Engine Immobiliser System: Registration

  1. DESCRIPTION OF CODE REGISTRATION 

    HINT:

    • The engine immobiliser function's ID code is the same as recognition codes for the smart access system with push-button start, the wireless transmitter. Registering an ID code enables the smart access with push-button start, the wireless door lock control function and the engine immobiliser function to be operated.
    • Code registration is needed when the certification ECU, immobiliser code ECU, steering lock ECU or key is replaced with a new one.
    • This vehicle does not have a key slot. Therefore, hold the key close 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 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 immobiliser code ECU is also required.
      • A maximum of 7 keys can be registered.
