Schematic of the Ride Control Switch
This diagnostic code is associated with the Ride Control Switch. The switch is connected to two inputs of the ECM. When the switch is in the OFF position, the inputs are both open. One of the inputs is grounded during actuation of the switch and the other input remains open.The FMI 04 means that the ECM has determined that both of the 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 367 FMI 04 is active before performing this procedure.System Response:When this diagnostic code occurs, the ride control switch does not function.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 Expected Result:The CID 367 FMI 04 is no longer active.Results:
OK - The CID 367 FMI 04 is no longer active. The machine harness and the ECM are correct. Proceed to Test Step 3.
NOT OK - The CID 367 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 J2-45 (wire E701-PK(Pink)) and J2-46 (wire F748-WH(White)) 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 Troubleshooting, "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 J2-45 (wire E701-PK(Pink)) and the circuit with the lowest resistance or the short is between J2-46 (wire F748-WH(White)) and the circuit with the lowest resistance. Repair: Repair the wiring harness or replace the wiring harness.STOPTest Step 3. CHECK THE OPERATION OF THE SWITCH
The machine harness remains disconnected from the switch. Place the switch in the OFF position.
Connect one lead from a multimeter to contact 2 (wire 202-BK(Black)) of the harness connector for the switch.
Connect the other lead from a multimeter to contact 1 (wire E701-PK(Pink)) of the harness connector for the switch.
Measure the resistance between contact 2 (wire 202-BK(Black)) and contact 1 (wire E701-PK(Pink)) . Note the resistance.
Disconnect the lead from contact 1 (wire E701-PK(Pink)) and connect the lead to contact 3 (wire F748-WH(White)) .
Measure the resistance between contact 2 (wire 202-BK(Black)) and contact 3 (wire F748-WH(White)). Expected Result:Both of the resistance measurements are greater than 5000 ohms.Results:
YES -
