Abstract

A first data transmission and a second data transmission from a TPMS monitor are received and stored. The first data transmission and the second data transmission are compared and at least one changing portion of the data transmission is identified based upon the comparison. Sensed data is received from a tire pressure sensor. A data resolution is determined and a third data transmission formed. The at least one changing portion of the third data transmission is replaced with the sensed data according to the resolution. The third data transmission is transmitted including the sensed data.
