Default 12V battery change reset?

Do I need to do anything when replacing the 12V battery other than swapping old with new and reconnecting battery terminals? No ECU relearn or anything?

Default Re: 12V battery change reset?

disconnecting the 12V resets all computers.

I'm not sure if it's necessary, but some models require an idle re-learn procedure:

It may not be required for the HCH.


I've never done it on any of my Hondas.
