Schematic of the Creeper Control Rocker SwitchThis switch has two inputs to the ECM. One contact is normally open. The other contact is normally closed.An FMI 04 diagnostic code is recorded when the status of both the inputs are grounded.The possible causes of this diagnostic code are listed below:
The "NORMALLY CLOSED" signal circuit (wire F764-GN) is shorted to ground.
The "NORMALLY OPEN" signal circuit (wire F763-WH) is shorted to ground.
The Creeper Control Switch has failed.
The ECM has failed. This is unlikely.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 SWITCH
Turn the key start switch to the ON position.
The diagnostic code is active.
Remove the wire from contact 2 (wire 200-BK) at the switch.
Toggle the switch and note the status of the diagnostic code.Expected Result:The diagnostic code is no longer active in either position.Results:
OK - The diagnostic code is no longer active in either position.Repair: The Creeper Control Switch has failed. Replace the switch. Verify that the new switch corrects the diagnostic code.STOP
NOT OK - The diagnostic code is active in at least one of the positions. Proceed to Test Step 2.Test Step 2. CHECK THE SIGNAL CIRCUITS FOR A SHORT TO GROUND
Turn the key start switch to the OFF position.
Disconnect the machine harness connectors from the ECM.
At the harness connector for the ECM, measure the resistance between contact J1-64 (wire F764-GN) and frame ground.
Measure the resistance between contact J1-63 (wire F763-WH) and frame ground.Expected Result:The resistances should be greater than 5000 ohms.Results:
OK - The resistances are greater than 5000 ohms.Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. If the diagnostic code is still present, replace the ECM. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
NOT OK - The resistance is less than 5000 ohms on one of the readings.Repair: The circuit with the low resistance is shorted in the machine harness. Repair the machine harness or replace the machine harness.STOP
