P0A98Hybrid/EV Battery Pack Cooling Fan 2 Stuck On

P0A98 indicates that the hybrid or electric vehicle battery pack cooling fan 2 is stuck on, meaning the control module commanded the fan to stop but the fan continued running or the circuit remained energized. The computer detects this by monitoring the fan control circuit and seeing an unexpected continuous current draw or lack of response to the off command.
