What do you mean, "I changed the battery terminals......"
Was the battery hooked up with the correct polarity or not?
If you've accidentally gotten them backwards, even for a moment, there is most likely permanent damage to the PCM.

When the 120A goes, others burn with it. Check every fuse under the hood and interior with a test light or multimeter.
The ECM is protected, but only to an extent. Cross jumped the battery terminals didn't you?
