Diagnostic Trouble Codes
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
3483-11 E1305 (1) Initial Assembly Aftertreatment #1 Procedure Required Initial assembly of the aftertreatment system is complete or the Engine ECM or the A5:E2 Aftertreatment Controller was replaced.
3530-31 E1040 (2) ARD Manually Disabled The regeneration system is disabled by the electronic service tool.
3716-15 E1300 (1) Aftertreatment Regeneration Cannot Start Due to Low Engine Temperature The coolant temperature is below 40° C (104° F) and the Diesel Particulate Filter inlet temperature is below 50° C (122° F).
If the ambient temperature is 0° C (32° F) or below, the coolant temperature must be 60° C (140° F) for active regeneration to begin.
3703-31 E993 (3) DPF Active Regeneration Inhibited Due to Inhibit Switch The regeneration system is disabled due to the ARD Disable Switch in the operator interface.
3712-15 E1301 (1) Aftertreatment Regeneration Cannot Start Due To System Fault There is an active fault related to the ARD combustion air system, ARD fuel system, or ARD ignition system.
3716-31 E1300 (2) Aftertreatment Regeneration Cannot Start Due To Low Engine Temperature The coolant temperature is below 40° C (104° F) and the Diesel Particulate Filter inlet temperature is below 50° C (122° F).
If the ambient temperature is 0° C (32° F) or below, the coolant temperature must be 60° C (140° F) for active regeneration to begin.
3750-15 E1302 (1) Aftertreatment Regeneration Cannot Start Due To Conditions Not Met One or more conditions are not allowing an Aftertreatment Regeneration to start, Refer to Test Step 7.
3750-31 E1239 (1) DPF #1 Conditions Not Met for Active Regeneration The operator did not allow enough time for regeneration to occur. The operator must respond when the DPF lamp is illuminated. The operator must allow the engine to idle until the regeneration is complete. Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Check for Diagnostic Codes that are Active
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Check and record any event codes that are active or logged.
Diagnostic Code
Result: A 3750-31 (E1239 (3)) diagnostic code is present.
Proceed to Test Step 2.
Result: A 3703-31 (E993 (3)) diagnostic code is present.
Proceed to Test Step 3.
Result: A 3530-31 (E1040 (2)) diagnostic code is present.
Proceed to Test Step 4.
Result: A 3716-15 (E1300 (1)) or 3716-31 (E1300 (2)) diagnostic code is present.
Proceed to Test Step 5.
Result: A 3712-15 (E1301 (1)) diagnostic code is present.
Proceed to Test Step 6.
Result: A 3750-15 (E1302 (1)) or diagnostic code is present.
Proceed to Test Step 7.
Result: A 3483-11 (E1305 (1)) diagnostic code is present.
Proceed to Test Step 8.
2. A 3750-31(E1239 (1))
A. The operator did not allow regeneration to occur or 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 3703-31E993 (3) Diagnostic Code is Present
A. The operator has disabled the regeneration system and regeneration is necessary.
Disabled Regeneration
Result: Perform a manual DPF 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 3530-31 (E1040 (2)) Diagnostic Code is Present
A. The regeneration system is disabled by the electronic service tool.
Regeneration Disabled by the electronic service tool.
Result: Establish communication between the electronic service tool and the engine ECM. Set the value of the "Aftertreatment Regeneration Device" from "Disabled" to "Enabled".
Return the unit to service.
5. A 3716-15 (E1300 (1)) or 3716-31 (E1300 (2)) diagnostic code is present
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 active regeneration to begin.
Return the unit to service.
6. A 3712-15 (E1301 (1)) diagnostic code is present.
Note: Aftertreatment regeneration cannot start due to a system fault.
A. Establish communication between the electronic service tool and the engine Electronic Control Module (ECM).
B. Check for active faults related to the ARD combustion air system, ARD fuel system, or ARD ignition system.
System Fault
Result: Troubleshoot all active faults related to the ARD combustion air system, ARD fuel system, or ARD ignition system. Clear any active codes after correcting the faults. Activate regeneration.
Return the unit to service.
7. A 3750-15 (E1302 (1)) or diagnostic code is present
Note: Aftertreatment regeneration
