Inspection Procedure

NOTE:
  • When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using Techstream and write them down before removal.
  • It is necessary to perform initialization (See INITIALIZATION ) after registration (See REGISTRATION ) of the transmitter IDs into the tire pressure warning ECU if the ECU and/or any of the valve and transmitters have been replaced.
  1. IDENTIFY TRANSMITTER NOT RECEIVED 
    1. Set the tire pressure to the appropriate specified values (See TIRE PRESSURE WARNING SYSTEM ).
    2. Turn the ignition switch off.
    3. Connect Techstream to the DLC3.
    4. Turn the ignition switch on (IG) and turn the tester on.
    5. Enter the following menus: Chassis/Tire Pressure Monitor/Data List.
    6. Check the values by referring to the table below.

      HINT:
      (1) It may take about 2 or 3 minutes until the values are displayed.
    7. Rapidly reduce the tire pressure for each wheel by 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 the "ID Tire Inflation Pressure" data has not 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.
      • 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 ID5) has changed, repeat this procedure one by one. Identify the transmitter not received.
