Troubleshooting Test Step    Value    Result    
1. Check for Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if the diagnostic trouble code that directed to this procedure is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this procedure.
   
E539
   
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: An E539 code is present.
Proceed to the next step.
Result: No active codes
STOP
   
2. Check for High Inlet Air Temperature
A. Check for a high inlet air temperature.
Refer to Troubleshooting, "Inlet Air Temperature Is High".
   
Temperature
   
Result: The inlet air temperature is OK.
Proceed to the next step.
Result: The inlet air temperature is NOT OK.
Repair: Determine the cause of the high inlet air temperature and correct the problem.
If the problem is not resolved, proceed to the next step.
   
3. Check for High Coolant Temperature
A. Check for a high coolant temperature for the engine.
Refer to Troubleshooting, "Coolant Temperature Is High".
   
Temperature
   
Result: The coolant temperature is OK.
Proceed to the next step.
Result: The coolant temperature is NOT OK.
Repair: Determine the cause of the high coolant temperature and correct the problem.
If the problem is not resolved, proceed to the next step.
   
4. Check for Inlet Air Restriction
A. Check for inlet air restriction.
Refer to Troubleshooting, "Inlet Air Is Restricted".
A restriction of the inlet air can cause high cylinder temperatures.
High cylinder temperatures can cause a high coolant temperature.
   
Exhaust
restriction
   
Result: The inlet air is not restricted.
Proceed to the next step.
Result: The inlet air is restricted.
Repair: Determine the reason for high inlet air restriction and repair.
If the problem is not resolved, proceed to the next step.
   
5. Check for Exhaust Restriction
A. Measure the exhaust restriction during engine operation with a load. For data that is specific to your engine, refer to the Technical Marketing Information (TMI).
A restriction in the exhaust system can cause high cylinder temperatures.
High cylinder temperatures can cause a high coolant temperature.
   
Restriction
   
Result: The exhaust restriction measures OK.
Proceed to the next step.
Result: The exhaust restriction measurement is NOT OK.
Repair: Determine the reason for high exhaust restriction and repair.
If the problem is not resolved, proceed to the next step.
   
6. Check for Engine Overload
A. Determine if
