Boom Float Solenoid connectionsThis diagnostic code is associated with the "Boom Float" Solenoid. The FMI 05 diagnostic code means that the Machine ECM has determined that the current of the solenoid circuit is below normal. The Boom Float solenoid is connected to the switch panel. The switch panel communicates voltage information to the Machine ECM via the CAN B data link.The Boom Float Solenoid is a 24 VDC solenoid that is controlled by the Machine ECM ON/OFF driver output via the CAN B data link. The solenoid is energized by the Soft Switch Panel when the Boom Float UP/DOWN mode is selected by the operator. This solenoid can be overridden in Cat ET.Conditions that could cause this diagnostic code are listed below:
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The Machine ECM has failed. This situation is unlikely. Note: 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 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.Test Step 1. CHECK THE SOLENOID
Disconnect the solenoid from
