Schematic of the "Boom Cylinder Extend Limit" Solenoid
This diagnostic code is associated with the "Boom Cylinder Extend Limit" Solenoid. The FMI 03 diagnostic code means the Machine ECM has determined that the voltage of the solenoid circuit is above normal.Conditions that can cause this diagnostic code are listed below:
The energize circuit of the solenoid is shorted to another voltage source.
The Backup switch may have failed.
The ECM has failed. This situation is unlikely.Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all of the connections in the circuit are clean, secure, and in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Note: The resistance of the solenoid coil should be 8.7 .4 ohms at 25 °C (77.0 °F).Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT
Turn the key start switch and the disconnect switch OFF.
Disconnect the machine harness connector from the solenoid. Disconnect the machine harness connectors J1 and J2 from the Machine ECM.
At the harness connector J1, measure the resistance from contact J2-12 (wire K950-YL(Yellow)) to all J1 and J2 contacts on the ECM. Expected Result:Each resistance measurement is greater than 5000 ohms. Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between wire K950-YL(Yellow) and the circuit that has a low resistance measurement. Repair: For information on testing for short circuits and finding short circuits, refer to Testing and Adjusting, "Wiring Harness (Short Circuit) - Test". Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE OPERATION OF THE BACKUP SWITCHThe disconnect switch and the key start switch remain OFF.
