Sunroof / Moonroof: Description and Operation

When the ignition switch is in ON or START, the power window relay is energized and applies battery voltage to the sunroof control unit. When the sunroof switch is held in the open position, the sunroof control unit supplies battery voltage to the sunroof motor and the sunroof opens to the vent position. At the moment the sunroof reaches the vent position, the tilt/safe switch closes and applies ground to the sunroof control unit. The sunroof control unit stops the sunroof in the vent position. After the sunroof switch is released and held in the open position, the sunroof motor opens the sunroof until it reaches its mechanical limit. When closing the sunroof, the roof stops 150 mm before the closed position instead of stopping in the vent position.
