Best Answer

it means that the charging system voltage is too high, and that the

Battery voltage sense input is above target charging voltage during engine operation. which can also occur when you are charging your battery during operation, it has happened to me, if that be the case then its not serious, just unplug your battery for a few minutes to reset the diagnostic control, replug and restart your engine. if your error code does not reappear, then your good. if it does, you should get it checked out to be on the safe side.
