REGISTRATION

PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

HINT:

The engine immobiliser function ID code is the same as the recognition code for the smart key system and wireless transmitter. Registering an ID code enables the smart key system, wireless door lock control function and engine immobiliser 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.

4. KEY REGISTRATION PROCEDURES

(a) PROCEDURE "A"

New key ID registration (when replacing certification ECU and ID code box, or certification ECU, ID code box and steering lock ECU), or when performing all keys ID erasure (key code reset):

Process	Procedure
1. Start of registration	Connect the Techstream to DLC3 Turn engine switch on (IG) HINT: Engine switch cannot be turned on (IG) more than 10 times. To continue key registration procedure with engine switch off, after connecting the Techstream, turn the Techstream on while turning driver side door courtesy light switch on and off repeatedly at intervals of 1.5 seconds. Turn the Techstream on Enter the following menus: Smart Key / Utility / Key Code Registration
2. Confirmation of ECU code	Perform operation according to prompts on the Techstream screen HINT: Mode is automatically selected by the Techstream (new registration mode or add mode)
3. Verification of unregistered key*	Touch logo of unregistered key to engine switch Confirm that wireless door lock buzzer sounds once (short beep) Place unregistered key on front passenger side seat Confirm that wireless door lock buzzer sounds once (short beep)
4. Registration of ID code	Perform operation according to prompts on the Techstream screen
5. End of registration	Finish new key ID code registration

HINT:

*: Repeat this process for each key which is to be registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys is not finished within the specified time, perform the registration from process 1 again. Make sure that only 1 key is in the cabin during registration. If 2 or more keys are in the cabin simultaneously, the electric waves will interfere with each other, preventing normal registration.

ECU communication ID registration:

NOTICE:

The ECU communication ID should be registered when the ID code box is replaced in order for the ECU communication ID to match.
The engine cannot be started unless the ECU communication ID is registered.
After registration, pressing the engine switch may not start the engine on the first try. If so, press the engine switch again.
After the engine is started, clear DTC B2799 (code for ECM immobiliser communication error) using either of the following methods:
- Use the Techstream.

- Disconnect the cable from the negative (-) battery terminal for 30 seconds.
