PRE-INSPECTION FOR DIAGNOSTIC

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.

CHECK DOOR LOCK OPERATION

Check the door lock for normal operation with the Intelligent Key controller and door request switch.
Successful door lock operation with the Intelligent Key and request SW indicates that the remote keyless
entry receiver and inside key antenna required for engine start are functioning normally.
