TRANSMITTER

The transmitter, separated from the keys, features three but-
tons lock, unlock and trunk signals <Vehicles without panic
alarm system> or four buttons lock, unlock, trunk and panic sig-
nals <Vehicles with panic alarm system>.
Transmitter operations also function as distinctive cipher codes
that are sent to the ETACS-ECU as electronic signals.

CIPHER CODE
Operating the transmitter once for locking or unlocking will
send a data code twice. The cipher codes that identify users
are made up of combinations of 0 and 1. There are over a mil-
lion combinations. To prevent theft by copying signal codes, the
data code includes a rolling code with the cipher code. The roll-
ing code changes each time a signal is sent.

RECEIVER (PART OF ETACS-ECU)

The ETACS-ECU has a receiver with an antenna.
The receiver compares the code sent from the trans-
mitter with the code retained in the receiver through
the antenna.

•

The ETACS-ECU sends a signal only when those
two codes correspond and the rolling code is
judged correct.

•

All of those output signals are processed inter-
nally in the ETACS-ECU.

•

A maximum of four cipher code (4 transmitters)
can be registered by connecting the data link
connector to the MUT-III sub-assembly
MB991958.

ANSWERBACK FUNCTIONS

An answerback function is used to notify users after
the receiver receives the stored ID code signal and
the ETACS-ECU sends the lock or unlock signal. The
lights flash or the horn honks to confirm the opera-
tion. The factory-set default answerback setting is
described in the following table. The transmitter and
the multi-center display (middle-grade type) can be
adjusted to change the response after locking and

unlocking. Owners can adjust whether or not the
turn-signal lights, dome light, flash or are illuminated,
as well as whether or not the horn honks. For further
details on using the transmitter to adjust answer-
back, see the section below. For further details on
using the multi-center display (middle-grade type) to
adjust answerback, refer to GROUP 54B, Simplified
Wiring System

The ETACS-ECU tone alarm will sound
once.

•

Disable the horn answerback function:
The ETACS-ECU tone alarm will sound

three times.

NOTE:

*: The horn will sound if the doors are already

locked and the keyless entry lock button is

the keyless entry system.

TIMER LOCK FUNCTION

After the transmitter is used to unlock the doors
(including the liftgate), if no door is opened and the
ignition key is not inserted within 30 seconds, the
ETACS-ECU automatically sends a door lock signal
to lock all doors (including the liftgate). This timer
lock function prevents operational error from acci-
dental unlocking of doors and the liftgate. The default

period for the timer lock function is factory-set at 30
seconds, but it can be adjusted to settings of 30, 60,
120, and 180 seconds using the multi-center display
(middle-grade type). For further details on using the
multi-center display (middle-grade type) to adjust the
timer period, refer to GROUP 54B, Simplified Wiring

A powered sliding sunroof that can be tilted is avail-
able. The sunroof offers the following advantages:

•

The sunroof opens wide.

•

The sunroof tilts up approximately 30 mm (1.18
inches) to improve ventilation.

•

A single switch is added to the overhead console
for convenient one-touch operation of all position-
ing: sliding the sunroof open and closed, tilting it
up and down, and setting the position.

•

The system features a function to open approxi-
mately 30 mm (1.18 inches) every time the
close/tilt down switch is pressed, until the sunroof
is fully open, by canceling the jam prevention
mechanism:

•

It is possible to operate the sunroof for 30 sec-
onds even after the ignition switch is turned OFF.
(The key-off function stops when the front door is
opened).
