    NOTICE:
    There are 1 motor and 2 sensors built into the steering lock actuator assembly.
    HINT:
    1. When taking measurements when the lock motor is stopped, it is not necessary to perform any operations.
    2. In order to take measurements when the lock motor is operating, perform either of the following operations:
      1. To unlock the steering, carry the key and turn the engine switch on (ACC) or on (IG) with the shift lever in P.
      2. To lock the steering, turn the engine switch off with the shift lever in P, and then open a door.
