Before Service Preparation And Precautions

- When performing the following procedures, the immobilizer resetting procedure using the M-MDS must also always be performed: "Keyless control module replacement", "PCM replacement", "Steering lock unit replacement", and "Key ID number clearing". The engine will not start unless all work is performed using the M-MDS.
- A card key that can start the engine is necessary for the key programming. If there is no card key that can start the engine, perform the key programming after the card key programming. Card Key ID Code Registration
- There are two ways to add supplemental key: Using the M-MDS or using two keys that can start the engine to program.
- When replacing any of the immobilizer system component parts, adding/clearing keys, or performing other functions, refer to the following table and perform the applicable procedure (No.1 to 8).
- Verify that the room fuse is equipped.










CAUTION:
- The following conditions may cause poor signal communication between the key and vehicle, resulting in the engine not starting or a key registration error. Do not perform any work under the following conditions:

- Placing the following items close to the key grip or contacting it.

- Spare keys
- Keys for other vehicles equipped with an immobilizer system
- Any metallic object
- Any electronic device, or any credit or other card with magnetic strips
- Do not place the following devices in the vehicle while programming, otherwise programming cannot be performed:

- Card key
- M-MDS
- Personal computer
- Devices that can send/receive the radio waves

NOTE:
- The "valid key" used in this information indicates the key that can start the engine.
- If the key adding, programming, clearing, and immobilizer system construction parts replacement are performed, verify that the all keys can start the engine within 5 s after the procedure.
- When verifying that the engine starts, wait at least 5 s or more before starting the engine using the next key.
- If the engine cannot be started using a programmed key, repeat the procedure from the beginning.
- Do not start the engine unless indicated in the procedure. If the engine is started during the programming procedure, programming is stopped at that point. Repeat the procedure starting from the beginning if the engine is started before completion.
- Do not place the card key in the vehicle or bring it within approx. 1 m of the vehicle unless indicated in the procedure.
- Two or more key ID numbers must be programmed for the engine to start.
- A maximum of eight key ID numbers can be programmed for one vehicle. The M-MDS can be used to verify the number of key ID numbers programmed to a single vehicle.
- Do not select a M-MDS screen menu other than one indicated in the procedure.

M-MDS Connecting Procedure

CAUTION:
- Do not place the M-MDS in the vehicle while programming, otherwise programming cannot be performed.

1. Fully lower the door glass.

2. Connect the M-MDS to the DLC-2.






3. Pull out the M-MDS cable from the door glass opening and set the M-MDS outside the vehicle.

CAUTION:
- Protect the cable and body contact area with a clean rag, otherwise they could be damaged.

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

Condition
- Have two or more valid keys.

NOTE:
- A maximum of eight keys can be programmed for one vehicle. If key programming 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 programmed.
- If eight keys have already been programmed, and it is necessary to program other keys, the previously programmed key ID numbers must first be cleared. To clear the key, refer to "Clearing Card Key".

Procedure





1. Prepare key 3 for programming.

2. Start the engine using key 1.

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

4. Turn the ignition switch to the LOCK position.

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

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

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

12. Verify that the all keys can start the engine for 5 s or more after the procedure.

No. 2 Key Additional Programming Procedure (Using the M-MDS)

Condition
- There is only one valid key. Or, there is no valid key but there is a card key that can start the engine.

NOTE:
- A maximum of eight keys can be programmed for 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 programmed.
- If eight keys have already been programmed, and it is necessary to program other keys, the previously programmed key ID numbers must first be cleared. To clear the key ID number, refer to "Clearing Card Key".

Procedure (If one key is to be programmed)





1. Prepare key 2 for programming.

2. Start the engine using a valid key 1 or card key 1.
