So I've been driving on a bad filter head assembly for awhile now and it finally failed in the Florida sun had to walk very far but managed to get a replacement and install it, as I was working on it I was intensely overheating myself and couldn't resist the urge to run the batteries down by running the fan so the batteries completely dead and I know this is a bad idea because one of the batteries is very old, I had a way to jump it so I wasn't to worried so I got to jump it and to my joy it finally started, and then it turned off after a few seconds of running. I have a scan tool so I read a code that said lost communication to FICM and im pretty sure the code was U0105. Did I fry my FICM? or is this just the result of low batteries and blown fuses? I haven't checked fuses yet, the truck is like 12 miles from me and have to ride my bike thankfully nobody seems like they want to tow it away on me. Just trying to get a game plan if it doesn't want to start.
