What is FMI 10 & How to Solve It?

What is FMI 10:

FMI 10 refers to power supply or ground fault. The ECM detects that there is an issue with the power supply or ground connection to a specific sensor or component. This can result in no signal or an invalid signal being sent to the ECM.

‍

Why This Happens:

• Power supply issues or interruption.
  
• Faulty ground connections.
  
• Damaged or shorted wiring in the circuit.
  
• Loose or corroded connectors.
  
• Failed control module or sensor.
  
  

How to Fix It:

1. Inspect the wiring for visible damage or short circuits.
   
2. Check the power supply to the sensor or component.
   
3. Ensure proper grounding for the circuit.
   
4. Replace any damaged connectors or wiring.
   
5. Test the sensor or component for proper functionality.
   
   

How to Avoid It Before It Happens:

• Perform routine power and ground checks.
  
• Regularly inspect wiring and connectors for wear and corrosion.
  
• Ensure a stable power supply to all critical components.
  
• Clue’s equipment maintenance services monitor power supply and ground connections to prevent signal failures.
