Abstract:
1. A system, comprising: an internal combustion engine; a controller to control operation of the internal combustion engine; an aftertreatment system coupled to the internal combustion engine to receive an exhaust gas stream from the internal combustion engine, the aftertreatment system including at least one component for treatment of constituents in the exhaust gas stream, wherein the at least one component includes a sensor associated therewith; and a connection device associated with the at least one component that is electrically connected to the controller, the connection device including a housing and an indicator device in the housing that is connected between the sensor and the controller with a wiring harness, the indicator device including one or more capacitors in parallel with the sensor and the controller, the one or more capacitors configured to generate an input signal to the controller corresponding to a unique capacitance value that identifies the at least one component, wherein the controller is configured to determine, based on the input signal, whether the at least one component is approved for use with the internal combustion engine.
