DTC codes / P0Axx · Hybrid propulsion / P0AD6
P0AD6 indicates that the hybrid or electric vehicle battery pack air flow valve A control circuit is not performing within its expected range, meaning the battery energy control module has detected an abnormal electrical condition in the circuit that commands the valve. The valve regulates cooling air flow across the high-voltage battery pack, and the module monitors the circuit for opens, shorts, or unexpected voltage drops when activating the valve.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
