OBD-II Port not working

My OBD-11 PORT is out and I was wondering which fuse to check.
Similarly, your YouTube video on the Honda mine not only has an issue with the OBD-II, but with power locks, radio and power tailgate as well.

I believe I likely blew the fuse incorrectly using a memory saver when changing my battery.

Thanks so much for your help!

Hello,

Check the number 20 fuse located in the fuse box under the dash. That should be for the OBD port power. It is a 10A fuse.

See diagram below for reference.

Let me know of any questions.
Thank you.

Thank you! Everything is back in working order. It wasn't fuse 20, but another 10-amp fuse close by.
