The hazard answerback function can be enabled or 
disabled by one of the two following procedures.
<When using the transmitter after diagnosis 
connector (1) is earthed>
1. Enter the hazard answerback customize mode by 

performing one of the following steps. If the

least ten seconds. Then the ETACS-ECU 
buzzer will sound once.

2. If the transmitter “LOCK” button is pushed 

consecutively twice (within two seconds), the 
ETACS-ECU buzzer will sound, indicating that the 
hazard answerback function can be enabled or 
disabled when the doors are locked.

•

when the doors are locked: The 
ETACS-ECU buzzer will sound once.

•

Disable the hazard answerback function 
when the doors are locked: The 
ETACS-ECU buzzer will sound twice.

3. If the transmitter “UNLOCK” button is pushed 

consecutively twice (within two seconds), the 
ETACS-ECU buzzer will sound, indicating that the 
hazard answerback function can be enabled or 
disabled when the doors are unlocked.

when the doors are unlocked: The 
ETACS-ECU buzzer will sound once.

•

Disable the hazard answerback function 
when the doors are unlocked: The 
ETACS-ECU buzzer will sound twice.

4. Exit the hazard answerback customize mode by 

observing one of the following steps.
(1) Disconnect diagnosis connector terminal (1) 

form the earth.

(2) Turn the ignition switch to position other then 

“LOCK”(OFF), or remove the ignition key.

(3) Open the driver's side door,
(4) Any other warning buzzer output occurs.

NOTE: If any operation is not done for at least three 
minutes after the ETACS-ECU has entered the 
customize mode, the hazard answerback customize 
mode will be canceled automatically.

HOW TO REGISTER SECRET CODE

M1428001000418

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 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.

When special tool diagnosis code check 
harness MB991529 is used

1. Check that the doors lock normally when the key 

is used.

2. Insert the ignition key.

CAUTION

Before connecting or disconnecting the earth, 
turn the ignition switch to the "LOCK" (OFF) 
position.

3. Connect the diagnosis connector to the special 

tool diagnosis code check harness MB991529.
NOTE: This will connect terminal (1) of the 
diagnosis connector to earth, and the system will 
be in secret code registration standby mode.

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 all 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 same registration 
procedure should be carried out within one minute 
after registering the code for the first transmitter.

8. Registration mode will be canceled under the 

following conditions:

•

When the secret code for four transmitters has 
been registered;

•

When one minute has passed after registration 
mode started;

•

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.
