I have a 2013 AWD Ford Edge SEL with 191xxx miles.  I was using it to jump start my 2017 Peterbilt 579(which this time was unsuccessful) for maybe about an hour or so.  The batteries were drained so I left it hooked up to try and recharge them enough to crank the truck over.  Well, as I stated earlier that didn't work.  When I was leaving in my Edge the *AWD disabled* message popped up and the car started idling funny.  I stopped and turned the vehicle off and let it sit there for a couple minuets.  Then it drove fine.  I drove it to a gas station for fuel which was about 2-3 miles away using the interstate to get there at about 60-65mph with no issue.  After I got fuel, I attempted to drive somewhere else, and the same message popped up again.  I pulled over turned it off, waited a few mins, restarted it and was able to drive it home which was about 3-5 miles on the interstate at 60mph with no issue.  I google the code and according to google it could be wiring/sensors, overheating of the AWD system or the usage of the spare tire, which, I am not using. There are also no leaks that I can see.  I personally feel like I overloaded the electrical system by leaving it hooked up to my truck for so long.  I also read in a ford forum the procedure for resetting the Battery Management System--BMS.  Would that be a potential fix to reset the electrical system? I drove the car the next day to where I park my truck with no problem getting there.  On the way home the code came on again and I performed the same procedure as before.  I have a BlueDriver Scan Tool, so I scanned the vehicle, but no codes came up.  I also have one more issue.  My carrier bearing is shot.  So, I'm wondering if that could cause an issue with the AWD system? TIA!!!!!
