Neutral Safety Switch: Service and Repair
Inhibitor SwitchINSPECTION
When the driving condition or starter motor operation is erroneous, first check the shift linkage for improper 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 continuity in the other or if there is continuity at unequal points, adjust the inhibitor switch.
4. Repeat the above checks. If there are abnormalities, adjust the select cable.
ADJUSTMENT
1. Shift 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 inhibitor switch lever and switch body.

4. Tighten the three inhibitor switch bolts.
Tightening torque: 3.5 Nm (0.35 kgf-m, 2.5 ft. lbs.)
5. Repeat the above checks. If the inhibitor switch is determined to be "faulty", replace it.
REMOVAL
1. Set the vehicle on a lift.
2. Move the select lever to "N" range.
3. Remove the air cleaner case.
4. Disconnect the inhibitor switch connector.
5. Remove the inhibitor switch connector from stay.
6. Lift-up the vehicle.
7. Remove the front and center exhaust pipes.
8. Remove the snap pin and washer from range select lever.
