Immobilizer PIN Code for Nissan & Infinity vehicles
ICC can calculate 4 digit PIN Code for NATS (Nissan Anti Theft System) Immobilizers used in most of Nissan and Infinity vehicles made for USA, European and Asian markets, such as:

Infinity FX35, FX45, G20, G35, I30, I35, M35, M45, QX4, QX45, QX56, Q45 and others...
Nissan Altima, Almera, Armada, Frontier, Maxima, Cefiro, Murano, Merca, March, Micra, Navara, Note, Pathfinder, Primera, Patrol, Quest, Quashqai, Sentra, Teana, Titan, Terrano II, X-Terra, X-Trail, 350Z, Versa, Atlas, Cabstar, Tiida and others...
NATS also known as NVIS - Nissan Vehicle Immobilizer System and IVIS - Infiniti Vehicle Immobilizer System.

For calculating Immobilizer PIN code for Nissan or Infinity vehicle you need to know following information:

For USA made models with NATS5, NATS5.6, NATS6 immobilizer - 5 chars DOT serial number of BCM label (Body Control Module, p/n 284B1, 284B2) made in Japan by Calsonic Kansei Corp. For Siemens VDO.
For any models with NATS5 or NATS5.6 immobilizer - 6/4 chars serial numbers of ICU label (Immobilizer Control Unit, p/n 28590) made in Mexico or Germany by Siemens.
For any models with NATS6 immobilizer - 4/4 chars serial numbers of SEC label (Smart Entrance Control unit, p/n 28550) made in Europe by Siemens.
For 2003 Infinity Q45, M45 and probably some other models with NATS5 - 5 digit serial number from IMMU (Immobilizer Unit) label, p/n 28591.
For models with NATS7 immobilizer - such as Micra K12, Note and others - you need to read dump from BCM made by Johnson Controls or ECU and calculate code by dump.
In some other cases - 17 chars VIN (Vehicle Identification Number) also known as Chassis serial number of vehicle. Available only for some of USA, Mexico and Japan cars made in 1998-2005.
To identify NATS version - check label on ICU: STEP-5 means NATS-5, STEP-5.6 means NATS-5.6, STEP-6 means NATS-6 and STEP-7 means NATS-7.

In addition ICC can calculate immobilizer pin code from crypted code or by dump of EEPROM, includes NATS4, NATS5, NATS7. For pin codes by dump ICC will show also serial number of BCM or part no if available.

To calculate pin code by dump you need to locate and read (depend of car model and year):

ECU - 93C66
ICU - TMS370C032
BCM - 93C56, 93C66, 95080, MC9S12XDT384
For some modifications of Infinity Q45 / QX4 / FX35 / I30 / G20 and Nissan Altima / Maxima / Pathfinder / X-Terra vehicles you can use default NATS5 immobilizer PIN Code - "5523". Such vehicles have a big letter "A" on ICU label (Immobilizer Control Unit, p/n 28590-C9901).

Support for models with 12 digit codes based on Renault-Samsung platforms - SM3, SM5, SM7 and others will be added in near future. Most of this models are equipped with NATS-7. Current version of ICC can calculate codes for Micra K12 / Note by dump of EEPROM from BCM and ECU.

Seven various EEPROM structures (electronic units and their modifications) and 5 secret algorithms for Nissan and Infinity models are supported by current version of calculator.

Immobilizer PIN Code for KIA & Hyundai vehicles
ICC can calculate 6 digit Pin Code for SMARTRA (Smart Transponder Antenna) Immobilizer Control System aka ICS, read 5 digit Pin Code from eeprom dump for Texton immobilizer, read 4 digit Pin Code from dump of eeprom for Shin-Chang type of ICM for most of KIA and Hyundai vehicle models, such as:

KIA Rio, Sorento, Sephia, Mentor, Spectra, Cerato, Carnival, Sedona, Opirus, Sportage, Bongo, Shuma, Carens, Picanto, C'eed, Magentis, Optima, Amanti, K2700, 3000S, 2500TCI, K4000S, AM 928, Granbird, Multi-S, Sport, KCD, KCV, Pride and others...
Hyundai Accent, Matrix, Elantra, Grand Starex, Santa Fe, Trajet, Terracan, Tiburon, Getz, Coupe, Sonata, Grandeur, Tucson, H-1, XG, Atos Prime, Veracruz, HD65, HD72, HD78, HD120, HD160, HD250, HD320, H200, County, Cargo Truck, Aero Town, Gold, Verna and others...
