Phil,
Excellent sleuthing, I suspect Nissan hesitates to lower the resistance / leakage test parameters due to safety concerns. I've been preheating in the AM (heater is on the "list" of offenders) without incident. The heater can draw 6 kWh and seems to me the A/C would be less so it has to be something other than just current draw. It is circuit sensitive, maybe noise, fly back, heat or current on that particular circuit that's knocking the IR detection out of range. Maybe all that circulating fluid through the pump and metal lines creates a static charge, add condensation and it finds it's way to the chassis then "POP" goes the P0AA6. Sounds like fun detective work doesn't it, I love a good challenge.
