System DescriptionNIS0003C
NVIS (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:

Since only NVIS (NATS) ignition keys, whose ID Nos. have been registered into the ECM and BCM, allow
the engine to run, a vehicle operation without a key registered in NVIS (NATS) is prevented by NVIS
(NATS).
That is to say, NVIS (NATS) will immobilize the engine if someone tries to start it without the registered
key of NVIS (NATS).

All of the originally supplied ignition key IDs (except for card plate key) have been registered in NVIS
(NATS).
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS)
components.

The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NVIS
(NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the “ON”
position.

NVIS (NATS) trouble diagnoses, system initialization and additional registration of other NVIS (NATS)
ignition key IDs must be carried out using CONSULT-III hardware and CONSULT-III NVIS (NATS) soft-
ware.
When NVIS (NATS) initialization has been completed, the ID of the inserted ignition key is automatically
registered in NVIS (NATS). Then, if necessary, additional registration of other NVIS (NATS) ignition key
IDs can be carried out.
Regarding the procedures of NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer
to CONSULT-III Operation Manual NATS-IVIS/NVIS.

When servicing a malfunction of the NVIS (NATS) (indicated by lighting up of Security Indicator
Lamp) or registering another NVIS (NATS) ignition key ID No., it may be necessary to re-register
original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.

Work FlowNIS002B3
1. LISTEN TO CUSTOMER COMPLAINT OR REQUEST
Get symptoms or listen to customer complaints or request.
NOTE:
In case of request for NVIS (NATS) system repair, the key ID re-registration might be necessary. Keep all the
ignition keys before work for the re-registration.
Key ID registration request>>Register ignition key by referring to CONSULT-III Operation Manual NATS-
IVIS/NVIS.
Request for malfunction repair.>>GO TO 2.
2. CONFIRM SELF DIAGNOSIS 1
Start CONSULT-III with ignition switch in ON position and confirm “SELF DIAG RESULT” with “ENGINE”.
Is DTC detected?
No malfunction>>GO TO 3.
If the codes detected are between the interval P1610 to P1615.>> Refer to BL-154, "
NVIS (NATS) SELF-
DIAGNOSTIC RESULTS ITEM CHART" .
If the codes detected are between the interval P1610 to P1615 and others.>> GO TO 4.
3. CHECK SECURITY INDICATOR FUNCTION
Check that security indicator for lighting up fulfill the two conditions below.

Security indicator lights off when ignition switch is ON position.

Security indicator blinks when ignition switch is in any position except ON.
Lighting up condition is normal.>>Inspection END.
Lighting up condition is malfunctioning.>>Perform security indicator Inspection. Refer to BL-163, "
Diagnostic
Procedure 5" .
4. TROUBLE DIAGNOSIS
Perform by priority the trouble diagnosis for the codes which are not included in the interval P1610 to P1615.
Is DTC detected?
No malfunction>>Inspection END.
If the codes detected are between the interval P1610 to P1615.>>BL-154, "
