This summary uses the existing diagnostic information shown in full below.
This code means that the car's battery is getting too hot. It's like when your phone gets really warm after using it for a long time.
The vehicle's onboard computer has detected that the temperature of Battery Pack D in the hybrid or electric vehicle is higher than the recommended limit.
The P2D48 code is triggered when the Battery Management System (BMS) identifies that the temperature of Battery Pack D exceeds the safe operating threshold. This could be due to excessive current draw, poor cooling, or a malfunctioning temperature sensor.
• Warning light on the dashboard
• Reduced vehicle performance
• Increased fan noise from the cooling system
• Faulty temperature sensor
• Cooling system failure
• Excessive current draw from the battery
