AUTO LIGHT SYSTEMPFP:28491
Component Parts and Harness Connector LocationAKS007ER
System DescriptionAKS007ES
Automatically turns on/off the parking lamps and the headlamps in accordance with ambient light.
Timing for when the lamps turn on/off can be selected using four modes.
OUTLINE
The auto light control system has an optical sensor inside it that detects outside brightness.
When the lighting switch is in “AUTO” position, it automatically turns on/off the parking lamps and the head-
lamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the set-
ting, refer to LT- 6 2 , "
SETTING CHANGE FUNCTIONS" .
Optical sensor, power is supplied

from BCM (body control module) terminal 17

to optical sensor terminal 1.
Optical sensor, ground is supplied

from BCM (body control module) terminal 18

to optical sensor terminal 3.
When ignition switch is turn to “ON” position, and

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

CAUTION:
Before installation, apply new engine oil to the parts as instructed in the figure.
REMOVAL
1. Remove oil pan (lower and upper) and oil strainer. Refer to EM-30, "OIL PAN AND OIL STRAINER" .
2. Remove front timing chain case and timing chain (primary). Refer to EM-63, "
TIMING CHAIN" .
3. Remove oil pump assembly.
INSTALLATION
Note to the following, and install in the reverse order of removal.

When installing, align crankshaft flat faces with oil pump inner rotor flat faces.
INSPECTION AFTER INSTALLATION
1. After warming up engine, check for engine oil leakage.
2. Check the engine oil level and add engine oil. Refer to LU-7, "
ENGINE OIL" .
Disassembly and AssemblyABS004SZ
DISASSEMBLY
1. Remove oil pump cover.
2. Remove oil pump inner rotor and oil pump outer rotor from oil pump body.

NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If the engine is already started,
stop it and allow 15 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.
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 oil leakage around the following area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Intake valve timing control cover

Intake valve timing control solenoid valve

Front cover

OIL PRESSURE CHECK
WARNING:

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

Oil pressure check should be done in “Parking position”.
1. Check engine oil level. Refer to LU-25, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.

Removal and InstallationABS006J7
REMOVAL
1. Remove front cover. Refer to EM-196, "TIMING CHAIN" .
2. Remove the oil pump drive spacer.

Set bolts in the two bolt holes [M6 × pitch 1.0 mm (0.04 in)] on
the front surface. Using suitable puller, pull oil pump drive
spacer off from crankshaft.
NOTE:
The dimension between the centers of the two bolt holes is 33
mm (1.30 in).
In the figure, a commercial steering puller is used.
3. Remove oil pump.
INSTALLATION
1. Install the oil pump.
2. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.

If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
3. Install in the reverse order of removal after this step.
1. Oil pump body 2. Oil pump outer rotor 3. Oil pump inner rotor
4. Oil pump cover 5. Oil pump drive spacer 6. Regulator valve
