PROCEDURE
INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY OPERATION
Turn the engine switch on (IG).
Fully apply the parking brake and chock all 4 wheels.
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 assembly for continuity.
