B2630, B2631 SUNLOAD SENSOR
DescriptionINFOID:0000000003884756
COMPONENT DESCRIPTION
Sunload Sensor
 The sunload sensor (1) is located on the driver’s side speaker
grille.
 It detects sunload entering through windshield by means of a
photo diode. The sensor converts the sunload into a current value
which is then input into the A/C auto amp.
Sunload Sensor Circuit
SUNLOAD INPUT PROCESS
The A/C auto amp. also equips a processing circuit which averages the variations in detected sunload over a
period of time. This prevents drastic swings in the air temperature control system operation due to small or
quick variations in detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor varies whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the air temperature control system operation. On the
other hand, shortly after entering a long tunnel, the system recognizes the change in sunload, and the system
reacts accordingly.

DTC DETECTION LOGIC
NOTE:
 If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to HAC-
164, "DTC Logic" or HAC-165, "DTC Logic".
 Sunload sensor may register a malfunction when indoors, at dusk, or at other times when light is insufficient.
When performing the diagnosis indoors, light the sunload sensor with a lamp (60 W or more).

SQUEAK AND RATTLE TROUBLE DIAGNOSES
SEATS
When isolating seat noise it is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

GENERAL MAINTENANCE
General MaintenanceINFOID:0000000003858221
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 the
checks and inspections themselves or they can have their NISSAN dealers do them for a nominal charge.
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.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the engine oil or refuel.
Item Reference page
TiresCheck the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors and the engine hood operate properly. 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 for lu-
brication frequently.MA-42
Tire rotationTires should be rotated every 10,000 km (6,000 miles).WT-3
Wheel alignment and
balanceIf the vehicle should pull 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
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed.
Item Reference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and oth-
er lamps are all operating properly and installed securely. Also check headlamp
aim.—
Warning lamps and
chimesMake sure that all warning lamps and chimes are operating properly. —
Steering wheelCheck that it has the specified play.
Check for changes in the steering condition, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
Seat beltsCheck 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-42
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.MA-13
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the en-
gine.LU-7
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir.MA-37
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN” lines. —
