 Manual.............different animal than T Rex. Literally...

I should have been more specific, they say you should not BTM an Auto Trans or any 2007/08 H3.

I can't remember where I saw that, and it was from two sources.

Should I dare to look at the 2007 manual????

Brake/Throtal Maniulation - basicly manual traction control. You use presure on the brake to stop wheels with less traction to get the other ones going.

Doc.... you have confused your hummer[space/no space]guys.

I did not try this technique called BTM? But will try it again under extreme conditions only if really needed ................ Good to know

I really need a front locker as this 4x4 is very heavy and it took three other 4x4's pulling together as well as digging to get me out as I was probably 4Tons of dead weight.

On the flip side however the extra weight really helps when you need to pull other's out of the mud

Traction control is an exceptionally lame way to do what HUMMER should have done in the first place and that is to install a locker in front. T/C is absolutely NO replacement for a locking diff! Good news is that they have wised up and are installing them in the 09's but pre-09 H3's are left out in the cold. Here's my beef with Traction Control for those who may not know how it works.

T/C works by sensing wheel slip in off road and slippery driving conditions. Example: If you're driving in the mud and the left front wheel starts spinning, T/C will apply brake to that wheel so the open differential will send power to the right front wheel because it has more traction. (In theory of course) This action will go on as long as the situation exists or the T/C burns up, whichever comes first. Now here's the beef. The very last thing you want in a deep mud hole is some stupid electronic device mashing the brake to one wheel when you need that wheel to be doing it's job!

Cue the lockers! A Locker, either Eaton, Detroit, ARB or ANY locker or limited slip diff is better than T/C. A locker doesn't need to sense squat and it doesn't need some cue from a CPU somewhere when to work. You push a button, throw a switch or activate it any number of ways depending on type and your two sides are locked up tight. Four wheel drive as God has intended it, all four corners doing their job without the aid of computers.

Keep in mind that if you have it in 4Low then the TC is automatically turned off. Also when I engage my rear locker it turns off the TC.

4low turns off stability control, not traction control.

Steve: Yes I did!

Sorry H G and HG.

My observation does still apply (if I was talking to HG, not H G ???), the 2006 manual does not have StabiliTrack, but does have TC.

Apparently, not only do I suffer from CRS, I also suffer from CRWITT...Can't Remember Who I'm Talking Too.

Eventually.......I will find where I did read
the "do not BTM an H3", not to say that I agree with the sources of where I read it, but I definitely saw it in print twice.

Remember though what some of the mechanics said last year that the Traction Control Off message is wrong when you go 4-low locked. I get the message all the time when I go there but since I have stick maybe it is turning it off for the manual's. We will probably never know.

There's not much to the system to "burn up" brake pads and ABS modules maybe. Traction control can also reduce engine power if it thinks it is needed.

What is better depends on the situation. Full mechanical lockers on a street driven vehicle can come in handy occasionally.... the rest of the time they are a nightmare. They eat up tires and can be noisy on corners or when coming in or out of the throttle, wet roads can put you in the ditch with no notice, you can only use them on rear axles, and your turning radius will suffer.

Limited Slip AKA Posi-Taction is a good compromise, not as strong, not 50% power to each wheel, but they also handle better and don't eat up tires like a locker.

Lockers and limited slips both "sense" different types of driveline forces of one or two different types.

Electronic traction control shines on pavement. Instead of sending you in to the ditch, it will keep you out of the ditch. Its downside is that sometimes it thinks it knows better when you're trying to have fun.

That CPU is monitoring many more points, and for over 95% of the driving I do, it's the way to go.

Selectable lockers are great, all the benefits of a locker and none of the negatives. Cross one with electronic traction control, and what could be better?..... right two... and that is the next step.

Gotta cede that to you Steve. Selectable lockers, ie...ARB or Eaton E-lockers are far superior to a detroit on the daily drive. I like the old Land Rover idea, manual cable locked diffs. Now there's an idea in simplicity, pull a lever, lock your diff. There's beauty in simplicity.

Again RealJeep I agree, what happened to good old lever 4WD and cable activated lockers?
