Sensor Functions using pressure increase/decrease method
Each sensor takes a pressure measurement sample once every 20 seconds while in stationary mode. If the tire pressure increases, or decreases by more than 11 kPa (1.6 psi) from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If a pressure change has indeed occurred, the sensor sends a re-measure transmission to the PDM. When the PDM receives a re-measure transmission while in sensor learn mode, it will assign that sensor ID to that location on the vehicle.
