Diagnostic Codes and/or Event Codes
Certain diagnostic codes and/or event codes may cause an engine shutdown. Connect Caterpillar Electronic Technician (ET) and check for active codes and for logged codes. Troubleshoot any codes that are present prior to continuing with this procedure.Electrical Connectors
Check for correct installation of the J14/P14 connector for the Electronic Control Module (ECM). Also, thoroughly inspect the connectors for the engine speed/timing sensors. Refer to Troubleshooting, "Electrical Connectors - Inspect".
Inspect the battery wires from the ECM to the battery compartment. Refer to the Schematic for specific wiring information. Inspect the wires and connectors to all circuit protection for the engine. Check the power and ground connections to the ECM. Check any engine shutdown switches and associated wiring. Refer to Troubleshooting, "Electrical Power Supply - Test".Aftermarket Engine Protection Devices
Check any aftermarket engine protection devices for proper operation. These devices usually interrupt power to the ECM.Fuel Supply
Visually check the fuel level in the fuel tank. Do not rely on the fuel gauge only. If necessary, add fuel to the fuel tank. If the engine has been run out of fuel, it will be necessary to purge the air from the fuel system. Refer to Operation and Maintenance Manual for the correct procedure.
Check the fuel lines for the following problems: restrictions, collapsed lines and pinched lines. If problems are found with the fuel lines, repair the lines and/or replace the lines.
Check the fuel tank for debris or foreign objects which may block the fuel supply.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Prime the fuel system if any of the following procedures have been performed:
Replacement of the fuel filters
Service on the low pressure fuel supply circuitNote: Check the fuel system for air. Refer to Systems Operation/Testing and Adjusting for information that is related to checking the fuel system for air.
Check fuel quality. Cold weather adversely affects the characteristics of the fuel. Refer to the engine's Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold weather operation.
Check the filtered fuel pressure while the engine is being cranked. Refer to Systems Operation/Testing and Adjusting for the test procedure and for the correct pressure values. If the fuel pressure is low, replace the fuel filters. Clean the primary filter/water separator of debris. Refer to the Operation and Maintenance Manual for details. If the fuel pressure is still low, check the operation of the fuel pressure regulating valve. Also, check for the proper operation of the fuel transfer pump. Refer to Systems Operation/Testing and Adjusting for test information.Throttle Signal
Monitor the status of the "Throttle Position" on Cat ET. Verify that the status of the "Throttle Position" is stable and that the engine is able to reach high idle speed. If a problem is suspected with the throttle, refer to the appropriate troubleshooting procedure for troubleshooting the throttle signal.Rack Controls
Check the rack solenoid for proper operation. Refer to Troubleshooting, "Fuel Rack Solenoid - Test" for troubleshooting procedures. Refer to Troubleshooting, "Fuel Control - Test" in order to troubleshoot the dynamic rack controls. Also, refer to Troubleshooting, "Sensor Signal (Analog, Active) - Test" for procedures to troubleshoot the Rack Position Sensor.ECM or Personality Module
Check for proper operation of the ECM and the personality module. Refer to Troubleshooting, "ECM - Replace" for the troubleshooting procedures. Also, refer to Troubleshooting, "ECM Software - Install" in order to troubleshoot the personality module.
