Hello! My son's TPMS light came on a few days ago which was to be expected since we had our first cold morning of the season. He tested the pressure all around and all seemed okay. He just had his winter tires put on at a garage and as he was driving out the warning came on for 3 of the 4 tires, with the "stop safely" message. He checked the pressure, all is good. Is there a quick 'reset' he can do? Is this a failure that needs to be fixed? Thanks!
