Abstract
A method for monitoring a starter motor for an internal combustion engine includes calculating a first engine power during a starting event based on an electric power flow from the battery to the starter motor, calculating a second engine power during the starting event based on an engine kinetic energy, and detecting a fault associated with the starter motor as a function of the difference between the first engine power and the second engine power.
