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.
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.
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.

SPORT Indicator Light Display
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
11.SPORT Indicator Light Display
A: OPERATION
When any on-board diagnostics item is malfunctioning, the SPORT indicator light blinks from the time the
malfunction is detected after starting the engine until the ignition switch is turned OFF. The malfunctioning
part or unit can be determined by a DTC during the on-board diagnostics operation. Problems which oc-
curred previously can also be identified through the memory function. If the SPORT indicator light does not
show a problem (although a problem is occurring), the problem can be determined by checking the perfor-
mance characteristics of each sensor using Subaru Select Monitor. Indicator light signal patterns are shown
in the figure.
When the SPORT indicator light does not operate normally but no DTC is stored, perform the SPORT indi-
cator light inspection.
