Sure, this code means there is a problem with the passenger side occupant detection ECU which can happen because it is low in the car and can get wet and fail.

DTC B1693: Passenger Airbag ON/OFF Indicator Circuit

Sometimes it will be the sensor itself, they can get weak and stay on which will trigger this code, but I have seen the ECU go out many times. Here is how to change the passenger side occupant detection ECU which should fix it, please clear the codes once completed. Check out the images (below). Let us know what you find.
