INITIALIZATION - Continued

12. REGISTRATION RELATED TO GARAGE DOOR OPENER SYSTEM
(a) REGISTER TRANSMITTER CODE
HINT:
- The vehicle garage door opener records transmitter codes for systems such as garage doors, gates, entry gates, door locks, home lighting systems, security systems or other transmitter code based systems.
- The garage door opener is built into the map light assembly. If replacing the map light assembly transmitter, codes for any systems previously registered in the garage door opener must be reregistered.
(1) Register systems in the garage door opener registration mode.
CAUTION: Do not perform transmitter code registration for a system if people or objects are near the system. When registering transmitter codes for a system, injury or damage can occur because the system may open, close, unlock or otherwise operate.
NOTICE:
- Before transmitter code registration, confirm that all the electrical systems (headlight, blower motor, rear defogger, etc.) are turned off and that no key is in the vehicle.
- The garage door opener cannot be used with systems that: 1) were manufactured before April 1, 1982, or 2) do not meet Federal Standards (for example, garage doors without a jam protection function).
HINT:
- 3 transmitter codes can be registered with the garage door opener, one transmitter code for each of the 3 garage door opener switches.
- Disconnecting the battery will not clear the transmitter codes registered with the garage door opener.

1. Select a garage door opener switch for transmitter code registration.
2. Press and hold the selected switch. The garage door opener will enter registration mode after a brief pause.

HINT: After entering registration mode, the LED flashes at a frequency of 1 Hz.

3. After the garage door opener has entered registration mode, continue holding the selected garage door opener switch and bring the original transmitter of the system to be registered within 1 inch of the garage door opener switches. Then, without releasing the selected garage door opener switch, press and hold the original transmitter switch.

4. If the transmitter code registration was successful, the LED of the garage door opener flashes at a frequency of 5.6 Hz, and the registration completes. If no malfunction occurs, release both the garage door opener switch and the original transmitter switch.

(2) Overwrite previously registered systems in the garage door opener registration mode.
1. Select a garage door opener switch that will be overwritten with a new transmitter code.
2. Press and hold the selected switch. After approximately 20 seconds, the garage door opener will enter registration mode.

HINT: Before entering registration mode, the LED is on. After entering registration mode, the LED flashes at a frequency of 1 Hz.

3. After the garage door opener has entered registration mode, continue holding the selected garage door opener switch and bring the original transmitter of the system to be registered within 1 inch of the garage door opener switches. Then, without releasing the selected garage door opener switch, press and hold the original transmitter switch.

4. If the transmitter code registration was successful, the LED of the garage door opener flashes at a frequency of 5.6 Hz, and the overwriting completes. If no malfunction occurs, release both the garage door opener switch and the original transmitter switch.
HINT:
- If transmitter code registration fails: 1) the original transmitter battery may be low or need to be replaced, or 2) the system you are trying to register may not be compatible with the garage door opener.
- The signals of some transmitters stop after 1 to 2 seconds. For these types of transmitters: 1) press and hold one of the garage door opener switches, and 2) press and release (cycle) the transmitter switch every 2 seconds. Check if the transmitter code was successfully registered.
- After entering the garage door opener registration mode, transmitter code registration must be completed within 55 seconds. If 55 seconds elapse, the garage door opener will enter low power mode (refer to the "low power mode" below).

(3) Clear transmitter codes in the garage door opener clear mode.
HINT: All 3 registered transmitter codes will be cleared. No option exists for only erasing one transmitter code.

1. Press and hold the left and right switches at both ends of the garage door opener for 10 seconds. The LED will flash at a frequency of 5.6 Hz, and clearing is completed. Releasing the switches will end clear mode.

HINT:
- If the switches are released within 10 seconds after the transmitter codes have been cleared, the garage door opener will enter registration mode.
- If the switches are held for 10 seconds or more after the transmitter codes have been cleared, default codes will be set to the switches of the garage door opener. Using these default codes, operation of the garage door opener can be checked using a tester.

(4) Low power mode:
1. If the garage door opener switch is held for 75 seconds or more, the garage door opener will enter low power mode to economize on power consumption. When the garage door opener has entered low power mode, the LED turns off.

(b) DESCRIPTION OF CODE REGISTRATION
HINT:
- The engine immobilizer 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 (smart key ECU assembly), ID code box (immobiliser code ECU), 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.

13. REGISTRATION RELATED TO ENTRY AND START
(a) PART REPLACEMENT AND KEY REGISTRATION PROCEDURES
(1) If a malfunctioning ECU is discovered through troubleshooting of the smart key system, use the ECU replacement and key registration procedures in the table below.
HINT:
- The following procedures require the use of the Techstream:
- New key ID registration
- When simply adding a new key (without losing or replacing any existing keys), refer to "Additional key ID registration" under Key Registration Procedures.
- If all of the registered keys are not available, replacement of the ID code box (immobiliser code ECU), certification ECU (smart key ECU assembly) and steering lock ECU is also required.
- A maximum of 7 keys can be registered.

(b) KEY REGISTRATION PROCEDURES
(1) New key ID registration (when replacing certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU), or certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU) and steering lock ECU):

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 has not been 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.
(2) New key ID registration (when replacing certification ECU (smart key ECU assembly)):

HINT:
- *1: Repeat this process for each key registered to the vehicle. Finish the procedure for each key within 30 seconds. If the procedure for any of the keys has not been finished within the specified time, perform the registration from process 1 again. When performing the key confirmation procedure for a key, the security indicator light comes on and remains on until all the keys are confirmed.
- *2: 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 has not been 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.
(3) Additional key ID registration:

HINT:
- *1: Perform this process for one of the keys registered to the vehicle. Finish the procedure within 30 seconds. If the procedure has not been finished within the specified time, perform the registration from process 1 again.
- *2: 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 has not been 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.
(4) Key ID erasure (clear all registered key codes except one):

HINT: *: Perform this process for one of the keys registered to the vehicle. Finish the procedure within 30 seconds. If the procedure has not been finished within the specified time, perform the registration from process 1 again.
(7) ECU communication ID registration:
NOTICE:
- The ECU communication ID should be registered when the ID code box (immobiliser code ECU), steering lock ECU or ECM is replaced in order to match the ECU communication ID.
- The engine cannot be started unless ECU communication ID is registered.
- After the 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.

SST: 09843-18040
1. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
2. Turn the engine switch on (IG) (do not start the engine) and leave it as is for 30 minutes.
3. Turn the engine switch off and disconnect terminals 13 (TC) and 4 (CG).
