The TPMS sensor is pre-programmed (already coded), meaning it comes with its specific ID code ready to go. Reset or Relearn: After installing the sensor, perform a reset or relearn process. This process ensures the car’s ECU recognises and connects with each sensor on the correct tire. Device Activation: A device is used by the fitter to activate each sensor. This lets the car’s ECU (Engine Control Unit) read the sensor data from each tire correctly.
