3. CLEAR MEMORY MODE
1) On the «Main Menu» display screen, select the
{2. Each System Check} and press the [YES] key.
2) On the «System Selection Menu» display screen,
select the {Transmission Control System} and press
the [YES] key.
3) Press the [YES] key after the information of
transmission type is displayed.
4) On the «Transmission Diagnosis» display screen,
select the {Clear Memory} and press the [YES] key.
5) When the “Done” is shown on display screen,
turn the Subaru Select Monitor and ignition switch
to OFF.
NOTE:
 For details concerning operation procedure, refer
to the SUBARU SELECT MONITOR OPERATION
MANUAL.
 When {Clear Memory 2} is selected and executed,
DTC and learned control memory is cleared. If Clear
Memory 2 is performed, execute the learning con-
trol. OF LEARNING CONTROL, OPERATION, Subaru

4. FACILITATION OF LEARNING CON-
TROL
1) Shift the select lever to “P” range, and apply
parking brake.
2) Lift-up the vehicle.
3) Connect the Subaru Select Monitor to data link
connector, and then turn the ignition switch to ON.
4) Perform the {Clear Memory 2} using Subaru Select
Monitor. ORY MODE, OPERATION, Subaru Select Monitor.>
5) Using Subaru Select Monitor, check that the DTC
is not output. AGNOSTIC TROUBLE CODE, OPERATION, Sub-
aru Select Monitor.>
6) Warm-up the engine until the ATF temperature
which is displayed on the Subaru Select Monitor is
within 60 — 90°C (140 — 194°F). 4AT(H4DOTC)-15, READ CURRENT DATA, OP-
ERATION, Subaru Select Monitor.>
7) Shift the select lever to “R” range.
8) Turn all switches including headlight, air condi-
tioner, seat heater, rear defogger and etc. to OFF.
9) Turn the ignition switch to OFF.
10) Depress the brake pedal fully until the facilitation
of learning control is completed when the “Communi-
cation Failed!” is displayed on Subaru Select Monitor.
11) Turn the ignition switch to ON.
12) Check that the Subaru Select Monitor is re-
turned to normal operation.
13) Shift the select lever to “P” range, and then wait
for more than 3 seconds.14) Shift the select lever to “R” range, and then wait
for more than 3 seconds.
15) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
16) Shift the select lever to “D” range, and then wait
for more than 3 seconds.
17) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
18) Slightly depress the accelerator pedal fully.
19) Slightly release the accelerator pedal fully.
20) Start the engine, and idle it.
21) Shift the select lever to “D” range.
22) Start the facilitation of learning control. At this
time, the POWER indicator light in combination meter
blinks at 2 Hz. When the POWER indicator light does
not blink, turn the ignition switch to OFF and repeat
the procedures from step 4). When the POWER indi-
cator light which blinking at 2 Hz changes to blink at
0.5 Hz, facilitation of learning control is completed.
NOTE:
When blinking of POWER indicator light changes
from 2 Hz to 4 Hz during facilitation of learning con-
trol, repeat the procedure from step 4).
23) Shift the select lever to “N” range, and then turn
the ignition switch to OFF.
24) Shift the select lever to the “P” range, and then
complete the facilitation of learning control.
