ROLL SET 7B5060 - 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 may 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.

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 user-defined 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 user-defined 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 user-defined 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
