SYSTEM DESCRIPTION
• The NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] prevents the engine from being
started by Intelligent Key whose ID is not registered to the vehicle (BCM). It has higher protection against
auto theft involving the duplication of mechanical keys.
• The ignition key integrated in the Intelligent Key c annot start the engine. When the Intelligent Key battery is
discharged, the NVIS (NATS) ID verification is per formed between the transponder integrated with Intelligent
Key and BCM via NATS antenna amp. when the Intelligent Key backside is contacted to push-button ignition
switch. If the verification results are OK, the engine start operation can be performed by the push-button igni-
tion switch operation.
• Locate the security indicator lamp and apply the anti-t heft system equipment sticker that warns that the NVIS
(NATS) is on-board the model.
• Security indicator lamp always blinks when the pow er supply position is any position other than ON.
• Up to 4 Intelligent Keys can be registered (includi ng the standard ignition key) upon request from the owner.
• Specified registration is required when replacing ECM, BCM or Intelligent Key.
• Possible symptom of NVIS (NATS) malfunction is “Engine cannot start”. The engine can not be started
because of other than NVIS (NATS) malfunction, so start the trouble diagnosis according to SEC-63, "Work
Flow".
• If ECM other than genuine part is installed, the engi ne cannot be started. For ECM replacement procedure,
refer to EC-540, "Removal and Installation"
(with QR25DE) EC-997, "Removal and Installation" (with
VQ35DE).

to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
