    Good day
    Sorry I'm using google translator.
    I need help, my Toy prius3 2010, the cylinder head gasket and timing chain were changed. Unfortunately the car was in the service for a long time, first the 12v battery died and then the HV battery. / Both were charged, but the car now runs ICE, but won't start. Is it possible that some unit somewhere forgot some settings?
    The only thing I noticed is that the service used bosh spark plugs instead of the original denso ones.
    I'm currently in the process of recharging the HV battery.
    Thank you.

    Spark plugs can be bosh, the heat value and brand and construction may affect fuel consumption, but they should all be able to light the engine. You can run a spark plug test to make sure they are working, are there any fault codes, if possible you should check the data stream to find the cause, perhaps just a sensor is not connected.

    Make sure the orange service plug for the hybrid battery is properly connected.
    Push it all the way in, then rotate and lock the lever, then press it to the right.
    Also, just under it is a brown part that I can't remember the name of, that will keep it
    from working if it is not properly connected.
    If the hybrid battery was dead, it would not turn over the engine.

    is the car still in the servicing company?

    are there any trouble lights?

    hello
    when I recharged the HV battery to about 50 percent months ago, the car switched to ready mode normally.
    It ran the ICE engine for about 10-15 seconds and then just checked the hybrid system. we managed to do this about 5-6 times before the battery ran out. I don't have any error codes at the moment. I will add as soon as I charge the HV battery.
    I am currently in the last charging cycle, which takes 6 hours / module. I am at the 10th module. :)

    Hello, after charging the battery, Ice still not working. So I removed the valve cover with a friend. They removed the spark plugs and checked the timing chain to see if they were set correctly and the error was found. The service that only does WV group cars noticed more marks on the exhaust cam wheel, see the picture. After a complete disassembly, comparison and resealing outside :-( my friend and I put it right, the Toyota is like new again. :) Knowing that, I'll do it myself in the summer. Well, whatever. At least the HV battery is properly serviced. My mileage is 380 thousand km.

    Wow, not even close.
    If everything was set correctly, then the timing cover was installed, then the
    chain tensioner was installed, you need to rotate the crank 720 degrees and check
    the timing makes on the cam's.
    The special links won't be there, but the cams SHOULD be on their marks.
    Unless you want to rotate the crank 30 times....

    Glad you got it running!

    A hv battery from 2010 that will sit for 8 month without being driven with 380,000 kms, that should start right up.
