He's right about a burning hate9/10 it’s the ipdm or ecm having an intermittent internal short, I’ve done this countless times.
Best course of action is to pull the ecm and send it out to be rebuilt, they will respond by saying it’s too far gone and sell you a new one that pre programmed to your vin.
I have a burning hate for Nissan because of these issues, hope it helps.
Am I the asshole everyone is waiting for?
