    I found the ID
    2014
    Does it need to be updated?

    Depends. What car is your id from? A 2012 as in your profile, a 2014 in your post, a hatchback, plug in or v wagon?

    The registration period is only until 2012. I will see if I can modify it.

    I believe the latest calibration ID for your 2014 Prius is 34754200. It does not need to be updated. Your car will still run with the "old" calibration ID, but you might want to have it updated to make you feel better knowing that you have the latest and greatest update.

    I had my 2011 Prius updated three years ago, as noted in post #5.
