What causes an ECU to fail?
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.
What happens if the ECU fails?
If the ECU fails completely, it will leave the vehicle without engine management control, and will not start or run as a result. The engine may still crank, but it will not be able to start without the vital inputs from the computer.
