If consciousness is just the process of reading the last ~400 milliseconds [1] of stimuli (inside: pain/pleasure/presence; outside: presence only) and the integration of the newly created memory in the short/long-term-memory, and if memory + retro/pre-diction = intelligence, where memory is just a set of words (FELT PAIN, SEEN SUN, etc.) always-ready to be inserted in the prediction loop/imagination engine, it's probably not that hard to isolate a module of consciousness (italicized words to be read with a Minsky-ian smile thinking vision could be solved in a summer).
