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.
