Circuit/System Description
The sunroof position select switch is connected directly to the controller. The sliding glass switch provide detent positions for open, express open, off, close, and express close. The sunroof position select switch completes the circuit between two signals provided by the control module, a reference ground input and a pull-up voltage provided by an analog to digital switch input. The control switch places a different resistor ladder network in the circuit depending on the function selected.
Description and Operation
SUNROOF DESCRIPTION AND OPERATION (SPOILER SYSTEM)
The sunroof glass is controlled by its own integrated motor/controller containing the necessary electronics, motor, hall effect position sensors, as well as the interface to the driver control switches. The motor/controller is capable of controlling motion based on control switch activation and LIN-Bus message commands from the body control module (BCM).
SUNROOF DESCRIPTION AND OPERATION (SPOILER SYSTEM)
The sunshade control switch is connected directly to the controller and provide detent positions for open, express open, off, close, and express close. The control switch completes the circuit between two signals provided by the control module, a reference ground Input and a pull-up voltage provided by the analog to digital switch input. The control switch places a different resistor ladder network in the circuit depending on the function selected. The controllers analog to digital switch input reads the resulting voltage range and determines the function.

SUNROOF DESCRIPTION AND OPERATION (SPOILER SYSTEM)
The sunroof electrical system uses a master/slave configuration utilizing a LIN-Bus based system for communication. The body control module (BCM) is designated as the master, while the sunroof and sunshade control modules are configured as the slaves.
As the system master, the BCM uses the LIN-Bus communication bus to enable or disable sunroof and sunshade operation, communicate vehicle information to each controller, and request sunroof or sunshade movement. The sunroof/sunshade controllers provide system status and diagnostic information to the BCM for diagnostic reporting and operational purposes. The control switches places a different resistor ladder network in the circuit depending on the function selected. The controllers analog to digital switch input reads the resulting voltage range and determines the function.
