STRAINER ASSEM. 6J2025 - Caterpillar

The "Delayed Engine Shutdown" (DES) feature allows the engine to run after the keyswitch has been turned to the OFF position. "Delayed Engine Shutdown" (DES) allows the engine and exhaust temperatures to cool to an acceptable level prior to shutting the engine down. If the delayed engine shutdown is aborted, potential damage to the engine and/or aftertreatment system can occur. These fault codes indicate that the engine was shut down while the exhaust temperatures were still above the acceptable threshold.Use this procedure in order to troubleshoot the following event codes.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    
J1939 Codes    CDL Code    Code Description
(code descriptions may vary)    Comments    
N/A     E265 (1)     User Defined Shut down     The inputs from the ground level shutdown switch to the Electronic Control Module (ECM) have changed states. The engine will shut down. The code is logged.    
N/A     E265 (2)     User Defined Shut down     The inputs from the ground level shutdown switch to the Electronic Control Module (ECM) have changed states. The engine will shut down. The code is logged.    
N/A     E265 (3)     User Defined Shut down     The inputs from the ground level shutdown switch to the Electronic Control Module (ECM) have changed states. The engine will shut down. The code is logged.    
N/A     E268 (3)     Unexpected Engine Shutdown     The engine has stopped unexpectedly. The engine speed is 0 while the ECM is requesting engine speed.    
6588-31     E1466(1)     Operator Shutdown With High Exhaust Temperature     The Engine was stopped before cooling of the exhaust system could complete. Allow Delayed Engine Shutdown to complete.    Probable Causes for a E1466 or 6588-31 Code
An operator turning the keyswitch to the fourth position or forcing a shutdown prior to DES completing
DES may not be enabled
Fuel ran out prior to DES completion
Mechanical failure causing the engine to stop prior to DES completionProbable Causes for a E265 Code
Activated shutdown switch
Circuit for the shutdown switchProbable Causes for a E268 Code
Operator caused the engine to stall
Fuel supply
Mechanical Failure

Troubleshooting Test Steps    Values    Results    
1. Determine the Code
A. Establish communication between Caterpillar Electronic Technician (ET) and the 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. Determine the event code.
   
Active codes    
Result: An associated code is active.
Refer to Troubleshooting, "Event Codes" in order to troubleshoot the associated diagnostic code.
Troubleshoot the associated code before continuing with this procedure.
Result: A E265 code is active or
