Schematic of the "Boom Cylinder Extend Limit" SolenoidThis diagnostic code is associated with the "Boom Cylinder Extend Limit" solenoid. An FMI 05 diagnostic code means the machine ECM has determined the current of the solenoid is below normal. For machines equipped with the E-Fence feature, reference Troubleshooting, "E-Ceiling and Cab Avoidance - Troubleshoot"Possible causes for this diagnostic code are:
The solenoid has failed.
An open wire in the solenoid harness circuits.
The "Back Up" switch has failed.
The ECM may have failed, but is unlikely.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. Ensure that the diagnostic code of CID 2420 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.Note: Poor connections are often the cause of a problem in an electrical circuit. Before performing this procedure, inspect the harness connectors that are involved in the circuit. Verify that all the connections in the circuit are clean, secure, and in good condition. If a problem is found with any of the circuit connections: correct the problem and verify that this diagnostic code is still active, before performing this procedure. Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the "Boom Cylinder Extend Limit" solenoid from the machine harness.
At the harness connector for the solenoid, place a jumper wire from contact 1 (wire K950-YL) to contact 2 (wire K952-BR).
Observe the status of the CID 2420 FMI 05 diagnostic code.Expected Result:The CID 2420 FMI 05 diagnostic code remains active. Results:
YES - The CID 2420 FMI 05 diagnostic code remains active. The jumper wire does not affect the diagnostic code. Proceed to Test Step 2.
NO - The CID 2420 FMI 05 diagnostic code is no longer active, and has been replaced by an active CID 2420 FMI 06 diagnostic code. The harness is correct, and the ECM is correct. Repair: The solenoid has failed. Repeat this Test Step "CHECK THE SOLENOID" to verify the solenoid failure. Replace the solenoid. Verify that the new solenoid corrects the problem.STOPTest Step 2. CHECK THE SOLENOID CIRCUITS FOR AN OPEN.
Turn the key start switch and the disconnect switch to the OFF position.
Set the "Back Up" switch to the OFF position.
Disconnect the J1 and the J2 machine harness connector from the machine ECM.
The jumper wire that was installed in the previous Test Step remains in place.
At the ECM J2 harness connector, measure the resistance from signal contact J2-12 (wire K950-YL) to signal contact J2-35 (wire M739-YL), the solenoid PRV Return in the ECM J2 connector.
Set the "Back Up" switch to the ON position.
At the ECM J2 harness connector, measure the resistance from signal contact J2-12 (wire K950-YL) to signal contact J1-02
