Component Parts and Harness Connector LocationINFOID:0000000001704447
System DescriptionINFOID:0000000001704448
The control of the parking, license plate and tail lamp operation is dependent upon the position of lighting
switch. When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input
signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized,
directs power to parking, license plate and tail lamps, which then illuminate.
Power is supplied at all times
• to ignition relay located in IPDM E/R,
• to tail lamp relay located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to the CPU located in the IPDM E/R,
• through 40A fusible link (letter g , located in fuse and fusible link block)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)],
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38,
• to ignition relay located in IPDM E/R and
• through the ignition relay
• to the CPU of the IPDM E/R.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M20 and M61,
• to IPDM E/R terminals 59 and 39
• through grounds E15 and E24.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives an input signal requesting parking,
license plate and tail lamps to illuminate. This input signal is communicated to the IPDM E/R via the CAN com-
munication lines. The CPU, located in the IPDM E/R, controls the tail lamp relay coil. When energized, the tail
lamp relay directs power
• through 10A fuse (No. 37, located in IPDM E/R),
• through IPDM E/R terminal 26
• to front combination lamp LH terminal 6, and
• through IPDM E/R terminal 27

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "System Description" .
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, the battery saver control feature is activated.
Under this condition, the parking, license and tail lamps remain illuminated for 5 minutes, then the parking,
license plate and tail lamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001790697
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Liquid GasketINFOID:0000000001702514
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
• Remove liquid gasket completely from the liquid gasket application surface, bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the Tool.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-42
.
• Within 5 minutes of liquid gasket application, install the mating
component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten bolts or nuts after the installation.
• Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.Tool number :WS39930000 ( — )
