Red triangle but good mpg

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).

 

tech stream is the gold standard

 

See post #6 for scan tool recommendations.

 

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.

There is a Prius specific set of PIDs that may be loaded. Search these forums for more details, but here is one thread:

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.

 

When the Autel is showing the P0AA6, can you get it to show you the freeze frame for the P0AA6? The INF code is in there.

Don't clear the P0AA6 the first time it comes up. There will only be a 526 INF code then, which doesn't tell you anything. The more-specific 611, 612, 613, or 614 will only come up on the next start while the 526 is present.

I believe there are three different scans that you can do. Did you do a full scan?

Edit: You do not want to use the service tab----> ev battery. You need to do a full scan of the car. Also, see post # 33.

 

I've only ever used the 'full scan' function.

 

@Dahvid
Now that the Autel AP2500 doggle and app are working for you, you need to look at the freeze frame data for the P0AA6 code. Also, see posts # 33 & # 21.

After running a "full scan", are there any other trouble codes, or do you only have the P0AA6 code?

 

Since you own an Autel AP2500, can you please describe to Dahvid how to find the freeze frame data for the P0AA6 code?

 

I wish I could, but I only spent a few hours using it, that was months ago, and I'm 200 miles away from the car this weekend.

What I do remember is that when I did the 'full scan' option the UI clearly indicated that it was stepping through different software modules to interrogate different ECUs in the car. Afterward it presented a list of all findings.

Freeze frame data was not a real factor in the diagnosis I was working, so I never looked for it.

I might get a few minutes to noodle with it and do screenshots next week, no promises.
