Engine Immobilizer System

  1. DESCRIPTION OF CODE REGISTRATION

    HINT: 

    • The engine immobilizer function's ID code is the same as the recognition code for the smart access system with push-button start and wireless transmitter. Registering an ID code enables the smart access with push-button start, wireless door lock control function and engine immobilizer function to be operated.
    • Code registration is needed when the certification ECU, ID code box, steering lock ECU, hybrid vehicle control ECU or key is replaced with a new one.

    • This vehicle does not have a key slot. Therefore, touch the logo of the key to the power switch to register the key, as shown in the illustration.
  2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

    HINT: 

    • The following procedures require the use of the Techstream:
      • - New key ID registration
      • - Additional key ID registration
      • - Key ID erasure
    • A maximum of 7 keys can be registered.
        Registration Procedure Condition Procedure Refer to
      Registering an additional key Customer must bring at least 1 key 1. Register additional keys as necessary (additional key ID registration)  PROCEDURE "C"

    1. PROCEDURE "A"

      New key ID registration (when replacing certification ECU and ID code box, or certification ECU , ID code box and steering lock ECU), or when performing all keys ID erasure (key code reset)

      Process Procedure
      1. Start of registration
      1. Connect Techstream to DLC3
      2. Turn power switch ON (IG)
      3. Select "Smart Access/Utility/Key Code Registration" from tester menu
      HINT: Power switch cannot be turned ON (IG) more than 10 times. After connecting tester, turn tester on while turning driver side door courtesy light switch on and off repeatedly at 1.5 seconds intervals or less to continue key registration procedure.
      2. Confirmation of ECU code
      • Perform operation according to prompts on tester screen
      HINT: Mode is automatically selected by tester (new registration mode or add mode)
      3. Verification of unregistered key*
      1. Touch logo of unregistered key to power switch
      2. Confirm that wireless door lock buzzer sounds once (short beep)
      3. Place unregistered key on front passenger side seat
      4. Confirm that wireless door lock buzzer sounds once (short beep)
      4. Registration of ID code

If the procedure for any of the keys has not been finished within the specified time, perform registration procedures from process 1 again. Make sure that only 1 key is in the cabin during registration procedures. If 2 or more keys are in the cabin simultaneously, electric waves will interfere with each other, preventing normal registration.
