signal from Intelligent Key, and then transmits the signal to BCM.
Refer to
DLK-18, "DOOR LOCK SYSTEM : Component Parts Location"
for detailed installa-
tion location.
3
Inside key antenna (Con-
sole)
Inside key antenna (Console) detects whether Intelligent Key is inside the vehicle or not, and
then transmits the signal to BCM.
Refer to

ABS actuator and electric
unit (control unit)
ABS actuator and electric unit (control unit) transmits the vehicle speed signal to BCM via
CAN communication.
BCM also receives the vehicle speed signal from combination meter via CAN communica-
tion. BCM compares both signals to detect the vehicle speed.
Refer to
BRC-9, "Component Parts Location"
for detailed installation location.
6
Stop lamp relay
Stop lamp relay is used to send the stop lamp switch signal to BCM.
Refer to
TM-10, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
7
TCM
TCM receives the shift position signal from transmission range switch, and then transmits the
P/N position signal to BCM via CAN communication.
BCM confirms the selector lever position with the following 5 signals.
• P position signal from CVT shift selector (detention switch)
• P/N position signal from TCM
• P position signal from IPDM E/R (CAN)
• P/N position signal from IPDM E/R (CAN)
• P/N position signal from TCM (CAN)
IPDM E/R confirms the selector lever position with the following 3 signals.
• P position signal from CVT shift selector (detention switch)
• P/N position signal from TCM
• P/N position signal from BCM (CAN)
Refer to
TM-10, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
8
ECM
ECM controls the engine.
When ignition switch is turned ON, BCM starts communication with ECM and performs the
ID verification between BCM and ECM.
If the verification result is OK, the engine can start. If the verification result is NG, the engine
can not start.
Refer to
EC-15, "ENGINE CONTROL SYSTEM : Component Parts Location"
for detailed in-
stallation location.
9
NATS antenna amp.
Refer to
.
10
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.
11
Stop lamp switch
Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal
to BCM.
Refer to
TM-10, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
12
IPDM E/R
Starter control relay and starter relay are integrated in IPDM E/R and used for the engine
starting function. Starter relay is controlled by BCM, and starter control relay is controlled by
IPDM E/R while communicating with BCM. IPDM E/R sends the starter control relay and
starter relay status signal to BCM.
Refer to
PCS-4, "IPDM E/R : Component Parts Location"
for detailed installation location.
13
BCM
BCM controls INTELLIGENT KEY SYSTEM (ENGINE START FUNCTION), NISSAN VEHI-
CLE IMMOBILIZER 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 verification 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 engine.
Refer to
BCS-4, "BODY CONTROL SYSTEM : Component Parts Location"
for detailed in-
stallation location.
14
Combination meter
Combination meter transmits the vehicle speed signal to BCM via CAN communication.
BCM also receives the vehicle speed signal from ABS actuator and electric unit (control unit)
via CAN communication. BCM compares both signals to detect 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 NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] is on board.
Refer to
MWI-7, "METER SYSTEM : Combination Meter"
.
No.
