| 发明名称 | Aftermarket exhaust detection | ||
| 摘要 | A vehicle includes an exhaust system, and a plurality of active exhaust valves configured to modulate an exhaust flow through the exhaust system. A controller is configured to detect an ignition state of the vehicle, determine whether any of the plurality of active exhaust valves has malfunctioned, and, upon determining that all of the plurality of active exhaust valves were operating normally when the ignition state transitioned from a first on state to a first off state and that all of the plurality of active exhaust valves have malfunctioned when the ignition state transitions from the first off state to a second on state, enable normal operation of an engine of the vehicle. | ||
