   HINT: 

   *: It may take about 2 or 3 minutes until the values are displayed.

7. Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm² , 5.8 psi) within 30 seconds.
8. Check the Data List.
   NOTE:

   • It takes about 2 or 3 minutes to display the updated tire pressure data.
   • When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck it.
   • Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.
9. After confirming that the "ID Tire Inflation Pressure" data for one tire (ID1 to ID4) has changed, repeat this procedure one by one. Identify the transmitter not received.
