System DescriptionNKS002Z2
Control of illumination lamps operation is dependent upon position of lighting switch (combination switch).
When lighting switch is placed in the 1ST or 2ND position (or if auto light system is activated), BCM (body con-
trol module) receives input signal requesting illumination lamps to illuminate. This input signal is communi-
cated to IPDM E/R (intelligent power distribution module engine room) through the CAN communication lines.
The CPU (central processing unit) located in the IPDM E/R controls tail lamp relay coil. This relay, when ener-
gized, directs power to illumination lamps, which then illuminate.
Power is supplied at all times
through 10A fuse (No. 71, located in IPDM E/R)
to tail lamp relay, located in IPDM E/R, and
to CPU located in IPDM E/R.
Power is also supplied at all times
through 50A fusible link (letter M, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 15A fuse [No. 22 located in fuse block (J/B)]
to BCM terminal 42,
through 15A fuse (No. 78, located in IPDM E/R)
to CPU located in IPDM E/R,
through 10A fuse [No. 19 located in fuse block (J/B)]
to unified meter and A/C amp. terminal 21, and
to combination meter terminal 8.
With ignition switch in ON or START position, power is supplied
to ignition relay, located in IPDM E/R, from battery direct,
through 15A fuse [No. 1 located in fuse block (J/B)]
to BCM terminal 38,
through 10A fuse [No. 12, located in fuse block (J/B)]
to unified meter and A/C amp. terminal 22,
to combination meter terminal 7.
With ignition switch in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to combination meter terminal 4 and
to BCM terminal 11.
Ground is supplied
to BCM terminals 49 and 52
to unified meter and A/C amp. terminals 29 and 30, and
to combination meter terminals 5, 6, and 15
through grounds M35, M45, and M85,
to IPDM E/R terminals 38 and 60
through grounds E21, E50, and E51.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal
requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R through the CAN
communication lines. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized,
directs power
through IPDM E/R terminal 22
to glove box lamp terminal 1
to A/T device (illumination) terminal 11
to snow mode switch (illumination) terminal 5
to VDC off switch (illumination) terminal 3

to glove box lamp terminal 2, and
to coin box illumination terminal 3
through grounds M35, M45 and M85,
to rear power window switch LH and RH (illumination) terminals 7
through grounds B15 and B45.
With power and ground supplied, illumination lamps illuminate.
EXTERIOR LAMP BATTERY SAVER CONTROL
When the lighting switch is in the 1ST or 2ND position (or if auto light system is activated), and ignition switch
is turned from ON or ACC to OFF, battery saver control function is activated.
Under this condition, illumination lamps remain illuminated for 5 minutes, then illumination lamps are turned
off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally 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 shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
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 pans (lower and upper)
Oil pan drain plug
Oil pressure switch
Oil filter
Oil filter bracket (AWD models)
Oil cooler
Water pump cover
Chain tensioner cover
Intake valve timing control cover and intake valve timing control solenoid valve
Mating surface between cylinder head and rocker cover
Mating surface between front timing chain case and rear timing chain case

REMOVAL
WARNING:
Be careful not to get burn yourself, as engine oil and engine coolant may be hot.
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator and cylinder block. Refer to CO-11, "
Changing Engine Coolant" and
EM-124, "
DISASSEMBLY" .
NOTE:
Perform this step when removing water pipes.
3. Disconnect water hoses from oil cooler.
When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant from
spilling out.
Remaining engine coolant in piping will come out. Use a tray to collect it.
CAUTION:
Perform this step when the engine is cold.
Do not spill engine coolant on drive belts.
4. Using oil filter wrench [SST: KV10115801 (J38956)], remove oil filter. Refer to LU-10, "
OIL FILTER" .
CAUTION:
Do not spill engine oil on drive belts.
5. Remove connector bolt, and remove oil cooler.
