The "Fine Swing" solenoid is identified in the photograph by the arrow.
Illustration 2 g02308393
Schematic of the Fine Swing solenoid.This diagnostic code is associated with the fine swing solenoid.This diagnostic code is recorded when the ECM reads the current of the solenoid as being above normal.The possible causes are listed below:
A wire is shorted to ground.
The solenoid has failed.
There is an incorrect attachment code.
The ECM has failed. A failure of the ECM is unlikely.Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.Note: Ensure that CID 0732 FMI 06 for the solenoid is active. 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 machine harness from the solenoid.
Observe the status of the diagnostic code.
Install a jumper wire between contacts 1 and 2 of the machine harness connector.
Observe the status of the diagnostic code.Expected Result:The diagnostic code is active. Then, the diagnostic code changes to FMI 05 as the jumper wire is installed.Results:
NO - The circuit is correct. The solenoid has failed.Repair: Repeat this test "CHECK THE SOLENOID" in order to verify that the solenoid has failed. Replace the solenoid.STOP
YES - The diagnostic code remains active. Proceed to Test Step 2.Test Step 2. CHECK THE SOLENOID CIRCUIT FOR A SHORT TO GROUND.
The machine harness remains disconnected from the solenoid.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the C1, C13, and C2 machine harness connector from the switch panel.
At the C2 machine harness connector for the switch panel, measure the resistance from the solenoid contact C2-6 (wire L973-GN) to all possible sources of ground.Expected Result:Each resistance measurement should be greater than 5000 ohms.Results:
YES - The machine harness is correct. Proceed to Test Step 3.
NO - There is a short in the machine harness.Repair: The short is between the wire for the solenoid signal and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Check if the diagnostic code for the solenoid is active.Expected Result:The diagnostic code is no longer active. Results:
YES - The diagnostic code is no longer active. The diagnostic code does not exist at this time. The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors. Resume normal machine operation. STOP
NO - The diagnostic code has not been corrected.Repair: A failure of the switch panel is unlikely. Exit this procedure and perform this procedure again. Also, recheck if the diagnostic code is active. If the cause of the diagnostic code is not found, replace the switch panel. See Testing
