(4) 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 continuity
in the other or if there is continuity at unequal points,
adjust the inhibitor switch.
G3M0294

(1) Loosen the three inhibitor switch securing bolts.
(2) Shift the select lever to the N range.
(3) Insert ST as vertical as possible into the holes in
the inhibitor switch lever and switch body.
ST 499267300 STOPPER PIN
(4) Tighten the three inhibitor switch bolts.
Tightening torque:
3.4±0.5 N⋅m (0.35±0.05 kg-m, 2.5±0.4 ft-lb)
(5) Repeat the above checks. If the inhibitor switch is
determined to be“faulty”, replace it.
