System DescriptionNKS003TH
Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated)
the BCM (body control module) receives input signal requesting the illumination lamps to illuminate. This input
signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN
communication lines. The CPU (central processing unit) located in the IPDM E/R controls the tail lamp relay
coil. This relay, when energized, directs power to the illumination lamps, which then illuminate.

Power is supplied at all times
through 15A fuse (No. 71, located in IPDM E/R)

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.

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
WAR NING :
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.
