Inhibitor Switch
13.Inhibitor Switch
A: INSPECTION
When the driving condition or starter motor opera-
tion is erroneous, first check the shift linkage for im-
proper operation. If the shift linkage is functioning
properly, check the inhibitor switch.
1) Disconnect the inhibitor switch connector.
2) Check continuity in inhibitor switch circuits with
the select lever moved to each position.
NOTE:
 Also check that continuity in ignition circuit does
not exist when the select lever is in “R”, “D”, “3”, “2”
and “1” ranges.
 If the inhibitor switch is inoperative, check for
poor contact of connector on transmission side.3) Check if there is continuity at equal points when
the select lever is turned 1.5° in both directions
from the “N” range to “R” range or “D” range
If there is continuity in one direction and the conti-
nuity in the other or if there is continuity at unequal
points, adjust the inhibitor switch. ADJUSTMENT, Inhibitor Switch.>
4) Repeat the above checks at other ranges. If
there are abnormalities, adjust the select cable.

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.

ATF Cooler Pipe and Hose
C: INSPECTION
Repair or replace any defective hoses, pipes,
clamps, and washers found from the inspection be-
low.
1) Check for ATF leaks in joints between the trans-
mission, radiator, pipes, and hoses.
2) Check for deformed clamps.
3) Lightly bend the hose and check for cracks in the
surface and other damage.
4) Pinch the hose with your fingers and check for
poor elasticity. Also check for poor elasticity in the
parts where the clamp was installed by pressing
with your fingernail.
5) Check for peeling, cracks, and deformation at
the tip of the hose.
