For vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring System (TPMS), 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 by using the EL-50448 tool. Also compatible with 2014 models. Specified diagnostic tool: The tire pressure sensor on models from 2012 and after can be read only with certain diagnostic tools. Compatibility: Works on all vehicles equipped with a 315 or 433 MHz TPMS. May not function with aftermarket sensors that operate at the wrong frequency. Wide application: Fits most GM vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring System. Functionality: The EL-50448 TPMS reset tool allows easy reprogramming of all tires in three steps. The tire pressure monitor sensor activation tool is user-friendly and activates individual sensors with the press of a button. This tool is designed for replacement of tire pressure sensors, resetting tire pressure alarms, or during tire exchanges. Works on most vehicles equipped with 315 or 433 MHz TPMS sensors.
