AWD on
I have a 2010 G37X. When I start the car everything is fine. Once it gets warmed up the awd light comes on and stays on. I don't even have to move the car and it comes on as soon as it gets warm. Thoughts?
Once it comes on the awd won't kick in if/when needed.

No codes given when I searched. But when I searched specifically under the ABS system it had a low voltage battery warning. I actually got a printout of that. Didn't really think much of that though. I'll find it and post

All of the wheel speed sensors are operating and all are reading the same speed as the vehicle is moving

A couple other things that I am noticing is my atf is 220° and engine coolant is at 218°. Not sure what normal operating temp is but that is above boiling point. Engine cooling fan seems to pretty much always be running once it first cycles on. It doesn't come on when car is cold though so it seems to be operating properly. Car is just never drops temp enough for fan to turn off

Your issue appears to be with the ABS controller (not the speed sensors themselves). Your AWD controller (module) has its own set of diagnostic codes that can trigger the light. The AWD system receives speed and brake signals from the ABS unit. If the ABS unit is not functioning fully, then AWD can't do its thing.
You either have a power or ground issue within the harness or connector(s). If you have a multimeter you can test for voltage and continuity at the ABS harness and go from there. The factory manual will detail which pins to probe.

I was parked when I took this image. The wheel speed sensors were all reading the same speed while stopped or moving. But this one, which I don't think is a abs wheel speed sensor was 18mph off from all the rest. I don't know where this sensor is though. There is a "v" that was cut off of the image. So it read "vhcl"
