KEYLESS ENTRY SYSTEM
GENERAL DESCRIPTIONBGBJABIE
Antenna and receiver are incorporated in the
ETACS-ECU.
ID code can be registered by using Diagnostic
tool (MUT-III).
Transmitter is a key holder type, which incorpo-
rates lock button, unlock button, trunk button and
panic button .
When the transmitter unlock button is pressed
once, the driver's door will be unlocked. If the but-
ton is pressed twice, all the doors will be
unlocked. The adjustment function also allows
you to open all the doors by pressing the unlock
button only once. For further details on using the
multi-center display to adjust the unlock opera-
tion, refer to GROUP 54B, On-vehicle Service
P.54B-486.
When the transmitter is operated, the answer-
back function will work as follows:
The answerback operation can be altered as fol-
lows:NOTE: Enabling/disabling the hazard warning
light flashing, the horn sounding in accordance
with the answerback function. For further details
on using the transmitter to adjust answerback,
P.42-72 see the section below. For further details
on using the multi-center display to adjust
answerback, refer to GROUP 54B, On-vehicle
Service P.54B-486. ITEM OPERATION

If none of the doors is opened or the ignition key
is not inserted in the ignition switch within 30 sec-
onds after the doors are unlocked using the
transmitter, the ETACS-ECU will relock the doors
automatically. This is called "Timer lock function."
This timer lock function prevents accidental
unlocking of doors. The adjustment function
allows you to change the timer lock period from 30 seconds (default setting) to 60, 120 or 180
seconds. For further details on using the
multi-center display (middle grade type) to adjust
the timer lock period, refer to GROUP 54B,
On-vehicle Service P.54B-486.
NOTE: The timer lock period begins when the doors
are unlocked, and ends when the doors is relocked
automatically.
KEYLESS ENTRY SYSTEM DIAGNOSISBGBCJGAI
The keyless entry system is controlled by the Simpli-
fied Wiring System (SWS). Refer to GROUP 54B,

HOW TO REGISTER SECRET CODEBGBHCCCB
Required Special Tools:
: MUT-III Sub Assembly
MB991824: Vehicle Communication Interface (V.C.I.)
MB991910: MUT-III Main harness A
Each individual secret code is registered inside the transmitter,
and so it is necessary to resister these codes with the
EEPROM inside 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 problem 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 previ-
ously registered codes for all transmitters are cleared. There-
fore, if you are using four transmitters or are adding more
transmitters, the codes for all transmitters must be registered at
the same time.
WHEN SPECIAL TOOL MB991824 (V.C.I.) IS USED
.
1. Check that the doors lock normally when the key is used.
2. Insert the ignition key.

KEYLESS ENTRY SYSTEM
BODY42-74
To prevent damage to special tool MB991824 (V.C.I.),
always turn the ignition switch to “LOCK” (OFF) position
before connecting or disconnecting special tool MB991824
(V.C.I.).
3. Connect special tool MB991824 (V.C.I.) to the data link
connector.
4. Press the hazard warning light switch six times within 10
seconds.
NOTE: When the hazard warning light switch has been
pressed six times, the ETACS-ECU locks and unlocks the
doors automatically once. The ETACS-ECU is ready to reg-
ister an encrypted code.
NOTE: The hazard warning light switch is a toggle switch.
5. Press the transmitter button, and then press it two times
within 10 seconds of the first press. This will register the
code.
6. When the encrypted code has been registered, the
ETACS-ECU locks and unlocks the doors automatically
once.
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 canceled under the following
conditions:
When the secret code for four transmitters has been regis-
tered;
When passing one minute after finishing the registration of
all transmitters;
When special tool MB991824 (V.C.I.) is disconnected;
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.
