Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
BA:DTC P0171 SYSTEM TOO LEAN (BANK 1)
1. OUTLINE OF DIAGNOSIS
Detect fuel system malfunction by the amount of main feedback control.
Diagnostic method
Fuel system is diagnosed by comparing the target air fuel ratio calculated by ECM with the actual air fuel ra-
tio measured by sensor.
2. ENABLE CONDITIONS
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously at idling or at a constant speed after warming up the engine.
4. DIAGNOSTIC METHOD
Abnormality Judgment
Compare the diagnosed value (fsobd) with the threshold value, and if a condition where the malfunction cri-
teria below are met continues for more than 50 seconds, judge that there is a fault in the fuel system.
Time Needed for Diagnosis: 10 seconds × 5 times
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK when the malfunction criteria below are completed for 10 seconds or more.

CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself at measurement.
1) Before checking the ignition timing, check the
following item:
(1) Check the air cleaner element is free from
clogging, spark plugs are in good condition, and
hoses are connected properly.
(2) Check the malfunction indicator light does
not illuminate.
2) Idle the engine.

OFF.
4) Insert the cartridge to Subaru Select Monitor.
5) Connect the Subaru Select Monitor to data link
connector.
6) Turn the ignition switch to ON and Subaru Select
Monitor switch to ON.
7) Select {Each System Check} in Main Menu.
8) Select {Engine} in Selection Menu.
9) Select {Current Data Display & Save} in Engine
Control System Diagnosis.
10) Select {Data Display} in Data Display Menu.

idle speed.
Ignition timing [BTDC/rpm]:
15°±8°/650
If the timing is not correct, check the ignition control
system. Refer to Engine Control System. EN(H6DO)(diag)-2, Basic Diagnostic Procedure.>

10.Learning Control
A: GENERAL DESCRIPTION
Be sure to perform the {Clear Memory 2} only when
the following services have been performed. And
when the shifting shock is occurred during the total
check with vehicle driving, perform the learning
with following procedures. CLEAR MEMORY MODE, OPERATION, Subaru
Select Monitor.>
•Replacement of TCM
•Replacement of transmission assembly
•Simultaneous replacement of TCM and trans-
mission assembly
•Replacement of each clutch
•Replacement of control valve body
CAUTION:
When {Clear Memory 2} is executed, DTC may
not be cleared.
B: PROCEDURE
1) Turn the ignition switch to ON.
2) Turn the air conditioner switch to OFF.
3) Turn the headlight switch to OFF.
4) Turn the rear defogger switch to OFF.
5) Start the engine.
6) Connect the Subaru Select Monitor to the vehi-
cle.
7) Drive the vehicle for 5 — 10 km (3 — 6 mile) to
warm up ATF temperature more than 70 °C (158
°F).
8) While checking that the throttle opening angle on
Subaru Select Monitor is within the specified range,
shift the gear from 1st → 2nd, 2nd → 3rd, and 3rd
→ 4th, while driving the vehicle at “D” range. to 5AT(diag)-15, READ CURRENT DATA, OPER-
ATION, Subaru Select Monitor.>
Acceleration opening angle:
12.5%±2%
9) While checking that the throttle opening angle on
Subaru Select Monitor is within the specified range,
upshift the gear from 4th → 5 t h w h i l e d r i v i n g t h e v e -
hicle at “D” range.
Acceleration opening angle:
15.5%±2%
10) Repeat the steps 8) and 9) until the reducing ef-
fect of the shifting shock is felt.
11) If reducing of shifting shock is not felt after 5 cy-
cles, recheck that the learning conditions (throttle
opening angle, ATF temperature, etc.) are as spec-
ified and recheck that other parts are normal.
