    I would check the 12 volt via the method at http://priuschat.com/forums/newbie-forum/73400-weird-stuff-happening-mpgs-dropping-test-battery.html after the car's sat overnight. If you're still on the original 12 volt, I'd replace it. It's most likely bad given the age and mileage. (I replaced my 12 volt on my 06 in Feb 2011 on my Prius that was bought January 06. It was getting marginal.)

    I checked my 06's warranty booklet and on page 6 (one spot where it shows warranty lengths, including CA emissions), it mentions a bunch of states but WA isn't one of them.

    Thanks for checking your warranty booklet and I think it looks like in 2009 Washington was added to the CARB list.
    I tested the 12v battery using the MFD method and engine off headlights on it never dropped below 12.1 volts. I have been watching the 12v even before this issue with the HV battery can up just because a 2006 battery could be getting close to it's end but it has been testing fine.

    The Red Dwarf lives again! After the dealer handed me a a $5000.00 estimate to repair this car I decided to try and repair it. I would have purchased a wreaked one and stripped it before 5k to a dealership to troubleshoot by replacing everything but the floor mats. So with this GREAT forum and some very knowledgeable people here away I went.

    I have a good mechanical background on electrical systems on heavy equipment ( mining and construction) and after reading info here I thought I would attack this myself.
    P3019 pointed to VBB9 and from what I read here I more then likely had a bad module in that block. The P3000 code had a TSB that said ECU replacement.
    Seilerts steered me to jdenenberg who had some good tested modules. Thanks to both of you guys BTW. Anyway I bought 6 modules. We have 2 Prius's in our family 2004 and my 2006 was I figured stock up.
    I removed the HV battery following the service manual to the letter. Opened up the HV battery and checked voltages after removing the bus bars.

    All were at 8.19 to 8.20 v Except for one in VBB9 which was 6.85v ( the bad one) VBB14 was 8.15v which was probably OK but hey I had plenty Then I used the Supermate DC-6 to discharge my overcharged modules. Which overcharged because of the bad one more than likely. Brought them all within .020mV of each other using my Fluke 88 and the DC-6 in discharge mode at .6 mA.
    The one thing that I did notice was that 5 of the sense wire terminal ends had some green corrosion growing on the wires. vincent1449p replied to my request for a part number for the sense wires and I asked for price and ETA if i ordered the harness and he hasn't gotten back to me yet. So I soldered the terminals to the wire on the bad ones(I will order this harness because I have my doubts about the corrosion) and assembled everything and reinstalled the HV battery. Test drove and all is well. No codes and the MFD is very stable now. It was all over the range before which was probably due to the corrosion on the sense wire terminals. Thanks to all on the forum that helped answer my questions. Time will tell if this module replacement will work but it wasn't that bad to do. Just be very attentive of the modules after you remove the HV battery cover and while you are removing the bus bars.
    I bought the Autoenginuity software and installed it on my laptop and after I repaired my problem I got the software working ( they sent me the wrong code). This program looks very good from what I seen so far. The toyota enhanced version covers a lot of the items you need to see to troubleshoot a hybrid system .
    So if you live around the Olympia, WA area and get the triangle of death message me I can see if I can help you out. Thanks again to everyone who helped me out.

    Hello,
    Your post caught my eye because I am in the Olympia area and although my car is not running any different, I have a red triangle and engine light on. My mechanic looked at the codes and said it is the hybrid battery and he does not fix those. So now I am left with who to take it to, other than dealership. I question that the whole hybrid battery needs replacing and perhaps like yours, only some cells or connections. Any suggestions?
    THANK YOU!!

    welcome! cell replacement is a big job. equipment needed and a lot of time and knowledge. if you don't want to pay for a new battery, i suggest checking with auto parts suppliers for a dorman rebuilt battery. all the best!(y)

    Karen here is the warranty information The 2014 list of CARB States in the US | PriusChat

    Washington did not become a CARB state until 2009 and does not enjoy the 150,000 mile/10 year provision.

    As this thread died 5 years ago, it is possible that none of the participants are still active on PriusChat.
