On-Vehicle Inspection

WARNING: This page is about a different car, the 2006 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY 
    1. Apply the parking brake.
    2. Turn the engine switch on (IG).
    3. Depress the brake pedal and check that the engine starts when the shift lever is set in the N or P position, but does not start in other positions.
    4. Check that the back-up light comes on and the reverse warning buzzer sounds when the shift lever is set in the R position, but the light and buzzer do not operate in other positions.

      If a failure is found, check the park/neutral position switch for continuity.
