    Abstract: A method and system for diagnosing battery system problems in a vehicle, where the method distinguishes between problems of various battery system components. More particularly, battery connection problems such as loose connections, corroded battery terminals, etc., may be distinguished from battery system problems as a whole. Load related readings that generally reflect the performance of the battery system during a cranking event and one or more non-load related readings may be gathered and used to determine whether there is a battery system problem and whether there is a battery specific problem. If load related readings and/or non-load related readings fail to indicate a battery specific problem, a battery connection problem may be diagnosed.
