Engine Immobilizer System: Registration

  1. DESCRIPTION OF CODE REGISTRATION 

    HINT:

    • The engine immobilizer function's ID code is the same as recognition codes for the smart access system with push-button start and the wireless transmitter. Registering an ID code enables the smart access 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, 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 NEW KEY ID REGISTRATION PROCEDURES .

      HINT:
      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.
      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 engine switch
      2. Confirm that wireless door lock buzzer sounds once (short beep)
      3. Place unregistered key on front passenger side seat
