SECRET CODE REGISTRATION METHOD
Each individual secret code is registered inside
the transmitter, and so it is necessary to register
these codes with the EEPROM inside the receiver
in the following cases.

When either the transmitter or receiver is
replaced;

If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of two different codes can be stored
in the memory area of the EEPROM (two different
transmitters can be used). When the code for the
first transmitter is registered, the previously-regis-
tered codes for two transmitters are cleared.
Therefore, if you are using two transmitters or are
adding a second transmitter, the codes for both
transmitters must be registered at the same time.
Before beginning with the registration, check that
the doors lock normally when the key is used.
1. Connect the MUT-II to the diagnosis connector.
NOTE
This will connect terminal (1) of the diagnosis
connector to earth, and the system will be in
secret code registration standby mode.
Caution
Always turn the ignition switch to OFF before
connecting and disconnecting the MUT-II.
2. Close all the doors.
3. Turn the ignition switch to ACC and then back
to OFF.NOTE
The doors will lock and unlock once at this
time and the system will switch to registration
mode.
4. Press the transmitter switch, and then press
it two times within 10 seconds of the first press.
This will register the code.
5. After registration is completed, the doors will
be automatically locked and unlocked once.
6. If you are using two transmitters or have added
a second transmitter, the same registration
procedure should be carried out for the second
transmitter, and it should be carried out within
one minute after registration of the code for
the first transmitter has been completed. After
the second registration is completed, the doors
will be automatically locked and unlocked once.
7. Registration mode will be cancelled if one of
the following conditions is met.

When the secret codes for two transmitters
have been registered;

When 1 minute has passed after
registration mode started;

If the MUT-II is disconnected (the earth
connection is broken);

If the ignition switch is turned to ON;

If any of the doors are opened;
8. After registration is completed, carry out the
following to check if the keyless entry system
is operable properly.

Remove the ignition key.

Close all the doors.
