Schematic of the Counterweight Extend Solenoid CircuitThis diagnostic code is associated with the Counterweight Extend Solenoid. The FMI 05 means the ECM has determined that an open exists in the circuit for the solenoid.The possible causes of this diagnostic code are listed below:
The energized circuit of the solenoid is open.
The energized circuit of the solenoid is shorted to ground.
The return circuit of the solenoid is open.
The return circuit of the solenoid is shorted to ground.
The solenoid has failed.
The ECM has failed. This 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 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 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 2957 FMI 05 is active before performing this procedure.Note: Use a Digital Multimeter for the measurements in this procedure.System Response:A level 1 warning will be generated.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 solenoid with the active diagnostic code from the machine harness.
At the machine harness connector for the solenoid, place a
