SYSTEM (AUTOMATIC BACK DOOR SYSTEM)
SYSTEM (AUTOMATIC BACK DOOR SYSTEM)
System Description
INFOID:0000000009648983
SYSTEM DIAGRAM
BASIC OPRATION
The automatic back door system performs the automatic open/close operation of the back door by operating
the automatic back door switch, the automatic back door close switch, the back door opener switch, and Intel-
ligent Key.
AUTOMATIC BACK DOOR OPEN/CLOSE FUNCTION
• In the case of the back door fully closed, operate the automatic back door switch, Intelligent Key or back
door opener switch with the back door unlock. The back door closure motor releases the latch, then the
automatic back door motor opens the back door to the fully open position. Reverse the closure motor to the
neutral position simultaneously.
• In the case of the back door fully open, operate the automatic back door switch, Intelligent Key or automatic
back door close switch. The automatic back door motor closes the back door to the half-latch position, then
the back door closure motor to the full latch position. Then, reverse the closure motor to the neutral position.

BACK DOOR AUTO CLOSURE FUNCTION
Open Function
When back door opener switch is pressed and automatic door main switch in the OFF position, BCM transmits
the back door open request signal to automatic back door control module via CAN communication, and auto-
matic back door control module opens back door lock assembly.
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, reverse the closure motor to the
neutral position.
WARNING FUNCTION
The warning function is as follows and gives the user warning information and warnings using automatic back
door buzzer and hazard.
Buzzer Operation Condition
ANTI-PINCH FUNCTION
During auto 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 in the door's path, a warning chime
sounds and the back door operates in the open direction until it is fully open.
