This code means that the car's computer has found a problem with the second cooling fan that helps keep the battery pack cool. It's like when a fan in your room stops working and the room gets too hot.
The P0A96 code is triggered when the vehicle's control module detects an issue with the electrical circuit of the second cooling fan for the hybrid or electric vehicle's battery pack.
The P0A96 code indicates that there is an open circuit or a fault in the control circuit of the second cooling fan responsible for cooling the hybrid or EV battery pack. This could be due to a wiring issue, a faulty fan motor, or a problem with the control module.
• Check Engine Light is on
• Reduced battery performance
• Overheating of the battery pack
• Faulty cooling fan 2
• Open or shorted wiring in the cooling fan circuit
• Faulty control module
OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics in vehicles.
Cooling Fan: A fan used to cool the battery pack in hybrid and electric vehicles.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the cooling fan circuit.
• Test the cooling fan motor for proper operation.
• Replace or repair any damaged wiring or connectors.
• Replace the faulty cooling fan.
• Replace the control module if necessary.

• Regularly inspect the cooling fan system.
• Ensure proper maintenance of the vehicle's electrical system.
• Avoid high temperatures that could stress the battery pack.
Control Circuit Issue
• Avoid driving the vehicle until the issue is resolved to prevent battery damage.
• Consult a professional mechanic for diagnosis and repair.
Check with your vehicle manufacturer as hybrid components may have extended warranties.
This code has become more common as hybrid and electric vehicles have increased in popularity, highlighting the importance of battery cooling systems.
High – It is important to address this issue promptly to prevent potential battery damage.
Driving with an overheated battery can cause safety issues. Always ensure your vehicle is safe to operate.
• Vehicle is in operation
• Battery pack temperature is elevated
The cooling fan is typically located near the hybrid or EV battery pack, often in the rear of the vehicle.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to battery overheating, reduced performance, and potential damage to the battery pack.
Q: Can I drive my car with this code?
A: It is not recommended to drive the vehicle until the issue is resolved, as it could lead to further damage.
