2. A E1239 (1), E1239 (2), E1239 (3), 3750-31, 3750-17 or 3750-18 Diagnostic Code is Present.
A. The operator did not allow a regeneration to occur or an automatic regeneration did not occur within the required time limit. The operator must respond when the DPF lamp is illuminated.
B. Perform a "Forced Regeneration" by pressing the "Regeneration Force Switch" button.
   
Forced Regeneration
   
Result: The "Forced Regeneration" was successful.
Return the unit to service.
Result: The "Forced Regeneration" was not successful.
Repair: Troubleshoot the active diagnostic codes.
   
3. A E993 (3) or 3703-31 Diagnostic Code is Present.
A. The operator has disabled the regeneration system and a regeneration is necessary.
   
Disabled Regeneration
   
Result: Perform a regeneration. Refer to the Operation and Maintenance Manual, "Diesel Particulate Filter Regeneration" for the proper operation of the regeneration system.
Return the unit to service.
   
4. A E1040 (2) or 3530-31 Diagnostic Code is Present.
A. The regeneration system is disabled by Cat ET.
   
Regeneration Disabled by Cat ET.
   
Result: Establish communication between Cat ET and the engine ECM. Set the value of the "Aftertreatment Regeneration Device" from "Disabled" to "Enabled".
Return the unit to service.
   
5. Aftertreatment Regeneration Cannot Start Due To Low Engine Temperature
A. The engine temperature is too low for an aftertreatment regeneration.
   
Low Engine Temperature
   
Result: Raise the coolant temperature above
40° C (104° F ) and the Diesel Particulate Filter inlet temperature above
50° C (122° F). If the ambient temperature is
-15° C (5° F) or below, the coolant temperature must be above
60° C (140° F) for an active regeneration to begin.
Return the unit to service.
   
6. Aftertreatment Regeneration Cannot Start Due to System Fault
A. Establish communication between the Caterpillar Electronic Technician (ET) and the engine Electronic Control Module (ECM).
B. Check for active faults related to the ARD combustion air system, ARD fuel system,
