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. Specified diagnostic tool required: The tire pressure sensor on models from 2012 and later can only be read with certain diagnostic tools. Compatible with all General Motors vehicles manufactured 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 a 315 or 433 MHz TPMS sensor.
