Swing Brake Solenoid connectionsThis diagnostic code is associated with the Swing Brake Solenoid. The FMI 03 diagnostic code means that the Machine Control ECM has determined that the voltage of the solenoid circuit is above normal.The Swing Brake Solenoid is controlled by a Machine Control ECM PWM driver output. In order to control the solenoid, the Machine Control ECM will change the current of the PWM output signal. When the solenoid is de-energized, the swing brake is ON. When the solenoid is energized by the Machine Control ECM, the swing brake is OFF.Conditions that can cause this diagnostic code are:
The energize circuit of the solenoid is shorted to another voltage source.
The ECM has failed. This situation 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. Verify that the CID 0374 FMI 03 diagnostic code is active before performing this procedure.Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the solenoid.
Disconnect the machine harness connectors J1 and J2 from the Machine Control ECM.
At the machine harness connector J2 for the Machine Control ECM, measure the resistance from contact J2-3 (wire C995-YL) to all J1 and J2 contacts that are used on the Machine Control ECM connectors.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 2.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between wire C995-YL and the circuit that has a low resistance measurement. Repair: Refer to the Electrical System Schematic of the machine. Examine all of the connectors in circuits for points in the machine harness where the circuits could be shorted. For information on testing for short circuits and finding short circuits, refer to Testing and Adjusting, "Wiring Harness (Short Circuit) - Test". Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE OPERATION OF THE ECMThe disconnect switch and the key start switch remain in the OFF position. The machine harness connectors for the solenoid and the ECM remain disconnected.
At the machine harness connector J1 for the Machine Control ECM, use a 151-6320 Removal Tool to remove the solenoid energize wire C995-YL and socket at contact J2-3 from the harness connector.
Reconnect the machine harness J1 and J2 connectors to the Machine Control ECM.
Turn the disconnect switch and the key start switch to the ON position.
Observe the status of the active CID 0374 FMI 03 diagnostic code.Expected Result:The CID 0374 FMI 03 diagnostic code is no longer active. A CID 0374 FMI 05 diagnostic code is now active.Results:
YES - The CID 0374 FMI 03 diagnostic code is no longer active. A CID 0374 FMI 05 diagnostic code has
