Schematic of the "Radiator Fan Speed Viscus" clutch
This diagnostic code is associated with the "Radiator Fan Speed Viscus" clutch. The FMI 05 diagnostic code means that the ECM has determined that an open in the circuit exists. The possible causes of this diagnostic code are listed below:
The energize circuit of the clutch is open.
The return circuit of the clutch is open.
The clutch 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 0362 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.Test Step 1. CHECK THE CLUTCH.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the clutch with the active diagnostic code from the machine harness.
At the machine harness connector for the clutch, place a jumper wire from contact 1 (wire G834-PU(Purple)) to contact 2 (wire H747-BR(Brown)).
Observe the status of the CID 0362 FMI 05 diagnostic code. Expected Result:The CID 0362 FMI 05 diagnostic code remains active. Results:
YES - The diagnostic code remains active. The jumper wire does not affect the diagnostic code. Proceed to Test Step 2.
NO - The diagnostic is no longer active. The clutch has failed.Repair: The clutch has failed. Repeat this Test Step "CHECK THE CLUTCH" in order to verify the clutch failure. Replace the clutch. Verify that the new clutch corrects the problem.STOPTest Step 2. CHECK THE HARNESS FOR AN OPEN.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector(s) from the Machine ECM.
The jumper wire that was installed in the previous Test Step remains in place.
At the machine harness connector, measure the resistance from signal contact J2-24 (wire G834-PU(Purple)) to contact J2-22 (wire H747-BR(Brown)). Expected Result:The resistance is less than 5 ohms.Results:
OK - The resistance is less than 5 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - The resistance is greater than 5 ohms. The resistance measurement is not correct. There is an open circuit in the machine harness.Repair: The open is in wire G834-PU(Purple) or in wire H747-BR(Brown) of the machine harness. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts of the harness connectors. 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 0362 FMI 05 diagnostic code. Expected Result:The CID 0362 FMI 05 diagnostic code is active. Results:
YES - The CID 0362 FMI 05 diagnostic code 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
