NATS(Nissan Anti-Theft System)
System Description

NATS V2.0forNissan modelN15hasthefollowing immobiliser functions:
• Since onlyNATS ignition keys,whose IDnos. have been registered intotheECM andIMMU ofNATS,
allow theengine torun, operation ofastolen vehicle withoutaNATS registered keyisprevented by
NATS.
That isto say, NATS V2.0willimmobilize theengine ifsomeone triestostart itwithout theregis-
tered keyofNATS V2.0.
• Both ofthe originally suppliedignitionkeyIDshave been NATS registered.
If requested bythe vehicle owner,amaximum offour keyIDscan beregistered intotheNATS com-
ponents.
• The NATS security indicator (NATSsecurity ind.)blinks whentheignition switchisin "OFF" or
"ACC" position. Therefore, NATSwarns outsiders thatthevehicle isequipped withtheanti-theft
system.
• When NATSdetects trouble, themalfunction indicatorlamp(MIL) blinks.
• NATS trouble diagnoses, systeminitialisation andadditional registration ofother NATS ignition key
IDs must becarried outusing CONSULT hardwareandCONSULT NATSsoftware.
When NATS initialisation hasbeen completed, theIDofthe inserted ignitionkeyisautomatically
NATS registered. Then,ifnecessary, additionalregistration ofother NATS ignition keyIDscan be
carried out.
Regarding theprocedures ofNATS initialisation andNATS ignition keyIDregistration, refertoCON-
SUL Toperation manual,NATSV2.0.
• When diagnosing NATSV2.0using CONSULT, adapterandadapter harness forNATS V1.0arenot
necessary, althoughadirect DDLcable connection betweenCONSULT andDOL connector is
required.
• When servicing amalfunction ofthe NATS V2.0(indicated byflashing ofMalfunction IndicatorLamp)
or registering anotherNATSignition keyIDno., itmay benecessary tore-register originalkeyiden-
tification. Therefore, besure toreceive allkeys from vehicle owner.
