Sunroof / Moonroof Limit Switch: Description and Operation

SUNROOF LIMIT SWITCHES

For the sunroof switch assembly to activate the sunroof motor and to allow sunroof switch requests, certain conditions have to be present. The sunroof switch assembly monitors the sunroof limit switch inputs. Once a sunroof limit switch is closed, the 12 volt reference will be pulled to 0 volts. The sunroof switch assembly understands the position of the sunroof glass position based on the input combinations from the sunroof limit switches. The sunroof switch assembly uses the sunroof limit switch input combinations to control the soft stopping of the sunroof glass in the flush closed and halfway closed positions and to disable certain sunroof switch requests.
