Schematic for the Decelerator Enable SwitchThis diagnostic code is associated with the Decelerator Enable Switch. The switch is connected to two inputs of the ECM. One contact is open and the other contact is grounded during proper operation.This FMI 03 means that the ECM has determined that the normally open contact and the normally closed contact showing system voltage at the same time.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 1757 FMI 03 is active before performing this procedure.Test Step 1. CHECK THE SWITCH CIRCUITS FOR A SHORT TO THE +BATTERY CIRCUIT
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the machine harness connector(s) from the ECM.
Disconnect the connector for the switch from the machine harness.
At the machine harness connector for the ECM, measure the
