CDL Code    J1939 Code    Code Description
(code descriptions may vary)    Comments    
E593 (2)     3711-31     Aftertreatment Insufficient Temperature to Complete Regeneration     Active regeneration failed due to an inability of the Diesel Particulate Filter (DPF) to reach a high enough temperature. The code is logged. Engine power is derated.    
Follow the troubleshooting procedure in order to identify the root cause of the problem.    Illustration 1 and Illustration 2 show the location of the components for the ARD system.

Troubleshooting Test Steps    Values    Results    
1. Check for Associated Diagnostic Trouble Codes
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. Table 2 lists the diagnostic trouble codes that are associated with the E593 (2) or 3711-31 code. Determine if any of the codes in Table 2 are present.
   
Diagnostic code
   
Result: An associated diagnostic trouble code is not present.
Proceed to Test Step 2.
Result: An associated diagnostic trouble code is present.
Troubleshoot the associated diagnostic code.
   
2. Check the Current Flow Through the Heater
A. Verify that the engine is off. Check the current flow through the heater. Refer to Systems Operation/Testing and Adjusting, "ARD Nozzle Heater - Test" for the correct procedure.
   
Between 7.0 A and 14 A for a 12 V system. Or, between 3.5 A and 7 A for a 24 V system
   
The current flow is between 7.0 A and 14 A for a 12 V system. Or, the current flow is between 3.5 A and 7 A for a 24 V system.
Result: The current flow is OK.
Proceed to Test Step 3.
Result: The current flow is not between 7.0 A and 14 A for a 12 V system. Or, the current flow is not between 3.5 A and 7 A for a 24 V system.
There may be a problem with the ARD nozzle. Refer to Troubleshooting, "ARD Nozzle - Test".
   
3. Perform the "ARD Air System Service Test"
A. Reset all active codes. Use Cat ET to perform an "ARD Air System Service Test" in order to verify that the problem is resolved. Refer to Troubleshooting, "ARD Combustion Air - Test".
   
ARD Air System Service Test
   
Result: The "ARD Air System Service Test" failed.
There is a problem with the ARD combustion air. Refer to Troubleshooting, "ARD Combustion Air - Test".
Result: The "ARD Air System Service Test" passed.
Proceed to Test Step 4.
   
4. Perform a "Manual DPF Regeneration"
This test must be performed through Cat ET. The Cat ET service tool enhances the diagnostics during the service test.
A. Clear "Active" codes using Cat ET.
B. Click the "Disconnect" icon on Cat ET in order to disconnect Cat ET from the engine ECM.
C. Turn the keyswitch to the Off position. Wait for 5 seconds.
D. Turn the keyswitch to the On position.
E. Click the "Connect" icon on Cat ET in order to connect Cat ET to the engine ECM.
F. Start the engine. Allow the engine to idle for 3 minutes.
Do not use the operators switch for a stationary regeneration. The service tests provide enhanced diagnostics that are necessary for proper troubleshooting and repair.
G. Start a "Manual DPF Regeneration" in Cat ET.
   
Manual DPF Regeneration
   
Result: The "Manual DPF Regeneration" completed successfully. There are no additional codes.
Return the unit to service.
Result: The "Manual DPF Regeneration" did not complete successfully.
Check the list of active diagnostic codes. Troubleshoot the code that applies to the failed regeneration. Refer to Table 2 for associated codes.
Result: The "Manual DPF Regeneration" did not complete successfully and there are no associated codes.
Proceed to Test Step 5.
