Sunroof / Moonroof: Description and Operation

The Sunroof Control Module determines Sunroof Motor direction based on inputs received from the Sunroof Switch. Voltage is applied to terminals 10 and 4 of the Module, allowing Sunroof operation whenever the Ignition Switch is at RUN or during Retained Accessory Power.

Express Open

When the Sunroof Control Module's reverse/close vent input (terminal 8) is grounded through the Sunroof Switch, the Module will go into the express open mode. When the Module is in the express open mode, voltage is applied to the Sunroof Motor Assembly from terminals 6 and 12 of the Module. The Sunroof Motor's ground is through terminals 5 and 11 of the Module.
The Sunroof Motor will run until one of three conditions occurs: 1) the Motor stalls when the Sunroof reaches its fully open position, 2) the Sunroof Switch is pushed to the FORWARD/OPEN VENT position, or 3) the Sunroof Switch is released from the REVERSE/CLOSE VENT position and then pressed again.

Closing

When the Sunroof Control Module's forward/open vent input (terminal 2) is grounded through the Sunroof Switch, the Module will apply voltage to the Sunroof Motor Assembly from terminals 5 and 11. The Sunroof Motor's ground is through terminals 6 and 12 of the Module.
The Sunroof Control Module will run the Motor until the Sunroof Switch is released or the Limit Switch closes, grounding the Module's limit switch input (terminal 3). The Limit Switch will close when the Sunroof is in the flush closed position.

Vent

The Sunroof will move to the vent position when the Sunroof Control Module's forward/open vent input (terminal 2) is grounded when the Sunroof is in the flush position.

Express Close Vent

The Sunroof will move to the flush closed position when the Sunroof Control Module's reverse/close vent input (terminal 8) is grounded when the Sunroof is in the vent position. The Module will stop motor operation under the same conditions as outlined in express open.
