"TPMS Transmitter Check" Method

According to the following procedures, identify which registered TPMS transmitter corresponds to which wheel, and check the tire pressure and acceleration value of each TPMS transmitter.

1. Check the data list "Air Pressure, Tire1, 2, 3, 4" and write down the tire pressure for all wheels.
   NOTE: The display at this time is the data received most recently.
2. Perform the following procedures for four wheels in order, identify the wheel by checking the tire pressure of each wheel.
   1. Change the pressure of tire for 20 kPa (2.9 psi) or more so that the TPMS transmitter sends the latest sensor data (The tire pressure can either be decreased or increased).
   2. Check the data list screen to determine which tire number corresponds to the wheel whose tire pressure has changed.
      NOTE:

      • It may take approximately one minute that the data of tire pressure change is displayed on the M.U.T.-III screen.
      • If the data of tire pressure change is not displayed on the M.U.T.-III screen, the most possible cause is that the radio wave sent from the TPMS transmitter cannot be received. In this case, the radio wave may be received by performing the procedures from (1) again after turning the tire to change the TPMS transmitter position. If the tire pressure change is still not displayed on the M.U.T.-III screen, the TPMS transmitter in which the ID code is not registered may be installed, or the TPMS transmitter may be faulty. Therefore, perform ID code registration or replace the TPMS transmitter according to the instructions of troubleshooting for DTCs. (At this time, do not register the ID codes or replace the TPMS transmitter.)
3. Check the tire pressure or acceleration value shown in the screen (if needed).
4. After checking by the tire pressure change, adjust the checked tire pressure to the proper value.
