Tire Pressure Monitor Receiver / Transponder: Description and Operation
Operation - Premium System

OPERATION - PREMIUM SYSTEM

Transponders located in three of the four wheel wells of the vehicle provide the Wireless Ignition Node (WIN) commonly referred to as the Wireless 
Control Module (WCM) with the location of the tire pressure sensors on the vehicle. The transponders are located in the left front, right front and right
rear wheel wells. A fourth transponder is not necessary in the remaining wheel well due to the process-of-elimination theory. Once the system knows the
location of the first three sensors it assumes the location of the fourth tire pressure sensor is in the left rear tire.
