SYMPTOM DIAGNOSIS
SECURITY CONTROL SYSTEM
Symptom TableINFOID:0000000003815090
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. Narrow down the functional area in question
by performing following table 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 following table.
Use the chart below to help you find the cause of the symptom. The numbers indicate the order of the inspec-
tion.
NOTE:
Before starting vehicle security system operation check, the following conditions must be met.
 Open front windows
 Turn ignition switch OFF
 Pull out Intelligent Key from key slot.
