Component Function
CVT shift selector (detention
switch)
(CVT models)
Detention switch is integrated into CVT shift sector, and detects that selector lever is locked
in the P position, then transmits ON/OFF signal to BCM and IPDM E/R.
Refer to
TM-436, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
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 Anti-Theft System (NATS) is on board.
Stop lamp switch
Stop lamp switch detects that brake pedal is depressed, and then transmits ON/OFF signal
to BCM.
Refer to
ECH-13, "Component Parts Location"
for detailed installation location.
Clutch interlock switch
(M/T models)
Clutch interlock switch detects that clutch pedal is depressed and transmits ON/OFF signal
to BCM.
Clutch pedal position switch detects that clutch pedal is depressed, and then transmits ON/
OFF signal to BCM and IPDM E/R.
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.
TCM (CVT models)
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 transmission range switch
• P position signal from IPDM E/R (CAN)
• Neutral 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 transmission range switch
• P/N position signal from BCM (CAN)
Refer to
TM-436, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
Transmission range switch
(CVT models)
Transmission range switch detects the selector lever position, and then transmits the P/N po-
sition signal to BCM and IPDM E/R.
BCM confirms the CVT shift selector position with the following 5 signals.
• P position signal from CVT shift selector (detention switch)
• P/N position signal from transmission range switch
• P position signal from IPDM E/R (CAN)
• Neutral position signal from IPDM E/R (CAN)
• P/N position signal from TCM (CAN)
IPDM E/R confirms the CVT shift selector position with the following 3 signals.
• P position signal from CVT shift selector (detention switch)
• P/N position signal from transmission range switch
• P/N position signal from BCM (CAN)
Refer to
TM-436, "CVT CONTROL SYSTEM : Component Parts Location"
for detailed instal-
lation location.
Reverse/neutral position
switch
(M/T models)
Reverse/neutral position switch detects that shift lever is in the neutral position, and then
transmits ON/OFF signal to BCM.
Refer to
TM-80, "PARK/NEUTRAL POSITION (PNP) SWITCH : Component Parts Location"
for detailed installation location.
Hood switch
Refer to
SEC-13, "Hood Switch"
.
Horn
Horn operate for warning vehicle surroundings when VEHICLE SECURITY SYSTEM oper-
ates.
