The engine start function, door lock function, and NATS in the Intelligent Key system are closely related to
each other regarding control. Narrow down the functional area in question by performing basic inspection to
identify which function is malfunctioning. The vehicle security function can operate only when the door lock is
operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by perform-
ing the vehicle security operation check after basic inspection.
