What is CID 247 & How to Solve It?

What is CID 247:

CID 247 refers to an issue with the fuel system, specifically the fuel injector control module (FICM). The ECM detects that the injectors are not receiving the correct signals, which could result in improper fuel delivery and engine performance issues.

‍

Why This Happens:

• Faulty Fuel Injector Control Module (FICM).
  
• Shorted or damaged wiring in the injector control circuit.
  
• Loose or corroded connectors.
  
• Power supply issues affecting the FICM.
  
• ECM failure to interpret injector control data.
  
  

How to Fix It:

1. Inspect the Fuel Injector Control Module (FICM) and wiring for damage.
   
2. Test the FICM to ensure it is sending proper signals to the fuel injectors.
   
3. Check connectors for cleanliness and tightness.
   
4. Replace the faulty FICM if necessary.
   
5. Ensure stable power supply to the FICM and ECM communication.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the FICM and wiring for damage.
  
• Keep connectors clean and free from corrosion.
  
• Perform routine diagnostic checks to monitor injector control performance.
  
• Ensure stable power supply to the FICM and ECM communication.
  
• Clue’s fuel management services track injector control systems and prevent issues before they affect engine operation.
