Basic Inspection
INFOID:0000000000964258
The engine start function, door lock function, power distribution system and NATS-IVIS/NMS 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.
