System DescriptionINFOID:0000000001328383
Control of the parking, license plate, side marker and tail lamp operation is dependent upon the position of the
lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body
control module) receives input signal requesting the parki ng, license plate, side marker and tail lamps to illumi-
nate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication lines. CPU (central processi ng unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs pow er to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp cont rol unit is controlled, and a tail lamp (LED) is made to
turn ON.

1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
• Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and boltholes.
2. Wipe the liquid gasket application surface and the ma ting surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Apply liquid gasket to the liquid gasket application surface. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-44
.
 Within five minutes of liquid gasket application, install the mating component.
 If liquid gasket protrudes, wipe it off immediately.
 Do not retighten after mounting bolts and nuts the installation.
 After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.

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 highl y 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
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
 Mating surface between rear timing chain case and oil pan (upper)

ENGINE OIL
WARNING:
• Be careful not to get burn your
self, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to "ENGINE OIL LEVEL".
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engi ne oil temperature at 80 °C (176 °F)]
Unit: kPa (kg/cm2, psi)
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-44, "
Recommended Chemical Prod-
uct and Sealant".

WARNING:
 Be careful not to get burn yourself, as engine oil may be hot.
 Prolonged and repeated contact with used engine
oil may cause skin cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thorough ly with soap or hand cleaner as
soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-5, "
Inspec-
tion".
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "
Component (2WD Models)".
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Engine oil specificat ion and viscosity:
Refer to MA-9, "
Fluids and Lubricants".
Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:
 When filling engine oil, do not pull out oil level gauge.
 The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
 Always use oil level gauge to determine the proper amount of engine oil in engine.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level. Refer to LU-5, "
Inspection".
