Schematic of the "Attachment Valve #3 Retract" Pressure Solenoid
This diagnostic code is associated with the "Attachment Valve #3 Retract" Pressure Solenoid. The FMI 03 diagnostic code means that the ECM has determined that the voltage is above normal.The possible causes of the diagnostic code are listed:
The solenoid has failed.
The solenoid energizer circuit of the modulating valve is shorted to the +battery circuit.
The ECM has failed. This is unlikely.Note: The Machine ECM is equipped with LED indicators that serve as a self-diagnostic check. With the key start switch ON, the following can be determined by the ECM indicator lights: If all of the LED lights are Off, voltage is not being supplied to the Machine ECM. Check for power to the ECM. If the yellow LED is Flashing, a communication error exists on the "CAN" data-link circuit. If the yellow LED is constantly On, the Machine ECM software may be missing / not loaded. If the red LED is Flashing, the Machine ECM has failed and may need replacement. 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. Ensure that the diagnostic code of CID 1598 FMI 03 diagnostic code is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code is active, the ECM will turn off the current to the failed solenoid.Test Step 1. CHECK THE SOLENOID ENERGIZER CIRCUIT FOR A SHORT TO THE +BATTERY CIRCUIT
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connectors from the solenoid and the ECM.
At the machine harness connector for the ECM, measure the resistance from contact J2-41 (wire K862-GY(Grey)) to all contacts that are used in the machine harness connectors for the ECM. Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 2.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between J2-41 (K862-GY(Grey)) and the circuit that has a low resistance measurement.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Determine if the CID 1598 FMI 03 diagnostic code is active. Expected Result:The CID 1598 FMI 03 diagnostic code is active.Results:
YES - The CID 1598 FMI 03 diagnostic code is active. The problem has not been corrected. The ECM may have failed.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the cause of the diagnostic code is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module
