Abstract:
An internal combustion engine including a starter is shown. A method for monitoring the starter includes determining electrical energy consumed by pinion and motor solenoids operative to activate and rotate a pinion gear of an electrically-powered motor meshingly engageable to a starter ring gear portion of a flywheel of the engine during an engine starting event. Current ringing in the pinion and motor solenoids is monitored during the engine starting even, and a fault is identified in the pinion and motor solenoids based upon the current ringing and the electrical energy consumption of the starter during the engine starting event.
