    If there's anything we've been trying to say over and over and over about P0AA6, it's that it's not battery out to see if there's a battery leak.

    It's scan tool out to see what the INF code is. If it's 612, then you look in the battery. If it's one of the others, then, well, you look there.

    If you haven't got a scan tool to see the INF code, you can look up and do what gen 1 Prius owners used to do when they got the equivalent code (it was P3009 in gen 1, and didn't give you the handy INF codes).

    Understood not necessarily battery out
    Alright so I need to check INF codes.
    That's not possible with Dr prius or torque app?

    If not I'll just pick up a scan tool that can do it. And recommendations

    About to pull the trigger on the autel Ap2500. That looks to be what will get me the inf codes.

    I have a spare old laptop that I can install techstream on but it seems sketch depending on where I get it from. I even saw it for sale on etsy.

    I saw advanced plug ins for toyota for the torque app but it says my version of android is too new. I have an old galaxy s9 I can use but I'm not sure if that's old enough?

    Thanks in advance for your input

    There are a few people here that have the AP2500, not familiar with it myself. There was recent mention of a glitch on Android causing problems (fixed with a not-yet-public update).

    From the adcopy, it seems like the AP200 has a couple more functions vs the AP2500. Either should scan all systems including INF codes.

    Torque is very limited, and the Toyota pack for it doesn't seem to add anything on a Prius.

    Ok so it's been a few weeks and I've noticed a few things

    I had a mobile mechanic give it the once over and had it up on a jack/ stands.

    Since then the code p0aa6 has appeared less often. There have been days that I have driven without the code showing up at all. I know it's anecdotal but can someone explain this?

    Also he had a Launch x431 scanner but couldn't pull any more codes than the p0aa6.

    I have another buddy who has another higher level scanner so hopefully I can get more codes.

    I haven't had much luck in figuring out what scanner would help. I looked through the list that was linked here and the one I was going to get was the ap200 but now they have the ap2500 which I don't know will do the same thing.

    Lastly and less of a priority is that the horn doesn't work. The fuse was pulled out when I checked so I put in a new fuse. As soon as I put the fuse in the horn just blares until I pull the fuse again. Can anyone tell me what the problem is?

    Thanks!

    The AP2500 will give you inf codes.

    It might not be able to do the bi-directional communication required for a few certain repairs- at least that is how I read the differences between the 2500 and the 200.

    Your horn problem is likely to be a shorted/damaged clockspring cable in the steering wheel assembly.
