J1939 Code and Description CDL Code and Description Comments
N/A E265 (1)
User Defined Shutdown 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 Shutdown The inputs from the user-defined shutdown switch to the ECM have changed states. The engine will shut down. The code is logged.
N/A E265 (3)
User Defined Shutdown The inputs from the user-defined shutdown switch to the 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
Operator Shutdown With High Exhaust Temperature E1466(1)
Operator Forced 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

Improper operation of engine
Machine is not in safe state for DES
Parking break is not engaged
Transmission is not in neutral
Any occurrence that results in engine shutdown prior to DES completion
Depletion of fuel resulting in engine shutdown
Operator forced engine shutdown
Mechanical failureProbable Causes for a E265 Code
Activated shutdown switch
Circuit for the shutdown switchProbable Causes for a E268 Code
Operator caused the engine to stall

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A E265 code is active or logged.
Proceed to Test Step 6.
Result: A E268 (3) code is active or logged.
Proceed to Test Step 3.
Result: A E1466 or 6588-31 code is active or logged.
Proceed to Test Step 2.
2. Check if the "Delayed Engine Shutdown" Is Enabled
A. Connect Cat ET.
B. Navigate to the "Configuration" tab in the engine ECM.
C. Use Cat ET to monitor the following parameter:
-"Delayed Engine Shutdown"
Delayed Engine Shutdown
Result: The "Delayed Engine Shutdown" is enabled.
Proceed to Test Step 3.
Result: The "Delayed Engine Shutdown" is not enabled.
Repair: Enable "Delayed Engine Shutdown".
If the problem is not resolved, proceed to Test Step 3.
3. Proper Engine Operation
A. Interview the operator and determine the events that caused the engine to stall. Refer to Operation and Maintenance Manual (OMM) for proper engine operation.
Note: The Delayed Engine Shutdown (DES) may not have completed.
Operator
Result: The operator is operating the engine correctly.
Proceed to Test Step 4.
Result: The operator is not operating the engine correctly.
Repair: Operate the engine correctly.
If the problem is not resolved, proceed to Test Step 4.
4. Inspect the Fuel System
Refer to Testing and Adjusting, "Fuel System Inspection" for additional information.
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the vent in the fuel cap is not filled with debris.
C. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
Note: Cold weather adversely affects the characteristics of the fuel. Refer to the engines Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation.
D. Check fuel quality. Refer to Testing and Adjusting, "Fuel Quality - Test" for additional information. Check the fuel tank for debris or foreign objects which may block the fuel supply.
E. Check for fuel leaks.
Fuel System
Result: The fuel system is OK.
Proceed to Test Step 5.
Result: The fuel system is NOT OK.
Repair: Repair or replace damaged fuel system components.
If the problem is not resolved, proceed to Test Step 5.
5. Check for a Mechanical Failure
Mechanical Failure
Result: A mechanical failure has occurred.
Repair: Repair or replace damaged components.
Verify that the repair eliminated the problem.
6. Check for an Activated Shutdown Switch
A. Interview the operator and determine the reason for the emergency stop shutdown.
Switch
Result: The emergency shutdown was not activated.
Proceed to Test Step 7.
Result: The emergency stop shutdown was activated.
Repair: Diagnose the problem and then repair the problem.
If the problem is not resolved, proceed to Test Step 7.
7. Check the Emergency Shutdown Switch Circuit
A. Inspect the stop switches for evidence of damage that has been caused by vibration, moisture, or corrosion.
B. Check the circuit for the shutdown switch. Refer to Troubleshooting, "Shutdown (Ground Level) - Test" for additional information.
Emergency Shutdown Switch Circuit
Result: The emergency stop shutdown switch is not operating properly or there is a problem with the emergency shutdown circuit.
Repair: Repair or replace the failed component.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
