What is an ICU and SEC label?
An ICU and SEC label are stickers that are attached to the immobilizer control unit and smart entrance control unit of your car. These units are part of the NATS (Nissan Anti-Theft System) or IVIS (Infiniti Vehicle Immobilizer System) that prevent unauthorized start of the engine. The labels contain some information such as date code, encrypted PIN, serial number, and origin. You can find the ICU label under the dashboard near the steering column, and the SEC label under the glove box or behind the fuse box.
