Pulling the trim panel can be slightly difficult the first time you do it but is really pretty easy once you figure out you have to pull up on the bumper cover and lift the front of the panel to get it out. No screws or bolts, just the 13 body rivets (if you have strong fingernails, you don't even need any tools).

With the VOM, you are looking for open/close transitions and not some particular value.
