Has anyone pulled this code from OBD diagnostics readings? See above
are they talking about MEMORY 1 SWITCH located on driver door, used to set personal preferences?!

job 2 car-

had CHARGE FAULT show up this morning(fordpass) car was plugged in, orange ring at charge port,
disconnected, then white ring, car had charged to 95%

Around 7:40am
inside car- CAR TURNED ON, warning box came up for split seconds, something about 12 v battery issue, service soon…..
plugged in OBD dongle & started car scanner- initial 12v battery SOC showed 49%(reason for warning box!?),
once OBD dongle refreshed, showed 85%, charging at 14.5 v

observations-
7:55 am- 12v SOC 93%, still charging at 14.5v, if door opened, goes to 13.2v
CAR TURNED OFF- 12v, reading 12.4, door opened 12.3v, 12v SOC dropped to 89% over course of several minutes

update 9:18 am
Car on, OBD dongle & car scanner running- 12v SOC 74%, charging at 14.6v……in 2 minutes SOC has gone up to 78%…..
That’s where things stand….
I will leave car on, monitor 12v SOC, see that it stops charging around 95-96%, voltage & see how it drops…….
open door charge voltage drops to 13.2v……. 9:26 now at 86% SOC Bill Pitman

From my experience that 12v behavior is normal as far as voltage and SoC recovery. Don’t know about that DTC though.
