I've Googled and scanned this newsgroup. Excuse me for asking this simple question, but how does one safely replace an ECU? Here us what I presume:
- Disconnect car battery
- Remove old ECU
- Install "new" ECU
- Reconnect car battery
- Start car
I am guessing that this is simple, like above, and that is why I can't find instructions on how o do it. I just wanted to check to make sure.
My son just bought a 1998 Civic in nice condition. The ECU will not produce any codes and the check engine light is always on. My searching on this indicates the ECU is probably bad. So, I want to try replacing it and I do not want to do it incorrectly and cause problems instead of solve them. Thanks, Don
