ETACS-ECU buzzer will sound twice.

HOW TO REGISTER SECRET CODE

M1428001000474

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 THE SPECIAL TOOL V.C.I. 
(MB991824) 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 V.C.I., 
turn the ignition switch to the "LOCK" (OFF) 
position.

3. Connect the V.C.I. to the diagnosis connector.

4. Within 10 seconds after turning the V.C.I. power 

switch to the "ON" position, press the hazard 
switch six times.
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.
