Registration [08/2019 - 08/2021]: Procedure

HINT: 

• Registering an ID code enables the smart key function, wireless door lock control function and immobilizer function to be operated.
• Code registration is needed when the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), main body ECU (multiplex network body ECU), steering lock ECU (steering lock actuator assembly) or electrical key transmitter sub-assembly is replaced with a new one.
• This vehicle does not have a key slot. Therefore, while facing the logo side of the electrical key transmitter sub-assembly towards the engine switch, hold the transmitter near the engine switch as shown in the illustration to register the electrical key transmitter sub-assembly.

HINT: 

• The following procedures require the use of the Techstream:
  1. - New key ID registration
  1. - Additional key ID registration
  1. - Key ID erasure
  1. - All Key ID erasure
• A maximum of 7 electrical key transmitter sub-assemblies can be registered (this includes any electrical key transmitter sub-assemblies registered when the vehicle was purchased).
• In the chart below, the numbers in the "Procedure" column (1, 2, 3, etc.) indicate step numbers. Perform the steps in numerical order.

1. If a malfunctioning ECU is discovered through troubleshooting of the smart key, use the ECU replacement and electrical key transmitter sub-assembly registration procedures in the table below.
   NOTE:

   Do not use a main body ECU (multiplex network body ECU) and DCM (telematics transceiver) that has been registered to another vehicle.

   HINT: 

   • The following procedures require the use of the Techstream:
     1. - New key ID registration
     1. - Additional key ID registration
     1. - Key ID erasure
     1. - ECU code registration
   • A maximum of 7 electrical key transmitter sub-assemblies can be registered (this includes any electrical key transmitter sub-assemblies registered when the vehicle was purchased).
   • Immediately after replacing the certification ECU (smart key ECU assembly), the Techstream item "A number of registered codes" should change to "0". If this item does not change to "0", the certification ECU (smart key ECU assembly) may be registered to another vehicle. A certification ECU (smart key ECU assembly) which is registered to another vehicle cannot be used.

Turn Techstream on Enter following menus: Body Electrical / Smart Key / Utility / Smart Code Registration
   2. Confirmation of ECU code	Perform operation according to prompts on Techstream screen HINT: Mode is automatically selected by Techstream (new registration mode or add mode)
   3. Verification of unregistered electrical key transmitter sub-assembly*	While facing logo side of unregistered transmitter toward engine switch, hold transmitter near engine switch. Confirm that wireless door lock buzzer sounds twice (short beep) Bring electrical key transmitter sub-assembly for which operations have been completed outside vehicle. Then bring another new electrical key transmitter sub-assembly for which operations are to be performed into vehicle.
   4. Registration of ID code	Perform operation according to prompts on Techstream screen
