Bought the car 2 yrs ago and put 5K miles on it (now 55K), 2003.
Everytime CC is initiated, the green light comes on followed by an amber light. holding down the on/off button (override ICC) does not work. It worked for me one time for about 10 seconds and I turned it off to try it again and it never worked again. As I understand it, holding down the on button will override the need for the IR sensor so even if that was damaged, it should still work as standard CC. I don't have anything. I have the service manual and have extensive electric background and troubleshooting but shooting blind here without a scan of the vehicle.
Also wondering about the Consult II software. I know the Nissan dealer has it BUT is there some other programming on them for the Infiniti stuff? IE, can I take the car to a Nissan dealer to get the body codes for the ICC system? I am sure once I know what it is detecting, it will help me find the problem.
