CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

< BASIC INSPECTION >
DIAGNOSIS AND REPAIR WORKFLOW
8. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure described based on open circuit inspection. A short circuit inspection is also
required for the circuit check in the Diagnostic Procedure.
Is malfunctioning part detected?
YES >> GO TO 9.
NO >> Check voltage of related BCM terminals using CONSULT.
9. REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace- ment.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 10.
10. FINAL CHECK
When DTC was detected in step 2, perform DTC C onfirmation Procedure or Component Function Check
again, and then check that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Does the symptom reappear?
YES (DTC is detected)>>GO TO 8.
YES (Symptom remains)>>GO TO 6.
NO >> Inspection End.

Only when pressing the request switch, it is possibl e to open the trunk by carrying the Intelligent Key.
• The Intelligent Key system is a system that makes it possible to open the trunk (trunk open function) by car-
rying the Intelligent Key which operates based on the resu lts of electronic ID verification using two-way com-
munications between the Intelli gent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver (warning chime functions).
• When trunk is opened with request switch or remote controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer or horns sound (hazard and buzzer/horn reminder function).
• The settings for each functi on can be changed with the CONSULT.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT.
OPERATION DESCRIPTION/TRUNK OPEN
• When the BCM detects that trunk open request switch is pressed, it starts the outside key antenna (trunk
room) and inside key antenna corresponding to the pressed trunk open request switch and transmits the
request signal to the Intelligent Key. And then, c heck that the Intelligent Key is near the trunk.
• If the Intelligent Key is within the outside key ant enna (rear bumper) detection area, it receives the request
signal and transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM transmits the trunk open request signal and sounds Intelligent Key warning buzzer 4 consecutive
times.
• When BCM receives the trunk open request signal, it operates the trunk release solenoid and opens the trunk.
OPERATION CONDITION
If the following conditions are not satisfied, trunk open operation is not performed even if the request switch is
operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.
