A system, program instructions or method for maintaining a deployed product having at least one component, as well as training of the maintenance workers, is provided. The system has a microserver, a sensor and an electronic device. The microserver is integral with the deployed product. The sensor is in communication with the microserver and operably connected to the component for monitoring parameters of the component. The sensor communicates the parameters to the microserver. The electronic device is in wireless communication with the microserver and remotely located from the microserver. The electronic device receives fault code signals that are generated by the microserver. The fault code signals are representative of a fault code for the component based upon the parameters. The electronic device indicates the fault code for the component. The system can also be used for generating artificial fault codes and evaluating training exercises based upon responses to said artificial fault codes.
