Schematic of the Creeper Control Momentary Switch
(Switch is shown in OFF (Up) position)
This diagnostic code is associated with the Creeper Control Momentary Switch. The switch is connected to the input of the ECM. The contact is normally open. Wire F763-WH(White) to wire 203-BK(Black) are open when the Creeper control switch is in the OFF (up) position. Wire F763-WH(White) to wire 203-BK(Black) are closed (shorted together), when the Creeper control switch is in the ON position. Refer to table 1.

OFF Up Open Open
ON Down Closed (Shorted) Closed (Shorted) This FMI 03 means that the ECM has determined that the contact is 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
Turn the key start switch to the OFF position and disconnect the negative battery cable.
Disconnect the machine harness connector(s) from the ECM.
Measure the resistance from Frame Ground of the machine to contact 12 and contact 7 (wire 200-BK(Black)). 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 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.
At the machine harness connector for the ECM, measure the resistance from contact J1-52 (wire F763-WH(White)) 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 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The harness is correct. Proceed to Test Step 3.
NOT OK - 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 F763-WH(White) and the circuit with the lowest resistance measurement. Repair or replace the machine harness.STOPTest Step 3. Check The Switch Circuits In The Harness
The machine harness remains disconnected from the ECM and the switch.
At the harness connector for the switch, connect a jumper wire between contact 12 (wire 203-BK(Black)) and contact 11 (wire F763-WH(White)).
At the harness connector for the ECM, measure the resistance from contact J1-81 and
