IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND CLEARING [KEYLESS ENTRY SYSTEM]

Foreword

- When performing the following procedures, the immobilizer resetting procedure using the M-MDS must also always be performed: "instrument cluster replacement", "PCM replacement", "instrument cluster and PCM joint replacement", "Key ID number clearing". The engine will not start unless all work is performed using the M-MDS.
- There are two methods for registering an additional key: Using the M-MDS and using two keys that are able to start the engine.
- When replacing any of the immobilizer system component parts, adding/erasing keys or performing other functions, refer to the following table and perform the applicable procedure (No.1 to 5).

CAUTION:
- If any of the following items are touching or near the key head, signal communication between the key and vehicle is negatively affected, resulting in the engine not starting or the key registration failure. Do not perform the procedure if any of the following items are touching or near the key head.

- Any metallic object
- Spare keys or keys for other vehicles equipped with an immobilizer system
- Any electronic device, or any credit or other cards with magnetic strips

NOTE:
- Within the following procedures, the term a "valid key" means a "key that can start the engine".
- After adding/registering keys, clearing ID numbers or replacing any component part of the immobilizer system, verify that all keys can start the engine within 5 s.
- When verifying that the keys can start the engine, wait at least 5 s or more between inserting them.
- If the engine cannot be started using a registered key, repeat the procedure from the beginning.
- Do not start the engine until the key registration procedure for all the necessary keys is completed. If the engine is started during the registration procedure, registration is stopped at that point. Repeat the procedure starting from the beginning if the engine is started before completion.
- Two or more key ID numbers must be registered for the engine to start.
- A maximum of eight key ID numbers can be registered for one vehicle. The M-MDS can be used to verify the number of key ID numbers registered to a single vehicle.
- Do not select screen menus of the M-MDS that are not indicated within the procedures.

No.1 Additional Key Registration Procedure (Using Two Valid Keys)

Conditions
- Customer has two or more valid keys.

NOTE:
- A maximum of eight keys can be registered for any one vehicle. If key registration is not successful and DTC 15 appears even though the procedure was performed properly, use the PID/data monitor function of the M-MDS and verify the number of keys that have been registered.
- If eight keys have already been registered, and it is necessary to register other keys, the previously registered key ID numbers must first be cleared. To clear the key ID numbers, refer to "No.3 Key Replacement Procedure (Clearing Previously Registered Key ID Numbers , Key Re-registration)".

Procedure

1. Have one key (key 3) ready for registration.

2. Using key 1, turn the ignition switch to the ON position.

3. Verify that the security light illuminates for approx. 3 s and then goes out.

4. Using key 1, turn the ignition switch to the LOCK position within approx. 4 s after the security light goes out.

5. Remove key 1

6. Repeat Steps 2-5 using key 2.

7. Repeat Steps 2-5 using key 3.

8. If additional keys need to be registered, repeat Steps 1-7 in the same manner as key 3.

Procedure

1. Have one key (key 1) ready for registration.

2. Using key 1, turn the ignition switch to the ON position.
