5 The signalis shorted to the another voltage source. The sensor needs to be calibrated. An ECM has is unlikely. FMI 01 "Data Valid But Below Normal Operating Range"-Everyelectronic controlsystem sets alow limit for the expected operatingrange ofthe limit includes signals that are under thelower low signalcould be the oilpressure sensor is stillworkingbut sendingasignalbelow the expected limit willcause aFMI01to be ofthe conditions that can cause the FMI01diagnostic code to be activated are:The medium or component that is beingmonitored is below the normalrange. Poor connections in the circuit. The sensor has failed. An ECM has is unlikely. FMI 02 "Data erratic,intermittent or incorrect"-The signalfrom acomponent is reads the Diagnostic information can not read the signalappears to begone,unstable or datacan be correct or incorrect ,this conditionrelates to communication between is an example ofcommunication between hen the monitoringsystem is lookingfor the engine speed from the Engine ECM over the ofthe conditions that can cause the FMI02diagnostic code to be activated are:There is apoor connection in the circuit.

6 The signalis intermittent or erratic. The software has been changed. The signalis receivinginterference from another circuit. The signalis out ofthe range. An ECM has is unlikely. Page8of11 FMI 03 "Voltage AboveNormal"-The component or system voltage is higher than the often relates to ofthe conditions that could cause aFMI03diagnostic code to be activated are listed ofpower supply. A open circuit or abad connection. A short to another voltage source. The sensor or the switchhas failed. An ECM has is unlikely. FMI 04 "Voltage Below Normal"-The component or system voltage is lower than the code most often relates to apower that could cause aFMI04diagnostic code are listed circuit is shorted to aground source. The circuit is open or has apoor connection. The ground circuit has failed. A component has failed. An ECM has is unlikely. FMI 05 "Current Below Normal"-The current throughthe component or the system is lower thanthe most often related to adriver that could cause aFMI05diagnostic code are listed is an open circuit or apoor harness connection.

7 The component has failed or has an open internally. An ECM has is unlikely. FMI 06 "Current Above Normal"-The current throughthe component circuit is higher than is most often related to adriver circuit for Diagnostic code is similar toan FMI04diagnostic that could cause aFMI06 Diagnostic code are listed component has failed. There is ashort circuit to aground source in the machine harness. An ECM has is unlikely. Page9of11 FMI 07 "Mechanical SystemNot Responding Properly"-The controldetects asignalthat is sentto amechanicalsystem and the response is not that could cause aFMI07 Diagnostic code are listed component responds improperly. The component is mechanicallystuckin aposition. The mechanicalcomponent has failed. The engine is shut down. The machine is beingused improperly. FMI 08 "Abnormal Frequency,Pulse Width or Period"-This occurs when the signalis not in theexpected also relate to that could cause aFMI08diagnostic code are listed harness connections are intermittent or poor.

8 The signalis noisydue to nearbyinterference. There are loose mechanicaldevices. Incorrect component installed. The component has failed. An ECM has is unlikely. FMI 09 "Abnormal Update"-This relates to communications on the whenacontrolis not able to get information from another that could cause aFMI09diagnostic code are listed controlmodule is not communicatingon the datalinkcorrectly. The rate ofdatatransmission is abnormal. The datalinkcircuit has failed. There is amismatchofsoftware. An ECM has is unlikely. FMI 10 "Abnormal Rate of Change"-This relates to asignalthat changes too fast or too ofchange is outside ofthe expected that could cause aFMI10diagnostic code are listed component has failed Page10of11 Poorconnections in the circuit. The medium or component that is being monitored has failed. An ECM has failed. This is unlikely. FMI 11 "Failure Mode Not Identifiable"- The control identifies more than one FMI as beingresponsible for a single that could cause a FMI 11 Diagnostic code are listed is a mechanical failure.

9 There is damage to multiple circuits. An ECM has failed. This is unlikely. FMI 12 "Bad Device or Component"- The electronic control sends a signal and the electroniccontrol expects a response. The control receives no response or the response is that could cause a FMI 12 Diagnostic code are listed component has failed. There is a failure on the data link. There are one or more controls with mismatched software. An ECM has failed. This is unlikely. FMI 13 "Out of Calibration"- The electrical signal is not within limits for a specific that could cause a FMI 13 Diagnostic code are listed is required. The component has failed. The data is out ofthe range. An ECM has failed. This is unlikely. FMI 14 "Parameter Failures"- This Diagnostic code is set up for special circumstances for aparticular component. The FMI 14troubleshooting procedure for the component will list the possibleconditions that can cause this
