SYSTEM DIAGRAM

• When sliding door control unit detects the vehicle speed during auto open operation or detects that sliding

door is open during vehicle driving, sliding door control unit sounds automatic sliding door warning buzzer
warning the driver, simultaneously stops automatic sliding door motor operation, operates clutch, and then
holds sliding door.

• During hold function operation, when sliding door control unit detects half latch status, sliding door control

unit stops hold function and operates sliding door auto closure function.

• During hold function operation, when sliding door control unit detects sliding door handle operation, sliding

door control unit stops clutch operation. Sliding door can be closed manually.

• When hold function is stopped according to sliding door handle operation and sliding door is manually

moved to open direction, sliding door control unit judges sliding door moving direction according to encoder
pulse signal, operates clutch again, and holds sliding door.

HOLD FUNCTION : Fail-safe

ANTI-PINCH FUNCTION : System Description

INFOID:0000000009649004

SYSTEM DIAGRAM

Reverse operation is performed when pinching of foreign materials is detected during automatic sliding door
auto open/close operation. Sliding door control unit stops automatic operation and enters into intermittent
clutch, when pinching during auto close operation is continuously detected for 3 times or more.

DETECTION ACCORDING TO ENCODER

• During automatic operation when operation speed is reduced or sliding door motor operation load is

increased due to pinching of foreign materials, sliding door control unit judges the pinching according to
change in encoder pulse signal detected from encoder. Sliding door control unit stops automatic operation,
and then automatically operates sliding door in reverse direction. Sliding door control unit stops automatic
sliding door motor at the sliding door fully open or fully closed position.

• During auto close operation when the vehicle starts driving, auto close operation does not stop and contin-

ues to operate, although operation speed may be reduced or sliding door motor operation load may be
increased due to pinching of foreign materials.

DETECTION ACCORDING TO SLIDING DOOR TOUCH SENSOR

• When the vehicle is in stop status and sliding door front end pinches foreign materials during auto close

operation, sliding door control unit judges the pinching according to sliding door touch sensor signal, oper-
ates sliding door in reverse direction, and operates auto open operation to the fully open position.

• When sliding door is in lock status and sliding door front end pinches foreign materials during sliding door

auto closure operation, sliding door control unit judges the pinching according to sliding door touch sensor
signal, and stops sliding door auto closure operation.

• When sliding door is in unlock status and sliding door front end pinches foreign materials during sliding door

auto closure operation, sliding door control unit judges the pinching according to sliding door touch sensor
signal, stops sliding door auto closure operation, and operates sliding door auto open operation to the fully
open position.

CAUTION:

Be careful that sliding door may not operate in reverse direction because load may not be detected
when thin or soft foreign materials are pinched.

ANTI-PINCH FUNCTION : Fail-safe

INFOID:0000000009649005

FAIL-SAFE CONTROL BT DTC

Sliding door control unit performs fail-safe control when any DTC is detected.
