Description

INFOID:0000000006939137

Check that vehicle is under the condition shown in “Conditions of vehicle” before starting diagnosis, and check
each symptom.
NOTE:
The engine start function, door lock function, power distribution system, and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding control. The vehicle security function can operate only
when the door lock and power distribution system are operating normally.

Conditions of Vehicle (Operating Conditions)

• “ENGINE START BY I-KEY” in “WORK SUPPORT” is ON when setting on CONSULT.
• Intelligent Key is not inserted in key slot.
• One or more of Intelligent Keys with registered Intelligent Key ID is in the vehicle.
