Code P0D43 Buick Description

The battery charger control module will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is communicated from the battery charger control module to the hybrid powertrain control module 2 through serial data. The hybrid powertrain control module 2 is the host controller for diagnostic trouble code (DTC) information.
The DTC for the battery charger control module is internal measurements that verify the charger is performing properly. The battery charger control module measures internal voltages, currents, and temperatures and verifies they are within the proper range.
