Information:
System Operation Description:The engine has Fuel Injectors that are mechanically actuated and electronically energized. The Electronic Control Module (ECM) sends a 105 volt pulse to each injector solenoid. The pulse is sent at the proper time and at the correct duration for a given engine load and speed. The solenoid is mounted on top of the fuel injector body. The 105 volt pulse can be individually cut out to aid in troubleshooting misfire problems.If an open is detected in the solenoid circuit, a diagnostic code of CID FMI 1-05 to 12-05 is generated. The ECM continues to try to fire the injector. If a short is detected, a diagnostic code of CID FMI 1-06 to 12-06 is generated. The ECM will disable the solenoid circuit. The ECM will then enable the solenoid. If the short circuit remains this sequence of events will be repeated until the problem is corrected.

Test Step 1. Check for Connector Damage.
Turn the engine control 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:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring should be free of corrosion, abrasion or pinch points.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.STOPTest Step 2. Check for "LOGGED" Diagnostic Codes.
Turn the engine control to the OFF position.
Start the Caterpillar Electronic Technician (ET).
Turn the engine control 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 engine control 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
