P0D20 SATURN Meaning

The hybrid/EV powertrain control module 2 monitors the battery charger high-voltage output and current output and ensures they are within the proper range. The battery charger operates in either a constant current mode or a constant voltage mode. Whichever mode you are in will determine which diagnostic will be run.
