INITIALIZATION PROCEDURE 

Moonroof 

If the moonroof does not open or close automatically, use the following procedure to return moonroof opera-

tion to normal.

1. Turn ignition switch ON.

2. Push and hold the moonroof tilt switch forward until the moonroof stops. 

3. Release the moonroof switch.

4. Press and hold the tilt up switch within 6 seconds. 

5. The roof glass will Tilt-Down

→ Slide-Close → Slide-Open → Slide-Close → Tilt-Up → Tilt-Down. 

6. Release the switch, initialization is complete if the moonroof operates normally.

Sunshade

If the sunshade does not open or close automatically, use the following procedure to return sunshade opera-

tion to normal.

1. Switch the vehicle ignition to the ACCESSORY or RUN mode.

2. Press and hold the sunshade close switch.

3. Sunshade will begin moving towards the close position only while the switch is continually pressed. (this

disables the obstacle detection).

4. Sunshade will stop for about 4 seconds.

5. Sunshade drive cable will travel in the open direction for 10 mm (.394 in.) then reverse direction and stop

at the normal close position.

6. Release the sunshade close switch. Initialization procedure is complete. 

ANTI-PINCH FUNCTION

Moonroof

1. Fully open the moonroof to the full open position.

2. Place a piece of wood at the fully closed position.

3. Close the moonroof completely with auto-slide close function. 

4. Moonroof should make contact and then tilt up or travel in reverse for 125mm (4.92 in.). 

Sunshade

1. Open the sunshade to the full open position.

2. Place a piece of wood at the fully closed position. 

3. Close the sunshade completely with auto-slide close function.

4. Sunshade should make contact and then travel in reverse for 100mm (3.94 in.). 

CAUTION:

• Do not test the anti-pinch function with your hands or other body parts because they may be

pinched. 

• Depending on the environment and driving conditions, if a similar impact or load is applied to the

moonroof it may lower.

• Test the auto-slide operation before inspection when the initialization procedure is performed.

• Perform the initialization procedure when the auto-slide operation or anti-pinch function does not

operate normally.

BCM
BCM : Diagnosis Procedure

INFOID:0000000009764004

Regarding Wiring Diagram information, refer to 

BCS-55, "Wiring Diagram"

.

1.

 CHECK FUSE AND FUSIBLE LINK

Check that the following fuse and fusible link are not blown.

Is the fuse or fusible link blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Disconnect BCM connector M81.

2. Check voltage between BCM connector M81 terminals 131, 139 and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Repair or replace harness or connectors.

3.

 CHECK GROUND CIRCUIT

Check continuity between BCM connector M81 terminals 134, 143 and ground.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Repair or replace harness or connectors.

MOONROOF MOTOR ASSEMBLY
MOONROOF MOTOR ASSEMBLY : Description

INFOID:0000000009176290

• BCM supplies the moonroof motor assembly with power.

• CPU is integrated in moonroof motor assembly.

• Tilts up/down & slides open/close by moonroof switch operation.

• In order to close the moonroof during high speed driving, the Combination meter will send a speed signal to

the moonroof CPU to adjust the torque of the motor during the tilt-down operation. 

Terminal No.
