Express Open

The express open will only operate with the sunroof in the fully closed or partially open position. To express open the sunroof glass, momentarily press the sunroof switch to the second rearward position once. This will apply the sunroof switch low reference circuit to both the sunroof switch express signal circuit and to the sunroof switch open signal circuit (12-volt references) inputs, pulling the them to 0 volts momentarily. The momentary transition inputs to the sunroof module indicates an express open request. Once the express open has been initiated, the sunroof module will drive the motor in the open direction, slightly lowering the rear edge of the sunroof glass, then sliding open with the sunshade, allowing the wind deflector to raise upward. The sunroof glass will continue to express open until:

• The sunroof glass reaches a predetermined (nearly full open) comfort stop position controlled by the limit switch.
• Activation of the sunroof switch (in any direction) to stop the sunroof glass in a desired position other than the express open (comfort stop) position.
• Motor stall is sensed because the sunroof glass is being obstructed.
• The operation time-out expires, 15 seconds after the initiation of the express open feature has been requested.
