Schematic of the Creeper Control Rocker Switch(Switch is shown in OFF (Down) position)This diagnostic code is associated with the Creeper Control Rocker Switch. The switch is connected to two inputs of the ECM. One contact is normally open. The other contact is normally closed. Wire F763-WH is open and wire F764-GN is closed, when the Creeper control switch is in the OFF position. Wire F764-GN is open and wire F763-WH is closed, when the Creeper control switch is in the ON position. Refer to table 1.
Status of the Creeper Control Switch
Mode    Switch Position    F764-GN Circuit
Contact 1    F763-WH Circuit
OFF     Down     Closed     Open
ON     Up     Open     Closed    This FMI 03 means that the ECM has determined that both contacts 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 2669 FMI 03 is active before performing this procedure.System Response:The action lamp is on. If the diagnostic occurs during machine operation, the last known value will be saved. If the diagnostic is present at power up, the machine will default to creep mode OFF.Test Step 1. CHECK THE GROUND CIRCUIT OF THE SWITCH IN THE HARNESS
Disconnect the negative battery cable and turn the key start switch to the OFF position.
Disconnect the machine harness connector(s) from the ECM.
Measure the resistance from Frame Ground of the machine to contact 2 and contact 7 (wire 200-BK) .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 machine harness.STOPTest Step 2. CHECK THE SWITCH CIRCUITS FOR A SHORT TO THE +BATTERY CIRCUIT
The machine harness connector(s) remains disconnected from the ECM.
The key start switch remains in the OFF position.
Disconnect the Creeper Control Switch at the connector to the machine harness.
