    Hi everyone so just a little info my car is a 2005 Prius 150k miles. The other day got this code no other sub codes.I have reset the codes a few times still pops up.So my options are replace with a new Toyota battery found a dealer selling for $1950 or change the bad module which I believe is only 1 bad module I will be attaching a screen shot of the torque voltages.Anyways was wondering what you guys would do change the whole battery or just the module this thing is stressing me out thanks

    if you plan on keeping the car, a new battery will solve the problem for a long time.

    replacing cells is likely going to be an ongoing exercise, but if you have time, much cheaper.

    there's lots of good rebuilding threads here if you're interested in learning the best methods and pitfalls

    Your data shows a bad module in block #12.

    Based on forum posts, you might have a 10% chance that "just" replacing a module will actually work and might get you 6-12 months.

    Do a bunch of research on the forum, buy some gear and used modules and you can "refurbish" your pack. Do everything right and you can get 2-3 years. Do it wrong and it won't work at all.

    Buying a "rebuilt" pack is a crapshoot. Might last 2-3 years, might last 2-3 months (or weeks). Understand the warranty because you will likely need it.

    New battery from Toyota is the most reliable path.
