Note: The approximate coil resistance of the solenoid is 8 ohms at
This diagnostic code is associated with the Modulating Valve (Lockup Clutch). The FMI 06 means that the ECM has determined that the current of the solenoid is above normal.
The possible causes of this diagnostic code are listed:
- The energize circuit of the solenoid is shorted to ground.
- The solenoid has failed.
- The ECM has failed. This is unlikely.
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 0709 FMI 06 is active before performing this procedure.
Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.

When it is necessary to work under the machine with the body (bed) raised, attach the body (bed) retaining cables to the rear tow points. Install the rear tow point pins through the ends of the retaining cables. Failure to properly secure the body (bed) may result in personal injury or death. |
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:
CID 0709 FMI 06 changes to CID 0709 FMI 05 when the solenoid is disconnected.
Results:
- YES - CID 0709 FMI 06 changes to CID 0709 FMI 05 when the solenoid is disconnected. The circuit is correct.
Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid.
STOP
- NO - CID 0709 FMI 06 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 J2-60 (wire 705-AM44-PK(Pink)) 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 J2-60 (wire 705-AM44-PK(Pink)) and the circuit with the low resistance measurement.
Repair: Repair the machine harness or replace the machine harness.
STOP
Test 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 0709 FMI 06.
Expected Result:
The CID 0709 FMI 06 is active.
Results:
- YES - The CID 0709 FMI 06 is active. The diagnostic code 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 (ECM) - Replace".
STOP
- NO - The CID 0709 FMI 06 is not active. The diagnostic code 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.
