Sunroof Switch - Operation

OPERATION

Both the power sunroof and (if equipped) the power sunshade switch are hard wired to the electronic module integral to their respective power sunroof or power sunshade motor. The electronic module provides the switch with a source current whenever the ignition switch is in the ON or ACCESSORY positions. When one of the switch push buttons is depressed, it sends a signal back to the electronic module and the electronic module controls the motor to move the sunroof or sunshade panel to the appropriate position.

A short duration (less than 800 milliseconds) press of the switch push button is interpreted by the electronic module as an Express (also known as one touch) command, where the motor will automatically move the glass panel or sunshade to the fully open, fully closed or (sliding glass panel only) the ventilation position. A long duration (greater than 800 milliseconds) press of the push button is interpreted by the electronic module as a manual command, where the motor moves only as long as the push button is held in the depressed position. During an Express event, any new switch input will immediately stop an in-progress event which, as in the manual mode, allows the customer to stop the sliding glass panel or sunshade at any desired location.

The power sunroof and power sunshade switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
