MEMORY RESET PROCEDURE

1. Please observe the following instructions at confirming the moonroof operation.

NOTE:

Do not disconnect the electronic power while the moonroof is operating or within 5 seconds after the

moonroof stops. (to wipe-out the memory of lid position and operating friction.)

2. Initialization of system should be conducted after the following conditions.

• When the moonroof motor is changed.

• When the moonroof does not operate normally. (Incomplete initialization conditions)

quirement

INITIALIZATION PROCEDURE

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

tion to normal.

NOTE:

If the moonroof switch is released at any time during step 4, the procedure must be started over again. Leave

the ignition switch ON for at least 2 seconds after this procedure.

1. Push the ignition switch to the ON position.

2. Hold the moonroof switch in the close/tilt up position. Release the switch when the moonroof has reached

the full tilt up position and reverses slightly.

3. Push and hold the tilt up switch within 4 seconds of step 2. 

4. The moonroof will begin moving within 4 seconds. From the full tilt-up 

→ slide-close → slide-open →

slide-close 

→ tilt-up → slide-close. Release the switch, initialization is complete if the moonroof operates

normally.

ANTI-PINCH FUNCTION

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 in reverse for 150mm (5.91 in.) (approx.).

CAUTION:

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

pinched. 

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

roof it may lower.

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

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

operate normally.

MOONROOF MOTOR ASSEMBLY
MOONROOF MOTOR ASSEMBLY : Description

INFOID:0000000009756134

• BCM supplies power.

• CPU is integrated in moonroof motor assembly.

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

• In order to close moonroof lid certainly with the signal from combination meter at the time of high speed run,

the moonroof motor torque at the time of tilt-down operation is controlled.

Terminal No.
