The selective catalytic reduction (SCR) system is a system used to reduce NOx emissions from the engine. Diesel exhaust fluid (DEF) is pumped from the DEF tank and is sprayed into the exhaust stream. The DEF reacts with the SCR catalyst to reduce NOx and leaves a nitrogen and water vapor. The Exhaust Gas Recirculation (EGR) system cools, measures, and introduces recalculated exhaust gas into the intake manifold to aid in NOx reduction.The engine and emissions control system shall be operated, used, and maintained in accordance with the instructions provided to the end user to maintain the emissions performance of the engine within the requirements applicable to the category of the engine. No deliberate tampering with, or misuse of the engine emissions control system should take place. In particular regarding deactivating, or not maintaining the SCR system.
Stopping the engine immediately after the engine has been working under load can result in overheating of SCR components.Refer to the Operation and Maintenance Manual, "Engine Stopping" procedure to allow the engine to cool. Refer to the Operation and Maintenance Manual, "Engine Stopping" procedure to prevent excessive temperatures in the turbocharger housing and the DEF injector.
Allow at least 2 minutes after shutting down the engine before you turn the battery disconnect switch to OFF. Disconnecting the battery power too soon will prevent purging of the DEF lines after the engine is shut down.
Definitions
Observe the following definitions.Self-correct - Fault condition no longer exists. An active fault code will no longer be active.Notification - Action taken by the system to alert the operator of pending Inducement.Inducement - Engine derates, vehicle speed limits, or other actions intended to prompt the operator to repair or maintain the emission control system.Inducement Categories - The Inducements are separated into categories. DEF Levels have inducement fault codes separate from the other inducement categories. DEF level inducements are based on the DEF level, the other inducement categories are based on escalating time. The escalating time inducements will always have an associated fault code along with the inducement fault code. The associated fault is the root cause. The escalating time inducement fault code is just an indicator of what level of inducement the engine is in. The escalating time inducement fault code also indicates how much time remains until the next level of inducement. There are three inducement categories (two for European Union) that will trigger an escalating time inducement fault code.Note: The associated codes for each of the escalating time categories can be found in the Troubleshooting Guide under SCR Warning System Problem.First occurrence - When an escalating time inducement fault code becomes active for the first time.Repeat occurrence - When any escalating time inducement fault code becomes active again within 40 hours of the first occurrence. Engine must run for 40 hours without tripping any escalating time inducement fault before returning get back to first occurrence times.Safe Harbor Mode (Worldwide) - Safe Harbor Mode is a 20 minute engine run time period. During the Safe Harbor Mode (European Union)
