WASHER-COPPER 2431942 - Caterpillar

Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes. Check Caterpillar Electronic Technician (ET) for any associated codes that are listed in Table 1. Troubleshoot any active codes before continuing with this procedure.

Note: The procedures have been listed in order of probability. Complete the procedures in order.Note: If the problem only occurs under certain conditions, test the engine under those conditions. Examples of certain conditions are high engine speed, full load, and engine operating temperature. Troubleshooting the symptoms under other conditions can give misleading results.

Troubleshooting Test Steps     Values     Results    
1. Engine Derate or Active Codes
A. Certain diagnostic codes and/or event codes may cause poor performance. Refer to the histogram information for engine derates in Cat ET. Check for the following histograms:
1. High Exhaust Temperature Prevention Derate Time Histogram
2. High Turbo Speed Prevention Derate Time Histogram
B. If the histograms contain derates and no diagnostic codes are present, then the engine is operating normally. The following list contains conditions that can cause derates:
1. Elevated altitude
2. Elevated inlet air temperature
3. Elevated ambient temperature
   
Engine Derate or Active Codes     Result: A diagnostic code is present.
Repair: Troubleshoot the code and then reset the histogram.
Result: A diagnostic code is not present.
Proceed to Test Step 2.    
2. Incorrect Parameters
A. Use Cat ET to verify that the correct parameters are being used. Refer to Troubleshooting, "Configuration Parameters" for additional information.
   
Parameters     Result: The parameters are correct.
Proceed to Test Step 3.
Result: The parameters are not correct.
Repair: Input the correct parameters. Refer to Troubleshooting, "Configuration Parameters" for additional information.
   
3. Throttle Signal
A. Monitor the status for "Throttle Position" on Cat ET. Verify that the status for "Throttle Position" is stable and that the engine is able to reach high idle speed.
   
Throttle Signal     Result: The throttle signal is stable.
Proceed to Test Step 4.
Result: The throttle signal is not stable.
Repair: Make the necessary repairs, Refer to the appropriate circuit test.
   
4. Restriction in the Air Inlet and Exhaust System
A. Observe the check engine lamp. Check for an air filter restriction indicator. Replace any 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 no restrictions in the air inlet or exhaust system.
Proceed to Test Step 5.
Result: There are restrictions in the air inlet or exhaust system.
Repair: Make the necessary repairs, Refer to Systems Operation/Testing and Adjusting, "Air Inlet and Exhaust System - Inspect" for additional information.
   
5. Check the Fuel System
Refer to Systems Operation/Testing and Adjusting, "Fuel System" for additional information.
A. Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only.
B. Ensure that the vent in the fuel cap is
