Combination
Switch Inspection" .
Optical Sensor System InspectionAKS007F5
1. CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
Select “BCM” on CONSULT-II. With “HEAD LAMP” data monitor,
make sure “OPTICAL SENSOR”, check difference in the voltage
when the auto light sensor is illuminated and not illuminated.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If
the optical sensor is insufficiently illuminated, the measured
value may not satisfy the standard.
Without CONSULT-II

OIL FILTER BRACKET (AWD)PFP:15238
Removal and InstallationABS007ZS
REMOVAL
WARNING:
Be careful not to burn yourself, as engine oil may be hot.
1. Remove front engine undercover with power tool.
2. Using oil filter wrench [SST: KV10115801 (J-38956)], remove oil filter. Refer to LU-10, "
OIL FILTER" .
3. Remove oil cooler connector bolt, and then oil cooler.
4. Disconnect oil temperature sensor and oil pressure switch harness connector.
5. Remove oil filter bracket from oil pan (upper).

ENGINE MAINTENANCE (VK45DE ENGINE)
Revision: 2004 November 2004 FX35/FX45
Checking Fuel LinesALS000GS
Inspect fuel lines and tank for improper attachment, leaks, cracks,
damage, loose connections, chafing or deterioration. If necessary,
repair or replace damaged parts.
Changing Air Cleaner FilterALS000GT
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning between replacement intervals. Refer to MA-7,
"PERIODIC MAINTENANCE" .
1. Remove air duct (inlet), air cleaner case and mass air flow sensor assembly. Refer to EM-172, "
AIR
CLEANER AND AIR DUCT" .
2. Remove air cleaner filter from air cleaner case.
Changing Engine OilALS000H7
WARNING:

Be careful not to 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 thoroughly
with soap or hand cleaner as soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up engine, put vehicle horizontally and check for oil leak-
age from engine components. Refer to LU-25, "
ENGINE OIL
LEAKAGE" .
3. Stop engine and wait for 15 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-181, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (US qt, Imp qt)
CAUTION:

The refill capacity depends on the engine oil 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 the engine.
8. Warm up engine and check area around drain plug and oil filter for oil leakage.
