What is MID 148:

MID 148 refers to an issue with the Fuel Injector Control Circuit. The ECM detects that there is an abnormal signal or communication failure in the fuel injector control system, which can result in improper fuel injector timing and 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 process data from the FICM correctly.

How to Fix It:

  1. Inspect the FICM and wiring for visible damage or malfunction.
  2. Test the FICM’s voltage to ensure it is functioning correctly.
  3. Check the 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 wear or 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 fuel injector control systems and prevent issues before they affect engine performance.
