    I have the b1412 and u0141 code. Why are the ac and the smart key code on my Prius 09? Any ideas? Also I have the tire pressure light on.

    Here is the workup for DTC B1412 : 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/cib14121.pdf

    If the tire pressure light is lit, then you have an issue with one or more of the TPMS sensors.

    Well that accelerated rather quickly. It only took you a couple of minutes for that workup, which has to be a shop record :whistle:

    Hard to say how much, you should ask the dealer. Some have reported 6k+ for an 'ac replace', with parts totaling around 3k+.

    You could DIY and save a bunch, but you may have to remove and replace most of the dash depending on your 'ac replace'

    Here are a couple of pictures to help give you an idea of what one 'ac replace' entailed. Though yours could be easier.

    yes, but make sure they have hybrid a/c high voltage experience. many systems have been ruined by 'pro's' who don't have the knowledge or understand the differences.

    No. If you were having symptoms, you would know. Just ignore codes with no symptoms
