BODY CONTROL SYSTEM
System DescriptionINFOID:0000000003809584
OUTLINE
 BCM (Body Control Module) controls the various electrical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
 BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power consumption with the ignition switch OFF.
 BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT-III and various set-
tings.

POWER CONSUMPTION CONTROL SYSTEM
Sleep condition
Wake-up operation
 BCM changes from the low power consumption mode to the CAN communication sleep mode when the any
of the BCM wake-up conditions is fulfilled. Only the control with BCM is activated.
 BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions is
fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
 Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com-
bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.

System DiagramINFOID:0000000003814906
System DescriptionINFOID:0000000003814907
 The NVIS (NATS) is an anti-theft system by registering an Intelligent Key ID in to the vehicle and prevents
the engine being started by an unregistered Intelligent Key. It has a higher protection against auto thefts that
duplicate mechanical key.
 It performs the ID verification when starting the engine in the same way as the Intelligent Key system. But, it
performs the NVIS (NATS) ID verification when inserting the Intelligent Key and performs the Intelligent Key
ID verification when carrying the Intelligent Key.
 The mechanical key integrated in the Intelligent Key cannot start the engine. When the Intelligent Key bat-
tery is discharged, the NVIS (NATS) ID verification memorized to the transponder integrated with Intelligent
Key is performed by inserting the Intelligent Key into the key slot. If the verification results are OK, the
engine start operation can be performed by the push-button ignition switch operation.
 Locate the security indicator and apply the anti-theft system equipment sticker, forewarn that the NVIS
(NATS) is onboard with the model.
 The security indicator always blinks when the power supply position is in LOCK, OFF and ACC position.
 Up to 4 Intelligent Keys can be registered (Including the standard ignition key) on request from the owner.
 The specified registration is required when replacing ECM, BCM or Intelligent Key. The registrations proce-
dure for NVIS (NATS) and registration procedure for Intelligent Key when installing the BCM, refer to CON-
SULT-III Operation Manual NATS-IVIS/NVIS.
 Possible symptom of NVIS (NATS) malfunction is “Engine can not start”. The engine can be started with the
Intelligent Key system and NVIS (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 : Special Repair Requirement".
PRECAUTIONS FOR KEY REGISTRATION
 The key registration is a procedure that erases the current NVIS (NATS) ID once, and then re-registers a
new ID operation. Therefore the registered Intelligent Key is necessary for this procedure. Before starting
the registration operation collect all registered Intelligent Keys from the customer.
 When registering the Intelligent Key, performs only one procedure to register simultaneously both IDs (NVIS
“NATS” ID registration and Intelligent Key ID registration).
The NVIS (NATS) ID registration is the procedure that registers the IDs stored into the transponder (inte-
grated in Intelligent Key) to BCM.
The Intelligent Key ID registration is the procedure that registers the ID to BCM.
 When performing the Intelligent Key system registration only, the engine cannot be started by inserting the
key into the key slot. When performing the NVIS (NATS) registration only, the engine cannot be started by
pressing the push-button ignition switch when carrying the Intelligent Key. The registrations of both systems
should be performed.
SECURITY INDICATOR LAMP
 Warns that the vehicle is equipped with NVIS (NATS).
