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.

SYSTEM (AUTOMATIC BACK DOOR SYSTEM)

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.
