Hybrid Battery Pack Cooling Fan 2 Control Circuit/Open
The P0A96 code indicates an open or malfunction in the control circuit of the hybrid battery pack cooling fan 2. This fan is critical for maintaining optimal temperature of the high-voltage hybrid battery. An open circuit means the electrical path is broken, preventing the fan from operating when needed, which can lead to battery overheating and reduced performance.
