Systems and methods for monitoring health of one or more subsystems of a vehicle system are disclosed. At least one sensor can be operatively coupled to a vehicle subsystem having an operational signature and a control system is coupled to the at least one sensor. Using information provided by the at least one sensor, the control system is structured to generate a reference signature of the subsystem during a learning phase and an operational signature of the subsystem subsequent to the learning phase. Systems and methods for identifying the particular subsystem exhibiting degraded performance are also disclosed. 1. A system comprising:a powertrain including a plurality of associated subsystems;each of the subsystems including at least one sensor, the sensors being structured to generate operational values associated with the respective subsystem to which each sensor is coupled; generate a reference signature for each of the subsystems based on the operational values generated by the associated sensor during a learning phase of powertrain and subsystem operation by a user, wherein each of the reference signatures includes a learned normal average, a learned maximum, and a learned minimum of the operational values of the associated subsystem over the learning phase;', 'record the reference signatures for each of the subsystems in a memory of the control system;', 'generate an operational signature for each of the subsystems during operation of the powertrain subsequent to the learning phase, wherein the operational signatures each include a running average, a maximum, and a minimum of the operational values of the subsystem generated by the at least one sensor since the learning phase;', 'record the operational signatures for each of the subsystems in the memory; and', 'output the operational signatures and the reference signatures., 'a control system coupled to each of the sensors, the control system being configured to2. The system of claim 1 , wherein at least one ...
