Thanks everyone that responded. I was curious as to a wheel sensor possibly causing this as well as some other things. I guess what puzzles me is that the light doesn't come on at start up or later when the AWD doesn't engage and the AWD doesn't engage. I also read that if there was a problem in one of the modules, sensors, or motor that it would likely trigger the ABS light to come on as they are tied together but it hasn't . I wish I had found someone that had the exact problem but so far most that I have read include lights coming on and mostly AWD forever engaged which is the oposite of what I am experiencing .
