This bulletin describes and introduces new features of the Infiniti Vehicle Immobilizer System/Nissan Anti-Theft System (IVIS/NATS). The system is standard equipment on each of the applied vehicles listed above. The IVIS/NATS will not allow the engine to start without the use of a registered ignition key. If a vehicle will not start and the Security lamp is on solid, it may be because the ignition keys were not properly registered into the vehicle’s NATS IMMU (Immobilizer control unit). In this case, there will be a “DIFFERENCE OF KEY” code stored in the NATS IMMU. When the NATS ignition key, IMMU, or ECM (ECCS control unit) are replaced, C/U initialization is necessary. It is also necessary when registering keys and as part of many NATS Service Manual diagnostic procedures.
