Traction System Active - Daily
Every morning I back out of my driveway, and as soon as I start moving forward the "Traction System Active" message pops up, I hear the traction control activate(buzzing), and the hesitant engine. Then it goes away and I am off to work(no problems again while driving). Then when I leave work, always the same situation, although I am not backing out of a driveway or anything(I always back into my parking spot at work when I arrive in the morning). Any ideas of what causes this. I would say it happens on 90% of my morning commutes, and 75% of my evening commutes home. The stealership recently repaired the TSB for the steering wheel Service Active Handling Problem. But this is a leftover problem that was happening before and after that TSB. Any help would be amazing. I read someone mentioned to clean the contacts on the ABS sensors, but I couldn't find a picture of where those were and didn't want to go unplugging a bunch of things at the wheels.

Are there any bumps that you cross when you are leaving home or work? If you are pulling forward across a bump (like where the street meets the driveway) and one wheel hits it before the other TC can activate since it will see a change in the instantaneous wheel speed at one rear wheel but not the other. A small dip that one rear wheel hits can also cause it to activate. The C6 isn't as intrusive as the early C5s. With my 97 I had to be careful pulling onto the highway from my work parking lot as I turned the left rear wheel would hit the crease where the highway met the driveway and it would immediately trigger traction control. If that is what is causing the issue there is no fix for it other than to avoid the situation.

Well yes I have the little gutter on my driveway when I leave in the morning... but nothing at work would cause this when I leave in the afternoons?? It is very annoying, but I may have to end up living with it.

By the way tire diameter changes can make a difference in when TC reacts. Are you running stock size tires or some other combination?

The only reason this doesnt make sense to me is that if I hit a small pothole in the road, or go over speed bumps the traction control doesnt activate, so why does it happen only soon after i start my car in the morning and afternoon. Still puzzling to me.

Stock sizes. The ones on the car when I purchased it were actual stock tires. I recently put on michelin pilot sports which match the factory sizes. But it was happening before and after those, so i am not blaming the tires.

Interesting... Thanks for the info. It doesnt bother me insanely because I dont get any effect from it while driving. Its only after my initial startup. So I guess its nothing to worry about. Thank you!

Well, this morning I tried the backing up a car length further idea. It worked. Although this could have been one of those mornings where my car didnt want to turn on traction control. LOL. So what does that mean if that does work?

Threads like these make me wonder how I can just disable the standard TCS and leave the more extreme version in place for safety....
I can't even get on it when turning left off a major road without the LURCH of TCS kicking in - and unfortunately I often forget to hit "the button" every time I start the car.

It does the same thing every morning and every afternoon, right after you start up. If you pull back into the same spot immediately and back up again, does it do it again?
If not, there's something about the state of the system at startup that's different.

Another thing that can cause the same issue is sterering wheel alignment. If the wheel alignment is not correct, you will have to rotate the steering wheel to the LEFT or RIGHT off center when the car is driving straight. The EBTCM thinks your trying to go left or right and makes small brake corrections to accomplish what it THINKS you want the car to do.
Is your steering wheel dead nuts straight "ZERO" when the car is going straight down a flat level straight road??? If its off to the left or right,, it could cause an issue.
