Author Topic: Mary Poppins Must Die -- Disabling Traction Control, ESC and Shutting Up OnStar  (Read 3250 times)

As noted in my other post reviewing my new OZs and Dunlop Direzza Z1 Star Specs, my 2007 GXP and I just finished 2 days of really hard autocrossing.  Great fun, but I need some advice.

Driving at the limit, several times, my car tried to "help" me in two really annoying ways.  First, even though I disabled traction control ('Traction Control Off') I think ESC was still on, because the computer would not let me apply throttle as I wanted to when the rear was sliding. 

Then I tried the hold down the button method, until I got both the TC off and ESC off DIC displays.  I could be wrong, but I'm pretty sure there was some residual ESC stuff going nonetheless. . . .

Second, and even more distressing, right after some really high lateral G turns, a husky, but slightly urgent sounding female voice emanated from the On Star rear view mirror. Things were busy in the cockpit at that moment, but I think I heard "Code [something or other]; dialing now."  I quickly touched the button to stop any calls to Central Command, and was rewarded with a "Thank You, hanging up" or something. 

Its odd because I do not subscribe to On Star, and really don't want my car ratting me out to "The Man" for tossing her around on the weekends.

I did not buy and prep this car to be nagged and "helped" by robo nanny devices.  I get enough of that from the missus. 

What is going on?  IS there an accelerometer somewhere I can put a bullet through?

Seriously, is there a way to shut all the traction and stability aids ALL the way off, for good, once and for all? 

And how do I banish Mary Poppins on her On Star minions from my car forever?  Clean my room?

I have no idea how to shut up the OnStar other than maybe a fuse, the traction control press once, traction off esc standard, press twice competition traction off esc increased, hold for 10 seconds everything off. Is what I have been told.

Lil goat...you are exactly right...the above methods work in the way he described.  OnStar must have sensed it was an accident, hence coming on...kinda relieving if you ask me...but I can see how it is annoying and distracting during a race.

My throttle induced slippage may have not been perfectly executed, but it was not an "accident."  Not yet anyway.   :D 

But I guess the On Star nanny bot sensed that I had lost control totally. 

Personally, I do not find it reassuring, but a little scary. 

What other data about my driving habits is being transmitted?  What is GM doing with it?

Would lining my helmet with tinfoil help any?

Hmm.  I always thought that OnStar worked by sensors that sensed a collision through impact or force.

No impact.  And it happened twice on both days.

It may detect ESC controlling the car, hold it down for 10 secs to turn it off completely and see if Mary squawks again!
