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 the engine can be operated with full power after reaching a level 3 inducement. Once in level 3 inducement, the operator can perform a key cycle and the engine will enter Safe Harbor Mode. Safe Harbor Mode can only be implemented once. Safe Harbor Mode is not allowed for DEF level inducements with Worldwide configuration.Safe Harbor Mode (European Union) - Safe Harbor Mode is a 30 minute engine run time period. During the Safe Harbor Mode the engine can be operated with full power after reaching a level 3 inducement. Once in level 3 inducement, the operator can perform a key cycle and the engine will enter Safe Harbor Mode. Safe Harbor Mode can only be implemented up to three times.
It is essential to take prompt action to rectify any incorrect operation, use, or maintenance of the emissions SCR control system in accordance with the rectification measures indicated by the warnings listed on the following pages.

Inducement Strategy for DEF Level (European Union)
Illustration 2 g03676107If the DEF level falls below 20%, an amber indicator will illuminate next to the DEF level gauge on the dash. To avoid further inducements, turn the key to the OFF and add DEF to the DEF tank.
Illustration 3 g03676111If the DEF level falls below 13.5%, a level 1 inducement event will occur. The check engine lamp and the emissions malfunction indicator lamp will illuminate. The amber indicator next to the DEF level gauge on the dash will remain lit.
Illustration 4 g03676123Reduced PerformanceWhen the ECM is configured to "Reduced Performance" and the DEF level is below 1%, the engine will be in level 2 inducement. The check engine lamp and emissions malfunction indicator lamp will illuminate and flash slowly. The DEF level gauge amber lamp will remain lit. The engine will have a 50% derate. When the DEF tank has been emptied of all DEF, the engine will have a 100% derate. An empty DEF tank also limits the engine to 1000 rpm or low idle, whichever is greater. No further inducement action will occur for "Reduced Performance" configuration. Safe Harbor Mode is allowed for three key cycles.Reduced TimeWhen the ECM is configured to "Reduced Time" and the DEF level is below 7.5%, the engine will be in level 2 inducement. The check engine lamp and emissions malfunction indicator lamp will illuminate and flash slowly. The DEF level gauge amber lamp will remain lit.
Illustration 5 g03676127Reduced TimeIf the ECM is configured to "Reduced Time" and the DEF level is 0%, the engine will be in level 3 inducement. The check engine lamp and emissions malfunction indicator lamp will illuminate and flash at a fast rate. A red stop lamp will illuminate solid. The DEF level gauge amber lamp will remain lit. The engine will have a 100% derate and be limited to 1000 rpm or low idle, whichever is greater. If the final inducement action in ET is set to "Idle Down", then the engine will continue to idle at derated condition. If set to "Shutdown", engine will shut down after 5 minutes
