That's fine if tires are the issue, or throttle control but it seems like that's sorta the point of all this to me. My tires have 20k on them and outside of today, I'm not laying into the truck. If its wet I need to be careful or it will spin pulling out in traffic.
I've read many post and like my buddy's sierra, the trucks wont spin no matter what. Seems odd to me, that's the only reason I asked.

Thanks for all of your input.

What tires are they? Some tires are just terrible on anything but dry pavement.

And trucks are light in the back end anyway so naturally they will spin the rear tires easier if conditions are slick.

My 95 was really bad that way. Had to really watch it around turns if it was remotely slick out. The tires I had on there didn't help much either.

I have Hankook tires on the truck now. Pretty close to stock sizing if not exactly. I guess this is the bigger question, why does tire matter? Shouldn't the system be cutting power and braking regardless of tire or situation?

I don't want to beat a dead horse on this or be annoying forum guy. Apologies if this exchange is already there. Not my intention. I was hoping there was a logical explanation, but if there is not I can accept that too.

Thanks again for your time and info.

Does your truck have the TC switch? Does it do nothing when you turn it on or off?

 

[dRewville]

alot of the NNBS and newer ones have an issue with this.
even when TC and ST are disabled, youll still get the rear end clunking and making a bunch of noises if you're out spinning tires. its annoying.

As far as i know, 4WD was only way it turned all that off completely.

 

[Hburgrado]

It has the button and when pushed i get the triangle off light. If I hold it i get the message stabilitrak is off. I cant say for sure if the truck acts different or not. Ill try and launch it tonight or in the am on my way to work (on the bike today). For certain though, with the TC turned on my truck is all over the place on the steep, wet hill I mentioned earlier. My assumption is that it's doing nothing and not throwing a code for some reason.

The only reason This came up was my buddy was considering following this video and it dawned on me that my truck doesn't do what his and the guy in the video does. Im not looking to fix or replace anything. Im happy to go 4 auto when its real slick out. I find it very odd though that something like this can be so different across trucks though.

I'll be wiring in a switch to cut power to fuse 9 this weekend.

My previous Silverado was an 09 and it did not have this dreaded traction control/stabilitrac/automatic braking bullshit. My current silverado is a 2012 and it is equipped with it, and its terrible. I live in a snowy environment and on a long, private dirt road that has snow and ice all winter. I am also constantly pulling out of snow-covered parking lots, and the T/C/stabiilitrac/ automatic braking is downright scary in these situations. I need to be able to spin the tires sometimes to get momentum. Anyone who has driven in these conditions know that "disabling" the traction control and stabilitrac with the button on the dash (yes even holding it down for 8 seconds) doesn't ACTUALLY disable the entire system.

I finally pulled fuse 9 the other day and it was glorious! Finally the truck does what I want it to do, not what it wants me to do. The traction control, stabilitrac, automatic braking, and unfortunately also the ABS are fully disabled with fuse 9 removed.

I am not comfortable driving around 100% of the time in a vehicle where I have purposely bypassed the safety features, especially ABS. This would be a major liability if I get in any sort of an accident. So it wouldn't be practical to be hopping in out of the truck multiple times a day to pull and reinstall the fuse. Wiring in a switch will be perfect compromise- I can flip the systems off when needed and turn them right back on a moment later.

ETA: I don't mind that the vehicle is equipped with these systems, they actually work very well, and I will leave it on 99% of the time. I just wish they would let you turn it ALL THE WAY OFF if you wanted to. Not give you a button that makes you think you are turning it off, but actually not.

I agree 100% and wiring the switch is a great solution. I know it has been done before.

Here is a couple videos that might help you out in your mod.

 

[kevinfranklin]

So what's the conclusion as to what the button actually does? My '17 alerts me that I've "Activated" or "Deactivated" its ST, but now I have no idea what that actually means. I'll check my users manual, but I've grown accustomed to it not telling me the whole story regarding these types of details most folks never worry about.

 

[esox07]

In my experience, I don't think the buttons really do anything. It might limit the systems a little bit, but it certainly does not turn them off.

Exactly. My truck is a 2012. Even when the truck tells you the traction control and stabilitrac are off after holding the button down for 8 seconds or whatever, the truck still will not let you spin the wheels. It might give you a little more wheelspin but it is still heavily limited and can actually damage your transfer case if spun to much. The dynamic braking is still enabled and will still limit wheelspin and slide wihen the dash tells you traction control and stabilitrac are "off", this is even mentioned in the manual. The only way to really disable the entire system that I know of is to pull fuse 9 on my 2012. The problem is that is also the ABS fuse.

