What is MID 41:

MID 41 refers to an issue with the Fuel Injector Control Module (FICM). The ECM detects a fault with the injector control circuit, which can cause improper fuel injection, misfires, or engine stalling.

Why This Happens:

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

How to Fix It:

  1. Inspect the Fuel Injector Control Module (FICM) and wiring for visible damage.
  2. Test the FICM to ensure it is sending proper signals to the fuel injectors.
  3. Check connectors for tightness and cleanliness.
  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 FICM 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.
