Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: It is necessary to register the transmitter IDs after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ECU (See REGISTRATION  ).
  1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES) 
    1. Set the tire pressure of all the wheels to the specified value (See TIRE PRESSURE WARNING SYSTEM  ).
    2. Turn the ignition switch OFF.
    3. Connect the Techstream to the DLC3.
    4. Turn the ignition switch on (IG).
    5. Turn the Techstream on.
    6. Check the values by referring to the table below. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

      Tire Pressure Monitor:

      min.: 0
      max.: FFFFFFF (*1)      		 The ID No. registered in the transmitter ID4 is displayed -
      Registered ID5 Code Registered ID5 code/
      min.: 0
      max.: FFFFFFF(*1)      		 The ID No. registered in the transmitter ID5 is displayed -
      HINT:
      *1: Displayed only when the ID No, is not registered.
    7. Check the ID No. on the identified transmitter by removing it from the tire and wheel.

      OK: The registered transmitter ID codes are displayed on the Techstream display. 

    NG: Go to step 2 

    OK: REPLACE TIRE PRESSURE WARNING ECU  (See REMOVAL  )

  2. PERFORM REGISTRATION (TRANSMITTER ID) 
    1. Register the transmitter IDs for all the wheels (See REGISTRATION  ).
  3. READ VALUE OF TECHSTREAM (TIRE INFLATION PRESSURE) 
    1. Turn the ignition switch OFF.
    2. Connect the Techstream to the DLC3.
    3. Turn the ignition switch on (IG).
    4. Turn the Techstream on.
    5. Check the values by referring to the table below. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

      HINT:
      • *1: 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 degrees. Then rapidly release the tire pressure and recheck it.