The truck just feels and sounds so much happier in the snow with fuse 9 pulled.

 

[19trax95]

On my 17 the buttons seem to shut them off fully for the most part. Except stabilitrac. It will shut off until around 40mph or so.

I shut them both off using the button and I'm able to spin around and do as I please as long as I don't go above 40ish mph. Then the stabilitrac comes back on by itself. But if I stay under that speed, the truck doesn't seem to hamper me doing some snow drifting in the work parking lot. Even did some doughnuts last night.

Having said that, I've found that the traction control will stay off when driving, and let the wheels spin. BUT, if I'm going along on a snowy road and goose the throttle to get sideways, the stabilitrac kicks in and kills power. But if I don't get it to go sideways or swing, it will just let the tires spin like crazy.

The gmt900 trucks I know are different since my father's old 09 wouldn't let the wheels spin regardless if the button was used to shut it off or not. Would spin for a second then the truck would kill all power. Even in 4hi, 4lo it would let them spin.

Watched that video a while ago and was interested, I just don't see the need for it...yet. But it is good to know..
On a cabin trip 4 hours from home I made a silly mistake of pulling over to let the dog relieve himself, I got a little too close to a ditch (that I didnt know was a ditch) and the truck slid right on in. I used 4LO and eventually got out.. here's a couple of pics.

And here's a picture of the cabin, the 15 minutes drive in..was all untouched snow.. but she still made it eventually oh and the morning was -35C -31f!

I considered doing the switch mod on the fuse box, but I figure if I ever have to disable it to get unstuck from somewhere, I can just go in and pull the ABS fuse and then put it back after I get out. It would be nice to be able to really control it from inside the cab to be able to "play" a little, but I figure pulling the fuse isn't that convenient when I really need it off.

Im in the same boat. I had though about trying to do some sorta mod where you use an add a fuse or something and wire a switch in to cut power when flipped, but IDK how to wire it and I dont want to risk damaging something. Same goes for doing the switch and wire, your cutting a part of the factory harness and if something goes wrong its not good. For now Ill just pull the fuse if I want to.

I will say that the 4wd and GOOD tires work well in the snow. We had 2 blizzards this year but no other real snow, I didnt have an issue and I mostly drove around in the automatic 4wd setting which seems to be some sorta AWD or something. I didnt really have an issue and only rarely slipped, then of course stabilitrak kicked on.

 

[nealinator]

Interesting thread. Following. I sure would have thought doing the long hold on TC and seeing the TC and SC turned off that they would in fact be off.

Lew told me to turn them off for the WOT run...and he saw lots of knock retard. Could this in any way be the TC/SC system working against a WOT run?

 

[esox07]

Yah, Neal, I wouldn't be surprised if it did.

Using 4WD isn't necessary most of the time that TC and stabilitrac kicks in. Its mostly pulling out of snowy driveways and snowy roads onto dry roads that it pisses me off the most. If I could just spin the wheels in 2WD it would be no issue. I don't want to put in 4WD to exit snowy parking lot, pull out into traffic in 4WD on a dry tar road, then let off the gas to shiftback to 2WD. Completely ridiculous.

There isn't much that can go wrong with splicing a switch in-line with one wire. It would be easy to revert if needed. I am not worried about that.

I've been researching this and its funny how many people say to read the manual when someone asks how to completely disable the TC and stabilitrac. You can tell who is just a fair-weather mall-hopper and who actually drives in adverse conditions.

 

[esox07]

motodeficient: If you check the one youtube link that I posted earlier, the guy explains exactly how to do the switch mod, so, yah, pretty straight forward and could be easily reverted back if necessary. I certainly wouldn't advise against doing it for someone with basic wiring knowledge with care taken while doing the mod.

We are supposed to get some nasty ice/snow sunday into monday, and I will be sooo happy to have my 4wd. When the snow plow comes by and piles 20" of packed snow at the foot of the driveway, I have no problem getting out....My wife and her Cobalt....well, that requires me suiting up and dragging out the damn snowblower before she can even think about backing out.

 

[Motodeficient]

Its done. And its awesome.
