For GM 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 by using special tool EL-50448.
Works on all General Motors (Buick, Cadillac, Chevrolet, GMC) products manufactured for the North American market. It won't work if you've purchased aftermarket sensors that are the wrong frequency.
