Schematic of the Hopper Apron Lower (Fold Down) SolenoidThis diagnostic code is associated with the Hopper Apron Lower (Fold Down) Solenoid. The FMI 05 means that the RH Operator ECM has detected that the current for the solenoid circuit is below normal.Note: The RH Operator ECM is located under the RH Operator Platform.Conditions that could cause this diagnostic code to be activated are:
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The 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. System Response:When this diagnostic code is active, the following occurs:
Hopper apron lower is disabled.
Operator station fault lamp is active.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 27 1.4 ohms at 20 °C (68.0 °F).Test Step 1. CHECK THE SOLENOID
Disconnect the machine harness from the solenoid at the Hopper Apron Lower hydraulic valve.
