I have a TPMS relearn tool that worked fine on our 2016 Trax and 2017 Silverado, but we traded in the Trax and bought an Envision Essence. Installed a new set of winter wheels and tires with another set of TPMS sensors. It seems the computer is different, does anyone know what the compatible frequencies are for the '21 Envision, and link to relearn tool that will work? Thanks!
