When do you need to replace an ECM unit?
Vehicle owners eventually need to replace a failing ECM. Initially, the unit might still work, but over time a degradation in the performance of the vehicle may take place, including poor fuel mileage and efficiency, problems shifting with automatic transmissions, and jerking or stopping while driving.
Can a new starter cause an ECM to fail?
Installing a new starter can also cause ECM failure. This is because they often bypass the surge protector on the ECM, leading to a power surge when you start the vehicle. The same thing can happen if you get your wires crossed while jumping your car. A failing battery can also cause ECM failure.

When to reprogram an engine control module ( ECM )?
