Operation

Buzzer operate after operation permission conditions are satisfied.

After buzzer operation (A pattern) ends, back door closure motor starts the open operation.

Open SW turns ON, and back door latch release operation completes.

Half latch SW turns ON, and then back door closure motor performs reverse operation and returns to the 
neutral position.

When close SW turns OFF, back door closure motor reverse operation stops, and then completes return-
ing to the neutral position.

BACK DOOR AUTO CLOSURE FUNCTION

Open Function

When back door opener switch is pressed and automatic back door main switch in the OFF position, BCM
transmits the back door open request signal to automatic back door control unit via CAN communication, and
automatic back door control unit opens back door lock assembly. 

Timing Chart (Open function)

Closure Function

When the back door is closed to the half-latch position, the motor drives to rotate the latch lever and pulls it in
from half latched to fully latched and automatically closes the door. Then, the closure motor reverses to the
neutral position.

ANTI-PINCH FUNCTION

During auto open operation, if an object is detected by encoder pulse in the door's path, a warning chime
sounds and the back door operates in the reverse direction to prevent pinching.
During auto close operation, if an object is detected by the touch sensors and encoder pulse in the door's
path, a warning chime sounds and the back door operates in the open direction until it is fully open.
