The engine start function, door lock function, power di stribution 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 basic inspection to i dentify 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.
1.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.
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-210, "
Symptom Table".
2.CHECK ENGINE STARTING
Check that the engine starts when operating the Intelligent Key.
Does the engine start?
YES >> GO TO 3.
NO >> Refer to SEC-115, "
Symptom Table".
3.CHECK STEERING LOCKING
Does the steering lock when operating door switch after switching the power supply from ON position (or ACC
position) to LOCK position?
If door switch is malfunctioning, BC M cannot lock the steering. If BCM does not detect DTC, steering lock unit
is normal.
Does steering lock?
YES >> GO TO 4.
NO >> Refer to DLK-71, "
ComponentFunctionCheck".
4.CHECK IGNITION KNOB SWITCH OPERATION
Press ignition knob to check switch operation.
Does the combination meter display any message?
YES >> GO TO 5.
NO >> Refer to SEC-53, "
Ignition Knob Switch Check".
5.CHECK VEHICLE SECURITY SYSTEM
Check the vehicle security system for normal operation.
The vehicle security function can operate only when t he door lock and power distribution functions are operat-
ing 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-7, "
Vehicle Security Operation Check".
