Section 249 (Smart Key System - Diagnosis): Registration

NT:

• Smart key code is the same as recognition codes for the wireless transmitter. Registering a smart key code enables both the smart key system and the wireless door lock control system to be operated.
• Code registration is needed when the theft warning ECU (theft deterrent ECU) or smart key is replaced with a new one.
• There are 2 types of keys: a master key that has a trunk open switch and a sub-key that does not have a trunk open switch.
• The smart key system functions can be operated only by a master key.

1. Select the operation mode from the following:
   • New registration mode (When theft warning ECU is replaced):

     The new registration mode is used when the theft warning ECU is replaced with a new ECU. In this mode, be sure to register a master key code first. Otherwise, you cannot proceed to the add mode for registering other keys. If a sub key code is registered first, pressing one of the transmitter's switches (master key (transmitter) switch operation in the add mode^* ) to try to make an additional key registration erases the registered sub key code.

     ^* Refer to the registration flowchart on the next page.

   • Add mode:

     The add mode is used when a new key is added.

   • Erase mode:

     The erase mode is used to erase all the key codes except for the code for the master key that is used during erasure mode. Use this mode in such a case where the key is lost.

   • Confirmation mode:

     The confirmation mode is used to confirm the number of key codes (master key and sub key) that are registered in the theft warning ECU. During key code registration mode (new registration mode or add mode), you can confirm the number of registered key codes on the tester's screen, "SMART (KEY) CODE REGISTRATION".

2. Perform the code registration and the code erasure according to the flowcharts (see step 2 and 3).

   HINT:

   • Up to 5 master keys and 3 sub-keys can be registered in the theft warning ECU.
3. Register a new key number or change the key number according tot he flowcharts (see step 4 and 5). When the theft warning ECU is replaced or all the key cylinders are replaced, be sure to register a new key number or change the key number in the theft warning ECU.

HINT:

A key number is a 5 digit code stamped on the key number plate.
