Inhibitor Switch: Inspection

When the driving condition or starter operation is improper, first check the shift linkage for improper operation. If the shift linkage is functioning properly, check the inhibitor switch.

Remove the intercooler. Ref. to INTAKE (INDUCTION) (H4DOTC)>INTERCOOLER>REMOVAL .

Check for continuity in inhibitor switch circuit by shifting the select lever in "P", "R", "N" and "D".

NOTE:

Check that there is no continuity in the starter circuit when the select lever is in the "R" and "D" ranges.
When inhibitor switch is normal, check there is no poor contact in vehicle side connector and no open circuit in harness.

Check that there is continuity at equal points when the select lever is moved 1.5° in both directions from the "N" range.
If there is continuity in only one direction or in other points, adjust the inhibitor switch. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>INHIBITOR SWITCH>ADJUSTMENT .
