That's great to be able to chargge and the cell's are fairly even in voltage.
It may be that the OBC 39 and P1A44 are somehow related to something that happened in the past, and for some reason don't want to clear. Just make sure the open ends for the A/C and Heater wires are wrapped with tape and nothing metal is showing that could touch the chassis. Take it for a drive and test if turtle is gone.
take a look at this thread, P1A44 seems related to A/C: viewtopic.php?f=22&t=4439
