General Information for Xenon Headlamp Trouble DiagnosisNKS004XV
In most cases, malfunction of xenon headlamp - “does not illuminate”, “flickers” or “dark” - is caused by a mal-
functioning xenon bulb. A malfunctioning HID control unit or lamp housing, however, may be a cause. Be sure
to perform trouble diagnosis following the steps described below.
Caution:NKS004XW

Installation or removal of connector must be done with lighting switch OFF.

Disconnect the battery cable from the negative terminal or remove power fuse.
CAUTION:
After the battery cables are disconnected, never open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and
the side roof panel may be damaged.

When the lamp is illuminated (when lighting switch is ON), never touch harness, HID control unit, inside of
lamp, or lamp metal parts.

To check illumination, temporarily install lamp in vehicle. Be sure to connect power at vehicle side connec-
tor.

If error can be traced directly to electrical system, first check for items such as blown fuses and fusible
links, broken wires or loose connectors, dislocated terminals, and improper connections.

Never work with wet hands.

Using a tester for HID control unit circuit trouble diagnosis is prohibited.

Disassembling HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.

Immediately after illumination, light intensity and color will fluctuate, but there is nothing wrong.

When bulb has come to end of its life, brightness will drop significantly, it will flash repeatedly, or light color
will turn reddish.When lighting switch is OFF : HEAD LAMP SW1 OFF
: HEAD LAMP SW2 OFF

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
PKIC4853E

TURN SIGNAL AND HAZARD WARNING LAMPS
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 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.

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.
