Schematic of the transmission controlThis diagnostic code is associated with the transmission upshift switch. The transmission upshift 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 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 0622 FMI 03 is active before performing this procedure.

Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector(s) from the ECM.
Measure the resistance between frame ground (wire 202-BK) of the machine harness and contact 2 (wire 202-BK).Expected Result:The resistance
