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.
