[Comment]When the PANIC switch is pressed, the receiver sends a PANIC signal to ETACS-ECU. Then the ECU flashes the headlights and sounds
the horns intermittently for approx. three minutes.
The headlights and horns share an operation circuit with the theft-alarm system. Because of this, if the theft-alarm system functions normally,
the
harness between the receiver and the ETACS-ECU mav be defective.

Entry System
METHOD OF REGISTERING A SECRET CODE
Each individual secret code is registered inside the transmitter,
and so it is necessary to register these codes with the received
in the following cases.
lWhen either the transmitter or receiver is replaced;
lIf a second transmitter is to be used;
lIf it appears that a problem is occurring because o f faulty
registration of a code.
A maximum of two different codes per transmitter ca n be
stored in the memory area of the EEPROM, and up to two
different transmitters can be used. When the codes for the
first transmitter are registered, the previously-registered codes
for both transmitters are cleared. Therefore, if yo u are using
two transmitters or are adding a second transmitter , the
for both transmitters must be the same time.
(1) Check that the door locking function works norm ally using
the door key.
(2) Connect the scan tool to the data link connecto r.
NOTE
This grounds the data link connector
and gets ready
for a code registration.
Caution
Turn the ignition switch to OFF before connecting
or disconnecting the scan tool.
(3) Close all doors.
(4) Turn the ignition switch to ACC and return it t o OFF.
NOTE
This locks and unlocks the door once, and then a co de
can be registered.
(5) After pressing any switch on the transmitter on ce, press
it two more times within 10 seconds to register the same
code for SET I and SET II.
(6) After registration is completed, the doors will automatically
be locked and unlocked once.
(7) If you are using two transmitters or have added asecond
transmitter, the same registration procedure should be
carried out for the second transmitter, and it shou ld be
carried out within one minute after registration of the codes
for the first transmitter has been completed. After the
second registration is completed, the doors will au tomati-
cally be locked and unlocked once.
(8) Registration mode finishes under the following conditions.
lRegistration of two transmitter codes are completed .
lOne minute has passed since the registration mode
setting.
l Scan tool is disconnected. (ground released.)
l Ignition switch is turned ON.
l Any of the doors are opened.
