TURN SIGNAL AND HAZARD WARNING LAMPSPFP:26120
Component Parts and Harness Connector LocationNKS004Y3
System DescriptionNKS004Y4
TURN SIGNAL OPERATION
When the ignition switch is in ON or START position, power is supplied
through 10A fuse [No.1, located in fuse block (J/B)]
to BCM (body control module) terminal 38,
through 10A fuse [No.12, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 22,
through 10A fuse [No.14, located in fuse block (J/B)]
to combination meter terminal 23.
Ground is supplied
to BCM terminal 52
to unified meter and A/C amp. terminals 29 and 30, and
to combination meter terminals 10, 11 and 12
through grounds M30 and M66.
LH Turn Signal Lamp
When the turn signal switch is moved to the left position, the BCM receives left turn signal by combination
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ). Power is sup-
plied
through BCM terminal 45
to front combination lamp LH terminal 2

Revision: 2006 November2007 350Z
to rear combination lamp LH terminal 2.
Ground is supplied
to front combination lamp LH terminal 8
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),
to rear combination lamp LH terminal 4
through grounds B5, B6, D105 and T14 (Coupe models)
through grounds B5, B6 and T14 (Roadster models).
The BCM also supplies ground to unified meter and A/C amp. terminals 1and 11 through the CAN communica-
tion lines. This input signal is processed by the unified meter control unit in the combination meter through uni-
fied meter and A/C amp., which in turn supplies ground to left turn signal indicator lamp.
With the power and ground supplied, BCM controls the flashing of LH turn signal lamps.
RH Turn Signal Lamp
When the turn signal switch is moved to the right position, the BCM receives right turn signal by combination
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ). Power is sup-
plied
through BCM terminal 46
to front combination lamp RH terminal 2
to rear combination lamp RH terminal 2.
Ground is supplied
to front combination lamp RH terminal 8
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),
to rear combination lamp RH terminal 4
through grounds B5, B6, D105 and T14 (Coupe models)
through grounds B5, B6 and T14 (Roadster models).
The BCM also supplies ground to unified meter and A/C amp. terminals 1 and 11 through CAN communication
lines. This input signal is processed by unified meter control unit in combination meter through unified meter
and A/C amp., which in turn supplies ground to the right turn signal indicator lamp.
With power and ground supplied, BCM controls the flashing of RH turn signal lamps.
HAZARD WARNING LAMP OPERATION
Power is supplied at all times
through 40A fusible link (letter F, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 10A fuse [No. 18, located in fuse block (J/B)]
to BCM terminal 42,
through 10A fuse [No. 19, located in fuse block (J/B)]
to combination meter terminal 24, and
to unified meter and A/C amp. terminal 21.
Ground is supplied
to BCM terminals 52
to unified meter and A/C amp. terminals 29 and 30, and
to combination meter terminals 10, 11 and 12
through grounds M30 and M66.
When the hazard switch is depressed, power is supplied
through BCM terminal 29
to hazard lamp switch terminal 2.
Ground is supplied
through hazard lamp switch terminal 1
to grounds M30 and M66.

The BCM then supplies power
through BCM terminal 45
to front combination lamp LH terminal 2
to rear combination lamp LH terminal 2,
through BCM terminal 46
to front combination lamp RH terminal 2
to rear combination lamp RH terminal 2.
Ground is supplied
to front combination lamp LH terminal 8, and
to front combination lamp RH terminal 8
through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)
through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),
to rear combination lamp LH terminal 4, and
to rear combination lamp RH terminal 4
through grounds B5, B6, D105 and T14 (Coupe models)
through grounds B5, B6 and T14 (Roadster models).
The BCM also supplies input to unified meter and A/C amp. terminals 1 and 11 through the CAN communica-
tion lines. This input signal is processed by the unified meter control unit in the combination meter through the
unified meter and A/C amp., which in turn supplies ground to the left and right turn signal indicator lamps.
With the power and ground supplied, BCM controls the flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
CAN Communication System DescriptionNKS004Y5
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS004Y6
Refer to LAN-48, "CAN System Specification Chart" .
