    3.ADJUST TIRE PRESSURE*

    1. Turn the ignition switch off.

    2. Set the tire pressure to the specified value (YARIS_NCP93 RM000000OQN01OX.html).

    3. Connect the Techstream to the DLC3.

    4. Turn the ignition switch to ON.

    5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

    6. Read the "ID Tire Inflation Pressure" values.

    7. Check the Data List (YARIS_NCP93 RM000000XMY06RX.html).

      HINT:
      1. It takes a few minutes to display the updated tire pressure data.
      2. If the problem is that the tire pressure decreases, wait until all of the tire pressure data is received by the ECU. If the data is received, the tire pressure warning light will go off.
