The P0A96 fault code indicates an issue with the Hybrid Battery Pack Cooling Fan 2 Control Circuit. This error can arise when there is an open circuit or a malfunction in the cooling fan's control system. Proper cooling of the hybrid battery is essential for optimal performance and longevity, and any interruptions in the cooling process can lead to battery overheating and reduced efficiency.

• The cooling fan plays a crucial role in maintaining the temperature of the hybrid battery pack.
• An open circuit in the control can prevent the fan from activating, leading to overheating issues.
• This fault code should be addressed promptly to avoid further damage to the battery system.

What are the symptoms of the P0A96 code?

Drivers may notice several symptoms when the P0A96 fault code is triggered:

• Dashboard warning lights illuminated, indicating a problem with the hybrid system.
• Overheating of the hybrid battery, potentially leading to reduced electric vehicle range.
• Unusual noises coming from the vicinity of the battery pack or cooling system.
• A noticeable decrease in performance of the hybrid vehicle under load, especially in hot weather conditions.

What causes the P0A96 code?

The P0A96 fault code can be caused by several factors, including:

• A defective Hybrid Battery Pack Cooling Fan 2.
• Wiring issues such as frayed or damaged cables in the cooling fan circuit.
• A blown fuse or relay within the electrical circuit that controls the cooling fan.
• Faulty temperature sensors that prevent the fan from receiving the correct signals.
• Computer software issues that may cause erroneous readings or control failures.

How to fix P0A96?

To resolve the P0A96 fault code, technicians typically follow these steps:

• Inspect the wiring and connectors associated with the cooling fan circuit for any signs of damage.
• Test the Hybrid Battery Pack Cooling Fan 2 for functionality, replacing it if necessary.
• Check related fuses and relays in the fan control circuit and replace any that are blown.
• Verify the signals from the temperature sensors to ensure they are functioning properly.
• Reset the vehicle's control modules and clear the fault codes after service is performed.
