i didnt know the older trucks had a bms. i know they have one that shuts down the truck if the radio or lights are on too long, but nothing to actually monitor the battery as in depth as what we are finding out. and like you, have never reset anything. this is all new to me. i have never heard of this. hoping we get more infoI can't speak about any raptor after 2010, but I disconnect my battery lots because it just sits lately, I throw the battery cable back on and fire it up and let it run, never reset anything yet. Interesting learning about the newer ones though, everything is getting more complicated.
