Troubleshooting Test Steps Values Results
1. Check the Operation of the Air Shutoff
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.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: There are no active codes.
Proceed to Test Step 3.
Result: There are active codes.
Repair: Troubleshoot any active codes before continuing with this procedure.
3. Check the Electrical Connectors and Wiring
A. Refer to Troubleshooting , Electrical Connectors - Inspect.
Connectors
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.
1. Perform the "Wiggle Test" on Cat ET.
4. Check for an Unstable Fuel Supply
If there is an immediate engine shutdown, troubleshoot the electrical connectors before proceeding with this procedure.
A. Inspect the fuel system. Refer to 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. Refer to Testing and Adjusting , Fuel Quality - Test for the testing procedure.
C. Check the filtered fuel pressure while the engine is being cranked.
Fuel
Result: The fuel quality is acceptable.
Proceed to Test Step 5.
Result: There is a problem with the fuel quality.
Repair: Replace the fuel. Verify that the repair eliminated the problem.
5. Check the Electrical Connections Supply Power
A. Check the power and ground connections to the ECM. Refer to Troubleshooting, "Electrical Power Supply - Test".
Electrical connectors
Result: The electrical connections are in good condition.
Proceed to Test Step 6.
Result: There is a problem with the electrical connections.
Repair: Repair or replace the damaged connectors.
If the repair does not eliminate the problem, proceed to Test Step 6.
6. Check the Switches for Proper Operation
A. Check the keyswitch input to the ECM.
B. Check any engine shutdown switches and associated wiring.
Switches
Result: The shutdown switches and wiring are working properly.
Proceed to Test Step 7.
Result: There is a problem with a shutdown switch and/or wiring.
Repair: Make the necessary repairs.
If the repair does not eliminate the problem, proceed to Test Step 7.
7. Check the Circuit Protection Circuit
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 not tripped.
Proceed to Test Step 8.
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.
8. Check the Engine Speed/Timing Circuit
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"
