Have Toyota Questions? Ask a Mechanic for Answers ASAP
Do you have the freeze-frame data that would be associated with the P3023 code? D you have the voltage data available for each one of the battery blocks in the hybrid battery? It would be with the freeze-frame data.
If you have the vehicle identification number and they ran a complete health check I can find that information. Can you post the vehicle identification number?
As soon as I get back from lunch I will look into this and get back with you with more information.
The only information that showed up on the data list was the code numbers. The freeze-frame data was not in the system. The bot***** *****ne is here the only way the P0A80 code will set along with the P3023 code (which means the voltage in battery block number 13 is below spec) is if the voltage in one of the battery cell modules varies by more than .1 to .2 V. The battery modules have to sustain or maintain equal voltages. If one module packet is too low by more than that tolerance it will set this code. Unfortunately Toyota does not offer individual battery packs or modules. The dealership will only replace the entire battery assembly. I would contact the people that you purchased the battery from the aftermarket and see if there's anything they can do for you to warranty or replace it. If you have the dealership print out the data list for the freeze-frame information from that particular code you will be able to look down the different battery modules and it will list the battery voltages. They should be all within .1 volts of each other that I listed.
