2. INHIBITOR SWITCH
The inhibitor switch allows the back-up lights to turn on
when the select lever is in the R range and the starter
motor to start when the lever is in the N or P range.
When driving condition or starter motor operation is
erroneous, first check the shift linkage for improper opera-
tion. If the shift linkage is functioning properly, check the
inhibitor switch.

(1) Disconnect cable end from select lever.
(2) Disconnect inhibitor switch side connector.
(3) Check continuity in inhibitor switch circuits with
select lever moved to each position.
CAUTION:
Also check that continuity in ignition circuit does not
exist when selector lever is in R, D, 3, 2 and 1 ranges.
NOTE:
If inhibitor switch is inoperative, check for poor contact of
connector on transmission side. (Plastic body type inhibi-
tor switch)
