Diagnostic Trouble Codes for Engine Shutdown Occurrence
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
970-15 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 stop. The code is logged.
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 6588-31 (E1466) 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 970-15 (E265) Code
Activated shutdown switch
Circuit for the shutdown switch

Troubleshooting Test Steps Values Results
1. Determine the Code
A. Establish communication between the electronic service tool 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.
Repair: Refer to Troubleshooting, "Event Codes" to troubleshoot the associated diagnostic code.
Note: Troubleshoot the associated code before continuing with this procedure.
Result: A 6588-31 or E1466 (1) code is active or logged.
Proceed to Test Step 2.
Result: A 970-15 (E265 (1)) code is active or logged.
Proceed to Test Step 5.
2. Delayed Engine Shutdown
Note: This Test Step is only applicable to applications that do not have a DEF injector cooling tank. Applications that have a DEF injector cooling tank should have Delayed Engine Shutdown disabled. For these applications, proceed to Test Step 3.
A. Check if "Delayed Engine Shutdown" is enabled.
B. Connect to the electronic service tool and then navigate to the "Configuration" tab in the engine ECM. Select the "Delayed Engine Shutdown" tab and check the status of the parameter.
Delayed engine shutdown
Result: "Delayed Engine Shutdown" is enabled.
Proceed to Test Step 3.
Result: "Delayed Engine Shutdown" is not enabled.
Repair: Enable "Delayed Engine Shutdown".
Verify that enabling "Delayed Engine Shutdown" eliminated the fault.
3. Fuel
A. Check the engine fuel supply.
Fuel
Result: The engine is out of fuel.
Repair: Fill the fuel tank with fuel of the correct specification.
Verify that the repair eliminated the fault.
Result: The engine is not out of fuel.
Proceed to Test Step 4.
4. Mechanical Failure
A. Check for a mechanical failure.
Mechanical failure
Result: A mechanical failure has occurred.
Repair: Diagnose and then repair the fault.
Verify that the repair eliminated the fault.
5. Activated Shutdown Switch
A. Interview the operator and determine the reason for the emergency stop shutdown.
Emergency shutdownswitch
Result: The emergency stop shutdown was activated.
Repair: Diagnose and repair the fault.
Verify that the repair eliminated the fault.
Result: The emergency shutdown was not activated.
Proceed to Test Step 6.
6. 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".
Emergency shutdown switch circuit
Result: The emergency stop shutdown switch is not operating correctly or there is a fault in the emergency shutdown circuit.
Repair: Repair or replace the failed component.
Verify that the repair eliminated the fault.
If the fault is still present, contact the Dealer Solutions Network (DSN).
