open the tailgate (the tailgate lock release handle 
switch turns ON) while the vehicle is parked and the 
tailgate is unlocked, ETACS-ECU turns the unlock 
relay output ON for 0.3 seconds, thus the tailgate 
can be opened by the tailgate lock release handle.

• By using the lock/unlock switches, the driver can 

lock/unlock all the doors (including tailgate), 
fold/unfold the door mirrors.

•

NOTE: Using a customisation function, the oper-
ation of the door mirrors can be enabled or disa-
bled (Refer to 

P.42A-38

).

DESCRIPTION OF STRUCTURE AND 
OPERATION

TRANSMITTER

•

The transmitter is integrated into the master key.

• When either switch is pressed, the transmitter 

emits a radio signal representing a specific ID 
code.

• There are two switches on the transmitter; the 

lock switch and the unlock switch.

• An indicator lamp, which illuminates when signals 

are transmitted, is added on the key grip. This 
indicator lamp informs you of the signal transmis-
sion status and warns you of flat battery.

• A brilliant silver Three-diamond mark is stamped 

on the back side of the key grip to improve 
appearance.

• A signal transmission circuit (printed circuit) and 

a battery are housed in one case. The case is 
housed in the key grip, thus improving resistance 
to water ingress.

• A coin type battery, CR1616 is used in the trans-

mitter.

• The transmitter switch operation allows the sys-

tem to operate as follows:

POWER DOOR LOCKS WITH SELECTIVE 
UNLOCKING 

• Responding to the adoption of power door locks 

with selective unlocking, the anti-theft feature has 
been improved.

• When the lock/unlock switch of front door 

(driver's side) is pressed once, only the driver's 
door is unlocked. When the lock/unlock switch of 
front door (driver's side) is pressed once again 
within 2 seconds after the driver's door is 
unlocked, the front passenger's door, rear doors, 
and the tailgate are unlocked.

• When the unlock switch on the transmitter is 

pressed once, only the driver's door is unlocked. 
When the transmitter unlock switch is pressed 
once again within 2 seconds after the driver's 
door is unlocked, the front passenger's door, rear 
doors, and the tailgate are unlocked.

• Using a customisation function, the power door 

locks with selective unlocking can be enabled or 
disabled (Refer to 

P.42A-38

).

ENCRYPTED CODE

The figure shows the codes transmitted from the 
transmitter. Every time the switch is pressed, the 
data code is transmitted twice. The encrypted code 
for user identification is a combination of 0 and 1, 
and more than 1 million different combinations are 
available. In addition to the encrypted code, the data 
code contains a rolling code that changes at each 
transmission, protecting transmission codes from 
theft by coping.

RECEIVER ANTENNA

The receiver antenna receives the signal from the 
transmitter and sends the signal to the ETACS.

ETACS-ECU

ETACS-ECU compares the signal the receiver 
antenna received from the transmitter with the 
encrypted code registered in it, and when they coin-
cided, operates keyless entry function (door lock, 
unlock, etc.). By connecting M.U.T.-III to the diagno-
sis connector, encrypted codes of up to eight trans-
mitters can be registered.

FUNCTION FOR CONFIRMING 
ETACS-ECU OUTPUT AND OPERATION

The ETACS-ECU outputs LOCK/UNLOCK signal 
and informs the driver of the keyless entry system 
operation by flashing the lamp (Answer-back). Using 
a customisation feature, the flashing patterns for the 
answer-back function can be changed according to 
the table below. The initial setting at factory for the 
answer-back function is as follows: "Hazard warning 
lamp: LOCK, Flash once, UNLOCK, Flash twice / 
Room lamp: LOCK, Flash once, UNLOCK, Stay on 
for 15 seconds." Using a customisation feature, the 
hazard answer-back function can be changed (Refer 
to 

P.42A-38

).

Multi mode 
function

Press the lock switch once to lock all doors 
(including the tailgate), and within 30 
seconds press the lock switch twice 
consecutively.

The door mirrors are retracted.

Press the unlock switch once to unlock all 
doors (including the tailgate), and within 
30 seconds press the unlock switch twice 
consecutively.

The door mirrors return to the original 
position.

Power door locks 
with selective 
unlocking

Press the unlock switch once to unlock the 
driver’s door, and within 2 seconds, press 
the unlock switch again to unlock the front 
passenger’s door, rear doors and tailgate.

Power door locks with selective unlocking.

NOTE: Using a customisation function, the 
power door locks with selective unlocking 
can be enabled or disabled.

DOOR AND TAILGATE

BODY

42A-15

KEYLESS ENTRY HAZARD LAMP 
ANSWERBACK FUNCTION

When LOCK signal from the keyless entry transmit-
ter is input to the ETACS-ECU, all doors (including 
tailgate) are locked and the hazard warning lamp 
flashes once. When UNLOCK signal is input, all 
doors (including tailgate) are unlocked and the haz-
ard warning lamp flashes twice.

KEYLESS ENTRY ROOM LAMP ANSWER-BACK FUNCTION

When the LOCK signal from the transmitter is input 
to ETACS-ECU via the receiver antenna, all doors 
(including tailgate) are locked, and the room lamp is 
turned off in synchronisation with hazard lamp 
answerback (when the room lamp is illuminated, the 
lamp is turned off). Also, when the UNLOCK signal 
from the transmitter is input to ETACS-ECU via the 
receiver antenna, all doors (including tailgate) are 
unlocked, and the room lamp is illuminated for 15 
seconds in synchronisation with hazard lamp 
answerback.

KEYLESS ENTRY TIMER LOCK TIME

If any door is not opened or closed within 30 seconds 
after the doors (including tailgate) are unlocked by 
the keyless entry system, ETACS-ECU automatically 
outputs the door lock signal to lock the doors (includ-
ing tailgate). This function prevents the doors (includ-
ing tailgate) from being unlocked unexpectedly by 
operation errors. Using a customisation feature, the 
keyless entry timer lock time can be changed (Refer 
to 

P.42A-38

).

OPERATION INHIBITION CONDITIONS

The operation of the keyless entry system is inhibited 
in the following conditions.

• When the ignition key is inserted into the ignition 

switch.

• When either door (including tailgate) is open (the 

door switch: ON). (including door ajar)
