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

• Infiniti FX35, FX45, FX50, G20, G35, G37, I30, I35, M35, M45, QX4, QX45, QX56, Q45, EX35, EX37 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 Infiniti vehicle you need to know following information:

• for USA made models with NATS5, NATS5.6, NATS6 immobilizer - 5 chars crypted code from BCM label (Body Control Module, p/n 284B1, 284B2) made in Japan by Calsonic Kansei Corp. for Siemens VDO.
• for models with NATS5, NATS5.6, NATS6 immobilizer - 5 chars crypted code readed with an diagnostic equipment like AD100Pro, Carman Scan and others.
• for any models with NATS5 or NATS5.6 immobilizer - 6/4 chars crypted code from ICU label (Immobilizer Control Unit, p/n 28590) made in Mexico or Germany by Siemens.
• for any models with NATS6 immobilizer - 4/4 chars crypted code from SEC label (Smart Entrance Control unit, p/n 28550) made in Europe by Siemens.
• for 2003 Infiniti Q45, M45 and probably some other models with NATS5 - 5 chars crypted code 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.
