14+ 2009 Honda Accord Fuse Box. There should be continuity between terminals b1 and c4. I can’t figure out how to remove the combined fuse box in the secondary under hood box of my 2011 odyssey.

In your accord, the power comes from fuse #15 in the underhood fuse box. These are the only two fuses for the radio. In most cases when i have a non responsive obd connector it is a blown fuse.
