Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it without
the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.
The NATS security indicator is located on the instrument panel. The
indicator blinks when the ignition switch is in ªOFFº or ªACCº posi-
tion. Therefore, NATS warns outsiders that the vehicle is equipped
with the anti-theft system.
IWhen NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
IIf the malfunction indicator lamp comes on while the engine is
running, return the vehicle to the workshop before turning the
ignition switch ªOFFº.
Once the ignition switch is turned ªOFFº, the engine can not be
started.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs) CON-
SULT-II hardware and CONSULT-II NATS software is neces-
sary.
Regarding the procedures of NATS initialization and NATS igni-
tion key ID registration, refer to CONSULT-II operation manual,
NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner.
A maximum of five key IDs can be registered into NATS.
IWhen failing to start the engine first-time using the key of
NATS, starts as follows:
(1) Turn ignition key to ªOFFº.
(2) Wait approx. 5 seconds.
(3) Turn ignition key to ªSTARTº again while keeping the key
apart from any others on key-chain.
