Typical exampleTest Step 1. Check for Connector Damage.
Turn the circuit breaker CB-8 to the OFF position.
Thoroughly inspect the ECM connector J1/P1. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and pinch points.Expected Result:The connectors and wiring should be free of the following problems: damage, corrosion, abrasion and incorrect attachment.Results:
OK - The wiring and connectors are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring need repair.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Stop.Test Step 2. Check for "LOGGED" Diagnostic Codes.
Turn the circuit breaker CB-8 to the OFF position.
Connect the Caterpillar Electronic Technician (ET).
Turn the circuit breaker CB-8 to the ON position.
Observe the display diagnostics screen on the Cat ET.Expected Result:A CID-FMI 1-05 to 12-05 or 1-06 to 12-06 should not be logged.Results:
OK - There are no logged diagnostic codes. Proceed to test step 3.
Not OK - There are logged diagnostic codes. Proceed to test step 4.Test Step 3. Perform the Injector Solenoid Test.Note: The test verifies that the ECM can fire the solenoids. Do not try to crank the engine during this test. The engine will start and the ECM will terminate the Injector Solenoid Test.
Start the Cat ET.
Turn the circuit breaker CB-8 to the ON position.
Use the diagnostic tests on the Cat ET to initiate the injector solenoid test.
Listen for a click at each valve cover. A black square will appear over the cylinder number when the cylinder is being fired.
Repeat the test a few times. Verify that the ECM is energizing each solenoid.Expected Result:As each solenoid is energized by the ECM, an audible click of the solenoid should be heard. The solenoids will be energized one at a time in the following numerical order: 1-12. There will be momentary delay between each one.Results:
OK - An audible click of the solenoid was heard for each solenoid. Proceed to test step 5.
Not OK - An audible click of the solenoid was not heard for each solenoid. Proceed to test step 4.Test Step 4. Check for an Open Circuit in the Wiring Harness.
This engine uses high voltage to control the fuel injectors.Disconnect electronic fuel injector enable circuit connector to prevent personal injury.Do not come in contact with the fuel injector terminals while the engine is running.
Turn the circuit breaker CB-8 to the OFF position.
Disconnect the ECM connector J2/P2.
Measure the resistance between the solenoid wire pairs at the ECM connector P2.Measure the resistance for SOLENOID 1 at P2-16 and P2-5.Measure the resistance for SOLENOID 2 at P2-40 and P2-11.Measure the resistance for SOLENOID 3 at P2-26 and P2-5.Measure the resistance for SOLENOID 4 at P2-34 and P2-11.Measure the resistance for SOLENOID 5 at P2-32 and P2-17.Measure the resistance for SOLENOID
