Service 4wd 08 suburban

I have an 08 suburban z71 5.3 and it keeps throwing a c0374 she you try to use the 4wd. Up until 07 it was a bad wiring harness but in 08+ it means that the general system temperature is too high. But it will do it as soon as you start it and take off in the snow and it gets pressure put to it. If anyone has run into this before let me know what you did to fix it. I've searched it and couldn't find anything.

Has the transfer case fluid been changed within the last 50,000 miles? If not best to have it changed.
