    Hello everyone! New member here but I have been reading through all your posts. I recently acquired my 4th Prius a 2014 model 2. I’ve never had a battery issue with any of my previous ones, but this one a 2014 with 125k miles is acting up. Shortly after buying it I got the hybrid warning pull to a safe place message! This is my first experience with Dr. Prius and if nothing else it’s great for resetting the battery codes. First thing I noticed is the center temp is much higher than the ends. I’ve also noticed the delta SOC has been 0 to 40. I’ve also noticed module #9 is always lower than the others. Check out the picture! Has anyone else seen the Dr Prius app go crazy like this?

    What high voltage battery is in your car? Original or replacement?
    I think your Dr. Prius is not set up correctly.

    What adapter is used to connect to OBDII?

    I have that happen in the past! It's either 1. bad OBD2 adapter, or 2. bad grounding/corrosion at the battery ECU causing signal noise.

    here are the two OBD2 adapters that never failed me nor any customer:
