Circuit/System Description
The sunroof switch is connected directly to the sunroof control module and provides detent positions for open, express open, off, close and express close. The sunroof switch completes the circuit between two signals proved by the sunroof control module, a reference ground input and a pull-up voltage provided by an analog to digital switch input. The sunroof switch places a different resistor ladder network in the circuit depending on the function selected.
