Hybrid battery internal resistance in Dr Prius app
PriusChat member johnjohnchu made this handy Gen 2 block numbering picture: So, assuming Dr. Prius numbers the blocks the right way, the service plug is included in block 10, so it wouldn''t correspond to what you''re seeing at blocks 4 and 5. If Dr. Prius has the numbering backward, then block "5" would be the one with the service …
