INSPECTION PROCEDURE

NOTICE:
  1. When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.
  2. It is necessary to perform initialization (Click here) after registration (Click here) of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU and/or one of the valve and transmitters has been replaced.
1.CHECK FREQUENCY RECEIVING CONDITION

  1. Check that the vehicle is not located in an area such as described below:

    1. Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.

      HINT:
      If the vehicle is located in an area such as the one described above, the tire pressure warning light may come on after blinking 1 minute only in a particular area due to interfering radio frequencies.

    2. Devices using similar radio frequencies are used in the vehicle.

      OK:
      Facilities or devices that use similar radio frequencies are not located in the vicinity of the vehicle.
      HINT:
      Radio transmissions may be interrupted due to the surroundings, or devices installed by the user.

3.CONFIRM TIRE INFLATION PRESSURE (DATA LIST)

  1. Turn the engine switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the engine switch on (IG).

  1. Turn the GTS on.

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

  1. Check the values by referring to the table below.

    HINT:
    1. *: It may take a few minutes until the values are displayed.
    2. 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 degrees. Then rapidly release the tire pressure and recheck the data.
    3. The wheel position cannot be determined from ID1 through ID5 on the Data List.
