Troubleshooting Test Steps Values Results
1. Check for Active Codes and Logged Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM).
B. Monitor the diagnostic codes on Cat ET. Certain diagnostic codes and/or event codes may cause poor performance.
Note: Wait at least 30 seconds in order for diagnostic codes to become active.
Codes
Result: A code is active or logged.
Repair: Troubleshoot any codes before continuing with this procedure.
Result: A code is not active or logged.
Proceed to Test Step 2.
2. Check for Incorrect Parameters
A. Use Cat ET to verify that the correct engine parameters are being used. Refer to Troubleshooting, "Configuration Parameters" for additional information.
B. Verify that all of the parameters for parasitic loads are correct.
Parameters
Result: The parameters are configured correctly.
Proceed to Test Step 3.
Result: The parameters are not configured correctly.
Repair: Correctly configure the parameters.
If the problem is not resolved, proceed to Test Step 3.
3. Inspect Accessories and/or Parasitic Loads
A. Check all accessory equipment for problems that may create excessive load on the engine.
B. Check for any excess parasitic load on the engine.
Parasitic Loads
Result: There is not an excessive load on the engine.
Proceed to Test Step 4.
Result: There is an excessive load on the engine.
Repair: Diagnose the problem and then repair the problem.
If the problem is not resolved, proceed to Test Step 4.
4. Check for an Incorrect Flash File
A. Verify that the latest flash file is installed in the Electronic Control Module (ECM). Refer to Troubleshooting, "ECM Software - Install" for the proper procedure.
Flash File
Result: The latest flash file is installed in the ECM.
Proceed to Test Step 5.
Result: The latest flash file is not installed in the ECM.
Repair: Install the latest flash file.
If the problem is not resolved, proceed to Test Step 5.
5. Restriction in the Air Inlet and Exhaust System
A. Check the air filter restriction indicator, if equipped. Clean plugged air filters or replace plugged air filters. Refer to the Operation and Maintenance Manual.
B. Check the air inlet and exhaust system for restrictions and/or leaks.
Restrictions
Result: There are restrictions in the air inlet or exhaust system.
Repair: Make the necessary repairs.
Result: There are no restrictions in the air inlet or exhaust system.
Proceed to Test Step 6.
6. Proper Operation of the Supercharger and/or the Turbocharger
A. Inspect the supercharger belt and pulley.
B. Inspect the supercharger clutch operation.
Supercharger and Turbocharger
Result: The supercharger and turbocharger are operating properly.
Proceed to Test Step 7.
Result: The supercharger is not operating properly.
Repair: Repair or replace the supercharger.
Result: The turbocharger is not operating properly.
Repair: Repair or replace the turbocharger.
If the problem is not resolved, proceed to Test Step 7.
7. Inspect the Fuel System
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the fuel supply valve (if equipped) is in the full OPEN position.
C. Inspect the fuel system. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
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. Check the fuel tank for debris or foreign objects which may block the fuel supply.
E. Check the filtered fuel pressure while the engine is being cranked. Refer to Troubleshooting, "Fuel Pressure Is Low" for the proper testing procedure.
Fuel System
Result: The fuel system is operating properly.
Proceed to Test Step 8.
Result: The fuel system is not operating properly.
Repair: Make the necessary repairs.
If the problem is not resolved, proceed to Test Step 8.
8. Test the Fuel Injectors
If service has been performed on the engine fuel system recently, verify that the injector trim files are correct. Use Cat ET to check that the injector trim files are correct for the injectors that are installed on the engine.
A. Perform the "Run-Up Test" on Cat ET in order to determine if all of the injector solenoids are being energized by the ECM.
B. Access the "Cylinder Cutout Test" in the "Diagnostic Tests" under the "Diagnostics" menu.
C. Perform the "Automatic Cylinder Cutout Test" on Cat ET.
Fuel Injector
Result: The test was successful.
Return the unit to service.
Result: The test was not successful.
Repair: Diagnose the problem and then repair the problem.
Reset all active codes and clear all logged codes.
