ILLUMINATION
Revision: June 20062007 Versa
ILLUMINATIONPFP:27545
System DescriptionEKS00HZU
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the illu-
mination 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 CPU located in IPDM E/R,

through 40A fusible link (letter g , located in fuse and fusible link box)

to BCM terminal 70, and

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

to ignition relay, located in IPDM E/R, and

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 38.
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 M57 and M61, and

to IPDM E/R terminals 39 and 59

through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicated to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power

through 10A fuse (No. 37, located in IPDM E/R)

through IPDM E/R terminal 29

to microphone terminal 3 (with Bluetooth)

to illumination control switch terminal 1

to glove box lamp terminal 1 (with glovebox lamp)

to audio unit terminal 9

to front air control terminal 5

to A/T device terminal 3 (without M/T)

to hazard switch terminal 3

to combination meter terminal 12

to door mirror remote control switch terminal 16, and

to main power window and door lock/unlock switch terminal 4.
Ground is supplied

GENERAL MAINTENANCEPFP:00000
Explanation of General MaintenanceELS001YB
General MaintenanceELS001YC
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or they can have their NISSAN dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.ItemReference page
TiresCheck the pressure including the spare, at least once a month and always prior
to a long distance trip. Adjust to the specified pressure if necessary. Check care-
fully for damage, cuts or excessive wear.WT-29, "
Tire"
Wheel nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.WT-6, "Rotation"
WindshieldClean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary.—
Tire rotationTires should be rotated every 12,000 km (7,500 miles).WT-6, "
Rotation"
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed.FSU-6, "Wheel Align-
ment Inspection" and
WT-6, "
Balancing
Wheels"
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly. —
Doors and engine
hoodCheck that all doors and the engine hood operate smoothly as well as the trunk
lid and back hatch. Also make sure that all latches lock securely. Lubricate if
necessary. Make sure that the secondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.MA-27, "
Lubricating
Locks, Hinges and Hood
Latch"
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis.—
ItemReference page
Warning lamps and
buzzers/chimesMake sure that all warning lamps and buzzers/chimes are operating properly. —
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioning.—
Steering wheelCheck that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
SeatsCheck seat position controls such as seat adjusters, seat back recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restraints move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seat backs.—
Seat belts
Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.MA-27, "
