Abstract: A system includes prime mover structured to generate power for a mobile vehicle; a power converter structured to receive a portion of the generated power, and to provide configured electrical power to an electric heater device configured to selectively heat an exhaust fluid of the prime mover; at least one aftertreatment component positioned downstream of the electric heater device, and configured to treat at least one constituent of the exhaust fluid; and a controller, including: an operating conditions circuit structured to interpret an operating parameter of at least one of the power converter, the electric heater device, or the exhaust fluid; an aftertreatment diagnostic circuit structured to determine a component diagnostic value in response to the operating parameter; and an emissions reporting circuit structured to transmit an emissions description in response to the component diagnostic value.
