For what it"s worth I have been chasing this annoying Service Traction System since I put a turbo on my 2003 ss in about 2006 or 2007.

I was told that it had to do with the fact that the engine was producing too much torque and the tranny freaks out.

It will go off by it self and leave me with the traction off indicator on.

I can shut the ignition off and when I start it back up it's fine.

Very annoying but I have gotten to where I just ignore it.

If I ever figure out how to make it go away you can rest assured that I will let the planet know about it.

take care,

What have you done for the tune on your turbo? Perhaps your torque management controls aren't correct.

That is a good possibility. When starting out I used DHP and a tune from CarTuning. Got the error.

Fooled around with the tune for a while and got it running better, but. I do not appear to have access to the torque management tables which I believe are

P0856 Traction Control Input Signal
P0857 Traction Control Input Signal Range/Performance
P0858 Traction Control Input Signal Low
P0859 Traction Control Input Signal High

That being the case I just sorta ignore it for right now.

Don't know what tuner program will hit those. HP? Tunercat?

Thanks for your input

HPTuners should allow you to access those tables.

Check out their forum and ask just to make sure. Mine is also DHP tuned

OK Thanks

Take Care
