I had same problem, was told I need a Nissan computer diagnosis,but read that there are 3 main problems unassociated with software..3 switches disengage cruise control, brake,clutch and gearbox. My problem is the clutch pedal switch.I can reset it by putting my left foot under the clutch pedal and lift it to the max upward travel,which re-sets the switch.I could always get the green dash lamp to show cruise,but the toggle switch on the steering wheel which resets cruise made no difference until I lifted the clutch pedal up. It works fine now.
