Abstract

A system includes an exhaust aftertreatment system coupled to an engine and a controller. The controller includes at least one processor coupled to at least one memory device storing instructions that, when executed by the at least one processor, cause the controller to perform operations including: determine an intended emissions level calibration parameter; receive a new emissions level calibration parameter; compare the intended emissions level calibration parameter to the new emissions level calibration parameter; and generate an alert based on the comparison.
