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 two or more transmitters or are adding
more transmitters, the codes for all transmitters must be regis-
tered at the same time.

When special tool MB991529 is used

1. Insert the ignition key into the key cylinder and check that

the doors have been locked normally when the ignition key
is turned.

2. Insert the ignition key into the key cylinder.

CAUTION

Turn the ignition switch to the "LOCK" (OFF) position and
then connect data link connector terminal 1 to ground.
3. Connect the data link connector terminal 1 to ground.

NOTE: Connecting terminal 1 of the data link connector to
ground will put the system in secret code registration
standby mode.

4. Push the hazard warning light switch six times within 10

seconds.
NOTE: At this time the code registration monitor request is
output and becomes registration mode (all doors locked and
then all doors unlocked).
NOTE: The hazard warning light switch is turned on and off
alternately whenever it is pushed.

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 registration is completed, the code registration

monitor request is output (all doors locked and then all doors
unlocked).

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. After the second registration is
completed, the code registration monitor request is output
(all doors locked and then all doors unlocked).

8. Registration mode will be canceled under the following

conditions:

• When the secret code for four transmitters has been regis-

tered;

• When one minute has passed after registration mode

started;

• When the data link connector terminal 1 to ground is dis-

connected;

• When the ignition key is removed from the ignition key cylin-

der;

9. After the registration is completed, carry out the following.

CAUTION

Turn the ignition switch to the "LOCK" (OFF) position and
then disconnect data link connector terminal 1 from
ground.
10.Disconnect data link connector terminal 1 from ground.
11.Remove the ignition key from ignition key cylinder.
12.Close all of the doors.
13.Verify the keyless entry system operates normally.
