Hello, I have a 2012 Lexus CT200h and I'm getting trouble codes P0B42, C1259, and C1310. I have replaced the 12v battery, I have replaced the hybrid battery voltage sensor. The voltages of the cells range from 7.6-7.96. I'm not sure what else to do other than replacing the entire hybrid battery assembly. Any help would be appreciated. Thank you

I have the service manual software in the engine and tech sub forum. It will give you the causes and diagnostics procedures for each code.

Thanks but I already have the repair manual. I’m still stuck. I don’t really want to make the expense of buying the entire battery and still having the problem. That’s why I’m trying to exhaust every other possible solution.

Doctor Prius application will help you to check
Your battery.
Do you live near the sea or humid area?
It might cause your battery connections
To accumulate corrosion?!
