What is FMI 7 & How to Solve It?

What is FMI 7:

FMI 7 refers to low voltage detected in actuator circuit. The ECM detects a low voltage reading in the actuator circuit, which can cause the actuator to malfunction and lead to poor system performance.

‍

Why This Happens:

• Faulty actuator or malfunctioning circuit.
  
• Damaged wiring or corroded connectors.
  
• Insufficient voltage supply to the actuator.
  
• Short or open circuit in the actuator system.
  
  

How to Fix It:

1. Inspect the actuator and wiring for visible damage or malfunction.
   
2. Test the actuator to ensure it’s receiving the proper voltage.
   
3. Check the wiring and connectors for visible damage or corrosion.
   
4. Replace the faulty actuator or wiring if necessary.
   
5. Ensure stable voltage supply to the actuator and ECM communication.
   
   

How to Avoid It Before It Happens:

• Regularly inspect actuators and wiring for wear or damage.
  
• Perform routine voltage checks to ensure stable power supply.
  
• Keep connectors clean and corrosion-free.
  
• Clue’s equipment maintenance services monitor actuator systems and help prevent voltage-related issues before they affect performance.
