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 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.
Troubleshoot the associated code before continuing with this procedure.
Result: A E265 code is active or logged.
Proceed to Test Step 6.
Result: A E268 (3), E369 (3), or 5272-31 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. Delayed Engine Shutdown
A. Check if "Delayed Engine Shutdown" is enabled.
B. Connect to Cat® ET, 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 problem.
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.
B. 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.
4. Fuel
A. Check the engine fuel supply.
Fuel
Result: The engine is out of fuel.
Repair: Supply the engine with an adequate fuel supply.
Verify that the repair eliminated the problem.
Result: The engine is not out of fuel.
Proceed to Test Step 5.
5. Mechanical Failure
A. Check for a mechanical failure.
Mechanical Failure
Result: A mechanical failure has occurred.
Repair: Diagnose the problem and then repair the problem.
Verify that the repair eliminated the problem.
6. Activated Shutdown Switch
A. Interview the operator and determine the reason for the emergency stop shutdown.
Switch
Result: The emergency stop shutdown was activated.
Repair: Diagnose the problem and then repair the problem.
Verify that the repair eliminated the problem.
Result: The emergency shutdown was not activated.
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".
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.
