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 code is active or logged.
Proceed to Test Step 2.
2. Check for High Intake Manifold Temperature
Note: A one degree increase in the intake manifold temperature will increase the exhaust temperature by approximately three degrees.
A. Refer to Troubleshooting, "Intake Manifold Air Temperature Is High" for additional information.
Temperature
Result: The intake manifold temperature is OK.
Proceed to Test Step 3.
Result: The intake manifold temperature is NOT OK.
Repair: Determine the cause of the high inlet air temperature. Repair or replace damaged components.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Valve Lash
Note: The valve lash can affect the performance of the engine.
Valve Lash
Result: The valve lash is OK.
Proceed to Test Step 4.
Result: The valve lash is NOT OK.
Repair: Reset the valve lash. Refer to Testing and Adjusting, "Valve Lash - Adjust" for additional information.
If the problem is not resolved, proceed to Test Step 4.
4. Check for High Exhaust Temperature
A. Refer to Troubleshooting, "Exhaust Temperature Is High" for additional information.
Temperature
Result: The exhaust temperature is OK.
Proceed to Test Step 5.
Result: The exhaust temperature is NOT OK.
Repair: Determine the cause of the high exhaust temperature. Repair or replace damaged exhaust components.
If the problem is not resolved, proceed to Test Step 5.
5. Inspect the Inlet Air System
A. Check the air filter restriction indicator, if equipped. Refer to the Operation and Maintenance Manual for additional information.
B. Measure the inlet air restriction for each turbocharger. Refer to Troubleshooting, "Inlet Air Is Restricted" for additional information.
C. Check the following inlet air system components for leaks:
- Hoses
- Tubes
- Bellows
- Clamps
Inlet Air System
Result: The inlet air system is OK.
Proceed to Test Step 6.
Result: The inlet air system is NOT OK. An imbalance in the system is discovered.
Repair: Repair or replace damaged inlet air system components. Equalize the inlet air restriction for each of the turbochargers.
If the problem is not resolved, proceed to Test Step 6.
6. Inspect the Exhaust System
A. Turn the keyswitch to the "OFF" position.
B. Inspect the following exhaust components:
- Lines
- Hoses
- Bellows
- Clamps
- Exhaust manifolds
Note: Verify that all the bellows have the correct orientation. Ensure that the arrow on the bellows is pointing in the direction of the exhaust flow.
Exhaust System
Result: The exhaust system is OK.
Proceed to Test Step 7.
Result: The exhaust system is NOT OK.
Repair: Repair or replace damaged exhaust components.
If the problem is not resolved, proceed to Test Step 7.
7. Inspect the Air-to-Air Aftercooler (ATAAC)
A. Check the ATAAC for dirt, debris, and/or damage.
B. Check the ATAAC for restrictions and internal blockage.
C. Check the ATAAC lines for leaks and/or damage.
Aftercooler
Result: The aftercooler and lines are OK.
Proceed to Test Step 8.
Result: The aftercooler and lines are NOT OK.
Repair: Clean or replace damaged aftercooler or lines.
If the problem is not resolved, proceed to Test Step 8.
8. Test the Fuel Injectors
Note: Faulty injectors that deliver too much fuel will increase exhaust temperatures.
A. Connect Cat ET.
B. Use Cat ET to perform the following fuel injector tests:
- "Injector Solenoid Test"
- "Cylinder Cutout Test"
Refer to Troubleshooting, "Cat ET Service Features" for additional information.
Fuel Injectors
