Lockup clutch solenoid valve
The location for the lockup clutch solenoid valve is on the torque converter lockup clutch valve that is mounted to the torque converter housing.

Schematic of the Modulating Valve (Lockup Clutch)
Note: The approximate coil resistance of the solenoid is 8 ohms at 20 °C (68.0 °F).This diagnostic code is associated with the Modulating Valve (Lockup Clutch). The FMI 06 diagnostic code means that the ECM has determined that the current of the solenoid is above normal. The possible causes of this diagnostic code are listed below:
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: Each connector contact should withstand 45 N (10 lb) of pull. Each wire should remain in the connector body. This test checks whether the wire was properly crimped in the contact and whether the contact was properly inserted into the connector. 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:The CID 0709 FMI 06 diagnostic code changes to a CID 0709 FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The CID 0709 FMI 06 diagnostic code changes to a CID 0709 FMI 05 diagnostic code 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 - The CID 0709 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 J1-59 (wire 705-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.
