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 has been replaced.
  1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES) 
    1. Turn the ignition switch off.
    2. Connect Techstream to the DLC3.
    3. Turn the ignition switch on (IG) 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.: FFFFFFF*    		 The ID No. registered in the transmitter ID5 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 REMOVAL )

  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 Techstream to the DLC3.
    3. Turn the ignition switch on (IG) 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.

    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°. Then rapidly release the tire pressure and recheck the data.
