The system can be checked using the diagnostic tool by activating a read out at the same time as activating the sensors using a special tool. The special tool is positioned against the tire, where the sensor is located, at the same time as a button is pressed on the special tool. The special tool transmits a signal that activates the sensor so that it starts transmitting signals to the central electronic module (CEM). The activated sensor's ID number and tire pressure is then shown in the display in the diagnostic tool.
