REGISTRATION

PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

The key has 2 codes: the key code (immobiliser code) and the wireless code (recognition code). Both of these codes need to be registered. For wireless code registration procedures, refer to the following procedures (See page ). For key code registration procedures, refer
to the procedures below.

The key code is needed when the transponder key ECU, ECM or key is replaced with a new one.

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 key codes for 5 master keys and 3 sub-key can be registered.

4. KEY REGISTRATION PROCEDURES

(a) PROCEDURE "A"

New key code registration

HINT:

This mode operates normally when no key codes are registered in the transponder key ECU.

When a new transponder key ECU is installed, key codes must be registered in the transponder key ECU.

In this mode, a maximum of 3 key codes for 2 master keys and 1 sub-key can be registered. The master keys and sub-key can be registered in any order because the transponder key ECU can distinguish between different types of keys.

New key codes must be registered with the battery connected. The ignition switch can be either ON or off.

Procedure	Security Indicator Light Condition
1. Start registration	Security indicator light is blinking
2. Insert one of master keys into ignition key cylinder	Security indicator light turns on
3. Enter the following menus: (1) Body Electrical (2) Immobiliser (3) Utility (4) Key Registration HINT: After above operation, proceed to next step in accordance with prompts on screen	Security indicator light turns off for 1 sec. and then turns on
4. Remove key	Security indicator light turns on HINT: When maximum number of key codes is registered, security indicator light remains off until last key registered is removed. After it is removed, security indicator light starts blinking.
5. Register another key? YES: Go to step 6 NO: Go to step 7 HINT: Key codes for maximum of 2 master keys and 1 sub-key can be registered
6. Insert another key into ignition key cylinder. Then go to step 4.	Security indicator light turns off for 1 sec. and then turns on
7. End of registration

(1) End new key code registration mode (when not using the Techstream)

HINT:

Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key is registered.

Turn the ignition switch to ON and LOCK 5 times within 10 seconds using a master key that is already registered.

(2) End new key code registration mode (when using the Techstream)

HINT:

Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key is registered.

Insert the key into the ignition key cylinder and turn the Techstream on.
Follow the instructions on the Techstream screen to end new key code registration mode.
HINT:
- When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
- If new key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister an already registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light.

(b) PROCEDURE "B"

Additional key code registration

HINT:

At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
In this mode, a maximum of 5 master key codes and 3 sub-key codes can be registered.
This mode ends if each step is not completed within the specified time.
When the ignition key cylinder or the ignition key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.

NOTICE:

When only the ignition key cylinder is replaced, the new key cannot be used to lock or unlock doors. Therefore, keep the original key for locking and unlocking doors in order to avoid being locked out of the vehicle if the transmitter battery becomes depleted.

Procedure	Security Indicator Light Condition	Time (Completion of Operation)
1. Start registration	Security indicator light is blinking	-
2. Insert an already registered master key into the ignition key cylinder, turn the ignition switch to ON, and turn the Techstream on	Security indicator light turns off	-
3. Enter the following menus: (1) Body Electrical (2) Immobiliser (3) Utility (4) Key Registration HINT: After above operation, proceed to next step in accordance with prompts on screen	Security indicator light turns on	-
4. Perform following operation: (1) Remove master key from ignition key cylinder (2) Insert master key back into ignition key cylinder (3) Turn ignition switch to ON (4) Push Next on the Techstream	Security indicator light turns on	Within 120 sec. of instruction on the Techstream
5. Remove master key, and then push Next on the Techstream	Security indicator light turns on	Within 20 sec. of instruction on the Techstream
6. Insert unregistered key into ignition key cylinder, and then push Next on the Techstream	Security indicator light is blinking HINT: Registration is being performed	Within 10 sec.
7. After 60 sec., key is registered HINT: Security indicator light turns off	Security indicator light turns off	-
8. Screen displays number of registered keys
9. Register another key? YES: Go to step 2 NO: Go to step 10
10. End of registration

HINT:

A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the screen of the Techstream.
When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
If additional key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister a previously registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown in procedure "B".

Clear all key codes except master key

HINT:

All key codes are cleared except for the master key which is used for clearing the key codes. In order to use a key whose code is cleared, a new key code must be registered.
At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.

Make sure the inserted key is a registered master key.
