Schematic of the Auxiliary Valve #1 Port B Solenoid (Ripper/Plow Lower Solenoid) (70 pin ECM connection)This diagnostic code is associated with the Auxiliary Valve #1 Port B Solenoid (Ripper/Plow Lower Solenoid). The FMI 06 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:
The energize circuit of the solenoid is shorted to ground.
The solenoid has failed.
The ECM has failed. This is unlikely.Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure and in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure.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 06 is active before performing this procedure.Note: Use a Digital Multimeter for the measurements in this procedure.System Response:A level 1 warning will be generated. 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.
Observe the status of the diagnostic code.Expected Result:CID 2211 FMI 06 changes to CID 2211 FMI 05 when the solenoid is disconnected. Results:
YES - CID 2211 FMI 06 changes to CID 2211 FMI 05 when the solenoid is disconnected. The circuit is correct. Repair: The solenoid has failed. Replace the solenoid. Verify that the new solenoid corrects the problem.STOP
NO - The CID 2211 FMI 06 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 (wire J914-PU) 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 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 the signal contact (wire J914-PU) 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. Check the wires for damage to the insulation that is caused by excessive heat, corrosion, or chafing.
