This summary uses the existing diagnostic information shown in full below.
The car's computer noticed that the battery is getting too hot, so it is asking the car to slow down and go into a safe mode to prevent damage.
This code indicates that the temperature of the hybrid or electric vehicle battery has exceeded a predefined threshold, triggering a request for the vehicle to enter a 'limp home' mode to prevent damage.
The vehicle's battery management system monitors the temperature of the hybrid or EV battery. If the temperature exceeds a certain limit, it sends a signal to the vehicle's control system to enter a reduced power mode, often called 'limp home' mode, to protect the battery from overheating and potential damage.
• Reduced engine power
• Warning light on the dashboard
• Possible overheating smell
• Faulty battery temperature sensor
• Battery cooling system failure
• High ambient temperature conditions
Limp Home Mode: A safety feature that reduces vehicle power to prevent damage.
