Hi there. It is possible that the ECU is damaged; however, it could be a simple problem like a damaged fuse, damaged electrical relay or problems with the dashboard itself. It’s best to have a professional mechanic to complete a check engine light inspection. This will allow the mechanic to attempt to access the ECU with the scanner. If it connects, then the issues are much easier to resolve. Replacing an ECU can only be done by a dealer; or authorized Mazda mechanic, which can get rather expensive.
