HEADLAMP (FOR CANADA) - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00ICD
System DescriptionEKS00ICE
Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination
switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input sig-
nal requesting the headlamps (and tail lamps) illuminate. The request is then communicated to the IPDM E/R
(intelligent power distribution module engine room) via the CAN communication lines. The CPU (central pro-
cessing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils.
These relays direct power to the respective headlamps, which then illuminate. When the headlamp switch is
OFF or in the 1ST position (parking lamps ON), the parking brake is released and the engine is running, the
IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light relay 1 to actuate the
daytime light function.

to front combination lamp RH terminal 2 via

daytime light relay 1 terminals 3 and 4

through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power

from daytime light relay 1 terminal 3

to front combination lamp RH terminal 2,

through front combination lamp RH high beam terminal 1

to IPDM E/R terminal 56,

through 10A fuse (No. 34, located in IPDM E/R) and

through both de-energized headlamp high relays

to 10A fuse (No. 35, located in IPDM E/R),

through IPDM E/R terminal 55

to front combination lamp LH terminal high beam 1.
Ground is supplied

to front combination lamp LH terminal 2

through grounds E15 and E24,

to daytime light relay 1 terminal 1

through IPDM E/R terminal 6.
With power and ground supplied, high beam headlamps illuminate at reduced intensity.

ENGINE OIL LEVEL
NOTE:
Before starting engine, park vehicle on a level surface and check the engine oil level. If engine is already
started, stop it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range (A) as shown.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:

Oil pan (upper and lower)

Oil pan drain plug

Oil pressure switch

Oil filter

Intake valve timing control solenoid valve

Front cover

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)

Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WA RN ING:

Be careful not to burn yourself, as engine oil may be hot.

For engine oil pressure check the transaxle should be in “ Park position” (A/T models) and (CVT
models) or “Neutral position” (M/T models), and apply the parking brake securely.
1. Disconnect harness connector at oil pressure switch (1), and
remove oil pressure switch using a suitable tool.

GENERAL MAINTENANCE
Revision: June 20062007 Versa
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).Accelerator pedalCheck the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.—
Clutch pedalMake sure the pedal operates smoothly and check that it has the proper free
play.MA-22
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep floor mats away from the pedal.BR-6, "
Inspection and
Adjustment" and BR-19,
"On-board Inspection"
Parking brakeCheck that the lever has the proper travel and make sure that the vehicle is held
securely on a fairly steep hill when only the parking brake is applied.PB-4, "INSPECTION"
Automatic transaxle
“Park” mechanismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the “P” position without applying any brakes.—
CVT P (Park) position
mechanismOn a fairly steep hill check that the vehicle is held securely with the selector
lever in the “P” position without applying any brakes.— ItemReference page
ItemReference page
Windshield
washer fluidCheck that there is adequate fluid in the tank. —
Engine coolant
levelCheck the coolant level when the engine is cold.CO-8, "
LEVEL CHECK"
A/C condenser,
radiator and
hosesCheck the front of the condenser and radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated. Make sure the radiator hoses have no
cracks, deformation, deterioration or loose connections.—
Brake and clutch
fluid levelsMake sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoirs.BR-9, "
CHECKING BRAKE
FLUID LEVEL" and MA-22,
"Checking Clutch Fluid
Level and Leaks"
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require fre-
quent checks of the battery fluid level.—
Engine drive beltsMake sure that no belt is frayed, worn, cracked or oily.MA-13
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turning
off the engine.LU-5, "ENGINE OIL
LEVEL"
Automatic tran-
saxle fluid levelCheck the level on the dipstick after putting the selector lever in “P” with the
engine idling.MA-20 and MA-22
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.MA-20
UnderbodyThe underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances,
otherwise rust will form on the floor pan, frame, fuel lines and around the exhaust
system. At the end of winter, the underbody should be thoroughly flushed with
plain water, being careful to clean those areas where mud and dirt can easily
accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is nor-
mal. If you should notice any leaks or gasoline fumes are evident, check for the
cause and correct it immediately.—
