Schematic of the rotary switch (autoshift control)
This diagnostic code is associated with the rotary switch (autoshift control). The rotary switch is connected to two inputs of the ECM. One contact is open and the other contact is grounded during proper operation.The FMI 04 means that the ECM has determined that the circuits are grounded.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 0368 FMI 04 is active before performing this procedure.

Manual Closed Open
Auto Open Closed 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 Expected Result:The CID 0368 FMI 04 has been replaced by CID 0368 FMI 05.Results:
OK - The CID 0368 FMI 04 has been replaced by CID 0368 FMI 05. The machine harness and the ECM are correct. Proceed to Test Step 3.
NOT OK - The CID 0368 FMI 04 is still active. Proceed to Test Step 2.Test Step 2. CHECK THE HARNESS
The machine harness connector remains disconnected from the switch.
The disconnect switch and the key start switch remain in the OFF position.
Disconnect the machine harness connector(s) from the ECM.
At the machine harness connector for the ECM, measure the resistance from connector contact J2-37 (wire 973-BR(Brown)) and connector contact J2-36 (wire 977-YL(Yellow)) of the machine harness to all the contacts that are used in the machine harness connectors for the ECM. Expected Result:Each resistance measurement is greater than 5 ohms.Results:
OK - Each resistance measurement is greater than 5 ohms. The harness is correct. Proceed to Test Step 3.
NO - One or more of the measurements were less than 5 ohms. There is a short in the machine harness.Repair: The short is between wire (973-BR(Brown)) and the circuit with the lowest resistance measurement. The short is between wire (977-YL(Yellow)) and the circuit with the lowest resistance. Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK THE OPERATION OF THE SWITCH
The machine harness remains disconnected from the switch.
Rotate the switch to the MANUAL position.
Connect one lead from a multimeter to connector contact A (wire 202-BK(Black)) of the harness connector for the switch.
Connect the other lead from a multimeter to each of the two connector contacts of the switch.
Measure the resistance between connector contact A (wire 202-BK(Black)) and each connector contact of the switch. Note the resistance at each connector contact.
Rotate the switch to the AUTO position.
Measure the resistance between connector contact A (wire 202-BK(Black)) and each connector contact of the switch. Note the resistance at each connector contact. Expected Result:The resistance from connector contact A to each connector contact of the switch complies with Table 1. A closed contact measures less than 5 ohms. The measure of an
