    Hello,
    I discovered the third battery that requires the most attention while working on my 2001 Prius. Pay very close attention.:)
    When I began diagnosing my HV battery pack I discovered their was a 9 volt battery located inside my volt meter.
    Needless to say, my readings were all off because my 9volt was low.
    I had module readings of 9.4 - 10.5 !!!
    After changing the 9v battery the readings were 7.75 - 8.1
    Have a great day!
    Joe

    Very good point :) Reminds me to check my DVM battery before using it again.
