1. A computer-implemented diagnostic method for machines having one or more systems, each of the systems having one or more associated electronic controllers, the method comprising:
for a specified machine to be diagnosed, automatically generating a hierarchical list comprising one or more systems associated with a configuration of the specified machine and one or more expected electronic controllers for each of the one or more systems;
at least pursuant to initiation of a diagnostic program via an onboard control unit of the specified machine, obtaining respective input signals from present electronic controllers in functional communication with the onboard control unit;
for each of any expected electronic controllers for which respective input signals are not obtained, generating a status alert corresponding to a determined missing status or failure status, wherein the determined missing or failure status is based at least in part on an optionality of the respective expected electronic controller for which respective input signals are not obtained and/or an optionality of the corresponding system.
