    Sure, as for the P0A08 or 80 I think I mixed those numbers up sorry. If there is an P0A08 that is a new one for me. I assume it is an old code since I didn't erase it when I played with the hybrid battery and in viewing the modules they were all consistent in the voltages where they are happy. But I guess anything can happen when these cars get into higher miles. I am going to keep digging as that high pitch alarm tone meant something.
