    So I'm helping this guy diagnose his car and it's apparent he needs a new HV battery. He had someone replace 3 modules but it's still coming up with p0a80 and p3018. Those I can understand but he's also getting p0AA4.

    Whoever did his module swap probably didn't balance everything or didn't swap in good modules. Whatever the case, he has to do it all over again.

    What is P0AA4?
