This summary uses the existing diagnostic information shown in full below.
This code means that the battery in a hybrid or electric car is getting too hot and the car is reducing power to prevent damage.
The vehicle's control system has detected that the temperature of the hybrid or electric vehicle's battery module 'A' is too high. To protect the battery and vehicle, the system reduces power output.
The P1BB3 code is triggered when the Battery Management System (BMS) detects that the temperature of battery module 'A' exceeds the predefined threshold. This can lead to a power reduction to prevent overheating and potential damage to the battery cells.
• Reduced vehicle performance
• Warning light on the dashboard
• Possible overheating smell
• Faulty battery temperature sensor
• Cooling system malfunction
• Battery module degradation

Battery Management System Issue
• Avoid driving aggressively to prevent overheating.
• Seek professional inspection if the warning light appears.
Battery-related issues may be covered under the vehicle's warranty, especially if the vehicle is still under the manufacturer's warranty period.
This code has become more prevalent with the increase in hybrid and electric vehicle usage, highlighting the importance of battery temperature management.
High – Immediate attention is required to prevent potential battery damage.
Operating a vehicle with an overheated battery can be dangerous and may lead to further damage or safety hazards.
• Vehicle at operating temperature
• Battery under load
The battery module is typically located under the vehicle floor or in the rear compartment.
Q: Can I drive with a P1BB3 code?
A: It's not recommended to drive with this code active, as it indicates a potential overheating issue with the battery.
Q: How can I prevent battery overheating?
A: Ensure the cooling system is functioning properly and avoid exposing the vehicle to extreme temperatures.
