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 ID codes are the same as recognition codes for the wireless transmitter and the engine immobiliser function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobiliser function to be operated.
* Code registration is necessary when the certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU), steering lock ECU, or key is replaced with a new one.
(a) Vehicles with the smart key system do not have a key slot. Therefore, hold the key close to the engine switch to register the key, as shown in the illustration.

2. PART REPLACEMENT AND KEY REGISTRATION

(a) The following table shows ECU replacement and key registration procedures for cases in which a malfunctioning ECU has been identified through the troubleshooting of the smart key system.

HINT
* The following procedures can be performed:
* New key ID registration
* Additional key ID registration
* Key ID erasure
* All key ID erasure
* ECU code registration
* If the customer has not brought all the registered keys, replacement of the ID code box (immobiliser code ECU) is also required.
* A maximum of 4 keys can be registered.

3. KEY REGISTRATION

(a) PROCEDURE "A"

New key ID registration (when replacing the certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU), or when replacing the certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU) and steering lock ECU)

* *1: Repeat this process for each key which is to be registered for 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 procedures again from process 1. Make sure that only 1 key is in the cabin during the registration procedures. If 2 or more keys are in the cabin simultaneously, electric waves will interfere with each other, preventing normal registration.

(b) PROCEDURE "B"

New key ID registration (when replacing the certification ECU (smart key ECU assembly))

* *1: Repeat this process for each key registered for 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 procedures again from process 1. If the key confirmation procedure for a key is performed, 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 for 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 procedures again from 1. Make sure that only 1 key is in the cabin during the registration procedures. If 2 or more keys are in the cabin simultaneously, electric waves will interfere with each other, preventing normal registration.

(c) PROCEDURE "C"

Additional key ID registration

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

* *2: Repeat this process for each key which is to be registered for 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 procedures again from 1. Make sure that only 1 key is in the cabin during the registration procedures. If 2 or more keys are in the cabin simultaneously, electric waves will interfere with each other, preventing normal registration.

(d) PROCEDURE "D"

Key ID erasure

HINT
Erase all registered key codes except one.

(f) PROCEDURE "F"

ECU code registration

* *1: Perform this process for one of the keys registered for the vehicle. Finish the procedure within 30 seconds. If the procedure has not been finished within the specified time, perform the erasure procedures again from process 1.

(g) PROCEDURE "G"

ECU communication ID registration

NOTICE:
* The ECU communication ID should be registered when the ID code box (immobiliser code ECU) is replaced in order to match these ECU communication IDs.
* The engine cannot be started unless the ECU communication IDs match.
* After the registration, pressing the engine switch may not start the engine on the first try. If so, press the engine switch again.
* Clear DTC B2799 (code for ECM's immobiliser communication error) by either of the following:
* - Use the Techstream.
* - Disconnect the battery for 30 seconds.
(1) Using SST, connect terminals TC and CG of the DLC3.

SST : 09843-18040

(2) Turn the engine switch on (IG) and leave it as is for 30 minutes.

HINT
Do not start the engine.

(3) Turn the engine switch off and disconnect terminals TC and CG.

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

(h) PROCEDURE "H"

ECU communication ID registration

NOTICE:
The ECU communication ID should be registered when the ECM is replaced in order to match the ECU communication IDs.
