This diagnostic code is associated with the Air Conditioner Compressor Clutch Solenoid. The FMI 06 code means that the Machine ECM has determined that the current of the solenoid is above normal.
The possible causes of this diagnostic code are listed below:
- The energize circuit of the solenoid is shorted to ground.
- The solenoid has failed.
- The ECM has failed. ECM failure 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 of the connections in the circuit are clean and secure. 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 2671 FMI 06 is active before performing this procedure.
Note: Use a digital multimeter for the measurements in this procedure.
Test Step 1. CHECK THE SOLENOID
- Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
- Observe the status of the diagnostic code.
- Disconnect the solenoid with the active diagnostic code from the machine harness.
Expected Result:
The FMI 06 changes to FMI 05 after the solenoid is disconnected.
Results:
- YES - The FMI 06 changes to FMI 05 after the solenoid is disconnected. The circuit is correct.
Repair: The solenoid has failed. Replace the solenoid. Verify that the new solenoid has corrected the problem.
STOP
- NO - The 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 connectors from the Machine ECM.
- At the J2 machine harness connector, measure the resistance from the signal contact J2-2 (wire E554-PK) 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 J2-2 (wire E554-PK) and the circuit with the low resistance measurement.
Repair: Repair the machine harness or replace the machine harness.
STOP
Test Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS
- Inspect the harness connectors. Clean the contacts of the harness connectors and check the wires for damage to the insulation that is caused by excessive heat, corrosion, or chafing. Refer to Troubleshooting, "Electrical Connector - Inspect " in this manual.
- Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit.
- Reconnect all harness connectors in order to make sure that the connectors are fully seated. Also, make sure that the clips for each connector are fastened completely.
- Turn the disconnect switch and the key start switch to the ON position.
- Operate the machine.
- Determine if the diagnostic code is active.
Expected Result:
The diagnostic code is active.
Results:
- YES - The diagnostic code is active. The problem has not been corrected.
Repair: Check the circuit again. ECM failure is unlikely. Perform this procedure again.
Prior to replacing an ECM, contact your dealer Technical Communicator (TC) for possible consultation with AVSpare. This consultation may greatly reduce repair time.
If the ECM requires replacement, refer to Troubleshooting, "Electronic Control Module (ECM) - Replace" in this manual.STOP
- NO - The diagnostic code is not active. The initial diagnostic code was probably caused by a poor electrical connection or short at the harness connector that was disconnected and reconnected. The problem does not exist at this time. Resume normal machine operationSTOP
