  3. DESCRIPTION OF CODE REGISTRATION (Engine Immobilizers System) 

    HINT:

    • The ID codes are the same as recognition codes for the wireless transmitter and the engine immobilizer function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobilizer function to be operated.
    • Code registration is necessary when the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), steering lock ECU, or key is replaced with a new one.
    1. Vehicles with the smart key system do not have a key slot. Therefore, hold the key close to the power switch to register the key, as shown in the illustration below.

    6. Select the following menu items: Powertrain I Hybrid Control / Data List / State of Charge.
    7. Move the shift lever to the N position, set the A/C switch to MAX cool or turn on the front defroster, and leave the vehicle until the SOC value is below 40%.

      HINT:

      If the SOC is substantially below 40%, the HV battery may become fully discharged. Therefore, do not allow the SOC to reach substantially below 40%.

    8. Move the shift lever to the P position and turn the power switch off.
    9. Disconnect the negative terminal from the auxiliary battery and leave it for 1 minute or more.

    15. Depress the accelerator pedal with your right foot while firmly depressing the brake pedal with your left foot, and maintain an engine load value of 45% or more (accelerator pedal depressed 60 to 70%) for approximately 30 seconds.
      NOTE: Do not perform this step for 40 seconds or more.
    16. Shift the shift lever to the P position. Turn the power switch off and then wait for 5 seconds before turning the power switch on (READY).
    17. Select the following menu items: Powertrain / Engine and ECT / Data List / ISC Learning.
    18. Check that the air conditioner is off. Lightly depress the accelerator pedal and release it when the engine starts.

      HINT:

      • If "ISC LEARNING" is not completed within 1 minute, repeat steps (o) through (r).
      • The engine will usually stop when "ISC LEARNING" is completed. However, the engine will not stop even when "ISC LEARNING" is completed in such cases when the charge level of the auxiliary battery is decreased.
  8. DESCRIPTION OF CODE REGISTRATION (Tire Pressure Warning System) 

    It is necessary to register the transmitter IDs in the tire pressure warning ECU when replacing a tire pressure warning valve and transmitter and/or tire pressure warning ECU.

    Prepare all transmitter ID data before starting registration.

    1. Before registration
      1. When replacing the tire pressure warning ECU:
        • Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
        • If reading stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters (See TIRE PRESSURE WARNING SYSTEM ).
      2. When replacing a tire pressure warning valve and transmitter:
        • Take a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
      Fig 3: Identifying Transmitter ID
      G05001340Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      NOTE: The transmitter ID is written on the tire pressure warning valve and transmitter. It will be unable to be read after installing the tire onto the wheel. Therefore, take a note of the transmitter ID before installing the tire onto the wheel.
  9. REGISTER TRANSMITTER ID (USING TECHSTREAM) (Tire Pressure Warning System) 
    1. Set the air pressure of all tires to the specified value (See TIRE PRESSURE WARNING SYSTEM ).

        HINT:

        Refer to the Techstream operator's manual for further details.

      6. Confirm that the initial sensor reading is within the specified range.

        Standard: 

        -3.2 to 3.2 kg (-7 to 7 lb) 

      7. Place a 30 kg (66.14 lb) weight (eg. a 30 kg (66.14 lb) of lead mass) onto the front passenger seat.
      8. Confirm that the sensitivity is within the specified range.

        Standard: 

        27 to 33 kg (59.52 to 72.75 lb) 

        HINT:

        • When performing the sensitivity check, use a solid metal weight (the check result may not appear properly if a liquid weight made from liquid is used).
        • If the sensitivity deviates from the specified range, retighten the bolts of the front passenger seat without deforming the seat rail. After performing this procedure, if the sensitivity is not within the specified range, replace the front seat assembly RH.
  16. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ON DRIVER SIDE)) (Power Window Control System) 
    NOTE:

    • Initialization should be made when the vehicle is stationary.
    • Be sure to initialize the door glass position memory (pulse sensor) after replacing the driver side power window regulator motor assembly. Without the initialization, the driver door auto up-and-down function, jam protection function and key-off operation will not work.
    • Be sure not to tap or give any shock or force to the door glasses during the initialization procedure as the vehicle is learning the door glasses' sliding resistance during initialization.
    • After replacing the driver side power window regulator, door glass, or glass adhesive dams, be sure to initialize the door glass position memory (pulse sensor). Otherwise, the jam protection function may work when unnecessary.

    If the initialization procedure cannot be completed normally, there may be a malfunction in the Local Interconnect Network (LIN) communication. Check the body multiplex (LIN) communication system.

    1. Inspection procedure
      Fig 14: Initialization Inspection Procedure Chart
      G05413004Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      • *1: Even if the door glass has been fully opened before procedure No. 3, it is necessary to press the power window switch down for at least 1 second.
      • *2: As soon as the switch is pulled completely up (automatic closing), the master switch indicator starts to blink.
      • *3: If the master switch indicator does not come on after procedure No. 4, restart from procedure No. 3.
      • *4: Allow the automatic operation to continue without stopping until the door glass is fully closed.

        Check the body multiplex LIN system (See SYSTEM DESCRIPTION ).

  17. TO RETURN THE SYSTEM TO THE PRE-INITIALIZED CONDITION (Power Window Control System) 
    NOTE: After replacing or reinstalling the driver side power window regulator, door glass, or door glass adhesive dams, be sure to initialize the door glass position memory (pulse sensor). Otherwise, the jam protection function may work when unnecessary.

      • *3: After completing the whole initialization process, make sure that the door glass fully closes with the automatic closing operation.
      • If the initialization procedure cannot be completed normally, there may be a malfunction in the Local Interconnect Network (LIN) communication. Check the body multiplex (LIN, Local Interconnect Network) communication system (See SYSTEM DESCRIPTION ).
