Engine Immobiliser System: Registration: Registration

WARNING: This page is about a different variant/trim than selected.
  1. DESCRIPTION OF CODE REGISTRATION 

    HINT: 

    • The ID codes are the same as recognition codes for the wireless transmitter and engine immobiliser function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobiliser function to be operated.
    • Code registration is necessary when the certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU), transmission control ECU assembly or key is replaced with a new one.
    1. When registering a key, bring the key close to the power switch 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.
    Situation 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"
    • Replacing a key
    • Making a lost key unable
    HINT: After key ID erasure, any remaining keys that are not registered at this time cannot be used. Therefore, after key ID erasure, register all remaining keys.    		 Customer must bring at least 1 key 1. Using remaining keys, clear all registered keys except one (key ID erasure) PROCEDURE "D"
    2. Register additional keys as necessary (additional key ID registration) PROCEDURE "C"
    All keys are lost - 1. Reset all keys (all key ID erasure (key code reset)) PROCEDURE "E"
    2. Register all keys (new key ID registration) PROCEDURE "A"
  3. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES 
    1. The following table shows ECU replacement and key registration procedures for cases in which a malfunctioning ECU has been identified through the troubleshooting of the smart key system.

      HINT: 

      • The following procedures can be performed:
        • New key ID registration
        • Additional key ID registration
        • Key ID erasure
        • All key ID erasure
        • ECU code registration
      • If the customer has not brought all the registered keys, replacement of the transmission control ECU assembly or ID code box (immobiliser code ECU) is also required.
      • A maximum of 7 keys can be registered.

      Process Procedure
      1. Start of registration
      1. Connect the Techstream to DLC3
      2. Turn the power switch on (IG)
      3. Enter the following menus: Body Electrical / Smart Key / Utility / Smart Code Registration
      HINT: The power switch cannot be turned on (IG) more than 10 times. After connecting the Techstream, turn the Techstream on while turning the driver door courtesy light switch on and off repeatedly at 1.5-second intervals or less to continue key registration procedure.
      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
      1. Hold the unregistered key close to the power switch (for details, refer to REGISTRATION  )
      2. Confirm that the wireless door lock buzzer sounds once (short beep)
      3. Place the unregistered key on the driver seat
      4. Confirm that the wireless door lock buzzer sounds once (short beep)
