What is MID 118:
MID 118 refers to an issue with the Fuel Injector Control Circuit. This fault indicates that the ECM is not receiving the expected data from the Fuel Injector Control Module (FICM), which can lead to improper fuel injection timing, engine misfires, or reduced engine performance.
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 properly.
How to Fix It:
- Inspect the Fuel Injector Control Module (FICM) and its wiring for damage or malfunction.
- Test the FICM’s voltage to ensure it is within specifications.
- Check connectors for tightness and cleanliness.
- Replace the faulty FICM if necessary.
- Ensure that the ECM is receiving and correctly interpreting data from the FICM.
How to Avoid It Before It Happens:
- Regularly inspect the FICM and wiring.
- 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 to ensure smooth operation and prevent issues from affecting engine performance.
