Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
The sunroof control module supplies each of the sunroof switch signal circuits with a 12-volt reference. When a switch is pressed the signal circuit is pulled low signaling the sunroof open or close request. The module determines the motor direction based on inputs received from the sunroof switch. When the module reverses the polarity of the applied voltage, the motor reverses direction. A sunroof enable signal is supplied to the sunroof control module by the BCM. B+ is applied to the sunroof control module via the L/GATE/S/ROOF fuse.
