Schematic of the Hydraulic Modulation SolenoidThis diagnostic code is associated with the hydraulic modulation solenoid. The FMI 03 means that the ECM has determined that the voltage of the solenoid circuit is above normal.Some possible causes of the diagnostic code are listed:
The solenoid has failed.
The energize circuit of the solenoid is shorted to the +battery circuit.
The ECM has failed. This is unlikely.System Response:When the CID 2256 FMI 03 diagnostic code is active, the machine response will be:
The warning indicator on the Monitor will illuminate.
The hydraulic modulation function will be disabled.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 2256 FMI 03 is active before performing this procedure.Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO THE +BATTERY CIRCUIT
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the solenoid. Disconnect the machine harness connectors J-1 and J-2 from the ECM.
At the machine harness ECM connector J2, measure the resistance from contact J2-25 (wire E711-OR) to all J-1 and J2 contacts that are connected to +battery. The J-1 contact is J1-58. The J2 contacts are: J2-1, J2-23, J2-47, J2-57 and J2-70.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 J2-25 (wire E711-OR) and the circuit that has a low resistance measurement.Repair: Repair the machine harness or replace the machine harness. Stop.Test Step 2. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE
Inspect the contacts of the harness connectors that are used in the solenoid circuit. Ensure that the contacts are secure. Clean all of the contacts in 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 2256 FMI 03 is active.Expected Result:The CID 2256 FMI 03 is active.Results:
YES - The CID 2256 FMI 03 is active.Repair: Replace the hydraulic modulation solenoid. After solenoid replacement, repeat this Test Step again. If the diagnostic code is still active, the ECM may be faulty. 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 (ECM) - Replace". Stop.
NO - The CID 2256 FMI 03 is not active. The problem does not exist at this time.Repair: The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation. Stop.
