For vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system, a "Sensor Re-Learn Procedure" must be performed after tire rotations, Remote Control Door Lock Receiver Module replacement, or Tire Pressure Sensor replacement. This re-learn procedure can be performed using a special tool: EL-50448. Also compatible with 2014 models. The tire pressure sensor on models from 2012 and later can be read only with certain specified diagnostic tools. Compatible with all General Motors vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring System (TPMS). Not compatible with aftermarket sensors that operate at the wrong frequency. Widely used for most GM vehicles equipped with a 315 or 433 MHz TPMS. Function: The EL-50448 TPMS reset tool simplifies reprogramming all tires in three easy steps. The tire pressure monitor sensor activation tool is user-friendly and activates individual TPM sensors with the press of a button. Essential for replacing tire pressure sensors, resetting tire pressure alarms, or exchanging tires. Works on most General Motors vehicles (including Chevrolet, Opel) equipped with 315 or 433 MHz TPMS sensors.
