REGISTRATION PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

HINT:

  • The ID codes are the same as recognition codes for the wireless transmitter and the 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), steering lock ECU (steering lock actuator assembly), or key is replaced with a new one.

(a) Vehicles with the smart key system do not have a key slot. Therefore, hold the key close to the engine switch to register the key, 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
    • -All key ID erasure
  • A maximum of 7 keys can be registered.
