1. A system for use in maintenance of a vehicle that includes vehicle systems configured to report faults to an onboard reasoner, the system comprising:
an onboard computer including the onboard reasoner that is configured to receive a fault report indicating failed tests reported by a vehicle system, diagnose a failure mode onboard the vehicle, from the failed tests, and using an onboard diagnostic model that represents or describes known relationships between possible failed tests reported by the vehicle systems, and possible failure modes onboard the vehicle systems, the onboard reasoner further configured to determine a service recommendation of a service action to address the failure mode; and
an off-board computer including an off-board copy of the onboard reasoner configured to receive the fault report indicating the failed tests, and further address the fault report based on a measure of fix effectivity of the service action, including the off-board copy of the onboard reasoner configured to at least:
receive the measure of fix effectivity of the service action as performed to address the failure mode;
diagnose the failure mode or an alternate failure mode onboard the vehicle, from the failed tests and the measure of fix effectivity of the service action, and using an off-board copy of the onboard diagnostic model; and responsive to diagnosis of the alternate failure mode,
determine a maintenance recommendation of a maintenance action to address the alternate failure mode; and
generate a maintenance message including the maintenance recommendation.
