ENCRYPTED CODE REGISTRATION METHOD
Each individual encrypted code is registered inside the
transmitter, and so it is necessary to register these codes
with the EEPROM inside the ETACS-ECU in the following
cases.
D When either the transmitter or ETACS-ECU is replaced;
D If a second transmitter is to be used;
D If it appears that a problem is occurring because of faulty
registration of a code.
A maximum of four different codes can be stored in the memory
area of the EEPROM (four different transmitters can be used).
When the code for the first transmitter is registered, the
previously-registered codes for four transmitters are cleared.
Therefore, if you are using more than two transmitters or are
adding a second transmitter, the codes for all the transmitters
must be registered at the same time.
1. Check that the doors lock normally when the ignition key
is inserted into the door key cylinder and turned.
2. Insert the ignition key in the ignition switch.
3. Connect the MUT-II to the diagnosis connector.
NOTE
This sets the system in encrypted code registration standby
mode. If MUT-II is not used, connect terminal No.1 of
the diagnosis connector to earth.
Caution
Always turn the ignition switch to LOCK (OFF) position
before connecting and disconnecting the MUT-II or
earth.
4. Within 10 seconds after connecting the MUT-II or earth,
press the hazard switch six times.
NOTE
(1) The doors will lock and unlock once after pressing
the hazard switch six times, and the system will switch
to registration mode.
(2) The hazard switch alternates between ON and OFF
each time pressing the hazard switch (Refer to
illustration).
5. Press the lock switch or unlock switch of the transmitter
switch, and then press it two times within 10 seconds
of the first press. This will register the code.
6. After registration is completed, the doors will be
automatically locked and unlocked once.
7. If you are using more than two transmitters or have added
a second transmitter, the same registration procedure
should be carried out for the remaining transmitters, and
it should be carried out within one minute after registration
of the code for the first transmitter has been completed.
The registration procedure are all the same for all
transmitters.
