AUTOMATIC TRANSMISSION

INHIBITOR SWITCH

12.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.
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 “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-50,
ADJUSTMENT, Inhibitor Switch.>

• Except model with SPORT shift

• Model with SPORT shift

4) Repeat the above checks. If there are abnormal-
ities, adjust the select cable. <Ref. to CS-14, AD-
JUSTMENT, Select Cable.>
