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.Also works on 2014 GM models EL-50448 Tire Pressure Monitor Sensor TPMS Activation Tool OEC-T5 The tire pressure sensor on models in & after 2012 can be read, only with some specified diagnostic tools. Before tire pressure monitoring system works normally properly, the body control module will record ID information of each position in the tire pressure sensor; and use the following methods to read the tire pressure sensor after replacing a tire or wheel speed sensor. Please refer to the specific methods as follows: EL-50448 instructions: EL50448 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. EL50448 fit for G.M most kind of vehicles, equipped with a 315 or 433 MHz Tire Pressure Monitoring (TPM) system. This re-learn procedure can be performed by using special tool EL-50448.
