    DrPrius can only show codes from the ECM (engine/ICE) and Hybrid Control - ecu's. I am not sure if it will consistently pull codes from the HV battery ecu. That's all.

    Yes, there is something wrong with block 8. Normal "voltage diff" is 0.3V or less with low or no amps. Brief readings of up to twice that are fine. If the voltage difference is too high for too long then the battery ecu will set codes.

    Maybe one of the two battery modules in block 8 has failed. Maybe there's corrosion at the voltage sense harness connector of the battery ecu.

    Ok good. Trying to get the tools I need for Prius's. Have performed mechanic work for years and just started working on a couple prius's. Was hoping this app could read what codes that were being thrown for all these lights to appear. Someone mentioned something in another thread about a higher level "paid" portion of Dr, Prius. Didnt know what to buy....
