The P0D21 fault code indicates that the battery charger output voltage in the hybridEV powertrain control module 2 is too low. This means that the battery charger is not providing the necessary voltage to charge the battery properly.

When this fault code is triggered, the powertrain control module and battery charger control module monitor the high-voltage output and current output of the battery charger. They ensure that the voltage is within the correct range and that there is no resistive short in the charging bus. If the voltage is found to be too low, it can lead to insufficient charging of the battery, which can result in reduced performance and potential issues with starting the vehicle.

It is important to address this issue promptly to avoid further damage to the battery and ensure optimal functioning of the hybrid or electric vehicle.
