Does anyone know how to "completely" delete/overide/de-activate the traction control system on an 05 Z51 manuel ?? What do the track guys mess with??

 

From the 06 owners manual. I assume the 05 is the same?

To turn the system off,
press the ACTIVE
HANDLING button on the
console for five seconds.
You can turn the
system on at any time by
pressing the button.
The DIC will display the
appropriate message when
you push the button.

 

Works whether it's a Manuel or a Ricardo.

 

Not trying to hijack but my tc will not turn off period! Idk what is wrong w it

 

It may say "active handling off" but if you really drive the car it is still there. I would like to know what the track/club racers do to bypass this feature.

 

Hop on a scan tool and see if the button is actuating

 

Do I have to go to the dealership?

 

Actually, it is off. Off does mean off. I really drive my car hard and know it is off. If I leave it on it really doesn't interfere but I can tell when it activates on certain turns.

Do all of your tires read the correct pressure? If any of them say your tire(s) are low, the display will continue to read: Service Traction Control System.

 

I used a friends "Autotel" scan tool that did as much as a Tech2

 

If the car senses any problem with any of the components that work the TC, AH, ABS, or tire pressure; it tends to keep the nannies engaged despite what you select with the switch.

 

Ahhh, I've got 3 TPMS inop! So that's whats causing the TC to activate under hard cornering? I want to delete the whole system like if I was building a track only car.

 

It is easier to fix the sensors than to fool around trying to defeat the system. Some track people install four sensors in a plastic pipe, pressurize it to 30 psi, train the car to those four sensors and then throw the pipe in the rear cubby so the car reads those sensors all the time. By the way Bob at House of Wheels sells genuine GM sensors for about $50 plus shipping.

For what its worth, there used to be a little black box called "LAPTRAX",(spelling ?).

It simply interfaced between the footwell computer and the AH/TC switch on you console. It could be setup up to any variant you wanted as the default. The only "problem" was it mimicked holding the button down, therefore when you started the car, it took a few seconds to follow the routine.


It worked great, cost was $119, I dont know if the developer still exists but I found him through the C5 forum a few years ago,(I am sorry I let the box go with the car when I sold it).

I just did a qwik search and found my post from 2011.

In July of 2011 he said "As a matter of fact, we do still a few available. $139.99 shipped. If you have any questions just let us know, thanks!". I would contact him. That post also mentioned a box called ATI Track Mem so there appear to be a few choices. Good luck.

I have to say IMHO, I keep the AH/TC on. The only time I ever got end for end was with AH off.

 

First of all, the problem you're having is with the AH, not the TC.

Pretty much can't get rid of AH, unless you really do turn it into a track car and go with a whole new ECM system, such as an MSD - but even then you might run into problems complying with class requirements that might require stock ignition/ECM/PCM.

That's also going to probably require that you go with some manual latches for the doors, a net where the windows go, and pins to hold your hatch down, because you'll probably lose all interface with the BCM and RCDLR. Butt.....if it's a race car that's what you want anyway!!

There was a forum member (GTPprix) who allegedly could reprogram the BCM to remove the TPMS, but a couple members in the AutoX/Roadrace section had him do his magic, but I don't think they got the results they were hoping for.

So.....the TPMS is a system that you'll have to deal with. It's a fantastic system and the best thing to do is to just make sure your sensors are in good shape and properly programmed into your TPMS memory. Most of us that track the car have sensors in all our track tires/wheels so we don't have problems with the AH going wacky during a track session, plus it's an excellent thing to have your tire pressures available, or especially alerts if you start losing pressure in a tire during a track session.

Starting with the 2008 model year sensors and a TPMS have been required in all cars by the Feds. So....it's like seat belts and airbags - a required system that can't be disabled or turned off.

It's a great system. Just program your sensor into your TPMS and you'll have a fully functioning AH system.

Hmmmmm.....I don't think that unit will come close to working in a C6!!!!

As mentioned in the post above, the C6 is required by the Feds to have a TPMS, and it legally cannot be disabled on a street car.

The TPMS in a C5 could be deactivated with a Tech 2 (at least the later model years when the C5 Z06 came out).

Tire pressure sensors and a TPMS are a MUST HAVE when running on runflat tires - you just don't get any handling feedback if driving straight down the highway. You wouldn't know you lost pressure until you took the off ramp in your normal spirited style and ended up in the guard rail when a sideload built up during cornering and you lost control.

The C5 Z06 came out without runflats, and the TPMS was deactivated. If you later put on runflats you could have the dealership turn on the TPMS with a Tech 2, or you could have it deactivated on other models than the Z06.

The C6 falls into the mandatory TPMS requirement area (certain percentages of each manufacturer's fleet had to meet the requirement for several years before the 2008 model year when 100% compliance was required, and since the beginning of the C6 in 2005 it was used to meet that requirement).

So......there's no way to disable/deactivate/turn off/or otherwise defeat the TPMS in the C6 without doing something like I mention in my post above - and nobody is going to to do that to a street car for you due to liability issues.

Wow, thanks guys great info for a newbie . I'm used to European cars companies that usually do strange improvements for the American market. I replaced both rear TPM's b/c the batteries were toast. Do you need to "learn" with the Tech2 or do they automatically get recognized ?
