    Wife and I got got the red triangle while on vacation near Williamsburg VA. limped into Casey Toyota and were told that we needed a new HV and computer assembly for $4500 (codes: P0A80, P3020, P3000). The car has just over 200k miles and I don't think it's worth the cost. We decided to rent a car to get home and think things through. Based on the posts here I'm going to call Toyota tomorrow to see if I can get a goodwill discount. Long shot considering the miles but who know. More probable options below. Any thoughts or suggestions?

    1. tow it it to Macs in Ashland
    2. tow it up to northern va and take it to Hybrid Shop in Gainesville (Any other repair shop suggestions?)
    3. Tow it home and install new battery from 2k1Toaster (sent an email earlier asking about availability)
    4. mobile install using Greentec (claim "brand new" cells and 48 mo warranty)

    Thanks!

    Did they give you a print out of the codes?
    Did you have the car die on you while it was running?

    You could also try and pull the 12 volt battery and see if the code returns until you get it back up to the DC area.

    Mac’s is a well known shop and can get you sorted.

    Good luck and keep us posted (y).

    $4500 for a battery? Toyota should be ashamed. Kick you when you're down.

    They are hoping to buy your car for $500 and sell you a new car

    @Raytheeagle - yes. I disconnected the battery but the warning lights came back about 10 minutes later. Casey gave me a printout of the codes: P0A80, P3020, P3000. I'll update my original post with this info. Another option I came across is Greentec. I've reads some complaints about them but they have a listing for a battery pack with "brand new cells" and 48 mo warranty.

    The P3020 points to block 10 becoming weak, so that’s the opportunity ;).

    Greentec doesn’t have the best track record from the posters who have used them here. Before you dive in to Greentec, ask them how you know the modules are new:
    • are they willing to show you the serial numbers?
    • Do you know how to read the serial numbers?
    • Where are they getting the “new” cells?
    • Given you’ll buy about 2 hours from where you are from, how does a replacement under warranty work?
    Some things to think about and sleep on before you make a decision ;).

    Good luck and keep us posted (y).

    @Raytheeagle do you think the codes suggest that cleaning the fan may help? I'd have to drive 2 hours to get down there to do it.

    It could be as simple as cleaning the hv fan, but the P3020 suggests block 10 has issues, which is why the P0A80 is displayed.

    I’d have it towed to Mac’s and see what those folks have to say.

    If you have AAA, Ashland is within towable distance, so it shouldn’t cost anything.

    Good luck and keep us posted (y).

    Giving Toyota a try this morning. Before I call Mac: is there anything I should be asking them about the services they offer? Also I got an email back from Greentec saying "The cells we used are brand new, the only thing we reused is the casing." I'll ask about where they are getting their cells and for serial numbers. I don't know how to read them though, any resource you can point me to?

    I’d just lay your situation out on the table and see what they say. They’re good folks.

    As for the greentec folks, I’d be from Missouri: Show Me;).

    To read the serial numbers, each module has identification that can be interpreted. Search around here as there are plenty of links to pictures and members deciphering them:). Ask them for pictures of the modules serial numbers and post them up here. If they are getting new modules that have NEVER been used, I for one would like to know more;).

    Good luck and keep us posted (y).

    Got a little help from Toyota- price to replace Battery ECU and HV is $3,600. Still not sure it's worth it so will reach out to Mac now. What are the odds that the ECU and HV failed at the same time?

    From the past posts, greentech uses words that"imply" new modules but their meaning of "new" is (at least 1 module out of 28) is from the new generation of prius.

    If you go with this option, you can have them open the battery case before install so you can see if the modules/bus bars are new. There should not be any discoloration in any of the new modules. It takes less than a minute to open up the case. If they refuse, then you'll know something is wrong.

    There is also no reason for them to reuse anything if it's a new battery from Toyota, they buy it new, they should sell it new. A used case would only imply it's not new. Toyota does not sell modules, you can't buy them without a new case

    Look at the first four digits of the serial number on the module. It gives the manufacture date of the module. The first 2 digits are the day of the month. The third digit is the month (1-9, x,y,z) and the fourth digit is the year. L would be 2010
    S would be 2017
    T would be 2018

    We do not have a lot of Prii options in NoVA.
    I would call a few dealers to get a cost quote (Miller in Manassas, maybe Koons, Jack Taylor in Alexandria).
    Seems to me some have been getting quotes better than $3600 in recent 12-months. I thought Toyota reduced the batt price.

