Default Trouble with the laser cruise control

Hi, I have an '05, and whenever I try to turn on the laser cruise control, it works, but when it detects a vehicle up ahead, it starts to freak out and disables the cruise control. It doesn't even give a code so that I can check it. The only thing I see is "Check Radar Cruise system" after it freaks out
I'd appreciate some insight on this matter!

check the sensor. if it is blocked it might do that
mine was broken. very expensive fix but might be why car was so cheap

Should be able to test it or see errors with Techstream. Not going to show up with generic obd2 scanner.
