H3 4x4 Buttons

[Halibrand]

Ive got an 06 H3 with Adv. Pkg. and have been baffled by my 4x4 buttons.

Full time 4x4, so you have these three buttons: 4x4HI, 4x4HI(Locked),& 4x4LO (Locked).

So why is there an additional differential lock button?

( looks like this: I---X---I )

I cannot find any information in the manual about what it does and why its there. Help me out.

[Bebe]

Great question.

The H3 is Fulltime 4 wheel drive, and with all the newest and latest technolgy.

4HI - when in this mode the power to the axles is split 40 front 60 rear

4Hi Lock - in this mode the power to the axles is split 50 front 50 rear

4Lo Lock - in this mode the power to the axles is split 50 front 50 rear

The rear e-locker will ONLY engage in Low Range

Traction Control System is always on, either in high or low range.

Stabilitrac can be turned off manually or, when you put the transfer case into low range, you will notice the stab sysoff on the driver information center.

[Halibrand]

Ah. So when I shift into 4LO, it will automatically lock? Or will I have to push the lock button ( |---X---| ) to get it to lock once in 4LO?

Also, what is the difference between Traction Control & the Stabilitrak?

Thanks for your help, Bebe!!!

[Bebe]

Use the little x button to lock the rear diff once it is in low range, or 4 lo Lock.

You should not be moving when pressing the button, or no more than 2 MPH.

Intruction on turning off Stabilitrac is in your manual.

The description of Stabilitrac and Traction Control (TCS) are also in your manual. :D

[Bebe]

Ok, I forgot I had written this...

Stabilitrac:
A system which stabilizes the traction of the vehicle. It was designed to help prevent rollovers and driver error in emergency manuvers.

ABS:
Automatic Braking System...self explanatory

ETC or Electronic Traction Control: sometimes referred to as TCS
A system which recognizes a wheel with out traction thereby transferring the power to the wheel that is not spinning allowing the new "powered" wheel to move.

In deep sand if you spin the tires the only direction you will go is down. If you can back up/out then do so. Same approach applies to deep mud, the only direction you will be going in deeper in the mud. Only momentum is your friend.

However, in soil, (dirt without rocks) as long as you allow the free wheel or wheels to spin the ETC will transfer power to those wheels the are not spinning.

In cases where the sudden traction or contact of a spinning wheel would cause damage, BTM prevents the spinning wheel from freely spinning. This way when it does finally make contact, you won't explode something in your driveline.

So to Recap:

Rock Crawling, Slickrock or other such hard surfaces = BTM (Brake Throttle Modulation)

Loose soil, Dirt, Shallow Sand = Electronic Traction Control

Deep Sand, Deep Mud = Momentum

Snow, Ice, Rain soaked Streets = Stabilitrac

You cannot turn off the ETC, or ABS. You can turn off Stabilitrac.

If you have a Manual transmission, you do NOT have Stabilitrac.If you have the button, the car with squiggly lines underneath it, most likely, it is non operational. Only the Automatic Transmissions come with Stabilitrac.

Is this thread for real?

its antilock not automatic:flipoff2:

This is Pirate. Tell him to do a search or read his manual.

I didn't go to Slickrock because I had to go to work.

Are you looking to bump me off and take my job??:flipoff2:

When we get enough threads on here for an FAQ, then I'll tell him to read the FAQ or search or read the manual.

This is pirate, but its more so HUMMER Tech....not chit chat.

We are in "welcome" mode right now :D

If you ask a tech question, you get a tech answer, and yes I fawked up on the Anti lock Brake System, I don't know what made me type that.

We might be hitting slick rock on Fathers Day, you are welcome to join us.

x2

If you ask a tech question, you get a tech answer,


There was a time when someone (H8Monday I believe) said something along the lines of "Pirate4x4 is college-level tech, if you have a grade school level tech question take it somewhere else." This isn't (wasn't) a learner site for complete novices to come get their feet wet. Pandering to people who don't know the difference between a locked transfer case and a locked differential will ultimately bring the tech value of the entire site down.

[Bebe]

Apparently you need to read THIS forums rules.

Hummer Discussion guidelines:
This forum has been created for Hummers to ask questions and share information. It is not about being hardcore. Our goal is to keep this forum focused on Hummer tech, and have somewhere for Hummer people new and old to the sport to share experiences and tech.

If you have nothing positive to add to Hummer tech, your ass is GONE. If you don't want to help people with their questions, don't visit this forum.

[Indyguy]

No, I did not read that until now. I stand by my opinion; but I'll be sure to keep it out of the Hummer forum in the future. I guess Non Urban apparently being someone you're familiar with would explain why you aren't trying to get all authoritarian about his two replies that "add nothing positive to Hummer tech." You all enjoy your new forum. Hopefully in time there will be some cool builds popping up.

