Basic Inspection

PRE-INSPECTION FOR DIAGNOSTIC


Basic Inspection

The hybrid system start function, door lock function, power distribution system and NATS-NVIS 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 and power distribution system are operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by performing the vehicle security operation check after basic inspection.
