Schematic of the Switch (Ride Control)This diagnostic code is associated with the Switch (Ride Control). The switch is connected to two inputs of the ECM. The inputs are "Normally Open" and "Normally Closed". One of the inputs is open and the other input is grounded during proper operation. Refer to table 1.

ON     Up     Open     Closed    
OFF     Center     Closed     Closed    
AUTO     Down     Closed     Open    The FMI 04 means that the ECM has determined that the "Normally Open" and "Normally Closed" circuits are grounded.Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected.Ensure that the diagnostic code of CID 0367 FMI 04 is active before performing this procedure.System Response:When this diagnostic code occurs, the ride control function is disabled.Test Step 1. CHECK THE SWITCH
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the switch.
Turn the key start switch and the disconnect switch to the ON position.Expected Result:The CID 0367 FMI 04 has been replaced by CID 0367 FMI 03.Results:
OK - The CID 0367 FMI 04 has been replaced by CID 0367 FMI 03. The machine harness and the ECM are correct. Proceed to Test Step 3.
NOT OK - The CID 0367 FMI 04 is still active. Proceed to Test Step 2.Test Step 2. CHECK THE HARNESS
Turn the disconnect switch and the key start switch to the OFF position.
The machine harness remains disconnected from the switch.
Disconnect the machine harness connector(s) from the ECM.
Measure the resistance between contacts J1-22 (wire G767-WH) and J1-21 (wire G766-GN) of the machine harness to all the contacts that are used in machine harness connectors for the ECM.Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
YES - Each resistance measurement is greater than 5000 ohms. The ECM has failed.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the cause of the diagnostic code is not found, replace the ECM. See Testing And Adjusting, "Electronic Control Module (ECM) - Replace". Stop.
NO - One or more of the resistance measurements are less than 5 ohms. The harness has failed. The short is between J1-22 (wire G767-WH) and the circuit with the lowest resistance or the short is between J1-21 (wire G766-GN) and the circuit with the lowest resistance. Repair: Repair the wiring harness or replace the wiring harness. Stop.Test Step 3. CHECK THE OPERATION OF THE SWITCH
The machine harness remains disconnected from the switch.
Connect one lead from a multimeter to contact2 (wire 202-BK) of the harness connector for the switch.
Connect the other lead from a multimeter to contact 4 (wire G767-WH) of the harness connector for the switch.
Measure the resistance between contact 2 (wire 202-BK) and contact
