Corrosion and moisture Corrosion or damage due to moisture is one of the main reasons for ECM failure.

This happens over a period of time (5 to 10 years) due to the ECMs exposure to the elements.

How much is an ECU unit?

How does an ECU get damaged?

The ECU has seals around it which are supposed to prevent moisture from entering inside. Moisture is a bad thing to have in an ECU because corrosion will form on its components. If the corrosion is not cleaned away quickly, it will cause these components to get damaged. Then you will have a malfunctioning ECU.
