ENGINE IMMOBILIZER: ENGINE IMMOBILIZER SYSTEM: REGISTRATION

REGISTRATION

1. DESCRIPTION OF CODE REGISTRATION
HINT:
- The engine immobiliser function's ID code is the same as the recognition code for the smart access system with push-button start and wireless transmitter. Registering an ID code enables the smart access with push-button start, 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, hybrid vehicle control ECU 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 power switch to register the key, as shown in the illustration.

2. 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 intelligent tester or Techstream:
- New key ID registration
- When simply adding a new key (without losing or replacing any existing keys), refer to "3. KEY REGISTRATION PROCEDURES (c) Additional key ID registration".
- If all of the registered keys are not available, replacement of the ID code box, certification ECU and steering lock ECU is also required.
- A maximum of 7 keys can be registered.

3. KEY REGISTRATION PROCEDURES
(a) New key ID registration (when replacing certification ECU and ID code box, or certification ECU, ID code box and steering lock ECU)

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) 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 process 1 again. If 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 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.

(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 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.

(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) All keys ID erasure

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) 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 B2799-790 (code for hybrid vehicle control ECU's immobiliser communication error) using either of the following methods:
- Use the intelligent tester or Techstream.
- Disconnect the battery for 30 seconds.

(1) Using SST, connect terminal 13 (TC) and 4 (CG) of the DLC3.
SST: 09843-18040
(2) Turn the power switch ON (IG) (do not start the hybrid control system) and leave it as is for 30 minutes.
(3) Turn the power switch OFF and disconnect terminals 13 (TC) and 4 (CG).
(4) Check that the hybrid control system starts for more than 3 seconds.
(h) ECU communication ID reregistration
NOTE: The ECU communication ID should be registered when the hybrid vehicle control ECU is replaced in order to match the ECU communication ID.
