Sunroof / Moonroof: Description and Operation

When the starter 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 open relay energizes, supplying battery voltage to the Sunroof motor and the Sunroof opens to the limit stop position. At the moment the Sunroof reaches the limit stop position, the limit switch closes and applies ground to the Sunroof control unit. The Sunroof control unit stops the Sunroof in the limit stop 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 the Sunroof switch is held in the CLOSE position, the close relay energizes, supplying battery voltage to the Sunroof motor and the Sunroof opens to the safety stop position. At the moment the Sunroof reaches the safety stop position, the safety stop switch closes and applies ground to the Sunroof control unit. The Sunroof control unit stops the Sunroof in the safety stop position. After the Sunroof switch is released and held in the CLOSE position, the Sunroof motor closes the Sunroof until it reaches its mechanical limit.
