System DescriptionEIS00DAP
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
lSince only NATS ignition keys, whose ID No. s have been registered into the ECM and IMMU of NATS,
allow the engine to run, a vehicle operation without a registered key in NATS 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.
lThis version of NATS has dongle unit to improve its anti-theft performance (RHD models). Dongle unit has
its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization must be per-
formed.
lWhen malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
–When dongle unit has a malfunction and the indicator lamp is illuminated, engine cannot be started. How-
ever engine can be started only one time when security indicator lamp turns off in about 15 minutes after
ignition switch is turned to ON.
lAll of the originally supplied ignition key IDs have been NATS registered in NATS.
If the vehicle owner requests, a maximum of four key IDs can be registered into the NATS components.
lThe security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NATS
warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen NATS detects malfunction, the security indicator lamp lights up as follows.
lNATS trouble diagnoses, system initialization and additional registration of other NATS ignition key IDs
must be performed 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.
lWhen 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 identi-
fication. Therefore, be sure to receive ALL KEYS from vehicle owner.

NATS(NISSAN ANTI-THEFT SYSTEM)
System Composition
EIS00DAQ
The immobilizer function of the NATS consists of the following:
lNATS ignition key
lMechanical key (with Intelligent Key system)
lNATS antenna amp. located in the ignition key cylinder
lBCM
lEngine control module (ECM)
lDongle unit (RHD models)
lSecurity indicator
NOTE:
The communication between ECM, BCM and/or Intelligent Key unit uses the CAN communication sys-
tem.
ECM Re-communicating FunctionEIS00DAR
Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent
Key unit, but only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:
lWhen registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS.
lIf multiple keys are attached to the key holder, separate them before work.
lDistinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Usingaregisteredkey(*2),turnignitionswitchto“ON”.
*2: To perform this step, use the key (except for card plate key) that has been used before performing
ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS and initialize control unit.
