A computing system is structured to receive operating data provided by a telematics circuit associated with a remote engine. The operating data comprises information provided by at least one sensor and/or at least one actuation command. The computing system is structured to determine, based on the operating data, a plurality of field-replaceable units (FRUs) associated with the operating data. The computing system is structured to generate a computer-based simulation corresponding to at least one degradation level for an FRU from the plurality of FRUs, identify a most probable failure, and rank the computer-based simulations across the plurality of FRUs. The computing system is structured to generate an electronic notification comprising data associated with the most probable failure and transmit the electronic notification to a computing device.
