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: The tire pressure sensor on models from 2012 and later can be read only with certain specified diagnostic tools. Compatible: Works on all General Motors vehicles manufactured with a 315 or 433 MHz TPMS system. Will not work with aftermarket sensors that are not matched to the correct frequency. Widely used: Fits most GM vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system. Function: The EL-50448 TPMS reset tool simplifies reprogramming all tires in 3 steps. The tire pressure monitor sensor activation tool is easy to use and activates individual TPM sensors with the press of one button. Essential for replacing tire pressure sensors, resetting tire pressure alarms, or exchanging tires. Works on most General Motors vehicles (Chevy, Opel) equipped with a 315 or 433 MHz TPMS sensor.
