Starter Switch Check

On manual transmission vehicles, put the shift lever in NEUTRAL (N), push the clutch down halfway and try to start the engine. The starter should work only when the clutch is pushed down all the way to the floor. If the starter works when the clutch is not pushed all the way down, the vehicle needs service.

Automatic Transmission Shift Lock Control Check

  3. Firmly apply the parking brake.
  4. With the engine off, turn the key to the RUN position, but don't start the engine.
  5. Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort.
  6. If the shift lever moves out of PARK (P), the vehicle needs service.

Ignition Transmission Lock Check

  1. With the vehicle parked, set the parking brake.
  2. Try to turn the ignition key to LOCK in each shift lever position.
  3. With an automatic transmission, the key should turn to LOCK only when the shift lever is in PARK (P).
  4. With a manual transmission, the key should turn to LOCK only when you press the key release button.
  5. On all vehicles, the key should come out only in LOCK.
