Answer 1

P0622 Generator field not switching properly

P1594 Charging system voltage too high

P1682 Charging system voltage too low

Over charging condition,This is with the EVR (electronic voltage regulator) located in the PCM, when you get these code and to resolve the charging system the PCM would need to be replaced, inside the PCM is the EVR which is a non serviceable component
