Tire Pressure Monitoring (TPM) Transponder - Description

DESCRIPTION

A transponder, sometimes referred to as a trigger module, is located in three of the four wheel wells (behind the wheelhouse splash shields) of a vehicle equipped with Premium TPM. These transponders are used to provide the Wireless Control Module (WCM), commonly referred to as the Sentry Key Remote Entry Module (SKREEM), with the location of the tire pressure sensors on the vehicle. 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. On this vehicle, there is a transponder located in the left front, left rear, and right rear wheelhouse. There is not a transponder located in the right front wheelhouse.
