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.
