    Hello!

    Going through the flow chart of P0A94 / 555 for 2005 Prius.

    I'm confused when It comes to the formula on step 5 & 6, I don't get it. Temperature at the time of measurements was 17c.

    Hybrid Vehicle Motor resistance:
    U - V: 128.4
    V - W: 128.2
    W - U: 128.3

    Hybrid Vehicle Generator resistance:
    U - V: 104.5
    V - W: 104.1
    W - U: 104.3

    Everything checks out and is good for the insulation test and voltage test on the inverter stop test. So far, I'm going with the inverter being toast. :eek:.... Forum won't allow me to post the link to the Charm li diag for this.
