    Hello, priuschat. The battery modules in my HV battery were getting weak. As a precaution I drained my HV battery. My discharger was damaged so I did this by putting it in neutral. I then pulled the HV battery pack out and replaced all modules with 2017 prius modules. I also used brand new bus bars. According to what I see in doctor prius app (attached), I think the install went well except for the p3004. It's looking like an inverter issue since the 12V battery isn't charging now. I checked all the fuses and they were Ok. Is there anything else I should look for? Thanks! Screenshot_20240707_203859_Dr%20Prius.jpg Screenshot_20240707_193111.jpg

    Almost forgot to mention that it won't go into reverse or drive. And the engine won't start in maintenance mode...
