DESA’s Aftertreatment Health Analysis Test was created to help systematically diagnose complex engine and Aftertreatment

systems. The application will run a dynamic self-test of the Aftertreatment System and key Engine Systems, create a log file

and provide an analysis of that log file in order to better guide diagnostics.
