    OK → See step   4 

  2. PERFORM REGISTRATION (TRANSMITTER ID) 
    1. Register the transmitter IDs for all the wheels. Refer to REGISTRATION .

    NEXT: Go to next step 

  3. CONFIRM TIRE INFLATION PRESSURE (DATA LIST) 
    1. Turn the ignition switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch to ON and turn the Techstream on.
    4. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
    5. Check the values by referring to the table below.

      HINT: 

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

      Result Proceed to
      All tire pressure readings are equal to specified values. A
      Tire pressure values are not displayed. B
