PHIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

Is malfunctioning part detected?
YES >> GO TO 8.
NO >> Check voltage of related BCM terminals using CONSULT-III.
8.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 9.
9.FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Component Function Check
again, and then check that the malfunction has 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 7.
YES (Symptom remains)>>GO TO 6.

TRUNK OPEN FUNCTION : System DiagramINFOID:0000000003794746
TRUNK OPEN FUNCTION : System DescriptionINFOID:0000000003794747
TRUNK LID OPENER
 When the BCM detects that trunk lid opener request switch is pressed, it activates the outside key antenna
(rear bumper) and inside key antenna and transmits the request signal to the Intelligent Key. And then,
check that the Intelligent Key is near the trunk lid.
 If the Intelligent Key is within the outside key antenna 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 opens the trunk lid and sounds Intelligent Key warning buzzer and blinks hazard warning lamp at the
same time as a reminder.
TRUNK LID OPENER OPERATION
When trunk lid opener switch is ON, BCM opens trunk opener actuator.
BCM can open trunk lid opener actuator when
 vehicle speed is less than 5 km/h (3MPH)
 vehicle security system is disarmed or in the pre-armed phase
BCM does not open trunk lid opener actuator when
 vehicle speed is more than 5 km/h (3MPH)
 vehicle security system is armed or in the alarm phase
 Intelligent Key is inserted in key slot
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of trunk lid open function is
in the range of approximately 80 cm (31.50 in) surrounding the trunk
lid opener request switch (1). However, this operating range
depends on the ambient conditions.
HAZARD AND BUZZER REMINDER FUNCTION
When trunk lid opening operation is performed by trunk lid opener request switch, the hazard warning lamps
blink and Intelligent Key warning buzzer sounds as a reminder.
LIST OF OPERATION RELATED PARTS
The operation related parts are marked with ×.
