What is Failure Mode Indication?
FMI is a standardized approach to identifying what tyope of failure has occurred in a component of a system. It is
often described as a more detailed version of a check engine light , not just
telling you there is a problem, it also tells you where to look for it. FMI generates codes that explain where the
problem lies and what kind of problem it is, saving maintenance time by letting your troubleshooting focus on the
specific areas affected.
How does Failure Mode Indication Work?
Failure Mode Indication uses the J1929 standard from the
heavy vehicle industry, and it works by monitoring system
components closely in real time. If it detects an fault, the Failure Mode Indication system generates a fault code ,
which identifies the specific problem and the component that it is found in.
In the AutoPi Cloud you can see your vehicle failures in real time.
The result is more targeted troubleshooting, so failures can be resolved more efficiently, saving time and money.
Compliant with J1939, FMI will monitor your engine parameters, emissions systems , ignition and other crucial
components, so you always know exactly where the problem lies.
Key Components of Failure Mod indication
Diagnostics Trouble Codes (DTCs) — The system generates DTC codes that includes an
FMI code as part of that data. To identify the location and cause of a fault, DTCs are essential.
Sensors and Actuators — Located around the vehicle, this hardware provides essential data in
the operation of various systems.
Controller Area Network (CAN)
The Importance of Failure Mode Indication in Troubleshooting
While the obvious benefit of FMI is that it gives you the exact nature of the fault, the standardized set of codes
provides more information. With the data provided, you can quickly understand the cause of the issue without needing
extensive real-time monitoring or observation, making it much faster to make the repair.
Examples of FMI Usage
Automotive — With modern vehicles so reliant on multiple complex systems and technology,
Failure Mode Indication is essential for fast, accurate identification of problems.
Industrial Automation — For modern manufacturing, much of the work is carried out robotic
machinery and automated conveyors. These complex systems often contain thousands of processes, where Failure
Mode Indication allows for fast, effective fault discovery.
Healthcare — Failures in medical devices can be catastrophic for patients, so having Failure
Mode Indication solutions helps quickly find and remedy issues in complex machinery.
Conclusion
Failure Mode Indication provides you with robust, highly effective approach to identifying faults within complex
machinery. From automotive applications to healthcare, as equipment become smore complex, the need for targeted
diagnostics is increasingly important. Understanding FMI gives you an edge when dealing with preventative
maintenance and reactive troubleshooting.
