Schematic of the Push Button Switch (Blade Cross Slope Switch)
This diagnostic code is associated with the Push Button Switch (Blade Cross Slope Switch) located on the RH joystick. The switch is connected to two inputs of the ECM. One contact is open and the other contact is grounded during proper operation. This FMI 03 diagnostic code means that the ECM has determined that the normally open contact and the normally closed contact are open.Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear the diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 4784 FMI 03 is active before performing this procedure.Test Step 1. CHECK THE GROUND CIRCUIT OF THE SWITCH IN THE HARNESS.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connectors from the ECM.
Measure the resistance between contact J2-22 (wire H745-BR(Brown)) of the machine harness for the ECM and contact 7 (wire H745-BR(Brown)) at the joystick connector. Expected Result:The resistance is less than 5 ohms. Results:
OK - The resistance is less than 5 ohms. The circuit is correct. Proceed to Test Step 2.
NOT OK - The resistance is greater than 5000 ohms. The circuit is open. The machine harness has failed.Repair: Repair the machine harness or replace the
