I'm guessing when you had your winter wheels put on, the tire shop added the correct TPMS sensors to your winter wheels. Otherwise you would of had a TPMS fault all winter. These are then programmed to the vehicle.
In this case, all you need to do is reprogram the sensors back to the Body Control Module. This requires a TPMS tool. But I bet if you go to the tire shop that installed them, they'll do it for free. It only takes 1 minute with the TPMS tool.
