Schematic for "Lower KO Detent" solenoid
This diagnostic code is associated with the "Lower KO Detent" 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 of this diagnostic code are listed below:
The internal windings for the detent coil have low impedance.
The internal windings for the detent coil are shorted.
The signal circuit from the ECM to the "Lower KO Detent" solenoid is shorted to ground.Note: The following test procedure may create other diagnostic codes. Clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 0360 FMI 06 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:The machine response is listed below:The "Lower KO Detent" solenoid cannot be energized resulting in the loss of the lower "kickout" feature. The control is unable to hold the lever in the detent position.Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the key start switch to the ON position. Note: Do not start the engine.
Observe the status of the diagnostic code.
Disconnect the "Lower KO Detent" solenoid from the machine harness. Expected Result:The CID 0360 FMI 06 diagnostic code changes to a "CID 0360 FMI 05"diagnostic code when the solenoid is disconnected.Results:
YES - The CID 0360 FMI 06 diagnostic code changes to a CID 0360 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 0360 FMI 06 diagnostic code remains active. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZER 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 J2-3 (wire H715-PU(Purple)) 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 J2-3 (wire H715-PU(Purple)) 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 0360 FMI 06 diagnostic code. Expected Result:The CID 0360 FMI 06 diagnostic code is active.Results:
YES - The CID 0360 FMI 06 diagnostic code is active. The diagnostic code has not been corrected. The ECM may