    I recently found my repair shop West Springfield Auto has a repair tech orig from Toyota, So I used him for inverter water pump replacement, after I got the parts. Outside chance your HV cooling fan is blocked as the cause of the issue.

    There is a place in Annapolis travels out to Fx called PriusHybridRepair.com but I do not have any feedback.

    Mac's in Ashland was somewhat popular as a Re-Involt installer, before Dorman bought out Re-Involt.

    Extremely unlikely the HV ECU needs to be replaced.

    Ask how much the computer costs.
    Then have them remove that cost from the estimate.

    Make sure they are cleaning the HV fan as part of the service.

    They are adamant about wanting to install a new battery ecu but will install th HV for $2641 if I sign away liability or something. I called Mac and they say it could be much less but worst case would be $2700- 3400 to replace everything plus $260 to have the car towed over there. I'm leaning to just having Toyota do all the work to so I can move on to other things. Only thing that's killing me is dropping $3600 on a car with 200,000 miles. Reality check?

    This dealer sounds very shady. I wouldn't trust them to do an oil change.

    The ECU is rarely replaced. However the dealer needs to swap it over from the old pack for the Toyota installed pack. Sounds like they're wanting to buy the assembly with the HV ECU preinstalled which is significantly more expensive and less labour. I would question why. Are they lazy and trying to fleece you for money? Or are they incompetent and don't know how to install a HV battery? Either way, I would tow that car out of there asap.

    I very much doubt the ecu needs to be replaced.
    The only ones I see replaced are ones with green crusty corrosion or black burnt areas.

    (I wish some dealer would try this ruse on me. I'd call their bluff.First I'd approve the $2641, and say I'd definitely consider replacing the ecu if they can present me with evidence that it needs replacing. As in take out the part and let me look at it. When they show it to me, if there isn't green corrosion or black/burnt areas, I'd decline.)

    For you, Id say or take them up on the $2641 price. That is a good deal no matter what they make you sign.

    Sounds like they want you to sign a big huge made-up statement saying something like "Customer refused ECU repair and may die or become physically disfigured and will most definitely turn into a Vampire because of high volatge and [insert more scary language here]."

    Whatever. Lol.

    If they intimidate you into also getting the ecu, then make sure they give you the old one back. It is yours. You are 100% entitled to it. Do not bend.
    At the very least you can sell it on ebay

    Call.me if you want some moral support or want any additional info.

    Eric, I don't want to give you a call if it's too late but I really appreciate the offer. I'll put my number in status if you have time to chat.

    My big question is whether any damage can occur by not replacing the hybrid battery ecu at the same time they install the HV battery. I read that most battery ecu issues seem to involve corrosion so it should be obvious that I would need one once they take it out. Is there anything wrong with asking that they install the HV battery first to see if it solves the problem? And then install the hybrid battery ECU if that doesn't work? I'm worried that they'll say that they won't install the hybrid battery ECU and I'll be stuck at the dealer. I'm willing to install the hybrid battery ECU myself. Some posts say that it should be plug and play but then I read others that suggest I may have to contend with things like the immobilizer. Are there others? If they refuse to install the hybrid battery ECU I'm thinking of just asking that they not put the seats back etc so that I could do it. Do you see any issues with this?

    Regarding the Hybrid Battery ECU. I noticed when we were limping to the dealer that the HV fan was running very loudly. I read a post here that said that the ECU also controls the Battery Fan Relay. Could the fan running loudly suggest a bad ECU? Also, I did not get the subcodes from the dealer but I found these on PC. I plan on asking them tomorrow. 123 and 124 seem to be connected with a bad hybrid battery ECU. Is that right?

    P3000 - HV Battery Malfunction
    123

    Input of abnormal signal from battery ECU (HV Battery System Malfunction)

    124
    Input of abnormal signal from battery ECU (high voltage fuse blown out)

    388
    Discharge Inhibition Control Malfunction. When charged battery is low due to
    leaving the vehicle in N position, gas shortage or HV system malfunction

    389
    Drop of high voltage. When main battery is dead or main battery is dead due to HV system malfunction

    There are two ECUs with similar names.

    • Hybrid Control
    • Hybrid Battery
    They are different, and installed in different locations. Do not confuse them and the terms are not interchangeable.

    Thanks. Didn't mean to be careless. I'll go back and edit to be clear I'm talking about the hybrid battery ECU
