Repeat “Electrical System Drain” alert after 12 V battery + full module re-flash

That is good info I’ll have to look into that. Thank you!

I wish mine were that easy.

I have nothing plugged in to the truck. I even disabled PAAK. Still continues to have parasitic draw. I'm thinking it's a faulty module or something that wont go to sleep. OBD Scanner shows around 5-6amp draw when everything is completely off.

If I go back to my truck after a few hours it disables the cabin lights when I open the doors.

Not sure what the deal is.

OBD2 dongle will keep modules on while poling them. This will cause significantly higher than normal draw since it won't shut down the modules normally and you won't get a true standby reading. If you have an OBD2 scanner, there is a parameter called Quiescent Ave. This shows the average milliampere draw from the 12v battery while the truck is in standby after the modules shut down. It should be in the 30mA-50mA range for normal vehicles.

Mine was at 72ma this morning when I checked the Quiescent Average

72ma would be about 5% SOC of a healthy 12v battery in a 24-hour period, so you should be able to go more than a week without battery messages if the truck is shutting down and staying in standby mode properly.
The other common issue is if the truck keeps getting woken up by keys, PAAK, door openings, Fordpass events, driveway shuffles, short drives etc., then the modules light up again. This can drain the 12v battery pretty quickly.
The OP may have a problem with a module that intermittently errors and doesn't shut down properly. Check your fault history with your OBD2.

It drains so fast though, certainly not 5%. And I bought a brand new battery (trying to fix the electrical drain warnings) directly from Ford. I'll have to figure out how to check the fault history, but that is good info thank you.
