Mitsubishi Outlander XL. Manual — part 356

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 8.

NO:

The Inspection is complete.

STEP 8. Test the OBD-II Drive Cycle.

(1)

Carry out test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 21 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1020 set?

YES:

Retry the trouble shooting.

NO:

The Inspection is complete.

CIRCUIT OPERATION

｠

The engine oil control valve power is supplied from
the MFI relay (terminal No. 2).

｠

The ECM controls ground engine oil control valve
by turning the power transistor in the ECM "ON" and
"OFF".

TECHNICAL DESCRIPTION

｠

The engine oil pressure switches the cams to
operate the MIVEC system in the low-speed or
high-speed mode in accordance with the signals
from the ECM.

DESCRIPTIONS OF MONITOR METHODS

Circuit voltage stays low when solenoid status is off.
