WARNING: This page is about a different car, the 2008 Toyota Yaris. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT SHIFT LOCK CONTROL ECU SUBASSEMBLY 
    1. Check the shift lock operation.
      1. Move the shift lever to P.
      2. Turn the ignition switch OFF.
      3. Check that the shift lever cannot be moved to any position other than P.
      4. Turn the ignition switch ON, depress the brake pedal and check that the shift lever can be moved to other positions.
    2. Check the shift lock release button operation.
      1. When operating the shift lever with the shift lock release button pressed, check that the lever can be moved to any position.

        If the operation cannot be performed as specified, check the shift lever assembly.

    3. Check the key interlock operation.
      1. Turn the ignition switch ON.
      2. Depress the brake pedal and move the shift lever to any position other than P.
      3. Check that the ignition switch cannot be turned OFF.
      4. Move the shift lever to P, turn the ignition switch OFF and check that the key can be removed.

        If the results are not as specified, inspect the shift lock control unit.

    4. Inspect the shift lock control unit assembly.
      1. Measure the voltage of the connector.

        HINT:

        Do not disconnect the shift lock control ECU connector.
