HOW TO REGISTER SECRET CODE
M1428001000292
Each individual secret code is registered inside the
transmitter, and so it is necessary to resister these
codes with the EEPROM insi de the receiver in the
following cases.
•When the transmitter or ETACS-ECU is replaced
•If more transmitters are to be used
•If it appears that a probl em is occurring because
of faulty registration of a code.
A maximum of four different codes can be stored in
the EEPROM memory (four different transmitters can
be used). When the code for the first transmitter is
registered, the previously registered codes for all
transmitters are cleared. Therefore, if you are using
four transmitters or are adding more transmitters, the
codes for all transmitters must be registered at the
same time.

4. Press the hazard warning lamp switch six times
within 10 seconds.
NOTE: Once the process is completed six times,
then it will operate with al l doors and tailgate lock
and unlock operations once and then go to the
save mode.
NOTE: The hazard warning lamp switch is turned
on and off alternately whenever it is pushed.
5. Press the transmitter switch, and then press it two times within 10 seconds of the first press. This will
register the code.
6. Once the program is saved, it will operate once
with the all doors and tailgate lock and unlock
operations.
7. If you are using two or more transmitters or have
added a second transmitter, the next transmitter
should be registered within one minute after
registering the code for the previous transmitter.
The registration procedure is common for all the
transmitter.
8. Registration mode will be cancelled under the following conditions:
•When the secret code for four transmitters has
been registered;
•When no secret codes have been registered for
more than one minute after the registration mode
is entered;
•When passing one minute after finishing the reg-
istration of all transmitters;
•When the diagnosis connector is disconnected
from earth;
•When the key is removed from the key cylinder;
9. After the registration is completed, remove the ignition key and close all the doors, and then
check that the keyless entry system operates
normally.
WHEN THE M.U.T.-II IS USED
1. Check that the doors lock normally when the key
