Troubleshooting Test Steps    Values    Results    
1. Inspect the Electrical Connectors and the Wiring
A. Set the engine control switch to the OFF position. Remove the electrical power from the engine.
B. Thoroughly inspect the condition of connectors (1) , (2) , (3) , and (5) . Check circuit breaker (4) for the ECM for good repair. Ensure that the breaker has not been tripped. Refer to Testing and Adjusting, "Electrical Connectors - Inspect".
C. Check the torque of the fasteners for each of the ECM connectors and of the engine interface connector. Refer to Testing and Adjusting, "Electrical Connectors - Inspect" for the correct torque values.
D. Check the harness and the wiring for abrasion and for pinch points from the battery to the ECM panel. Check that the fuses for the circuit are not blown.
   
Damaged Connector or wiring    
Result: The connectors, wiring, and the circuit breaker appear to be OK.
Proceed to Test Step 2.
Result: The connectors, wiring, or the circuit breaker are not OK.
Repair the problem. Replace parts, if necessary. Verify that the repair has eliminated the original problem.
   
2. Check for Diagnostic Codes that are Logged
A. Connect the Caterpillar Electronic Technician (ET) to the service tool connector.
B. Restore the electrical power to the engine. Set the engine control switch to the STOP position.
C. Look for a 5419-2, 5419-7, 5419-12, or 5419-13 diagnostic code that is logged.
D. Remove the electrical power from the engine. Set the engine control switch to the OFF position.
   
Logged Diagnostic codes    
Result: There is a logged 5419-2 code.
If this code has been logged and the 5419-13 code has not become active, a calibration attempt has failed. The actuator was calibrated successfully on the next attempt. The valve assembly may be sticking. Check the valve for dirt and debris. If necessary, clean the valve assembly.
Result: There is a logged 5419-7 or 5419-13 code.
Ensure that the ambient temperature around the actuator and valve assembly is above -40° C (-40° F). If the engine is being operated in colder ambient temperatures, take the appropriate measures that will increase the ambient temperature around the engine. If the ambient temperature is OK, use the battery disconnect switch to
