CHECK ENGINE/TRANSMISSION TYPE.
: Is engine/transmission type 2200 cc/MT?
: Check AT/MT identification circuit.
[T10DD0].>
: Go to step10AO2.
10AO2CHECK DTC P0106, P0107, P0108, P0403,
P1102, P1122 OR P1421 ON DISPLAY.
: Does the Subaru select monitor or OBD-II
general scan tool indicate DTC P0106,
P0107, P0108, P0403, P1102, P1122 or
P1421?
:Inspect DTC P0106, P0107, P0108, P0403,
P1102, P1122 or P1421 using“10. Diagnostics
Chart with Trouble Code”.
Manually check that EGR valve diaphragm is
not stuck.
WARNING:
Be careful when checking EGR valve, since it may be
extremely hot.
NOTE:
In this case, it is not necessary to inspect DTC P0400.
After checking the above item, go to
CONFIRMATION
OF ACTUAL DRIVING PATTERN.
: Go to step10AO3.

CHECK VACUUM LINE.
: Is there a fault in vacuum line?
NOTE:
Check the following items.
Disconnection, leakage and clogging of the two vacuum
hoses and pipes between throttle body and BPT
Disconnection, leakage and clogging of the vacuum
hose and pipe between EGR solenoid valve and BPT
Disconnection, leakage and clogging of the vacuum
hose between EGR solenoid valve and EGR valve
Disconnection, leakage and clogging of BPT pressure
transmitting hose
: Repair or replace hoses and pipes.
And after the checking and repairing, go to
CONFIRMATION OF ACTUAL DRIVING
PATTERN.
: Go to step10AO4.

CHECK OPERATION OF EGR SYSTEM.
1) Turn ignition switch to OFF.
2) Connect the test mode connector.
3) Turn ignition switch to ON.
: Does EGR solenoid valve produce operating
sound?
NOTE:
EGR control solenoid valve operation check can also be
executed using Subaru Select Monitor (Function mode:
FD05). For the procedure, refer to“COMPULSORY VALVE
OPERATION CHECK MODE”.
: Go to next step 4).
: Replace EGR solenoid valve.

4) Turn ignition switch to OFF.
5) Disconnect connector from EGR solenoid valve.
6) Connect 12 V battery’s groundterminal to one ter-
minal of the EGR solenoid valve. Then connect 12 V bat-
tery’sterminal to the other terminal of it.
CAUTION:
Do not use the 12 V battery installed in the vehicle,
because the electrical system may be damaged.
7) Start the engine.
: Does EGR valve operate at a throttle valve
opening of 5 to 10 degrees with visually
check?
: Possibly EGR valve malfunction may be due to
freezing or clogging by foreign matter. At this point
in time do not replace EGR valve, since it is not
faulty. And after the checking, go to
CONFIR-
MATION OF ACTUAL DRIVING PATTERN.
NOTE:
If malfunction is detected again in the confirmation of actual
driving pattern, EGR valve is faulty. Go to next step 8).
: Go to next step 8).
8) Turn ignition switch to OFF.
: Is there clogging in the gas outlets of intake
manifold or cylinder head, checking by
breathing into the outlets?
: Repair or replace intake manifold or cylinder
head. And go to
CONFIRMATION OF
ACTUAL DRIVING PATTERN.
: Clean EGR valve. And go toCONFIRMATION
OF ACTUAL DRIVING PATTERN.
CAUTION:
Do not use solvent when cleaning EGR valve
assembly, as it can damage diaphragm.
NOTE:
Remove and blow away the exhaust deposits. Make
sure the valve operates smoothly and the valve seat area
is completely cleaned.
Replace EGR valve as required.

CONFIRMATION OF ACTUAL DRIVING
PATTERN.
1) Conduct CLEAR MEMORY and INSPECTION MODES.
2) Connect Subaru select monitor to its data link connec-
tor.
3) Start and warm-up the engine until the radiator fan
makes one complete rotation. (All accessory switches are
OFF.)
4) Turn Subaru select monitor switch to ON.

5) Designate mode using function key.
Function mode: FA4

6) Drive at 88±5 km/h (55±3 MPH) until the LED No. 2
comes on.
NOTE:
Keep the throttle valve opening at the same degree, since
diagnosis will be interrupted when the opening varies.
Diagnosis starts in 190 seconds after starting engine and
takes 4 seconds.
Put the gear to“D”range for the diagnosis.

7) Designate mode using function key.
Function mode: FB0
8) Confirm the“No trouble”indication on Subaru select
monitor.
