Connections of the ripper lower solenoid (70 pin ECM connection)This diagnostic code is associated with solenoid "B" on valve 1. The FMI 05 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 solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The valve 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 2211 FMI 05 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Note: Check the configuration of your machine for the number of implement electronic control modules. The following table lists some of the configurations that are available:

Machines with one Electronic Implement Control    
Electronic Implement Control 2     Fourth Valve, Ripper, or Winch

Machines with two Electronic Implement Controls    
Electronic Implement Control 2     Fourth Valve or Ripper    
Electronic Implement Control 3     Winch    Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
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 to contact 2.
Observe the status of the diagnostic code.Expected Result:The diagnostic code is active. Then, the diagnostic code changes from "FMI 05" to "FMI 06" as the jumper wire is installed.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NO - The diagnostic is no longer active.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 solenoid has failed.Repair: The solenoid has failed. Replace the solenoid. Verify that the new solenoid 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 valve ECM.
The jumper wire that was installed in the previous Test Step remains in place.
At the machine harness connector for the valve ECM, measure the resistance from the contact for the supply wire to the contact for the ground wire.Expected Result:The resistance is less than 5.0 ohms.Results:
OK - The resistance is less than 5.0 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.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE ENERGIZED SIDE OF THE CIRCUIT FOR A SHORT TO GROUND.
Remove the jumper wire from the previous step.
The key start and the disconnect switch remain in the OFF position.
At the machine harness connector, measure the resistance from the signal contact (wire J914-PU) to all contacts that are used in the machine harness connectors for the
