Strange electrical issue when using bluetooth OBD-II thingy
Here's a strange one you guys might be able to help me with. I have one of those bluetooth OBD-II readers that you plug into the port under the dash and get real-time readouts of engine parameters, read and clear codes, etc. I believe it's the OBDLink MX, but I can check if it helps.
Anyway, when it's plugged in and I lock the doors with the key fob, 90% of the time the horn does't beep when the locks close. With it unplugged, it beeps when I lock it consistently. Not that I really care, but it's got me scratching my head. Everything else works just like it normally does, including the door locks themselves.
Any idea what might be happening?
