•Detected when two consecutive driving cycles with fault occur.
•GENERAL DESCRIPTION
- OVER-ADVANCED (BANK 1), Diagnostic Trouble Code (DTC) Detecting Criteria.>
TROUBLE SYMPTOM:
•Engine stalls.
•Erroneous idling
CAUTION:
After repair or replacement of faulty parts, perform Clear Memory Mode
OPERATION, Clear Memory Mode.> and Inspection Mode
Mode.>.
Step Check Yes No
1CHECK ANY OTHER DTC ON DISPLAY.Is any other DTC displayed? Inspect the rele-

Code (DTC).>
Go to step 2.
2CHECK CURRENT DATA.
1) Start the engine and let it idle.
2) Measure the AVCS system operating angle
and oil flow control solenoid valve duty output
using Subaru Select Monitor or general scan
tool.
NOTE:•Subaru Select Monitor
For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”.
to EN(H6DO)(diag)-26, Subaru Select Moni-
tor.>
•General scan tool
For detailed operation procedure, refer to the
general scan tool operation manual.
Is the AVCS system operating
angle approx. 0 deg., and oil
flow control solenoid valve duty
output approx. 10%?
Check the follow-
ing item and repair
or replace if nec-
essary.
•Oil pipe (clog)
•Oil flow con-
trol solenoid
valve (clog or
dirt of oil rout-
ing, setting of
spring, clog of
valve)
•Intake cam-
shaft (dirt, dam-
age of
camshaft)
•Timing chain
(matching of
timing mark)
A temporary mal-
function. Perform
the following, and
clean the oil rout-
ing.
Replace the
engine oil and idle
the engine for 5
minutes, and then
replace the oil filter
and engine oil.
