A vehicle electronic control unit includes a power input port, which receives electric power from a vehicle battery, and a power output port, which provides electric power to a vehicle electronic device including an antenna. The electronic device receives data transmissions from a vehicle sensor. The power output port provides substantially uninterrupted electric power from the vehicle battery to the vehicle electronic device. A communication port is electrically connected to a vehicle communication bus. The communication port receives data transmissions from the vehicle electronic device via the communication port. An electronic component, electrically connected to the communication port, is initially in a first state when a vehicle ignition is off. The electronic component, while in a second state and while the vehicle ignition is off, receives additional data transmissions from the vehicle electronic device indicating statuses of respective vehicle sensors.
