ILLUMINATIONPFP:27545
System DescriptionAKS007EI
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) of IPDM E/R (intelligent power distribution module
engine room) 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

to tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 10A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)].
Power is also supplied at all times

to BCM (body control module) terminal 55

through 50A fusible link (letter M, located in fuse and fusible link block)

to BCM (body control module) terminal 42

through 15A fuse [No. 22, located in fuse block (J/B)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)]

through 15A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]

to unified meter and A/C amp. terminal 21 and

to combination meter terminal 8

through 10A fuse [No. 19, located in fuse block (J/B)].
With the ignition switch in the ON or START position, power is supplied

to BCM (body control module) terminal 38

through 15A fuse [No. 1, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22

through 10A fuse [No. 12, located in fuse block (J/B)]

to ignition relay in the IPDM E/R (intelligent power distribution module engine room)

from ignition switch

to combination meter terminal 7

through 10A fuse [No. 14, located in fuse block (J/B)].
With the ignition switch in the ACC or ON position, power is supplied

to BCM (body control module) terminal 11

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

to BCM (body control module) 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 (intelligent power distribution module engine room) terminals 38 and 60

through grounds E21, E50, and E51.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The central processing unit of the IPDM E/R controls the 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 4

to rear power window switch RH (illumination) terminal 7

through grounds B15 and B45.
With power and ground supplied, illumination lamps illuminate.
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the 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 the battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionAKS007EJ
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, check engine oil level. If engine is already started, stop it and allow 10 minutes before
checking.
1. Put vehicle horizontally.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and make sure engine oil level is within the
range shown in the figure.
4. If it is out of range, adjust it.
NOTE:
When checking 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 is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Water pump cover

Chain tensioner cover

Intake valve timing control cover and intake valve timing control solenoid valve

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Mating surface between front timing chain case and rear timing chain case

Mating surface between rear timing chain case and cylinder block and cylinder head

Crankshaft oil seal (front and rear)
