Tire Pressure Warning System: Initialization

  1. DESCRIPTION OF INITIALIZATION 
    1. Perform initialization in the following cases:
      • Before delivery of a new vehicle.
      • After replacement of the tire pressure warning ECU*.
      • After a tire rotation (for 4WD models).
      • After replacement of any of the tire pressure warning valve and transmitters*.
      • After a different size or type of tire is fitted.

      *: Perform initialization after transmitter ID registration is completed (See REGISTRATION ).

    2. Before initialization
      1. Set all tire pressures to the specified value (s) (See TIRE PRESSURE WARNING SYSTEM ).
    NOTE: Make sure the tires are cold.
  2. INITIALIZATION PROCEDURE 
    1. Adjust all tire pressures to the standard tire inflation pressure, as indicated on the tire and loading information label on the vehicle.
    2. Turn the ignition switch to ON.
    3. Push and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.

    4. Turn the ignition switch off.
    5. Connect the Techstream to the DLC3.
    6. Turn the ignition switch to ON.
    7. Turn the Techstream on.
    8. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
    9. Check that initialization has been completed.
    10. Confirm that tire pressure data of all wheels are displayed on the Techstream.
      NOTE:
      • Initialization normally completes within 2 or 3 minutes.
      • If initialization did not complete successfully, DTC C2177/77 will be set after a vehicle speed 8 km/h (5 mph) or more continues for 20 minutes or more.
      • Initialization can be terminated by connecting terminals TC and CG of the DLC3.

HINT:
  • The initialization is completed when the "ID Tire Inflation Pressure" display shows the correct pressures.
  • *: It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (See INSPECTION PROCEDURE  ).
