Schematic for the Lift Linkage Lower Solenoid | |
This diagnostic code is associated with the lift linkage lower solenoid. The FMI 05 means that the ECM has determined that the current for the solenoid is below normal. An open may exist in the circuit for the solenoid.
The possible causes of the diagnostic code are listed:
- The energize circuit of the solenoid is open.
- The return circuit from the solenoid is open. An open in the return circuit could result in an open circuit diagnostic code for some other implement solenoid valves.
- The solenoid has failed.
- The ECM has failed. This is unlikely.
System Response:
The machine response is listed:
- The lift linkage solenoid will turn OFF.
- The blade raise function will be disabled until the diagnostic code is corrected and the levers are centered.
Note: The following test procedure may create other diagnostic codes. Ignore the created diagnostic codes. Clear these diagnostic codes when the original diagnostic code is corrected.
Note: Ensure that the diagnostic code is active and that the diagnostic code indicator is active.
Test Step 1. CHECK THE SOLENOID
- Disconnect the solenoid with the active diagnostic code from the machine harness.
- At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire H714-OR) to contact 2 (wire H716-WH).
- Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
- Observe the status of the CID 0355 FMI 05.
Expected Result:
The CID 0355 FMI 05 diagnostic code remains active.
Results:
- YES - The CID 0355 FMI 05 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- NO - The diagnostic is no longer active.
Repair: The solenoid has failed. Repeat this Test Step "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid. Verify that the new solenoid corrects the problem.
Stop.
Test Step 2. CHECK THE HARNESS
- Turn the disconnect switch to the OFF position.
- Disconnect the machine harness ECM connector J1 from the ECM
- The jumper wire that was installed in the previous test step remains in place.
- At the harness connector for the ECM, measure the resistance between contacts J1-7 (wire H716-WH) and contact J1-4 (wire H714-OR).
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 5000 ohms. The resistance measurement is not correct. There is an open circuit in the machine harness. A resistance measurement that is much greater than 5 ohms but less than 5000 ohms could indicate that one of the connection points is not open but is not a good connection.
Repair: The open or possible bad connection is in wire H714-OR or in wire H716-WH of the machine harness. Repair the machine harness or replace the machine harness.
Stop.
Test Step 3. CHECK THE STATUS OF THE DIAGNOSTIC CODE
- Inspect the contacts of the harness connectors that are used in the solenoid circuit. Ensure that the contacts are secure. Clean all of the contacts in 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 0355 FMI 05.
Expected Result:
The CID 0355 FMI 05 diagnostic code is active.
Results:
- YES - The CID 0355 FMI 05 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. Refer to the full machine electrical system schematic. Ensure that all connections in the solenoid circuit are intact, clean and secure. 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 0355 FMI 05 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 at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.
Stop.
