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 works on 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 if aftermarket sensors with the wrong frequency are installed. Widely used: Fits most GM vehicles equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system. Effect: The EL-50448 TPMS reset tool helps reprogram all tires easily in 3 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, removing tire pressure alarms, or exchanging tires. Works on most General Motors vehicles (Chevy, Opel) equipped with 315 or 433 MHz TPMS sensors.
