Dealerships have a tpms tool to program new sensors. You can also buy 3rd party sensors from online tire shops. They just need programmed by a dealership so the ecu recognizes them.
its only my winter setup, i refuse to buy another set of sensors, plus pay the ripoff dealer 100 to program them. maybe if it was a more reasonable charge.
i just let the chime go off, its only when you first start the car.
and you cant turn the traction control off. but oh well
