in my instruction book it says to basically kill power to the system and unplug communication cable ( little phone cord)
it should if its working go back to normal.
mine went crazy last summer when they changed out all four coach batteries and we had a FAIL message. the above corrected it and all has been ok since
we also found one of the 4 batteries was bad and it was causing the system to go charge crazy and ended up boiling the other three.
i would surmise you may be in need of four new batteries as well.
