i think you have to do battery registration on these or it wont charge correctly also the intelligent battery sensor gives trouble. if there is no customer complaint referring to the said fault code it wouldn't worry me too much. what scan tool are you using? also its a good idea to keep the software up to date on these, out of date software can cause all sorts of issues.
