Failure Mode Identifiers (FMI) are used to communicate what the ECU has detected, not the root cause of the problem. For example 100-03 “Engine Oil Pressure: Voltage above normal”. The system detected that the signal voltage from this sensor input went above the valid voltage range. The root cause can be an open circuit, a short to a power source, a failed sensor, etc. In every case, refer to the troubleshooting guide for the specific product and the ways to determine the root cause.<\/td>\n<\/tr>\n

<\/td>\nFMI 00 “Data valid but above normal operational range”. If an
\ninput is still functioning in the valid range but the input is sending a
\nsignal that is above the acceptable limit of the parameter, an FMI 00
\ncode will be generated. On Cat Data Link events are normally used for
\nthis condition.FMI 01 “Data valid but below normal operational
\nrange”. An input that is still functioning in the valid range but
\nsending a signal below the acceptable limit of the parameter will cause
\nthe FMI 01 code. On Cat Data Link events are normally used for this
\ncondition.<\/p>\n

FMI 02 “Data erratic, intermittent, or incorrect”.
\nErratic or intermittent data includes all measurements that change at a
\nrate that is not considered possible in the real world condition and
\nmust be caused by improper operation of the measuring device or the
\nconnection to the module. Signal data from a component is present, at
\nleast intermittently. The signal is either unstable or invalid as
\nrecognized by the control doing diagnostics. Data can be correct
\nsometimes and not at other times. FMI 02 is also used for data that is
\ninvalid, such as an invalid state of a parity switch.<\/p>\n

Note: <\/b>This
\nis different from FMI 10. FMI 02 is used for situations where the rate
\nof change is not physically possible. FMI 10 is used for situations
\nwhere the rate of change is physically possible, but outside the
\npredefined limits of a properly functioning system.<\/p>\n

FMI 03 “Voltage
\nabove normal”. FMI 03 occurs when the voltage reading from the
\nidentified circuit is above the valid range. FMI 03 most often relates
\nto a signal circuit.<\/p>\n

FMI 04 “Voltage below normal”. FMI 04 occurs
\nwhen the voltage reading from the identified circuit is below the valid
\nrange. FMI 04 most often relates to a signal circuit.<\/p>\n

FMI
\n05 “Current below normal”. FMI 05 occurs when the current through the
\nidentified circuit is below the valid range. FMI 05 most often relates
\nto a driver circuit.<\/p>\n

FMI 06 “Current above normal”. FMI 06 occurs
\nwhen the current through the identified circuit is above the valid
\nrange. FMI 06 most often relates to a driver circuit.<\/p>\n

FMI
\n07 “Mechanical system not responding properly”. FMI 07 occurs when an
\nelectronic control sends an electrical command to a mechanical system
\nand the result is not within the acceptable range. An example of FMI 07
\noccurs when the ICM transmission (EPTC II) is shifting slowly as a
\nresult of a sluggish solenoid valve.<\/p>\n

FMI 08 “Abnormal frequency,
\npulse width, or period”. FMI 08 occurs when a frequency of the signal or
\nthe pulse width of the signal is not within the range that is expected.<\/p>\n

Note: <\/b>The period is the time in seconds for one cycle at a specific frequency.<\/p>\n

FMI
\n09 “Abnormal update rate”. FMI 09 pertains to the communication between
\nthe electronic controls on the data link. FMI 09 occurs when an
\nelectronic control is not able to receive any information from another
\nelectronic control, when the electronic control expects to receive
\ninformation.<\/p>\n

FMI 10 “Abnormal rate of change”. FMI 10 relates to a
\nsignal that changes too fast or too slow. The rate of change is outside
\nof the expected limit, but possible in the real world.<\/p>\n

FMI
\n11 “Failure mode not identifiable”. FMI 11 occurs when the electronic
\ncontrol identifies more than one FMI as being responsible for a single
\nproblem, or when the failure mode does not properly fit into any other
\nFMI.<\/p>\n

FMI 12 “Bad device or component”. FMI 12 occurs when a smart device (such as an ECU) has determined it has failed.<\/p>\n

Note: <\/b>In the past, FMI 12 had also been used to describe the following conditions:<\/p>\n
