Narrative:

Departed dtw at approximately 9000 ft the cabin door warning light illuminated. Psi was around 3. I called for quick response handbook ditching/door, performed quick response handbook which called for us to reduce speed by raising the cabin. Also, it said land at nearest suitable airport. We did return to dtw. FAA has now called me in on this occurrence.
