2000 Cadillac Deville Emergency Brake release

Possibly a faulty solenoid, or problem with the release mechanism from the solenoid. It shows there are two relays controlled by the rear integration module. It could be any of these at fault as well. There is a white and a red wire at the solenoid that should receive power when the vehicle is put into gear, it does not have to be running. This will narrow it down to a solenoid fault, or suggest further diagnosis.
