My adventures in diagnosing the BMW made me decide to get another bluetooth OBD plug for the Toyota, and use an Android tablet as an extended dashboard. But I can’t get it to pair. My phone can’t even see it. It can see the one in the BMW next to the car in the driveway, but it can’t see the one that’s two feet away in the 2013 RAV4. The light is on, so it has power, and I turned the ignition on to make sure that it was transmitting, but no dice.

Another weirdness of the car (which may or may not be related) is that one of the keys doesn’t unlock the car electronically, and I’ve never been able to get it to go into programming mode to reset the key, despite following all the incantations of opening and closing doors and turning the ignition on and off that they say to do online.

Looks like it’s not just me.

Mystery partially solved. I plugged in a stand-alone OBD reader, and there’s no output. Maybe I need to look for a blown fuse?

[Monday-afternoon update]

OK, I pulled the fuse, clearly marked “OBD,” and it’s good. Now what?

[Update]

I put the fuse back in, and now it works. Go figure.
