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 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.

System DescriptionNKS004Z0
Control of parking, license plate, side maker and tail lamps operation is dependent upon the position of lighting
switch (combination switch). When the lighting switch is in the 1ST position, the BCM (body control module)
receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input
signal is communicated to the IPDM E/R (intelligent power distribution module engine room) through CAN
communication. The CPU (central processing unit) located in the IPDM E/R controls the tail lamp relay coil
and daytime light relay
* coil. These relay, when energized, directs power to parking, license plate, side marker
and tail lamps, which then illuminate.
NOTE:
Daytime light relay*: Canada models

OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives input signal requesting the parking,
license plate, side marker and tail lamps to illuminate. This input is communicated to the IPDM E/R through
the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil and daytime
light relay
* coil. These relay, when energized, directs power to parking, license plate, side marker and tail
lamps, which when energized, directs power

through IPDM E/R terminal 22 (USA models)

through daytime light relay terminal 5 (Canada models)

to front combination lamp LH terminals 6

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the parking, license, side marker and tail lamps remain illuminated for 5 minutes, then the
headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
