P0A0D KIA Code - High Voltage System Interlock Circuit High
Quick Answer
The Battery Management System Control Unit (BMS-ECU) sets P0A0D when the Safety Plug, which powers to the High Voltage Battery is in an off state or removed, the bus bar which connects the battery cell in series is open or the 125A/DC 450V capacity fuse which is installed to the internal of safety plug is melted. Common causes include The hybrid battery Safety Plug, The hybrid battery main relay, Faulty Battery Management System Control Unit (BMS-ECU). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
