Schematic of the Boom Up Limit solenoid circuitThis diagnostic code is associated with the Boom Up Limit solenoid. An FMI 03 diagnostic code indicates that the machine ECM has determined the voltage of the solenoid circuit is above 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 energize circuit has shorted to another voltage source.
The ECM may have failed, but is unlikely.Note: When this diagnostic code is activated, verify that there are no other active diagnostic codes for the Boom Up Limit solenoid. Those other active diagnostic codes for the solenoid must be cleared before starting this procedure.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes but clear those diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 2420 FMI 03 is active before performing the following 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. Note: Use the 146-4080 Digital Multimeter for the measurements in 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 03 diagnostic code.Expected Result:The CID 2420 FMI 03 diagnostic code remains active. Results:
YES - The CID 2420 FMI 03 diagnostic code remains active. The jumper wire does not affect the diagnostic code.
