DEF Tank Level Inducement
DEF Tank Level Fault Occurrence
Two options are available but only one option will be enabled.Option 1 - Reduced Performance (Derates)Option 1 is the default setting for inducement. If the DEF level falls below 20%, an amber indicator will illuminate below the DEF level gauge on the panel. To avoid further inducements, add DEF to the DEF tank.Level 1: If the DEF level falls below 13.5%, the Emissions System Malfunction lamp will illuminate. The amber indicator next to the DEF level gauge on the panel will continue to remain lit.Level 2 (Mild): If the DEF level is below 7.5%, the Emissions System Malfunction lamp will flash slowly. The amber indicator below the DEF level gauge on the panel will remain lit. Level 2 (Severe): If the DEF level falls below 1% without a loss of DEF pressure, the engine is derated by 25% torque over a 10 minute period.Level 3: When the DEF level falls below 3% with a loss of DEF pressure, the engine enters a 5 minute cool down period. The engine is derated by 100% torque. The reduced performance is followed by engine at low idle only or engine shutdown. The following indications will be present:
The Emissions System Malfunction lamp will flash quickly
The Shutdown lamp will be on
The engine will be restricted to low idle or will be shut down
The amber indicator below the DEF level gauge on the panel will be lit.

To avoid further inducements, add DEF to the DEF tank.Level 1: If the DEF level falls below 13.5%, the Emissions System Malfunction lamp will illuminate. The amber indicator next to the DEF level gauge on the panel will continue to remain lit.Level 2: If the DEF level is below 7.5%, the Emissions System Malfunction lamp will flash slowly. The amber indicator below the DEF level gauge on the panel will remain lit.Level 3: If the DEF level is below 3%, the engine enters a 5 minute cool down period. The engine is derated by 100% torque. The following indications will be present:
The Emissions System Malfunction lamp will flash quickly
The Shutdown lamp will be on
The amber indicator below the DEF level gauge on the panel will be lit.
Illustration 2 g03813924Tampering/Dosing Interruption
The Emissions System Malfunction lamp will illuminate for a fault resulting from SCR system tampering or an SCR system fault. If the fault is the result of system tampering, a first occurrence will result in a level 1 inducement for a duration of 2.5 hours. Repeat occurrences will result in a level 1 inducement duration of 5 minutes.If a fault condition exists for the entire duration of inducement level 1, the strategy advances to inducement level 2. For a fault resulting from SCR system tampering or an
