RETAINER 3S1262 - Caterpillar

Table 1 lists the diagnostic code that relates to low Aftertreatment Regeneration Device (ARD) temperature.Note: Refer to Troubleshooting, "Cat ET Service Features" for information about service features.Clear all "Active" codes using Cat ET before proceeding with the following procedure. Refer to Troubleshooting, "Diagnostic Capabilities - Clearing Active Codes for On Board Diagnostics (OBD)" for more information on clearing "Active" codes.

Diagnostic Trouble Codes    
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
