METHOD AND APPARATUS TO EVALUATE A STARTING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

A starting system for an internal combustion engine includes a starter motor and a battery. A method for evaluating the starting system includes detecting a fault associated with the starter motor when a minimum starting system voltage during a cranking event is greater than a threshold minimum starting system voltage determined in relation to an engine acceleration parameter, and detecting a fault associated with the battery when the engine acceleration parameter is less than a minimum threshold for the engine acceleration parameter.
