13.Inhibitor Switch
A: INSPECTION
When the driving condition or starter motor opera-
tion is improper, 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 there is no continuity in ignition
circuit when the select lever is in the "R", "D", "3",
"2" and "1" ranges.
• If the inhibitor switch does not operate, check for
poor contact of the connector on transmission side.

3) Check that there is continuity at equal points
when the select lever is leaned 1.5° in both direc-
tions from the "N" range.
If there is continuity in only one direction or in other
points, adjust the inhibitor switch. <Ref. to 4AT-47,

4) Repeat the above checks. If there are abnormal-
ities, adjust the select cable. <Ref. to CS-28, AD-
JUSTMENT, Select Cable.>
B: ADJUSTMENT
1) Set the select lever to "N" range.
2) Loosen the three inhibitor switch securing bolts.
3) Insert the 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:

5) Repeat the above checks. If the inhibitor switch
is determined to be "faulty", replace it.
C: REMOVAL
1) Set the vehicle on a lift.
2) Set the select lever to "N" range.
3) Remove the air intake chamber. (Non-turbo
model) <Ref. to IN(H4SO)-6, REMOVAL, Air Intake
Chamber.>
4) Remove the intercooler. (Turbo model) <Ref. to
