SYSTEM DESCRIPTION

NATS (Nissan Anti-Theft System) has the following immobilizer functions:
• Engine immobilizer shows high anti-theft performance to prevent engine from starting by other than the

owner.

• Only a key with key ID registered in BCM and ECM can start engine, and shows high anti-theft performance

to prevent key from being copied or stolen.

• Security indicator always flashes with mechanical key removed condition (key switch: OFF) and ignition

knob released condition on LOCK position (ignition knob switch: OFF).

• Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system. Refer to

SEC-19,

"System Description"

.

• If system detects malfunction, security indicator illuminates when ignition switch is turned to ON position.
• If the owner requires, ignition key ID or mechanical key ID 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 keys kept by the owner of the vehicle should be registered with mechanical key.

- ECM
- BCM
- Mechanical key
- ABS actuator control unit
- EPS control unit
- IPDM E/R
- Combination meter
• NATS trouble diagnosis, system initialization and additional registration of other mechanical key IDs must be

carried out using CONSULT-III hardware and SECURITY CARD.
When NATS initialization has been completed, the ID of the inserted mechanical key or mechanical key IDs
can be carried out.

• Possible symptom of NATS malfunction is “Engine cannot start”. In J10, the engine can be started with the

Intelligent Key system and NATS. Identify the possible causes according to “Work Flow”, Refer to

SEC-5,

"Work Flow"

.

• If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce-

dure, refer to

SEC-8, "ECM RE-COMMUNICATING FUNCTION : Description"

.

PRECAUTIONS FOR KEY REGISTRATION

• The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.

Therefore the registered Intelligent Key is necessary for this procedure. Before starting the registration oper-
ation collect all registered Intelligent Keys from the customer.

• The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in

mechanical key) to BCM.
The Intelligent Key ID registration is the procedure that registers the ID to Intelligent Key unit.

• When performing the Intelligent Key system registration only, the engine cannot be started by inserting the

key into the key cylinder. When performing the NATS registration only, the engine cannot be started by using
the mechanical key.

SECURITY INDICATOR

• Always flashes with ignition knob released (ignition knob switch: OFF) condition on ignition knob LOCK posi-

tion.

• Always flashes with ignition knob released (ignition knob switch: OFF) condition on mechanical key removed

position.

MAINTENANCE INFORMATION

It is necessary to perform NATS ID registration when replacing any of the following part.
If it's not (or fail to do so), the electrical system may not operate properly.
*: New one means a virgin control unit that has never been energized on-board.
• ABS actuator control unit
• EPS control unit
