WHOA NELLIE

I don't want to put words in Patrick Wong's mouth; but I am reading his posts and he seems to be saying he would not bet it is the traction battery -- yet.

He may have changed his mind after you posted the DTC, but maybe not. In another thread he mentions

"DTC P0A80 is logged by the battery ECU. It is possible that ECU is at fault."

Irregardless, ignoring the traction battery for the moment, he seems to be saying your 12v needs replacing based on the voltage measurements you cited. And, I think he did mention replace the 12-volt before doing anything else.

Mr. Wong, If I AM wrong about what you posted, I apologize. But, seeming that Mr. Wong thinks a 12v is needed anyway, I would go along with his advice and replace it first -- you need it anyway.

Who knows, all your problems could be solved without messing with the traction battery. From the many posts I have read, the Prius will throw lots of strange lights, etc. if the 12v is not up to par.

Just seems the logical way to go about it. To me, anyway.

Finally, and then I will shut up --- I read this on another forum -- don't know how true or not -- it is.

Thanks for your post Steve. I had a friend check the 12V battery again and it seems fine, no need to change it. As for the other stuff, it's beyond my level at this point. I have a plan of action at this point and I will post about it when I finish. It's hard for me to get to this forum everyday because my little very compromised Acer notebook cannot handle something on the PriusChat website. It just takes forever for anything to load. Anyway, thanks for your thinking on this!!!
