ILLUMINATION
Revision: 2006 November2007 350Z
ILLUMINATIONPFP:27545
System DescriptionNKS004ZY
Control of the illumination lamp operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position, the BCM (body control module)
receives input signal requesting illumination lamps to illuminate. This input signal is communicated to the
IPDM E/R (intelligent power distribution module engine room) through the CAN communication lines. The
CPU (central processing unit) located in the IPDM E/R controls tail lamp relay coil. This relay, when energized,
directs power to illumination lamps, which then illuminate.
OUT LINE
Power is supplied at all times
through 10A fuse (No.71, located in IPDM E/R)
to tail lamp relay, located in IPDM E/R, and
to CPU located in IPDM E/R,
through 15A fuse (No.78, located in IPDM E/R)
to CPU located in IPDM E/R.
Power is also supplied at all times
through 40A fusible link (letter F, located in fuse, fusible link and relay box)

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position, and the ignition switch is turned
from ON or ACC to OFF, battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position after illumination lamps are turned off by
battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
CAN Communication System DescriptionNKS004ZZ
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 UnitNKS00500
