Deactivating Traction Controll [B]COMPLETELY[/B]

[HumminNBoatin']

Okay so during the Grayling snow run I had a couple of hills that I wanted to run with some speed. However they had quiet a bit of big ruts in them making it a VERY rough ride to get up. Because of how rough the terrain was I did not want to use my front locker. I had TC2 engaged but and the brake pedal covered and I still could not completely defeat traction control from cutting power.

The TC2 was getting it done most of the way up but eventually it always interferes. I want to be able to flip a switch and completely disable it for those nasty, icy slippery uphill runs where you do not want to use a front locker.

Has anyone done this??? Or am I going to be the pioneer here?

I've heard that you can pull a fuse but I have never looked for the fuse or tried it. If there is a fuse and this method proves to work, there must be a circuit associated with it and therefore you can install a switch inline and manually turn it on/off.

Let me know what you find out

[HUMTECH]

You could remove etc fuse but you will also not have abs and it will set codes. Put the fuse back in and all would work again. Here is the wiring diagram if you wanted to put aswitch in that ckt

[HumminNBoatin']

Would this be a code that I could reset by just cycling the ignition 1 time? For example. If I have my lockers both engaged and I go over 20mph. I get a Service 4wd on the DIC. If I flip turn off my front locker and restart my truck the light goes away.

BTW.... I have my front locker set to only work with my rear. In essence they are tied together. And I completely understand why it throws codes when this happens.

[HUMTECH]

Yes. Once the fault is no longer present the codes will go into history and the light will go out. History codes clear after 50 ign cycles i believe but wont affect operation

Humtech thanks for the heads up!
I don't have my truck right now it?s currently at Rubberduck4x4. So I cant just go out and look into it.

Okay so I want to tap into this wire after the fuse. I am assuming the fuse for the ETC is located in the driver side dash fuse panel? Also can you tell me what color wire is coming out of the back of the panel?? And where it might run too? I would like to find a convenient place to splice a switch into that wire.

I am also thinking that I might try to pull the fuse and get into something sloppy and see how well the truck performs before I go through all the fuss of doing this.

HumminNBoatin', Looks like the fuse is under the hood.

what are you up to now Eric??? you're always up to something funny.... you silly silly offroading maniac.....haha

[HumminNBoatin']

uhh I dont like the location of that fuse. HMMMMMTECH! lol.. Can you tell me where this wire might enter the truck so I can spice it? I am really getting tired of putting holes in my fire wall plug/grommet thingy lol. I am guessing this wire can be found comming into the ecm in the center console?

[Easy Ed]

Eric, I will try to look through the SM and see if I can find a place inside the cab to get to the wire but, electrical crap is NOT my forte but I will look see for ya.

Eric, Don?t know if these will help but they are the best I can do.

If HUMTECH is saying to pull ETC/ECM fuse or splice into the circuit to accomplish what you are trying to do, it looks like the PINK 1339 wire goes to the Ignition 1 Voltage in cavity number 8 of the connector that goes to the EBCM which appears to be on the inside of the driver?s side frame rail. If this is all correct wouldn?t you want to splice the PINK 1339 wire in that harness, possibly some place easily accessible ?

Also, if you was to pull that fuse the manual shows that it also controls the Throttle Actuator Control (TAC) and I do not know what would happen then, hence why you might want to go straight to the pink wire coming off the cavity number 8 of the EBCM.

Hope this some where close to what you are trying to do and if anyone notices something not correct or has better info please speak up.

Good luck, Ed

P.S. Also sent to the e-mail address in your sig.

This is Great info. Thanx again..... Its going to be a couple weeks before I get around to actually doing this but here is what I am thinking of doing to test this theory

1. Pull the fuse and get on a loose surface thow it in low lock lock and see if I can spin them. However if that fuse completly powers the Thottle actuator the truck should not accelerate at all?? I guess there is only one way to find out....

2. Cut the pink wire and repeat test......

I hope to god this does not turn into a bomb and blow up in my face! lol

[Easy Ed]

Good luck and let us know how it goes, please

i believe you can also disable the TC with a tuner as well.

might have to select a huge tire size or something.. but it is another option

[mawinc]

Hello.I'm own a performance shop MAW Performance.We custom tune cars and trucks using LS edits.We have a dyno for WRHP results.We can turn down tc or disable it completely. But keep in mind there are other limits such as wheel hop and torque limit settings that will take away rwhp even when the motor puts out more.The computor will sense these symtoms and make adjustments to take away power.We ajust these in a custom tunning were as hyper tech /bully dog /diablo and many others do not.My last hummer h2 we tuned made 40 more wrhp.Pretty cool.Just a good reason for custom tunes,there worth it.
