Selective Catalytic Reduction (SCR) Engines Engine controls the production of particulate matter (PM), thus limiting it within the permissible value, while SCR is an exhaust after treatment device to reduce NOx. SCR spreads aqueous urea solution (AUS 32) into the exhaust stream. Ammonia from AUS32 combines with NOx in presence of catalyst to form harmless by-products like nitrogen and water vapor.1. Use a diagnostic tool. The first step in clearing the fault codes on your SCR system is to use a diagnostic tool, such as Mack’s diagnostic software, to retrieve the codes. Once you have the codes, you can use the tool to clear them from the system’s memory.
