Engine Immobilizer System: Registration

  1. DESCRIPTION OF CODE REGISTRATION 

    HINT:

    • The engine immobilizer function 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 system with push-button start, wireless door lock control function and engine immobilizer function to be operated.
    • Code registration is needed when the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), steering lock ECU, ECM 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 engine switch to register the key, as shown in the illustration.
  2. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES 
    1. If a malfunctioning ECU is discovered through troubleshooting of the smart access system with push-button start, use the ECU replacement and key registration procedures in the table below.

      HINT:

      • The following procedures require the use of the Techstream:
        • New key ID registration
        • Additional key ID registration
        • Key ID erasure
        • ECU code registration
          Fig 1: Identifying Engine Switch

      • When simply adding a new key (without losing or replacing any existing keys), refer to  c"Additional key ID registration" under Key Registration Procedures.
      • If all of the registered keys are not available, replacement of the ID code box (immobilizer code ECU), certification ECU (smart key ECU assembly) and steering lock ECU is also required.
      • A maximum of 7 keys can be registered.

      PROCEDURE CHART

      Process Procedure
      1 Start of registration
      1. Connect the Techstream to DLC3
      2. Turn the engine switch on (IG)

        HINT

        The engine switch cannot be turned on (IG) more than 10 times To continue the key registration procedure with the engine switch off, after connecting the Techstream, turn the Techstream on while turning the driver side door courtesy light switch on and off repeatedly at intervals of 1 5 seconds

      3. Turn the Techstream on
      4. Enter the following menus. Smart Access / Utility / Key Code Registration
      2 Confirmation of ECU code Perform operation according to prompts on the Techstream screen
      HINT
      Mode is automatically selected by the Techstream (new registration mode or add mode)
      3 Verification of unregistered key*
      1. Touch logo of unregistered key to engine 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 Perform operation according to prompts on the Techstream screen
