PROCEDURE
INSPECT PARK/NEUTRAL POSITION SWITCH OPERATION
Apply the parking brake.
Turn the ignition switch to ON.
Depress the brake pedal and check that the engine starts when the shift lever is in N or P, but does not start in any other position.
Check that the back-up light illuminates and the reverse warning buzzer sounds only when the shift lever is in R, but does not function in any other position.
If a malfunction or failure is found, check the park/neutral position switch for continuity.
