I am now confident the problem is my Traction Control module. The problem is that a new one is $1200 and a used one is still far to expensive for the car.

I found limited info on this problem in the forum. The advice seems to be to check the fuses and wiring to the sensors. I'll start there. I was told by a mechanic (not the dealer) that he could not get codes out of the module because it was not powering up.
