Code P0D3A Cadillac Description

The P0D3A diagnostic trouble code (DTC) for Cadillac vehicles refers to the Battery Charger Input Current Sensor Circuit Low Voltage. This code indicates that the vehicle's onboard computer has detected a low voltage condition in the battery charger input current sensor circuit. The battery charger input current sensor is responsible for monitoring the current flowing into the vehicle's battery during charging. When the voltage in this circuit drops below the specified threshold, the P0D3A code is triggered.
