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.

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.

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.