I explained it nicely once and you still popped off. Thanks for visiting the HUMMER Tech forum :flipoff2:

Didn't know you were the one to supersede rules around here. :shaking:

[DURAtotheMAX]

we were ALL newbies at one point. give the dude a break seriously

The difference is I didn't keep running my mouth.:flipoff2:

[GotSandH3]

I have a manual and a Stabilitrac button.... Are you saying I still dont have Stabilitrac? Whats the point of the button then?

[TJVigilante]

To fill in the hole, that's my guess.

From the H3 Manual which can be found here:

http://www.hummeranswers.com/files/hum_h3_2006_man.pdf

StabiliTrak® System (Automatic
Transmission)
Your vehicle may be equipped with a vehicle stability
enhancement system called StabiliTrak®. It is an
advanced computer controlled system that assists you
with directional control of the vehicle in difficult
driving conditions.

StabiliTrak® activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak®
selectively applies braking pressure at any one of
the vehicle’s brakes to assist the driver with keeping the
vehicle on the intended path.

When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle.

If there is a problem detected with StabiliTrak®, a
SERVICE STAB SYS message will be displayed on the
Driver Information Center (DIC). See DIC Warnings
and Messages on page 3-44 for more information.
When this message is displayed, the system is
not operational. Adjust your driving accordingly.
StabiliTrak® comes on automatically whenever you start
your vehicle. However, when the transfer case is
placed in Four-Wheel-Low Lock mode, StabiliTrak® is
automatically disabled. See All-Wheel Drive on
page 2-22 for more information.

To help assist you with
directional control of the vehicle, you should always
leave the system on. You can turn StabiliTrak® off if you
ever need to using the TC (traction control) on/off
button. If you press and hold the TC button for
five seconds, the StabiliTrak® system and the traction
control system will turn off. When this is done, the STAB
SYS OFF message will be displayed on the DIC.

Press the TC button again to turn StabiliTrak® back on.
See Traction Control System (TCS) on page 4-9.
If your vehicle is in cruise control when the StabiliTrak®
activates, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may reengage the cruise control. See “
Cruise Control on page 3-11 for more information.

Same Manual:

Traction Control System or Electronic Traction Control:

Traction Control System (TCS)Your vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that any of the wheels are spinning or beginning to losetraction. When this happens, the system applies the
brakes to limit wheel spin and also reduces engine
power. You may feel or hear the system working, but
this is normal.

The Traction Control System may operate on dry roads
under some conditions. When this happens, you may
notice a reduction in acceleration or a pumping sound.
This is normal and doesn’t mean there’s a problem with
your vehicle. Examples of these conditions include hard
acceleration in a turn, an abrupt upshift or downshift of
the transmission or driving on rough roads.

If your vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control. See
Cruise Control on page 3-11.

If your vehicle has a Driver information Center (DIC), a
TRACTION FAILED message will appear when a
Traction Control System or Anti-Lock Brake System
problem has been detected and the vehicle needs
service. See DIC Warnings and Messages on page 3-44
for more information.

When this message is on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.

To turn the system off, press and release the TCS button located on the
instrument panel.This light will come on steady when the traction
control system has been turned off. This light flashes when TCS
is active.


While the manual states clearly that both systems a turned off when the button in depressed, this is not the case. You cannot turn off the TCS System, even though it says you can in the Manual. Must have been a typo, or a general screw up.

[NEOCON1]

BTM will over ride the TCS

[samvoiceman]

lockers overide both!:p

[08H3]

2008 MT's also have Stabilitrak. I also heard, but can't confirm that it was on the later '07's.

[Shadow man]

The Stability Track appears to be the same thing as is the Active handling in the Corvettes. The Corvettes just have had it for years. I think since 97.

The Active handling in the Vette I will say has saved my ass a few times. It does work. I noticed in the H3 I can get it to activate on washboard roads while slinging it around and in the snow. It seems to work good in it too. It is more much intrusive in the Corvette though.

[BigKofJustice]

On the newbie question front, I'd rather see discussion even on entry level topics then none at all.

If pirate wants to pick up hummer tech posters it'll take a while. There are two extremely technical Hummer forum/sites out there, at least for the H1 so it'll take some time to build up.

If I recall there is a dummy / spacer button on the H3's, apparently for the upcoming front locker factory option with the next MY of trucks. I believe the 2009 H3T and H3's will have it as an option.

I'm thinking of getting lockers for my 1998 now and possibly upgraded steering after doing some crawling a week back. I'll see how much more rock crawling I do in the future before I decide on swapping outs differentials.
