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 Caterpillar Electronic Technician (ET).
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 an active regeneration to begin.
3703-31 E993 (2) 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 an 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.
3750-17 E1239 (2) DPF #1 Conditions Not Met for Active Regeneration The operator did not allow a regeneration to occur and 32 hours has elapsed since the last successful regeneration. The operator must respond when the DPF lamp and action lamp is illuminated. This event will trigger a 50% derate.
3750-18 E1239 (3) DPF #1 Conditions Not Met for Active Regeneration The operator did not allow a regeneration to occur and 38.4 hours has elapsed since the last successful regeneration. The operator must respond when the DPF lamp, action lamp is illuminated and audible alarm sounds in the cab. This event will trigger a 100% derate.
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 Cat® ET and the Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Check and record any event codes that are active or logged.
Diagnostic Code
Result: A E1239 (1), E1239 (2), E1239 (3), 3750-31, 3750-17 or 3750-18 diagnostic code is present, proceed to Test Step 2.
Result: A E993 (3) or 3703-31 diagnostic code is present, proceed to Test Step 3.
Result: A E1040 (2) or 3530-31 diagnostic code is present, proceed to Test Step 4.
Result: An E1300 (1), E1300 (2), 3716-15 or 3716-31 diagnostic code is present, proceed to Test Step 5.
Result: A E1301 (1) or 3712-15 diagnostic code is present, proceed to Test Step 6.
Result: A E1302 (1) or 3750-15 diagnostic code is present, proceed to Test Step 7.
Result: A E1305 (1) or 3483-11 diagnostic code is present, proceed to Test Step 8.
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
