[WITH INTELLIGENT KEY SYSTEM]

NVIS (NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)

- Mechanical key
- Intelligent Key unit
- Remote keyless entry receiver
- Steering lock solenoid
• NATS trouble diagnosis, system initialization and additional registration of other mechanical key IDs must be

carried out using CONSULT-III.
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”. 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: LOCK) condition on ignition knob LOCK

position.

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

removed position.

MAINTENANCE INFORMATION

CAUTION:

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.

• Intelligent Key unit
• BCM
• ECM
• Mechanical key
• Steering lock solenoid
• NATS antenna amp.
