Key turned to lock position in door Hazard flash once* Key cylinder lock switch signal
Lighting switch turned 1st position or 2nd
position from offHazard flash once Tail lamp signal
Key put in ignition from out Hazard flash once Key in detect signal
Door lock/unlock switch is pressed Hazard flash once Central door lock/unlock signal
*) Hazard may flash a second time because of Driver's door status signal change. The min. delay time between flash actions is 100
ms.
In case the system does not operate as described above, check the concerned circuit for open or short. After
completion, the Diagnostic Mode can be switched off by pressing the rear defogger switch or by turning the
ignition to ªONº. The hazard lamp will flash at 3 Hz for 3 seconds to confirm that Diagnostic Mode has been
switched off.

System DescriptionNLEL0407NATS (Nissan Anti-Theft System) has the following immobilizer functions:
+Since only NATS ignition keys, whose ID nos. have been registered into the ECM and IMMU of NATS,
allow the engine to run, operation of a stolen vehicle without a NATS registered key is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.
+This version of NATS has dongle unit to improve its anti-theft performance (RHD models only). Dongle
unit has its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization must
be carried out.
+When malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
þ When dongle unit has a malfunction and the indicator lamp is illuminated, engine can not be started.
However engine can be started only one time when security indicator lamp turns off in about 15 minutes
after ignition switch is turned to ON.
+All of the originally supplied ignition key IDs have been NATS registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-
nents.
+The security indicator blinks when the ignition switch is in ªOFFº or ªACCº position. Therefore, NATS warns
outsiders that the vehicle is equipped with the anti-theft system.
+When NATS detects trouble, the security indicator lamp lights up as follows.

+NATS trouble diagnoses, system initialization and additional registration of other NATS ignition key IDs
must be carried out using CONSULT-II hardware and CONSULT-II NATS software.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-II
operation manual, NATS.
+When servicing a malfunction of the NATS (indicated by lighting up of Security Indicator Lamp) or
registering another NATS ignition key ID no., it may be necessary to re-register original key iden-
tification. Therefore, be sure to receive ALL KEYS from vehicle owner.

NOTE:
+When any initialization is performed, all ID previously reg-
istered will be erased and all NATS ignition keys must be
registered again.
+The engine cannot be started with an unregistered key. In this
case, the system may show ªDIFFERENCE OF KEYº or
ªLOCK MODEº as a self-diagnostic result on the CONSULT-II
screen.
+When initialization is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recognition
of the dongle unit ID.
+In rare case, ªCHAIN OF ECM-IMMUº might be stored as a
self-diagnostic result during key registration procedure, even if
the system is not malfunctioning.
