2013 BMS Info requested

[Virto]

Hey all -

I've recently purchased a 2013 SEL AWD.  I noticed after stopping on the way home from the dealer that the infotainment display stated low battery audio off.  I checked the battery with a carbon pile tester and verified the system was charging at idle and everything was fine, but the battery was very much the wrong group size and didn't even fit securely in the tray.  The dealer replaced it for me with a brand new battery of the correct size and the issue went away for a day.

 

Now, the message is back every time I turn the car off.  As best I can tell, there's nothing wrong with the battery whatsoever.  I even pulled it, trickle charged it and then reinstalled it.  I eventually found out that you need to reset the BMS when installing a battery and did this via Forscan.  The issue immediately went away but has since returned.

 

I will admit that it's wicked cold here in Chicago at the moment, but the thing always cranks very quickly and starts instantly.

 

At this point I'm simply interested to know if there's a way to permanently disable the BMS either via Forscan or possibly disconnecting the induction ring around the positive cable.  Does anyone have any experience with this?  It seems to be done fairly commonly on the F150s with start/stop.

Is there a way to rest the BMS manually without a program?  I have a 2013 Limited.

let the vehicle sit undisturbed for 8+ 2 hrs after engine shutoff and removal of any aftermarket devices from power points/depowering of devices that continue to consume battery power after ending shutoff.
