Diagnostics for identifying a malfunctioning component in an air compressor system onboard a locomotive
First Claim
1. A method for identifying one or more malfunctions from a plurality of malfunctions that can occur in a locomotive air compressing system comprising a plurality of components, with at least some of said plurality of malfunctions being correctable onboard a locomotive, said at least some malfunctions constituting onboard serviceable malfunctions, while a remaining of said plurality of malfunctions are correctable with the air compressing system being uninstalled and serviced at an off-board servicing site, said remaining malfunctions constituting off-board serviceable malfunctions, said method comprising:
- performing a test sequence configured to isolate components of the air compressing system from one another to identify a component subject to a malfunction;
applying a pressurizing stimuli to the isolated components;
monitoring a response indicative of a malfunction type, the malfunction type being associated with one of the following;
a corrective action to be performed onboard the locomotive, and a corrective action to be performed off-board the locomotive; and
performing the corrective action appropriate for the malfunction type.

Abstract
A method and computer program product for identifying one or more malfunctions in a locomotive air compressing system is provided. Some of the malfunctions may be correctable onboard a locomotive, and constitute onboard serviceable malfunctions, while the remaining of the malfunctions may only be correctable with the air compressing system being uninstalled and serviced at an off-board servicing site, such malfunctions constitute off-board serviceable malfunctions. The method allows monitoring responses indicative of a malfunction type that may be associated with at least with one of the following: a corrective action that may be performed onboard the locomotive, and a corrective action that may only be performed off-board the locomotive.
