Engine Immobilizer System





ENGINE IMMOBILIZER: ENGINE IMMOBILIZER SYSTEM: REGISTRATION

1. DESCRIPTION OF CODE REGISTRATION

HINT
* The engine immobilizer function's ID code is the same as recognition codes for the smart access system with push-button start and the wireless transmitter. Registering an ID code enables the smart access with push-button start, the wireless door lock control function and the engine immobilizer function to be operated.
* The key (for card type) can be registered using the same procedure as the key (for standard type).
* Code registration is needed when the certification ECU, ID code box, steering lock ECU, hybrid vehicle control ECU or key is replaced with a new one.





* This vehicle does not have a key slot. Therefore, hold the key close to the power 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 8 keys can be registered.






3. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES

(a) If a malfunctioning ECU is discovered through troubleshooting of the smart access system with push-button start, 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 8 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 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 registration procedures from process 1 again. Make sure that only 1 key is in the cabin during 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 certification ECU)





HINT
* *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 registration procedures from process 1 again. If performing the key confirmation procedure for a key, the security indicator 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 has not been finished within the specified time, perform registration procedures from 1 again. Make sure that only 1 key is in the cabin during 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





HINT
* *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 registration procedures from process 1 again.
* *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 has not been finished within the specified time, perform registration procedures from 1 again. Make sure that only 1 key is in the cabin during 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 (Erase all registered key codes except one)





HINT
*: 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 erasure procedures from process 1 again.

(e) PROCEDURE "E"

NOTICE:
Do not erase all registered key codes except one key (for card type) while the smart access system with push-button start system key cancel is activated. By doing so, the smart access system with push-button start system cannot be returned to its original condition using the electrical key cancel operation Smart Access System With Push-Button Start. In addition, the entry unlock switching function Smart Access System With Push-Button Start cannot be used. However, erasing all registered key codes except one key (for card type) will not cause problems if registering additional keys (for standard type).

(e) All keys ID erasure





(f) PROCEDURE "F"

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 registration procedures from process 1 again.

(g) PROCEDURE "H"

ECU communication ID registration

NOTICE:
* The ECU communication ID should be registered when the ID code box is replaced in order to match the ECU communication ID.
* The hybrid control system cannot be started unless ECU communication ID is registered.
* After the registration, pressing the power switch may not start the hybrid control system on the first try. If so, press the power switch again.
* After the hybrid control system is started, erase DTC B2799-542,790 (code for hybrid vehicle control ECU's immobilizer communication error) using either of the following methods:
* - Use the Techstream.
* - Disconnect the battery for 30 seconds.
