Will AAA work in any state, such as if I live in Montana but I break down in Idaho?

My car’s been acting a little funky lately, and my neighbor loaned me their OBD reader. But here’s the thing—I don’t know where to plug this thing into. Where is the OBD port on a 2016 Honda CR-V?

I’ve had the same 2006 Honda Odyssey in my family for years, and it’s never given us any issues. But today, I was trying to start her up after being away, and the side door won’t open. What should I do if my van’s sliding door won’t open?

I just bought an old Ranger to work on in my garage, and I’m trying to get a read on its trouble codes. One problem—I can’t find the port. Where is the OBD port located on a 1993 Ranger?
