What does FMI mean for fault codes?
Failure Mode Identifier
Failure Mode Identifier (FMI) Codes on J1939 data link. The FMI is used along with the SPN to provide specific information that relates to a diagnostic trouble code (DTC). The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected.
What does SPN and FMI stand for?
Suspect Parameter Number (SPN) Represents the SPN with error. Every defined SPN can be used in a DTC. Failure Mode Identifier (FMI) Represents the nature and type of error that occurred, e.g., value range violation (high or low), sensor short-circuits, incorrect update rate, calibration error.
What is the meaning of the terms mid PID SID and FMI?
Now that we have defined MID (The component) and PID (types of data), we can talk about Failure Mode Identifiers (FMI). 2 = Data Erratic, Intermittent or Incorrect (rationality) 3 = Voltage Above Normal, or Shorted to High Source. 4 = Voltage Below Normal, or Shorted to High Source.
What is SPN code?
The Suspect Parameter Number (SPN) is diagnostic fault code terminology found on some Caterpillar ® products using a J1939 CAN data link. Only the SPN numbers that are intended to be used on Caterpillar ® products are listed.
What does FMI 7 mean?
7. Not Responding Properly. 8. Abnormal Frequency, Pulse Width, or Period.
What does Sid PID stand for?
Severe and Profound Intellectual Disabilities (SID/PID): A generic classification of disorders which involves physical, sensory, intellectual, social-interpersonal performance deficits significantly below average.

What are the possible FMI values for a DTC?
Every diagnostic trouble code (DTC) that you find will have a FMI. This code is set by the ECM detecting a variety of problems, such as too much voltage, not enough voltage, resistance is in correct, and so on. So here is the list of possible FMI values: 0 = Data Valid but Above Normal Operational Range, Most Severe Level
Which is the least severe level of FMI?
8 = Abnormal Frequency or Pulse Width or Period 15 = Data Valid but Above Normal Range : Least Severe Level 16 = Data Valid but Above Normal Range: Moderately Severe Level 17 = Data Valid but Below Normal Range: Least Severe Level 18 = Data Valid but Below Normal Range: Moderately Severe Level 19 = Received Network Data in Error: (Multiplexed Data)
