PRE-INSPECTION FOR DIAGNOSTIC

Basic Inspection

INFOID:0000000001097890

The engine start function, door lock function, and NATS 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 is
operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by perform-
ing the vehicle security operation check after basic inspection.

1.

CHECK DOOR LOCK OPERATION

Check the door lock for normal operation with the Intelligent Key and door request switch.
Successful door lock operation with the Intelligent Key and request switch indicates that the remote keyless
entry receiver and inside key antenna required for engine start are functioning normally.
Identify the malfunctioning point by referring to the DLK section if the door cannot be unlocked.

Can the door be locked with the Intelligent Key and door request switch?

YES

>> GO TO 2.

NO

>> Refer to 

DLK-203, "INTELLIGENT KEY : Symptom Table"

.

2.

CHECK IGNITION KNOB SWITCH OPERATION-1

With all registered Intelligent Keys, check if ignition knob can rotate when carrying Intelligent Key inside the
vehicle.

Does ignition knob rotate?

YES

>> GO TO 3.

NO

>> Refer to 

SEC-149, "Symptom Table"

.

3.

CHECK IGNITION KNOB SWITCH OPERATION-2

Insert registered mechanical key into key cylinder, and check if ignition knob can rotate. Check for all regis-
tered mechanical keys.

Does ignition knob rotate?

YES

>> GO TO 4.

NO (Does not rotate with some of mechanical keys)>>Perform mechanical key registration.
NO (Does not rotate with all mechanical keys)>>Refer to 

SEC-149, "Symptom Table"

.

4.

CHECK VEHICLE SECURITY SYSTEM

Check the vehicle security system for normal operation.
The vehicle security function can operate only when the door lock function is operating normally. 
Therefore, it is easy to identify any factor unique to the vehicle security by performing the vehicle security
operation check after this basic inspection.

>> Go to 

SEC-150, "Vehicle Security Operation Check"

.
