No Idea Why!
Ok...leaving for work...dry, sunny day about 65 degrees, no wetness, dirt, or anything on the road.....doing approx 40-45mph in 5th gear......on comes the traction control....I was barely on the throttle, going in a straight line....no spinning or loss of traction occured....so I let it take its course...it took about 4-5 seconds to give me any power back.....then it did it again a few miles up the road...weird.... anyway here is what I have...
2000 FRC ...19's all around 245/35/19's up front and 275/30/19's out back...its dumped on stock bolts up front as low as I can get it...used longer bolts in the rear...it's pretty laid out...rides OK, seems to be no issues there....for info..Vararam and BB Bullets.....
IS/HAS ANYONE HAD ANY PROBLEMS LIKE THIS WITH THEIR C5?
if I hit the traction control button in the center console, or push in the clutch, everything comes back to life immediately..( I usually drive with the TC off 99% of the time anyway, but my Girlfriend drives it often and I'd just soon have the TC working properly for her safety)....just wish I could figure what was making it act up...
Does the TC work off of the ABS wheel sensors...maybe I have one on its way out...
seems like it only does it when Im in the higher gears 4,5, etc...could the clutch be slipping ever so slightly and the computer see it as wheelspin?, but that would throw out my wheel sensor theory....HELP!

Pull your codes!
This should give us a good idea as to what is making it act this way! (Hold your "Options" Button down and press the "FUEL" Button 4 times and it'll self diagnos)
Let it run it's course then scroll through each one and write down the codes and give'em to us and we can have better insight as to what is going on!
Theory: I think you might have a problem with one of the rear Sensers or as stated above it could also be a sterring senser going bad!
Why: Steering senser reads the steering and if or some reason it goes bad it will throw a code because it's not correlated with the rear sensers!
Example: A prolonged burnout will make a code set due to the fact that the rear wheels are turning and the front sensers are not or front wheels turned and the *** is pitching off to the side!
That's why it'll be necessary to find which code is being set according to the senser giving the command. (Plus it's possible ABS -I doubt that though - or could'a got wet in the senser some how!)
we'll theorize more later just pull those codes for now and let us know!
Thanks,Matt

Have you run this tire/wheel combination previously with TCS on with no problems? I haven't kept up with all the front/rear tire/wheel combinations compatible with TCS, but your front/rear tire stagger appears marginal
245/35/19 = 25.8 in. front diameter
275/30/19 = 25.5 in. rear diameter
If your tire/wheel combination has worked OK previously then I would
suspect an ABS sensor

as far as the wheel/tire combo...I just bought this car roughly 3 months ago.....put the wheels on it a few days later...been fine until about 2-3 weeks ago...but it doesn't do it all the time...seems like only in the morning on my way to work....I wash my car almost daily like it's my job...lol ...always do the wheels last ...waterblade the car and chamois it off...then back it back into the garage...could there be something wheel sensor wise that could be getting wet (never really drive the car in the rain unless I get caught by surprise).....the symptoms usually happen within the first few miles of my house...then disapear...never seems to happen on the way home after the car sits outside in the sunshine all day.....dont really know what to think...figured with as many people on this forum as Ive heard there are...that someone almost has to have had the same or similar problem....thanks...Nick

doesn't do it everyday....maybe once a week...sometimes 2 days in a row...but then nothing for a week or two...totally weird....maybe I need to keep track of when I wash it and see if there is a pattern to wash/traction control issues....

Your rear tires are too short.
A 275/35/19 would have been a wiser choice for the rear. I'm using 275/30/19s...but on the front.
Rule of thumb is keep the rear tires at least 1/2" taller than the fronts to avoid this issue. Yours being about the same dia all around, makes you very borderline, which is why sometimes you have probs, sometimes you don't. The faster you go, the more likely this intrusion will occur.
The traction control system works by simply comparing front and rear wheel speeds. When you alter tire size, you alter the reading of the wheel speed sensors. Sizing the rear too short (compared to the front), will simulate the effect of a rear tire spinning, and thus, traction control comes on and cuts power.
Also consider most people wear out the rear tires sooner...so if you started out with all new tires the same dia. and had no problems, but like to spin 'em up a lot..your rears will soon become shorter than the fronts, and then consequently, this becomes more and more problematic the worse the negative height difference becomes.
Bottom line is...for what tires you're running, this is expected behavior, and won't throw any codes. Either size the tires properly, or get into the habit of shutting TC off at startup.

Thanks guys...the tires are still pretty meaty, so looks like I'll be turning off the traction control for a little bit....or finding somewhere to enter a burnout contest in the near future...lol What size would you recommend...I wanted to go with a 20 inch rear but the Company I purchased the wheels from didn't carry the 20 incher....
I guess here is my other problem...the front wheels are only 8.5 inches wide......and the rears are only 9.5 inches wide.....what do you think I can fit on the rear...obviously I'd like to get a bit more tire under it but I dont want it to stick out and eventually sandblast the paint off my rear 1/4's......any suggestions? Thanks again guys, I appreciate all the replies

They claim that they don't have TCS issues with these sizes unless they are running on rough roads. They claim TCS does not activate when running on highways or smooth surface streets.

I think you hit it right on the head with the rough roads....good ol' Upstate NY...the road is a little choppy when I get the TC activation...Im sure being lowered a bunch and getting the bit rougher ride doesn't help much either.....no problems on the highway or smoother streets though....
