passenger compartment, the console antenna broadcasts a challenge within the passenger compartment to the transmitter. If the response from the
transmitter via radio frequency (RF) is a valid response, the antenna will determine there is a fob within the vehicle. If no response is received, the
antenna determines that no fob is in the vehicle.
