Diagnostic Codes, Event Codes and Derates
Certain diagnostic codes and/or event codes may cause poor performance. Connect Caterpillar Electronic Technician (ET) and check for active codes and/or logged codes. Wait at least 30 seconds in order for any codes to become active. Troubleshoot any codes that are present before continuing with this procedure.Note: Although a sensor's signal may be in the operational range of the sensor, certain failure modes of a sensor may produce an output signal that does not represent an accurate measurement. Use Cat ET to check that the pressures and the temperatures are fluctuating normally. Also check that the values are reasonable for the conditions that are present.Engine Operation
Use Caterpillar Electronic Technician (ET) to check the "Current Totals" for excessive idle time and/or for a high load factor which would be indicative of poor operating habits.Note: Engine operation may also be affected by environmental conditions such as wind and snow.Fuel Quality
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
Do not loosen any high pressure fuel lines when the engine is running. The high pressure in the fuel lines can cause personal injury or death. Wait 60 seconds after the engine has stopped to allow pressure to purge before any service or repair is performed on the engine fuel lines.
Check fuel quality. Refer to Systems Operation/Testing and Adjusting, "Fuel System".Cold weather adversely affects the characteristics of the fuel. Refer to the Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold weather operation.Engine Speed/Timing
Perform a speed/timing sensor calibration. Refer to the calibration procedure Troubleshooting, "Timing - Calibrate".Air Inlet and Exhaust System
Inspect the air filter for a restriction. If the air filter shows signs of being plugged, clean the air filter or replace the air filter.
Check the air inlet and exhaust system for restrictions and/or for leaks. Refer to Systems Operation/Testing and Adjusting.Accessory Equipment
Check all accessory equipment for problems that may create excessive load on the engine. Repair any damaged components or replace any damaged components.
