    Hey folks,

    I am at about 1000 miles on a recent used engine/trans/inverter replacement and now I have triangle of death.

    car started with triangle on and vsc light. I drove car half a mile and parked it. Now all lights are on and it won’t start.

    I have the following codes

    P0AA6 - 526-614
    P0A08 - 264
    P3108 - 535

    everything I have found in search’s points to the inverter.

    I put a brand new toyota inverter coolant pump on when I switched the engine and that appears to be working ok, I feel it on and see movement in the coolant tank.

    many suggestions before I tear out inverter?
    Is there any wiring I can check?
    Many thanks
    Daley

    Sounds like you're already using techstream as an OBD2 scanner.

    Here is the workup for DTC P0AA6 (or P3009) : https://attachments.priuschat.com/attachment-files/2018/04/145252_2006_Prius_RM_-_P0AA6.pdf

    Here is the workup for DTC P0A08 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/21bpm/0a08264.pdf

    Here is the workup for DTC P3108 with INF 535 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/21bpm/3108535.pdf

    Try disconnecting the 12v at the battery for a couple of minutes, and see if the vehicle starts, and then fails to start a second time.

    Thanks for the info, much appreciated.

    Looks like I need a new inverter regardless going by the P0A08 code fix.

    I disconnected 12v for 10 min and car starts fine now with no lights.
    Waiting to see what tech stream shows.

    Tech stream came back with b1421 and b1271 which seem unrelated to inverter.
    I guess I’ll drive around some and see what happens.

    Will the vehicle restart a 2nd time?

    How many miles on the vehicle, and is the HV battery still OEM?

    Do you have issues powering the vehicle on / off, or does the dash / combination meter not illuminate all the time?

    Here is the workup for DTC B1271 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/21acw/cib1271.pdf

    Ignore DTC B1421 : https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/2044g/cib14212.pdf

    Not sure if the following link had updated workups or manuals (the above links are pretty dated). I've never used the following link, but it should contain *everything* you need : Service Manuals - Google Drive

    It would be great if someone could extract the manuals from Gdrive and back them up on http://mega.nz/ as well.

    I’ve driven it 15 miles, starts fine second and third time, mpg 43 no warning lights.

    car has 253k, original hybrid battery.
    Engine, trans and inverter have approx 80k on them.

    My inverter coolant level is slightly below low, I am on my way to get more coolant now. It got low due to a split hose, but I caught and repaired it before much coolant loss occurred.
