DESCRIPTION
NOTE:
If customer reports a “No start” condition, request ALL KEYS to be brought to a Nissan dealer in case
of a NATS malfunction.
NATS (Nissan Anti-Theft System) has the following functions:
• NATS shows a higher anti-theft performance at preventing engine to be started by an unregistered key. (reg- istered key: mechanical key and Intelligent Key).
• Only a key with key ID registered in BCM and ECM c an start engine, it has a higher protection against auto
theft that duplicates keys.
• If a malfunction has been detected, security indicator will illuminate when ignition switch is in ON position.
• If the owner requires, mechanical key can be registered for up to 5 keys.
• During trouble diagnosis or when the following parts have been replaced, and if mechanical key is added,
registration* is required.
*: All mechanical keys of the vehicle should be registered.

- Mechanical key
• NATS trouble diagnoses, system initialization and additional registration of other NATS mechanical key IDs
must be carried out using CONSULT-III hardware and CONSULT-III NATS software. When NATS initializa-
tion has been completed, the ID of the inserted mechanical key can be displayed.
Regarding the procedures of NATS initialization and mechanical key ID registration, refer to CONSULT-III
operation manual NATS.
SECURITY INDICATOR
• Forewarns that the vehicle is equipped with NATS.
• Security indicator will not blink while the ignition knob is in ON or START state. NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Secu rity Indicator
• When operating the ignition switch with Intelligent Key, security indicator lamp will turn off at once if ignition
switch is pressed and blinks when ignition switch is released.
• When operating the ignition switch with mechanical key security indicator will turn off at once if mechanical key is inserted into key cylinder and blinks when mechanical key is removed.
(Once the mechanical key is inserted into key cylinder, BCM will only perform the key ID verification with
mechanical key)
System CompositionINFOID:0000000005396704
The function of the NATS consists of the following:
• Mechanical key
• NATS antenna amp. located in the ignition key cylinder
•BCM
• ECM (Engine control module)
• Security indicator
• Intelligent Key unit (if equipped)
NOTE:
The communication between ECM, BCM and/or Intelligent K ey unit uses the CAN communication sys-
tem.
ECM Re-communicating FunctionINFOID:0000000005396705
Performing the following procedure can automatically perform re-communication of ECM and BCM or Intelli-
gent Key unit, but only when the ECM has been replaced with a new one which has never been energized on-
board.
(In this step, initialization procedur e by CONSULT-III is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-III
Operation Manual NATS.

NATS (NISSAN ANTI-THEFT SYSTEM)
•If multiple keys are attached to the key holder, separate them before work.
• Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Use a registered key (*), turn ignition switch to “ON”. *: To perform this step, use the key that has been used before to perform 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-III Operation Manual NATS and initialize control unit.

CONSULT-III DIAGNOSTIC TEST MODE FUNCTION
*: When replace ECM, refer to BL-249, "ECM Re-communicating Function" .
NOTE:
• When any initialization is performed, all ID previ ously registered will be erased and all NATS mechanical
keys must be registered again.
• The engine cannot be started with an unregistered key. In this case, the system will show “DIFFERENCE OF
KEY” or “LOCK MODE” as a self-diagnos tic result on the CONSULT-III screen.
• In rare case, “CHAIN OF ECM-IMMU” might be stored as a self-diagnostic result during key registration pro-
cedure, even if the system is not malfunctioning.
