Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When replacing the tire pressure warning ECU, read the IDs stored in the old ECU using a Techstream and write them down before removal.
  • It is necessary to perform registration (See REGISTRATION  ) of the transmitter IDs into the tire pressure warning ECU after the ECU has been replaced.
  1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES) 
    1. Turn the ignition switch off.
    2. Connect a Techstream to the DLC3.
    3. Turn the ignition switch to ON and turn the tester on.
    4. Enter the following menus: Chassis / Tire Pressure Monitor/Data List/
    5. Check the values by referring to the table below.

      min.: 0
      max.: FFFFFFF*      		 The ID No. registered in the transmitter ID1 is displayed *: Displayed only when the ID No. is not registered.
      Registered ID2 Code Registered ID2 code/
      min.: 0
      max.: FFFFFFF*      		 The ID No. registered in the transmitter ID2 is displayed *: Displayed only when the ID No. is not registered.
      Registered ID3 Code Registered ID3 code/
      min.: 0
      max.: FFFFFFF*      		 The ID No. registered in the transmitter ID3 is displayed *: Displayed only when the ID No. is not registered.
      Registered ID4 Code Registered ID4 code/
      min.: 0
      max.: FFFFFFF*      		 The ID No. registered in the transmitter ID4 is displayed *: Displayed only when the ID No. is not registered.

      OK: 

      The registered transmitter ID codes are displayed on the tester screen. 

    NG: Go to step 2 

    OK: REPLACE TIRE PRESSURE WARNING ECU (See  TIRE PRESSURE WARNING ECU   ) 

  2. PERFORM REGISTRATION (TRANSMITTER ID) 
    1. Register the transmitter IDs for all the wheels (See REGISTRATION  ).
  3. CONFIRM TIRE INFLATION PRESSURE (DATA LIST) 
    1. Turn the ignition switch off.
    2. Connect a Techstream to the DLC3.
    3. Turn the ignition switch to ON and turn the tester on.
    4. Enter the following menus: Chassis / Tire Pressure Monitor / Data List /
    5. Check the values by referring to the table below.

      max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2 , 92 psi), Relative pressure / 537.5 kPa (5.4 kgf/cm2 , 78 psi)      		 Actual tire inflation pressure If 0 kPa (0 kgf/cm2 , 0 psi) is displayed for absolute pressure or -100 kPa (-1 kgf/cm2 , -14 psi) is displayed for relative pressure, data has not been received.*
      ID4 Tire Inflation Pressure ID4 tire inflation pressure /
      min.: Absolute pressure / 0 kPa (0 kgf/cm2 , 0 psi), Relative pressure / -100 kPa (-1 kgf/cm2 , -14 psi)
      max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2 , 92 psi), Relative pressure / 537.5 kPa (5.4 kgf/cm2 , 78 psi)      		 Actual tire inflation pressure If 0 kPa (0 kgf/cm2 , 0 psi) is displayed for absolute pressure or -100 kPa (-1 kgf/cm2 , -14 psi) is displayed for relative pressure, data has not been received.*
      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 it.
