8. Check whether the transmitter encrypted code has been 

registered in the ETACS-ECU.
Connect special tool MB991824 (V.C.I.) to the data link 
connector. If the transmitter lock or unlock button is pressed, 
special tool MB991824 (V.C.I.) should sound once.
NOTE: If special tool MB991824 (V.C.I.) does not sound, the 
transmitter encrypted code has not been registered yet. 
Register the encrypted code again.
NOTE: If the code registration is difficult, refer to GROUP 
54B, SWS Diagnosis

.

9. 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 special tool MB991824 (V.C.I.) is disconnected;

• When the key is removed from the key cylinder;

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

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.

SUNROOF TIMER FUNCTION CHECK

M1426004300100

Keep the door closed, turn OFF the ignition switch and check to 
see if the sunroof can be operated for 30 seconds after that. If 
not, perform troubleshooting. (Refer to GROUP 54B, SWS 
Diagnosis 

P.54B-59

SUNROOF FIT ADJUSTMENT

M1426001000285

1. Fully close the roof lid glass.
2. Fully open the sunshade.
3. Loosen the roof lid glass assembly mounting screws. Align 

the roof lid glass by moving it backward, forward, up or down 
along the guide oblong hole so that the clearance between 
the glass and the vehicle body is even.

4. Check to be sure that the roof lid glass is flush with the roof 

panel at corner areas.

5. Check to be sure that the sunroof operates smoothly.

SUNROOF CHECK

M1426004700119

Check to see that the sunroof operates by pressing the sunroof 
switch. Perform troubleshooting if operations malfunction. 
(Refer to GROUP 54B, SWS Diagnosis 

P.54B-59

).

ROOF LID GLASS OPERATION CURRENT CHECK

M1426003200166

1. Remove the fuse of the sunroof, then connect the circuit 

tester as shown in the Figure.

2. Turn ON the sunroof switch, then measure the operating 

current when the roof lid glass is halfway opened.

Standard value: 7 A or less [at 20 

°C (68 °F)]

3. Check the following areas if the operating current of 

exceeds the standard value: 

• Sunroof installation, deformation and appearance of any 

foreign substances.

• Drive cable installation.

• Tilting of roof lid glass.
