So today I go back in my jeep after not driving it for a few days and I have a "Service Tire Pressure Monitoring System" message that comes up, or something along those words. When you go to view the tire pressure in the dash the tires are just marked out red, with dashes instead of pressure readings, and of course the tire caution light is light up in the tach gauge cluster as well. I have restarted the jeep several times today and have it's still not working. I'm taking my jeep to the dealership for something else soon anyway so I was going to have it looked at then, just curious if anyone had any insight. I am running stock tires and rims, have not changed anything with them.
