Engine Immobiliser System (W/ Smart Key System)

THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM (w/ Smart Key System): REGISTRATION

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.

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
* A maximum of 7 keys can be registered.

3. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES

(a) 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
* - Additional key ID registration
* - Key ID erasure
* - ECU code registration
* A maximum of 7 keys can be registered.

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):

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.

(b) PROCEDURE "B"

New key ID registration (when replacing certification ECU):

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 is not 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 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.
(c) PROCEDURE "C"

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 is not 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 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.
(d) PROCEDURE "D"

Key ID erasure (clear all registered key codes except one):

(f) PROCEDURE "F"

ECU code registration:

HINT
*: Perform this process for one of the keys registered to the vehicle. Finish the procedure within 30 seconds. If the procedure is not finished within the specified time, perform the registration from process 1 again.

(g) PROCEDURE "G"

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.
(1) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

SST : 09843-18040

(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).

(4) Check that the engine starts and stays on for more than 3 seconds.
