CAUTION:

If DTC relating to CAN communication [U1000] and other components are displayed at the same
time, diagnose CAN communication first.

Make sure of the normal operation after the parts (except AFS control unit) replacement according
to the self-diagnosis results. Delete the malfunction history.
Display Results

0: There is malfunction now.

1 – 39: Displays when it is normal at present and finds malfunction in the past. It increases in order
of 0→1→2...38→39 after returning to the normal condition whenever IGN OFF→ON. If it is over 39,
it is fixed to 39 until the self-diagnostic results are erased. It returns to 0 when malfunction is
detected again in the process.

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

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)

Mating surface between cylinder block and cylinder head
