Troubleshooting Test Steps Values Results
1. Check the Operation of the Air Shutoff System
Air Shutoff
Result: The air shutoff system is operating properly.
Proceed to Test Step 2.
Result: The air shutoff system is not operating properly.
Repair: Repair the air shutoff system. Refer to Troubleshooting, "Air Shutoff - Test" for troubleshooting information.
2. Check for Codes
A. Certain event codes may cause an engine shutdown. Connect Cat® Electronic Technician (ET) and check for active codes and for logged codes.
B. Using Cat ET, check for associated codes. Refer to Table 1
Codes
Result: There are no associated diagnostic trouble codes active or logged.
Proceed to Test Step 3.
Result: There are associated codes.
Repair: Troubleshoot any associated codes before continuing with this procedure.
3. Inspect the Electrical Connectors for the ECM
A. Check for the correct installation of the ECM J1/P1 and the J2/P2 connectors. Check for correct installation of the fuel injector connectors.
Electrical Connectors and Wiring
Result: There are no suspect connectors.
Proceed to Test Step 4.
Result: There are suspect connectors.
Repair: Repair connectors that are suspect or replace connectors that are suspect.
Perform the "Wiggle Test" on Cat® ET.
4. Check for an Unstable Fuel Supply
A. Inspect the fuel system. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
Note: Cold weather adversely affects the characteristics of the fuel. Refer to the engine Operation and Maintenance Manual for information on improving the characteristics of the fuel during cold-weather operation.
B. Check fuel quality. Check the fuel tank for debris or foreign objects which may block the fuel supply.
C. Check the filtered fuel pressure while the engine is being cranked.
Fuel
Result: The fuel quality is OK.
Proceed to Test Step 5.
Result: The fuel quality is not OK.
Repair: Replace the fuel. Verify that the repair eliminated the problem.
5. Check the Electrical Connections for the ECM
A. Check the power and ground connections to the ECM. Refer to Troubleshooting, "Electrical Power Supply - Test".
Electrical Connectors
Result: The electrical connections are OK.
Proceed to Test Step 6.
Result: The electrical connections are not OK.
Repair: Repair or replace the damaged connectors. Verify that the repair eliminated the problem.
6. Check the Keyswitch Input for the ECM
C. Check any engine shutdown switches and associated wiring.
Keyswitch Input
Result: The shutdown switches and wiring are OK.
Proceed to Test Step 7.
Result: The shutdown switches and wiring are not OK.
Repair: Make the necessary repairs, Verify that the repair eliminated the problem.
7. Inspect the Circuit Protection System
A. Inspect the wires and connectors to all circuit protection for the engine.
B. Check the device for circuit protection.
Circuit Protection
Result The circuit protection device is tripped.
Repair: Reset the circuit breakers if the circuit breakers are tripped. If necessary, replace fuses (if equipped). Prior to returning the engine to service, determine the condition that caused the circuit breaker to trip. Make the necessary repairs.
Result The circuit protection device is not tripped.
Proceed to Test Step 8.
8. Check the Connectors for Engine Speed/Timing
A. Thoroughly inspect the connectors for the engine speed/timing sensors.
B. Crank the engine, if the engine starts and no speed timing codes are logged, the speed timing circuit is operating properly.
Speed/Timing
Result: The Speed/Timing sensor circuit is not operating properly.
Repair: Make the necessary repairs, Verify that the repair eliminated the problem. Refer to Troubleshooting, "Speed/Timing `- Test"
