Need some suggestions. 2016 Ram 2500 Power Wagon. Recently purchased aftermarket tires and wheels including buying new Mopar TPMS. P/N 68249197AA which are 434 Mz and advertised to fit this vehicle and pre-programmed. After replacing the stock tires and wheels and driving for awhile the tire pressure screen blanked out and just reads "--" at each wheel. I've probably driven the truck at least 100 miles since then including a 30 mile trip that was at least 11-12 miles on the freeway. I was under the impression that the truck would "learn" these new sensors but obviously haven't.
- Have to make the assumption that the tire shop actually installed these sensors when they mounted up the tires and wheels. Assuming that a shop with a TPMS tool could quickly tell if they were just dummy valve stems???
- After doing some reading I've seen reference to setting the pressure to the factory placard values (60 f, 65 r) to get them to reset. I set the pressures of the new tires below these values when I first installed them and prior to driving. Do I need to increase the pressures first and try again?
- Do I need to reset the TPMS on the truck? Was reading about a TPMS reset button under the steering wheel and after a quick glance didn't see it, but only had a quick minute to look?
- Should I just take it to the shop and have them "relearn" the sensors with the TPMS tool?
