Schematic for the Fuel Level sensor
This diagnostic code is associated with the Fuel Level sensor. An FMI 05 diagnostic code means the machine ECM has determined the sensor circuit current is below normal. Possible causes for this diagnostic code are:
The sensor has failed.
There is an open wire in the circuit.
The attachment code is incorrect.
The machine ECM has failed, but is unlikely. Note: Poor connections are often the cause of a problem in electrical circuits. Before performing this procedure, inspect all the machine harnesses and connectors involved in the circuit. Make sure to verify that all of the connections in the circuit are clean, secure, and in good condition. Correct any problems found with any of the connections. Verify the diagnostic code CID 0096 FMI 05 is still active, before continuing with this procedure.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes now, but clear those diagnostic codes when the original diagnostic code has been corrected. Test Step 1. CHECK THE SENSOR.
Turn the disconnect switch and the key start switch to the OFF position.
Disconnect the machine harness connector from the Fuel Level sensor.
At the Fuel Level sensor machine harness connector, place a jumper wire between the contact for wire 495-GN(Green) to the contact for wire 235-BK(Black) in the sensor harness connector.
Turn the disconnect switch and the key start switch to the ON position.
Observe the status of the CID 0096 FMI 05 diagnostic code. Expected Result:The CID 0096 FMI 05 diagnostic code remains active. Results:
YES - The diagnostic code remains active. The sensor is not the problem. Go to Test Step 2.
NO - The diagnostic is no longer active. The sensor has failed.Repair: Replace the sensor. Go to Test Step 3.Test Step 2. CHECK THE HARNESS FOR AN OPEN.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connecting the Fuel Level sensor to the Monitor module.
The jumper wire in the harness connector remains in place.
At the harness connector for the Monitor, measure the resistance from signal contact 1 (wire 495-GN(Green)) to 1 (wire 235-BK(Black)) in the Monitor harness connector. Expected Result:The resistance is less than 5.0 ohms.Results:
YES - The resistance is less than 5.0 ohms. The harness is correct. Go to Test Step 3.
NO - A resistance is more than 5.0 ohms. There is an open circuit in the machine harness.Repair: The open is in wire 495-GN(Green) or in wire 235-BK(Black) of the machine harness. Repair or replace the machine harness.Go to Test Step 3.Test Step 3. CHECK THE DIAGNOSTIC CODE STATUS.
Reconnect all harness connectors. Make sure that the connectors are fully seated. Observe that the clips on each connector are securely fastened.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Check the status of the CID 0096 FMI 05 diagnostic code. Expected Result:The CID CID 0096 FMI 05 diagnostic code is not active.Results:
YES - The CID 0096 FMI 05 diagnostic code is not active and does
