Operation Description
• When rear window defogger switch is turned ON while ignition switch is ON, the front air control (rear win-dow defogger switch) transmits rear window defogger switch signal to BCM.
• BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
• Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and operate when rear window defogger relay turns ON.
• Rear window defogger ON is displayed when front air control receives signals.
Timer function
• BCM turns rear window defogger relay ON for appr oximately 15 minutes when rear window defogger switch
is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.
• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.

G. View from rear of vehicle H. View with rear seat cushion removed I. View with center console removed
No. Component Function
1. Combination meter Combination meter transmits the vehicle speed sig-
nal to BCM via CAN communication.
BCM also receives the vehicle speed signal from
ABS actuator and electric uni
t (control unit) via CAN
communication. BCM compares both signals to de-
tect the vehicle speed.
Security indicator lamp is located on combination
meter.
Security indicator lamp blinks when ignition switch
is in any position other than ON to warn that NIS-
SAN VEHICLE IMMOBILIZER SYSTEM-NATS
[NVIS (NATS)] is on board.
Refer to MWI-59, "
METER SYSTEM : Combination
Meter".
2. Push-button ignition switch Push-button ignition switch has push switch inside
which detects that push-button ignition switch is
pressed, and then transmits ON/OFF signal to
BCM. BCM changes the ignition switch position with
the operation of push-button ignition switch. BCM
maintains the ignition switch position status while
push-button ignition switch is not operated.
3. BCM BCM controls INTELLIGENT KEY SYSTEM (EN-
GINE START FUNCTION), NISSAN VEHICLE IM-
MOBILIZER SYSTEM-NATS [NVIS (NATS)] and
VEHICLE SECURITY SYSTEM.
BCM performs the ID verification between BCM and
Intelligent Key when the Intelligent Key is carried
into the detection area of inside key antenna, and
push-button ignition switch is pressed. If the ID ver-
ification result is OK, ignition switch operation is
available.
Then, when the ignition switch is turned ON, BCM
performs ID verification between BCM and ECM. If
the ID verification result is OK, ECM can start en-
gine.
Refer to BCS-6, "
BODY CONTROL SYSTEM :
Component Parts Location" for detailed installation
location.
4. Main power window and door lock/unlock switch Door lock and unlock switch is integrated into the
main power window and door lock/unlock switch.
Door lock and unlock switch transmits door lock/un-
lock operation signal to BCM.
Refer to PWC-7, "
Main Power Window And Door
Lock/Unlock Switch".
5. Front door lock assembly LH Door key cylinder switch is integrated into front door
lock assembly (driver side).
Door key cylinder switch detects door LOCK/UN-
LOCK operation using mechanical key, and then
transmits the operation signal to BCM.
Refer to DLK-17, "
INTELLIGENT KEY SYSTEM :
Front Door Lock Asse
mbly (Driver Side)".
6. Rear door lock actuator LH Rear door lock actuator locks/unlocks the rear door
latch assembly.

DOOR LOCK FUNCTION
• The door lock and unlock switch LH is built into the main power window and door lock/unlock switch.
• The door lock and unlock switch RH is built into
the power window and door lock/unlock switch RH.
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are
unlocked.
Door Key Cylinder
• With the door key inserted in the door key cylinder on driver side, turning it to “LOCK”, will lock door lock actuator of all doors.
• With the door key inserted in the door key cylinder on driver side, turning it to “UNLOCK” onc\
e unlocks the driver side door lock actuator; turning it to “UNLOCK” again within 60 seconds after the first unlock operation
unlocks all of the other doors. - (SELECTIVE UNLOCK OPERATION)
Selective unlock operation mode can be changed using “A UTO LOCK SET” in “Work support”. Refer to BCS-
18, "DOOR LOCK : CONSULT Function (BCM - DOOR LOCK)".
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The automatic door locks function is the function that locks all doors linked with the vehicle speed or shift posi-
tion.
Vehicle Speed Sensing Auto Door Lock*1
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 24 km/h (15 MPH) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door
lock operation has taken place, the BCM will relock al l doors when the vehicle speed reaches 24 km/h (15
MPH) or more again.
