Solenoids are 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. As a result the valve is opened. 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.

⁽¹⁾	This multimeter can use an RS232C cable to connect to a Laptop computer or Dataview tool gp for troubleshooting.

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 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 this diagnostic code is active before performing a troubleshooting procedure.

Identify the active FMI code associated with the components.
Determine which code is present and use the list below to determine which procedure to follow.

FMI 3 diagnostic code, proceed to "FMI 3".
FMI 5 diagnostic code, proceed to "FMI 5".
FMI 6 diagnostic code, proceed to "FMI 6".
FMI 13 diagnostic code, proceed to "FMI 13".

Check The Machine Harness For A Short
Troubleshooting Test Steps	Values	Results
1. The start switch and the disconnect switch remain in the OFF position. 2. Disconnect the harness connector from the solenoid. 3. Disconnect the ECM machine harness connectors. 4. Measure the resistance between the solenoid signal contact and all the contacts that are used in the ECM.	Each reading is greater than 5K Ω.	Result: All resistance readings are greater than 5K Ω. Proceed to "Check If The Diagnostic Code Remains" Table 5. Result: One or more readings are less than 5 Ω. Repair: A short exists between the signal contact and the circuit with the low resistance. Repair or replace the machine harness. Note: A resistance that is greater than 5 Ω but less than 5K Ω would indicate a loose connection or a corroded connection in the circuit. A resistance measurement that is greater than 5K Ω would indicate an open in the circuit. Proceed to "Check If The Diagnostic Code Remains" Table 5.

Troubleshooting Test Steps	Values	Results
1. Reconnect all harness connectors. Return machine to normal operating condition. 2. Turn the start switch and the disconnect switch ON. 3. Clear all diagnostic codes. 4. Operate the machine. 5. Stop the machine and engage the safety. 6. Check if the diagnostic code is active.	The diagnostic code is no longer present.	Result: The diagnostic code does not exist currently.
