That's the ticket. There are capacitors in the control modules to maintain memory during a short term power outage (eg, installing a new battery). It takes a while for the capacitors to discharge. Sending power to the brake lamps accelerates the process.
If you step on the brake pedal, it only takes a second or two to completely drain the system. Keep your foot on the pedal for, say, 10 seconds, just to be sure.
If that doesn't make the light go away, get an OBD tool and see if any PIDs are present. Do a web search for the PIDs and/or post them in this thread.
Many auto parts stores will loan you an OBD tool; some will even walk out to your car and grab the PIDs for you. If you plan on working on your car, you can buy simple OBD tools for $20-40.
