REGISTRATION
HINT:
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 DL-
46). For key code registration procedures, refer to the
procedures below.
1. DESCRIPTION OF CODE REGISTRATION
(a) When adding master keys and sub-keys (additional
registration).
(1) Register the key codes in the transponder key
ECU.
(b) After replacing the transponder key ECU (new key
code registration).
(1) Register the key codes (immobiliser code) in
the new transponder key ECU.
(2) Register the ECU COMMUNICATION ID
between the ECM and the new transponder
key ECU.
(c) After replacing the ECM.
(1) Reregister the ECU COMMUNICATION ID
between the new ECM and the transponder
key ECU.
(d) After replacing the transponder key ECU and ECM.
(1) Register the ECU COMMUNICATION ID
between the new ECM and the new
transponder key ECU.
(e) Erasure of key codes.
(1) Erase the key code(s) of the lost key(s).
2. NEW KEY CODE REGISTRATION (PROCEDURE "B")
(a) New key code registration
Condition:

HINT:
• 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.
• When a new transponder key ECU is installed,
key codes must be registered in the transponder
key ECU.
HINT:
• The new key code registration mode can be
deliberately ended by following procedure A or B
below when the battery is connected, and at
least 1 key code for the master key has been
registered.
(a) Insert the key into the ignition key cylinder and
turn the intelligent tester on.
(b) Follow the instructions on the intelligent tester
screen to end the new key code registration
mode.
(c) New key code registration mode ends.
• When the engine immobiliser system is operating
normally and the key is pulled out, the security
indicator light blinks continuously.
• If the new key code registration fails, code 2-1 is
output by the security indicator light. Trying to re-
register 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. The output details are shown below.

3. REGISTRATION OF ADDITIONAL KEY (PROCEDURE
"A")
HINT:
• A maximum of 5 master key codes and 3 sub-key
codes can be registered.
• Additional key code registration mode ends if each
step is not completed within the specified time.
• When proceeding to the next step while the timer is
running, the timer is reset and begins the countdown
for the next step.
• 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 the ignition key cylinder has been replaced,
locking and unlocking doors are possible with the
new master key once the transmitter module from
the original master key has been transferred to it.
However, the new master key will not be able to lock
and unlock doors through the door key cylinder.
Keep the original master key. If the new master key's
transmitter module battery fails, the original master
key can be used to lock and unlock doors through
the door key cylinder.
(a) Additional key code registration
Condition:
At least one key code must be registered in the
transponder key ECU.

HINT:
• If the key is removed within 60 seconds in step 6,
the additional key code registration mode is
canceled.
• A brief outline of the procedures for key code
registration is shown above. For more detailed
information, refer to the intelligent tester screen's
instructions.
• When the engine immobiliser system is operating
normally and the key is pulled out, the security
indicator light blinks continuously.
• If the 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".
4. ERASURE OF KEY CODE (PROCEDURE "D")
HINT:
All key codes are erased except for the master key,
which is used for erasing the key codes. In order to use a
key whose code has been erased, a new key code must
be registered.
(a) Erasure of key code
Condition:
At least two key codes must be registered in the
transponder key ECU.

HINT:
• To cancel erasure mode after the erasure
request is sent from the tester to the ECU, leave
the master key inserted until the timer times out.
• A brief outline of the procedures for key code
erasure is shown above. For more detailed
information, refer to the intelligent tester screen's
instructions.
• When the engine immobiliser system is operating
normally and the key is pulled out, the security
indicator light blinks continuously.
5. ECU - ECM COMMUNICATION ID REGISTRATION
(PROCEDURE "C")
NOTICE:
• The ECU communication ID should be registered
when the transponder key ECU and / or ECM is
replaced in order to match the ECU - ECM
communication ID.
• The engine cannot be started unless the ECU -
ECM communication ID matches.
• Do not disconnect the battery while the ECU -
ECM communication ID is being set.
• Do not turn the ignition switch from ON to OFF 20
times or more before setting the ECU - ECM
communication ID. If this operation is likely to be
performed 20 times or more, disconnect the
negative battery terminal cable in order to avoid
engine start disablement. Failure to do so will
result in the engine not starting unless the
transponder key ECU is replaced with a new one.
(a) After replacing the transponder key ECU
(1) Register the key code(s) by following the new
key code registration procedure (procedure
"B").
(2) Using SST, connect the TC and CG terminals
of the DLC3 before inserting the key into the
key cylinder.
