FUNCTION

BGBDGCGD

When the doors are locked or unlocked by using the transmit-
ter, the dome light will flash/illuminate, the turn-signal lights will 
flash (hazard answerback), or the horn will sound (horn 
answerback) to inform the driver.
The hazard answerback and horn answerback functions can be

HOW TO REGISTER SECRET CODE

BGBHCCCB

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.

CAUTION

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.

SUNROOF ASSEMBLY

GENERAL DESCRIPTION

M1426000100234

A motor-driven inner slide-type glass sunroof with a 
tilt-up mechanism is available in some models as a 
standard or optional equipment. Even when the sun-
roof is fully closed, a sufficient amount of lighting and 
a feeling of openness can still be obtained by open-
ing the sunroof sunshade.

SUNROOF DIAGNOSIS

M1426000700311

The sunroof system is controlled by the Simplified 
Wiring System (SWS). Refer to GROUP 54B, SWS 
Diagnosis 

P.54B-57

.

SPECIAL TOOL

ON-VEHICLE SERVICE

WATER TEST

M1426000900274

Check if there are any leaks in the sunroof by the following pro-
cedure.
1. Fully close the roof lid glass.

2. Adjust the water pressure so that water comes out of the 

hose to a height of approximately 50 cm (19.7 inches) when 
the hose is held vertically facing upwards.

3. Hold the end of the hose approximately 30 cm (11.8 inches) 

above the roof and let the water run onto the weatherstrip for 
5 minutes or more.

4. Check if any water leaks can be found in the room while 

watering. Even though there are any water leaks around the 
roof lid glass, it can be acceptable as long as water is caught 
in the drip area.
