Generator Valve Solenoid connectionsThis diagnostic code is associated with the Generator Valve Solenoid. The FMI 06 means that the Implement ECM 2 has detected that the current for the solenoid circuit is above normal.The Generator Solenoid is a 24 VDC solenoid that is controlled by a Implement Control 2 ECM ON/OFF driver output. When the generator is set to installed, the solenoid is energized by the ECM in order to disable the generator. When the generator is selected as the active tool, the ECM will control the solenoid based on the input from the generator enable switch. This solenoid can be overridden in Cat ET.Conditions that can cause this diagnostic code are listed:
The energize circuit of the solenoid is shorted to a ground source.
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.Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the key 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 active FMI 06 diagnostic code changes to a FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The active FMI 06 diagnostic code changes to a FMI 05 diagnostic code when the solenoid is disconnected. The circuit is correct.Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid.STOP
NO - FMI 06 diagnostic code remains active. Disconnecting the solenoid did not affect the status of the diagnostic code. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUNDThe solenoid remains disconnected from the machine harness.
Turn the key switch and the disconnect switch to the OFF position.
Disconnect the machine harness connectors J1 and J2 from the Machine Control ECM and the Implement ECM 2.
At the Implement ECM 2 machine harness connector J2, measure the resistance from the supply contact J2-3 (wire E984-BU) to frame ground. Measure the resistance from the supply contact J2-3 (wire E984-BU) to all of the other contacts that are used in the Machine Control ECM connectors and the Implement ECM 2 connectors.Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The solenoid circuit is not shorted in the machine harness. Proceed to Test Step 3.
NOT OK - One or more of the resistance measurements is less than 5000 ohms.
