NATS lesson 101

NATS = nissan anti theft is pretty much a foolproof system that w/o expensive reprogramming stuff you just can't get rid of

NATS started in the US in 1999 as V 3.0... consisted of a NATS box which had a programmable portion and the ECU which had to be programmed with the same number.. which comes off of the key.. which a small FM trasmitter reads on your column.
Programmable only with a Consult 2 or 3 which we have.

2002.5+ was V 5.0 NATS which has a programmable BCM , ECU portion that has to match the key in the same fashion as the old NATS... but the BCM serial number has to be entered into a special Nissan cypher key program that gives you a modifier number that needs to be entered into the programming unit like consult 2 or 3.... its a double proof system.

or we just bypass everything by killing NATS and all of the millions of other codes the ECU tries to throw at you by not seeing the BCM , IPDM, VSS, ABS, ABCDEFG solenoid...

You get happy VQ revving on the ground not throwing any codes..
