Inhibitor Switch: Inspection

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.
   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 "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. < Ref. to , ADJUSTMENT . >
