You need to call a your dealership. They will ask you for the serial number off the top of the stereo unit. To get to the serial number - First remove the consul by removing the two screws located underneath the radio. Just go to the edges of the radio and follow it down going underneath the dash. You will need a small Philips head as there isn't much clearance especially on the left side. You can then pull away the plastic exposing the radio itself. The serial number is on the top edge of the stereo on the left hand side.

Take you car-radio out. Get the serial # off the top of your radio. Call your Mitsubishi dealer, tell them you need a code, then give them your radios serial #. You should get a code too input. Should be a free-of-charge service. been told (haven't tryed) mess up 3 times - leave ignition on, radio on, engine not running for 45 minuted - should reset.

See my answer for another duplicate problem here: How do you reset the radio on a 2003 Honda accord -Bryan Mitsubishi stereo has a protection code. If you cut the power you better know the pass code. If you don't only Mitsubishi itself or its affiliates can help you. You might have to pay for it. There is online service which will send you your radio code for $30, but you have to provide the serial number your radio located on the top of radio.
