I don't know if they broadcast (they might), but the function I know they perform is to receive the signal from the TPMS sensors that are in the wheels. The two front TPMS sensors are in the front part of the front wheelwells. I believe that the two rears are in the rear part of the rear wheelwells per the illustration. I have actually replaced a front so I know where they are but am just going by the illustrations for the rear. As far as the spare, it is a mystery. It has to be mounted somewhere in the proximity of the spare wheelwell in order to pick up the TPMS signal from the wheel, but that's all I know.As I understand it, the “antenna’s” you are referring to are only for brodcasting a signal to the tpms sensor and dictate when they broadcast the pressure. Per the rave the receiver is located above the front map light console.
That does not make sense to me. The TPMS sensors are the only thing in the car that know what the pressure in the tires are. They have to transmit this information to the car in order for the car to know if the pressure is correct. If the antenna sends data to the TPMS sensors, how does the system get tire pressure information? The Tire TPMS sensors must transmit.Per the rave the control module is in the right rear. The “antennas” you are referring to send a signal to the tpms sensors in your wheels and do not receive. The receive antenna is located above the map lights, again per the rave manual. There is no initiator antenna for the spare sensor.
I am looking for a good TPMS diagnostic tool that works with this car.You need a diagnoatic tool to diagnose, unlikely that the antennas are bad. Most likely fault is the tpms module in the right rear. A good tire shop can test the sensors for battery life/function. Are you getting a notice along with the light and if so which notice? If it where a faulty sensor it would tell you which one.
