Illustration 31 g03534876Reduced Performance
When the ECM is configured to "Reduced Performance" and the DEF level is below 1%, the engine will be in level 2 inducement. A 1761-18 or E954 (2) Aftertreatment #1 Diesel Exhaust Fluid Tank Level : Low - moderate severity (2) diagnostic code will become active. The CEL and EMIL 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 and be limited 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 3 key cycles.Reduced Time
When ECM is configured to "Reduced Time" and the DEF level is below 7.5%, a 1761-18 or E954 (2) Aftertreatment #1 Diesel Exhaust Fluid Tank Level: Low - moderate severity (2) diagnostic code will become active. The CEL and EMIL will illuminate and flash slowly. The DEF level gauge amber lamp will remain lit.Level 3 Inducement

Reduced Time
If the ECM is configured to "Reduced Time" and the DEF level is 0%, a 1761 -1 or E954 (3) Aftertreatment #1 Diesel Exhaust Fluid Tank Level : Low - most severe (3) diagnostic code will become active. The CEL and EMIL will illuminate and flash at a fast rate. An action lamp or 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 Cat ET is set to "Idle Down", then engine will continue to idle at derated condition. If set to "Shutdown", engine will shutdown after 5 minutes. Safe Harbor Mode is allowed for 3 key cycles. After Safe Harbor Mode is completed, the engine will return to idle or shutdown. If in shutdown configuration, the engine may be restarted, but will only run for 5 minutes at derated condition before shutting down again. This action will continue until the issue is resolved.Note: Turn the key to the OFF position and add DEF to the DEF tank to reset the DEF level inducement.Inducement Strategy (European Union)
