Air Bleeding of Control Valve
18.Air Bleeding of Control Valve
A: PROCEDURE
1) Lift-up the vehicle with shifting the select lever to
“P” range and applying the parking brake.
2) Connect the Subaru Select Monitor to the vehi-
cle.
3) Make sure there is no trouble code using Subaru
Select Monitor.
4) Using Subaru Select Monitor, check that the
ATF temperature is in less than 60°C (140°F).
nostic Procedure.>
5) Power OFF the Subaru Select Monitor.
6) Turn the ignition switch to “OFF”.
7) Shift the select lever to “R” range.
8) Depress the brake pedal fully until the air bleed-
ing is completed.
9) Turn the ignition switch to ON.
10) Shift the select lever to “P” range, and then wait
for more than 3 seconds.
11) Shift the select lever to “R” range, and then wait
for more than 3 seconds.
12) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
13) Shift the select lever to “D” range, and then wait
for more than 3 seconds.
14) Shift the select lever to “N” range, and then wait
for more than 3 seconds.
15) Slightly depress the accelerator pedal fully.
16) Slightly release the accelerator pedal fully.
17) Start the engine.
18) Shift the select lever to “D” range.
19) Turn the Subaru Select Monitor switch to ON.
20) Select {Each System Check} in «Main Menu»
of Subaru Select Monitor.
21) On the «System Selection Menu» display
screen, select the “Transmission”. Air bleeding of
control valve starts on transmission. At this time,
the POWER indicator light in combination meter
blinks at 2 Hz. When the POWER indicator light
does not blink, repeat the procedures from step 4).
22) Air bleeding of control valve is finished when
blinking of POWER indicator light in combination
meter changes from 2 Hz to 0.5 Hz.
NOTE:
When blinking of POWER indicator light changes
from 2 Hz to 4 Hz during air bleeding, 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
finish the air bleeding.
