System Description=NJEL0407NATS (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 for Europe).
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.
