Abstract: A method and system of diagnosing and suggesting least probable faults for an exhibited vehicle failure. The method includes initiating a vehicle health management (VHM) algorithm to monitor a state of health (SOH) for at least one vehicle component at each vehicle operating event over a predetermined time period. The VHM algorithm determines at least one of a Green SOH, a Yellow SOH, and a Red SOH designation with a confidence level for the at least one vehicle component; calculating a number of Green SOH designations (Ncalculated) over the predetermined time period; and upon an exhibited vehicle failure, providing a least probable cause indication for the at least one component when a set of conditions are met. The set of conditions includes (i) Ncalculated is equal to or greater than a predetermined number of Green SOH designations and (ii) no Yellow SOH and Red SOH designations are present.

Abstract: Methods and systems for monitoring no start events for vehicles are provided. In accordance with one embodiment, a vehicle includes an engine, a sensing unit, a processor, and a transmitter. The sensing unit is configured to measure one or more parameter values for a vehicle after a request has been made to start the engine. The processor is coupled to the sensing unit, and configured to determine when a no start event has occurred for the vehicle using the one or more parameter values. The transmitter is coupled to the processor, and is configured to transmit, to a remote server, a no start event history for the vehicle based on the determining by the processor.
