Table 1
Diagnostic Trouble Codes    
CDL Code    J1939 Code    Code Description
(code descriptions may vary)    Comments    
E1239 (1)     3750-31     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 soot load is reduced to 50 percent. Refer to the Operation and Maintenance Manual for information on performing a manual regeneration.    
E993 (2)     3703-31     DPF Active Regeneration Inhibited Due to Inhibit Switch     The regeneration system is disabled due to the ARD Disable Switch in the operator interface.    
E1040 (2)     3530-31     ARD Manually Disabled     The regeneration system is disabled by the Caterpillar Electronic Technician (ET).    
E1300 (1)     3716-15     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.    
E1300 (2)     3716-31     Aftertreatment Regeneration Cannot Start Due To Low Engine Temperature     The DPF soot loading exceeded 100% when the ambient temperature was below
0° C (32° F) and coolant temperature was below
50° C (122° F). A regeneration was attempted but failed. Automatic regenerations are disabled, Refer to Test Step 5.    
E1301 (1)     3712-15     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.    
E1302 (1)     3750-15     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.    
E1305 (1)     3483-11     Initial Assembly Aftertreatment #1 Regeneration Required     Initial assembly of the aftertreatment system is complete and an active regeneration has not been performed or the engine ECM has been replaced and an active regeneration has not been performed.

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 diagnostic codes that are active or logged. Look for the following diagnostic codes:
1. E1239 (1) or 3750-31
2. E993 (3) or 3703-31
3. E1040 (2) or 3530-31
D. Wait at least 30 seconds in order for the diagnostic codes to become active.
   
Diagnostic Code
   
Result: A E1239 (1) or 3750-31 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: A E1300 (1) or 3716-15 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) or 3750-31 Diagnostic Code is Present.
A. The operator did not allow enough time for regeneration to occur. The operator must respond when the DPF lamp is illuminated. Once the DPF and action lamp are illuminated, the operator must allow the engine to idle until the soot load is reduced to 50 percent .
   
Proper Operation
   
Result: Refer to the Operation and Maintenance Manual, "Caterpillar Regeneration System (CRS) Aftertreatment Switch" for the proper operation of the regeneration system.
Return the unit to service.
   
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, "Caterpillar Regeneration System (CRS) Aftertreatment Switch" 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.
Repair: Perform a "Manual DPF Regeneration" using Cat ET.
Return the unit to service.
   
6. Aftertreatment Regeneration Cannot Start Due to System Fault
A. Establish communication between the Cat 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, or ARD ignition system.
   
System Fault
