Connections of the power management switch on the transmission control lever
This diagnostic code is associated with the power management switch on the transmission control lever. The switch is connected to two inputs of the ECM. The inputs are "Normally Open" and "Normally Closed". One of the inputs is open and the other input is grounded during proper operation.The FMI 02 means that the ECM has determined that the "Normally Open" and "Normally Closed" circuits are in the same state.Note: The following test procedure may create other diagnostic codes. Ignore these diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 1483 FMI 02 is active before performing this procedure.System Response:The power management control will be disabled.Test Step 1. CHECK THE OPERATION OF THE SWITCH
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector or the wires from the switch.
Connect one lead from the multimeter to the common contact 10 for the switch.
Connect the other lead from the multimeter to the normally open contact 11 for the switch.
Measure the resistance between contact 10 and contact 11. Note the resistance.
Disconnect the lead from contact 11 and connect the lead to the normally closed contact 12.
Measure the resistance between contact 10 and contact 12. Note the resistance. Expected Result:The resistance from contact 10 to contact 11 is greater than 5000 ohms, and the resistance from contact 10 to contact 12 is less than 5 ohms.Results:
YES - The resistance from contact 10 to contact 11 is greater than 5000 ohms, and the resistance from contact 10 to contact 12 is less than 5 ohms. Proceed to Test Step 2.
NO - The resistance measurements do not differ. The switch has failed.Repair: Replace the switch.STOPTest Step 2. CHECK THE OPERATION OF THE SWITCH
Connect one lead from the multimeter to the common contact 10for the switch.
Connect the other lead from the multimeter to the normally open contact 11 for the switch.
Actuate the switch and measure the resistance between contact 10 and contact 11. Note the resistance.
Disconnect the lead from contact 11 and connect the lead to the normally closed contact 12.
Actuate the switch and measure the resistance between contact 10 and contact 12. Note the resistance. Expected Result:The resistance from contact 10 to contact 11 is less than 5 ohms, and the resistance from contact 10 to contact 12 is greater than 5000 ohms.Results:
YES - The resistance from contact 10 to contact 11 is less than 5 ohms, and the resistance from contact 10 to contact 12 is greater than 5000 ohms. Proceed to Test Step 3.
NO - The resistance measurements do not differ. The switch has failed.Repair: Replace the switch.STOPTest Step 3. CHECK THE GROUND CIRCUIT OF THE SWITCH IN THE WIRE HARNESS.
Connect one lead from the multimeter to contact 10 of the wire harness connector for the switch.
Connect the other lead from the multimeter to frame ground.
Measure the resistance between contact 10 and
