ODBII Port does not work. I don't see a fuse labeled "ODBII". Any help with which fuse to check would be appreciated.

You are correct. There are no fuses labeled for this, but it is a shared fuse with other components.

So, I am attaching the wiring diagram and the fuse info that will help with this. Basically, it is in the junction block on the left side of the dash. Fuse 12 and 19 it appears are for the DLC. So, let's make sure these fuses are ok and we can go from there.
