Inhibitor Switch - Subaru Legacy 2002 Service Manual

12. Inhibitor Switch

A: INSPECTION
When driving condition or starter motor operation
is erroneous, first check the shift linkage for
improper operation. If the shift linkage is function-
ing properly, check the inhibitor switch.
1) Disconnect inhibitor switch connector.
2) Check continuity in inhibitor switch circuits with
select lever moved to each position.
NOTE:
Also check that continuity in ignition circuit does
not exist when select lever is in R, D, 3, 2 and 1
ranges.
NOTE:
If inhibitor switch is inoperative, check for poor con-
tact 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.
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. <Ref. to AT-29,
ADJUSTMENT, Inhibitor Switch.>
(A) Continuity does not exist.
(B) Continuity exists.
(C) 1.5°
4) Repeat the above checks. If there are
abnormalities, adjust the select cable. <Ref. to
CS-11, ADJUSTMENT, Select Cable.>
B: ADJUSTMENT
1) Shift the select lever to the N range.
2) Loosen the three inhibitor switch securing bolts.
3) Insert ST as vertical as possible into the holes
in the inhibitor switch lever and switch body.

4) Tighten the three inhibitor switch bolts.
Tightening torque:
3.5 N·m (0.35 kgf-m, 2.5 ft-lb)
5) Repeat the above checks. If the inhibitor switch
is determined to be "faulty", replace it.
