fix the fan situation then re eval. Fans should not come on until 205* coolant temp with a/c off. If they are on before, there is a problem. The short could be draining the hell out f your battry and then the code pops up since the system cannot keep up according to the ECM/BCM

Sounds electronic in nature. My first guess is the regulator electronics in the alternator (it's all integrated in one unit). Did the alternator ever get tested an an elevated temperature? It sounds like the regulator circuits are starting to fail at higher temperatures. Testing on the bench at room temperature would not necessarily show this type of failure.
Just my 2 cents....

That's not bad compared to what the stealership is going to try to get me for since it's not something the pats/toy stores don't carry.
