Have you checked your wheel speed sensors and associated wiring?

It is your tire size causing the problem. You have to keep rear at least half inch larger outside diameter to avoid problems. You can always just switch the traction control off until you get the tire situation straight.

Your front and rear tires have the same diameter of 25.7".
Just curious as to why you're running 17" wheels in the back, unless they're for drag racing.

I missed this the first time. This would definitely do it.

Stock is 17 on the front and 18 on the back. A few people run 18 all around but have to be careful of the tire sizes. Remember it is the tire size that matters and not the wheel. I run 265\35\18 on the front and 305\30\19 rear. If you buy new wheels be sure you get the correct C5 backspacing.
