TRUNK OPEN FUNCTION
INTELLIGENT KEY SYSTEM
System Diagram
System Description
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 OPERATIONWhen 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 (3 MPH)
- vehicle security system is disarmed or in the pre-armed phase
- Trunk lid opener cancel switch is OFF (CANCEL)
- vehicle speed is more than 5 km/h (3 MPH)
- vehicle security system is armed or in the alarm phase
OUTSIDE KEY ANTENNA DETECTION AREAThe 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 FUNCTIONWhen 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.
