Code P0D49 Cadillac Description

The P0D49 diagnostic trouble code (DTC) for Cadillac vehicles indicates a problem with the Battery Charger 14 V Output Current Sensor Circuit, specifically detecting low voltage. This code is typically found in hybrid or electric vehicles that utilize a high-voltage battery system. The Battery Charger 14 V Output Current Sensor is responsible for monitoring the current flow from the charger to the battery, ensuring that the correct voltage is being delivered for charging. When the sensor detects low voltage, it triggers the P0D49 code, indicating a potential issue with the charging system.
