CAUTION:

If plural DTCs (including [U1000] CAN COMM CIRCUIT) are displayed, start the diagnosis from
CAN communication circuit.

If NO DTC is displayed at self-diagnosis after any parts other than AFS control unit are replaced,
erase the error history.
Timing Display Has 2 Displays: the Trip Number Counter Display and the CURRENT/PAST Display.

Trip number counter display (U1000, U1010)
“0”: Displays DTC detected when there is malfunction now or trip 0.
“1” - “39”: Displays when it is normal now and finds malfunction in the past. It increases like “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 mal-
function is detected again in the process.

CURRENT/PAST display (B2515, B2516, B2517, B2520, and B2521)
CURRENT: Displays DTC detected when there is malfunction now or trip 0.
PAST: Displays DTC when it is normal now and finds malfunction in the past. It is fixed to PAST
until the self-diagnostic results are erased. It returns to CURRENT when malfunction is detected
again in the process. (In B2520 ST ANGLE SEN CALIB, automatically erases the results after the
steering angle sensor adjustment is completed normally. It is not erased even if “ERASE” is per-
formed.)

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.
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 area.

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

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

Front cover

Mating surface between cylinder block and lower cylinder block

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

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

Engine oil pressure check should be in “ Parking position”.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove splash guard (RH).
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
