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

id0914008050b1


Foreword

•  When performing the following procedures, the immobilizer resetting procedure using the WDS or equivalent must also always be performed: “Keyless control module replacement”, “PCM replacement”, “Steering lock unit replacement”, “Keyless control module and PCM joint replacement”, “Keyless control module, PCM, and steering lock unit joint replacement”, and “Key ID number clearing”. The engine will not start unless all work is performed using the WDS or equivalent.
•  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. (See CARD KEY ID CODE REGISTRATION [ADVANCED KEYLESS SYSTEM].)
•  There are two ways to add supplemental key: Using the WDS or equivalent 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 6).
•  Verify that the room fuse is equipped.

Ref. No.

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

―  Personal computer
―  Devices that can send/receive the radio waves
Note
•  The “valid key” used in this manual 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 WDS or equivalent can be used to verify the number of key ID numbers programmed to a single vehicle.
•  Do not select a WDS or equivalent screen menu other than one indicated in the procedure.

WDS or Equivalent Connecting Procedure

Caution
•  Do not place the WDS or equivalent in the vehicle while programming, otherwise programming cannot be performed.

1.  Fully lower the door glass.

2.  Connect the WDS or equivalent to the DLC-2.

3.  Pull out the WDS or equivalent cable from the door glass opening and set the WDS or equivalent 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)

Caution
•  Do not place the following devices in the vehicle while programming, otherwise programming cannot be performed:
―  Card key
―  WDS or equivalent
―  Personal computer
―  Devices that can send/receive the radio waves
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 WDS or equivalent 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 “No.3 PCM Replacement Procedure”.

Procedure

ar8wzw00001517

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.

8.  Remove key 1.

9.  Repeat Steps 2—5 using key 2 instead of key 1.

10.  Repeat Steps 5—8 using key 3 instead of key 1.

11.  If additional keys need to be programmed, repeat Steps 1—10, and replace key 3 in Step 10 with the key to be programmed (key 4).


No. 2 Key Additional Programming Procedure (Using the WDS or Equivalent)

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 WDS or equivalent 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 “No.3 PCM Replacement Procedure”.

Procedure

1.  Prepare key 1 for programming.

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

Caution
•  Do not place the card key in the vehicle when starting the engine with the valid key, otherwise programming cannot be performed. If the engine is started with the card key, remove the card key from the vehicle after the engine is started.

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.  Connect the WDS or equivalent to the DLC-2. (See WDS or Equivalent Connecting Procedure.)

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

Note
•  Although the security light flashes and DTC 15 is displayed, this does not indicate an improper procedure. Continue to perform the procedure as indicated.

7.  Select “BODY/SECURITY/PATS (immobilizer) function” from the WDS or equivalent screen menu.

8.  Select “Ignition key additional programming” from the WDS or equivalent screen menu.

Note
•  After selecting the above menu, “operation is successful” is displayed. At this point, the key that turned the ignition switch to the ON position is completely programmed.
•  In this procedure, the necessary number of the keys are completely programmed. To finish the additional key programming, go to Step 13.
•  If additional keys need to be programmed, go to the next step.

9.  Perform the security access according to the directions on the WDS or equivalent screen. (See SECURITY ACCESS PROCEDURE.)

10.  After verifying that the PATS function menu is displayed again on the WDS or equivalent screen, turn the ignition switch to the LOCK position and remove key 1.

11.  Using the key to be programmed, turn the ignition switch to the ON position.

12.  Return to the Step 6.

13.  After verifying that the PATS function menu is displayed again on the WDS or equivalent screen, select the “Finish (this menu)” to finish the WDS or equivalent procedure.

14.  After Step 10, wait 5 s or more, and then turn the ignition switch to the LOCK position.
