Does anyone know what the specifications are on the TPMS? With stock tires what pressure is the system set for? Is ita range or does it look for a specific PSI? The loss of How may PSI will trigger an alarm? Does the system monitor temperature? If so how many degrees +/- will trigger an alarm? Are the specs documented anywhere? Perhaps I have overlooked it but can't seem to find them anywhere. Any and all help will be appreciated.
