Systems and methods for diagnosing component failure

A method for diagnosing at least one component in an exhaust aftertreatment system, the method comprising:

• causing an engine to operate through a sequence of a plurality of engine outputs;
• receiving, from at least one sensor, a first set of sensor data corresponding to a first engine output;
• diagnosing the at least one component based on the first set of sensor data, the diagnosis indicating a failure type;
• and
• causing at least one of the engine or an electric machine coupled to the engine to operate based on the failure type.

A non-transitory computer-readable medium having computer-executable instructions embodied therein that, when executed by at least one processor of a computing system, cause the computing system to perform operations comprising:

• causing an engine to operate through a sequence of a plurality of engine outputs;
• receiving, from at least one sensor, a first set of sensor data corresponding to a first engine output;
• diagnosing at least one component based on the first set of sensor data, the diagnosis indicating a failure type;
• and
• causing at least one of the engine or an electric machine coupled to the engine to operate based on the failure type.
