The solenoid is used to shutoff, release, distribute, or mix fluids on the machine. Generally, multiple solenoids are located together on a manifold. The solenoid converts electrical energy into magnetic energy, moving a spool located inside the housing of the valve. A spring is used to hold the spool in position until the solenoid is energized.

The magnetic force that acts on the valve spool is created when a coil inside the solenoid is energized.

Possible causes for an FMI 3 Diagnostic code are:

  • The solenoid has failed.

  • The energize circuit of the solenoid is shorted to another voltage source.

  • The ECM has failed. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 5 Diagnostic code 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. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 6 Diagnostic code are:

  • The energize circuit of the solenoid is shorted to a ground source.

  • The solenoid has failed.

  • The ECM has failed. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 13 Diagnostic code are:

  • The ECM detects a solenoid that needs calibration.

( 2 ) Diagnostic Codes for components that are connected to the Implement ECM 3 are communicated to the Implement ECM 1 via CAN Data Link.

The solenoid is used to shutoff, release, distribute, or mix fluids on the machine. Generally, multiple solenoids are located together on a manifold. The solenoid converts electrical energy into magnetic energy, moving a spool located inside the housing of the valve. A spring is used to hold the spool in position until the solenoid is energized.

The magnetic force that acts on the valve spool is created when a coil inside the solenoid is energized.

Possible causes for an FMI 3 Diagnostic code are:

  • The solenoid has failed.

  • The energize circuit of the solenoid is shorted to another voltage source.

  • The ECM has failed. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 5 Diagnostic code 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. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 6 Diagnostic code are:

  • The energize circuit of the solenoid is shorted to a ground source.

  • The solenoid has failed.

  • The ECM has failed. A failure of the Transmission/ Chassis ECM is unlikely.

Possible causes for an FMI 13 Diagnostic code are:

  • The ECM detects a solenoid that needs calibration.

Implement ECM 2 solenoid connections

Note: The diagrams above are simplified schematics of the Implement ECM 2 connections. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of Electrical Schematic, UENR3921 for the complete schematic.

Diagnostic Trouble Code Procedure

Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this 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. Check the wiring harness for pinch points or abrasions. Look for and repair areas that indicate wires are exposed. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure.

Note: Ensure that all safety information, warnings, and instructions are read and understood before any operation or procedures are performed. Perform the following safety measures before you begin to troubleshoot the machine:

  • Move the machine to a surface that is hard and level.

  • Lower all of the implements to the ground.

  • Toggle the parking brake switch to the ON position.

  • Place chocks in the front of the wheels and behind the wheels.

  • Shut off the engine.

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, that all connections are secure and that all connections are 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.
