ILLUMINATION
Revision: 2007 April2007 M35/M45
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil,
which, when energized, directs power

EXTERIOR LAMP BATTERY SAVER CONTROL
BCM activates the exterior lamp battery saver control function and turns off the exterior lamps to prevent bat-
tery from over discharge when the combination switch (lighting switch) is in 1ST or 2ND position and/or the
front fog lamp switch ON and the door lock operation is performed by keyless entry system.
CAN Communication System DescriptionNKS003TI
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 UnitNKS003TJ

(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.
CHASSIS AND BODY MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary.
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.MAINTENANCE OPERATIONMAINTENANCE INTERVAL

CLIMATE CONTROLLED SEATPFP:870U6
Component Parts and Harness Connector LocationNIS0027H
System DescriptionNIS0027I
The climate controlled seat system is controlled by climate controlled seat control unit.
Heating and cooling are possible for a thermal electric device (heat conversion machine).
NOTE:

The climate controlled seat system is downed when the temperature sensor set as the seat cushion and
the seat back's thermal electric device machine detects 20 °C (68 °F)or more of mutual differences of tem-
perature.

In this case, by turning off ignition switch, system down is canceled and it can be reused by turning on
ignition switch again.

The climate controlled seat blower keep low speed for approximately 60 seconds after turning the climate
controlled seat switch.
CAUTION:

The thermal electric device has the character in which, as for an opposite side. one side becomes
high temperature at the time of low temperature.

At the time of work, please turn OFF a switch, and carry it out after checking that the thermal elec-
tric device has got cold.
Power is at all times supplied

through 15A fuse [No. 41 located in the fuse fusible link and relay unit]

to climate controlled seat relay terminals 5.

through 15A fuse [No. 42 located in the fuse fusible link and relay unit]

to climate controlled seat relay terminals 7.
When the ignition switch turned to ON or START position,
Power is supplied

through 10A fuse [No. 12, located in the fuse block (J/B)]

to climate controlled seat relay terminal 2.
Then ground is supplied

to climate controlled seat relay terminal 1,

through body grounds E22 and E43.
Then climate controlled seat relay is energized.
When climate controlled seat relay is turned to ON,
Power is supplied,

through climate controlled seat relay terminal 3,

to climate controlled seat control unit (passenger side) terminal 2 and 4.

through climate controlled seat relay terminal 6,

to climate controlled seat control unit (driver side) terminal 2 and 4.
When climate controlled switch select HEAT, ground is supplied

through climate controlled seat switch terminal 1 and 3,

to climate controlled seat control unit terminal 10.
Then, the climate controlled seat control unit receives climate controlled seat switch HEAT signal.
When climate controlled seat switch select COOL, ground is supplied

through climate controlled seat switch terminal 1 and 2,

to climate controlled seat control unit terminal 20,
Then, the climate controlled seat control unit receives climate controlled switch COOL signal.
When blower motor rotates, signal is transmitted

to climate controlled seat control unit terminal 18,

through climate controlled seat blower motor terminal 1.
This is climate controlled seat blower motor tachometer signal.
When climate controlled seat control unit receives climate controlled seat switch signal and tachometer signal,
Power is supplied

to climate controlled seat blower motor terminal 4,

through climate controlled seat control unit terminal 17.
This is blower motor revolution control signal.
When blower motor receivers blower motor revolution control signal,
Power is supplied

through climate controlled seat control unit terminal 14,

to climate controlled seat blower motor terminal 2.
When number of rotations correspond signal,
Ground is supplied

to climate controlled seat blower motor terminal 3,

through climate controlled seat control unit terminal 7,

through climate controlled seat control unit terminal 3,

through body grounds B5, B40 and B131.
Then motor revolution is controlled.
When the ignition switch turned to ON or START position,
Power is supplied
