Schematic for the "Dump Right" solenoid
This diagnostic code is associated with the "Dump Right" solenoid. The FMI 06 diagnostic code means that the ECM has determined that there is a short to ground in the solenoid circuit. The possible causes for this diagnostic code are listed below:
The internal windings for the solenoid have low impedance.
The internal windings for the solenoid are shorted.
The signal circuit from the ECM to the solenoid is shorted to ground.System Response:The machine response is listed below:Since hydraulic flow to the cylinder is supplied by two control valves, the "dump right" function is possible at a reduced rate.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 0595 FMI 06 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Observe the status of the diagnostic code.
Disconnect the solenoid with the active diagnostic code from the machine harness. Expected Result:The CID 0595 FMI 06 diagnostic code changes to a CID 0595 FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The CID 0595 FMI 06 diagnostic code changes to a CID 0595 FMI 05 diagnostic code when the solenoid is disconnected. The circuit is correct.Repair: The solenoid has failed. CHECK THE SOLENOID. Repeat this test in order to verify the solenoid failure. Replace the solenoid.STOP
NO - The CID 0595 FMI 06 diagnostic code remains active. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUND.
Turn the key start switch and the disconnect switch to the OFF position.
The solenoid remains disconnected from the machine harness.
Disconnect the machine harness connector(s) from the ECM.
At the machine harness connector, measure the resistance from the signal contact J1-62 (wire F744-BU(Blue)) 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 3.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between J1-62 (wire F744-BU(Blue)) and the circuit with the low resistance measurement.Repair: Repair the machine harness or replace the machine harness. STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the harness connectors 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.
Check the status of the CID 0595 FMI 06 diagnostic code. Expected Result:The CID 0595 FMI 06 diagnostic code is active. Results:
YES - The CID 0595 FMI 06 diagnostic code is active. The diagnostic code has not been corrected. The ECM may have
