2007 prius with code P0AA6

The P0AA6 code denotes a high voltage leak. Normally the high voltage system is isolated from the rest of the car. When such a leak is detected the car will run fine until it is shut off. Then it will not start again. Disconnecting your 12 volt battery cleared the code and allowed the car to run again.

The likely sources for the leak are the hybrid battery, transmission, and air conditioner compressor.

Steve at Phoenix Hybrid Batteries could get your car running again. I'm sure that Bull Head City is too far away for him to come to you, so you would have to go to Phoenix.

If the leak is in the battery, Steve can put in a brand new Toyota battery for $2000, including tax. With your low mileage, your car should go another few years without many issues.

 

$2000 to install a battery? It's a 45 minute job for an experienced pro...

 

This includes the new battery

 

Compared to last year it is great price. New Toyota batteries are down to $1625 this year. Even with tax, that's about $200/hour.

 

I doubt even a seasoned installer could install a Toyota New battery in 45 min. It is not just a simple swap like a Dorman.

$2000 is a decent price for a supply and install of a Toyota New.

 

You have to drive to the dealer for a new battery, prep the core return, install the electronics onto the new battery, then install in the car. That's already more than 2 hours, you still have to drive to the customer to install

The $2000 price is not a big profit maker, maybe $50 an hour. The benefit is recycling your bad modules back to the dealer whenever you buy a new one.

 

I think some one on this chat has a new improved hybrid battery different from the Toyotas? He's got cylindrical modules in them.

I think he's 2kcosta or something? Can't remember now

 

Last I heard he is selling his batteries for $1600. He may have to lower his price a couple hundred dollars to justify purchasing one of his batteries over a $1625 Toyota battery.

 

Wao! If there's a Toyota battery for such a cost, then I'd go for it.

Is the $1625 inclusive of tax,labour?

 

No, it just the price of the part. Taxes and labor are extra.

 

If you buy the part & install it there is a 1 year warranty. Dealer install gives a 3 year warranty. I understand that the @2ktToaster kit has a 2 year warranty.

 

The list price for a new Gen 2 battery is now $1950. Independent repair garages can get a wholesale discount in the $1625 range. It is difficult but not impossible to find a dealer that will sell for less than list price. Many Toyota dealers will not sell a battery to the public for any price.

 

A high-voltage leak (if it's in the battery) is the kind of problem that may be quite fixable (as opposed to, say, tuckered-out modules, which just have to be replaced).

OK, but don't you think that unskilled delivery should be charged at a minimum rate rather than a full mechanics rate, because many other things are being picked up in deliveries? Sounds like 2 hours is more than enough chargeable mechanics time to do the actual work.That's makes it about $125/hour.

 

you need tech stream software for the correct codes, and then tech info at toyota.com for the service manual. this is not for the faint of heart.

 

First, there is no doubt that your car has a high voltage leak. That is the one and only thing a P0AA6 code means.

One way to pinpoint the leak is with Toyota's Teachstream software. That system can give you sub or info codes that will show the source of the leak.

There is another way to locate a high voltage leak that takes just minutes and does not require any special tools. This test will not work if your car still takes 24 hours to detect the leak after it is cleared. Once the car gets to the point of immediately recording the P00A6 code after it has been cleared this test will be effective.

The video shows the test being run on a Gen 1 that uses a conventional key. To get a Gen 2 to "on" but not ready leave your foot off the brake and push the power button twice.

Until your car is properly repaired it is possible to keep driving it. You need to keep a code reader or tools to disconnect the 12 volt battery with you. Then you can clear the P0AA6 code whenever it comes back. This will allow the car to restart until the code comes back again.

Chap was referring to the possibility of replacing just the leaky battery module. Phoenix Hybrid Batteries has found leaky packs to be very difficult to rebuild. Once one module leaks the rest of them are much more likely to leak also. It's caused by the extreme Arizona heat.

Here is where the Gen 2 modules leak. It's not the same as the leaky terminals of the Gen 1 modules. The plastic battery module case cracks next to the mounting bolt. This module was under a slight over charge to give it just enough internal pressure for the bubble soap to work.
