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. The tire pressure sensor on models from 2012 and after can be read only with certain specified diagnostic tools.
