Engine Immobilizer System: Registration

  1. DESCRIPTION OF CODE REGISTRATION 

    HINT:

    • ID codes are the same as recognition codes for the wireless transmitter and the engine immobilizer function. Registering an ID code enables the smart access system with push-button start, the wireless door lock control function and the engine immobilizer function to be operated.
    • Code registration is needed when the certification ECU, ID code box, steering lock ECU or key is replaced with a new one.
    1. PROCEDURE "1"

      The vehicle with the smart access system with push-button start system does not have a key slot. Therefore, hold the key close to the engine switch to register the key, as shown in Fig 1 .

  2. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES 
    1. The following table shows ECU replacement and key registration procedures in case the malfunctioning ECU has been specified after troubleshooting the smart access system with push-button start.

      HINT:

      • The following procedures indicated in DIAGNOSIS PROCEDURE TABLE  require the use of the intelligent tester: New key ID registration Additional key ID registration Key ID erasure ECU code registration
      • If all of the registered keys are not available, replacement of the ID code box is also required.
      • A maximum of 7 keys can be registered.

  3. KEY REGISTRATION PROCEDURES 
    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)

      DIAGNOSIS PROCEDURE TABLE

      Process Procedure
      Start of registration
      1. Connect intelligent tester (with CAN VIM) to DLC3
      2. Turn engine switch on (IG)
      3. Select "SMART ACCESS / ID UTILITY / SMART CODE REG" from tester menu
      HINT:The engine 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 second intervals or less to continue key registration procedure
      Confirmation of ECU code Perform operation according to prompts on tester screen
      HINT:
      The mode is automatically selected by tester, new registration mode or add more
      Verification of unregistered key (1) Hold unregistered key close to engine switch (For details, refer to PROCEDURE 1)
      Confirm that wireless door lock buzzer sounds. Place unregistered key on front passenger side seat
      Confirm that wireless door lock buzzer sounds
