Information:

Possible causes for an FMI 3 Diagnostic code are:
The ground wire is open.
A signal is permanently open.
A short to battery exists in the circuit.
The switch has failed.
The ECM has failed. A failure of the ECM is unlikely.Possible causes for an FMI 4 Diagnostic code are:
A short to ground.
The switch has failed.
The ECM has failed. An ECM failure is unlikely.

Switch Circuits Connections
Note: The diagram above is a simplified schematic of the connections for the switch circuits. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of the Electrical Schematic, UENR3832 for the complete schematic.Diagnostic Trouble Code Procedure
Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure. For sensors powered via the fuse panel, check the condition of the appropriate fuse before beginning the troubleshooting procedure.

2. Check The Signal Circuits For An Open
A. Turn the disconnect switch and the key start switch to the OFF position.
B. Disconnect the J1 machine harness connector from the ECM.
C. At the J1 machine harness connector, measure the resistance from the Normally Open contact to the ground contact on the switch with the switch in the normally open position. The switch is pressed.
D. At the J1 machine harness connector, measure the resistance from the Normally Closed contact to the ground contact on the switch with the switch in the normally closed position. The switch is not pressed.
Open resistance should be greater
