Operation
Function Of Safety Power Window
When all door (Front, Rear) power window auto-up switch is operated, safety function is activated.
1. Safety function condition
When detect the force of 100N during the window rising, window is reversed.
2. Length of window reversing (except holding the auto-
up switch)
A.When detect the jamming during the 4mm ~ 250mm
from top of the door.
→ Window is reversed until 300mm from top of the
door.
B.When detect the jamming over the 250mm from top of the door.
→ Window is reversed until 50mm from jamming position.
→ Window is reversed 50mm or bottom position in case of 50mm reversing distance.
Language

C.When detect the jamming over 300mm from top of the door.
→ Window stops at reverse point.
3. Length of window reversing (holding the auto-up
switch)
A.When detect the jamming during holding the auto-
up switch.
→ Window is reversed until 25mm from jamming
position.
B.Auto-up function is not available during the 5 seconds from above condition.
→ When holding the auto-up switch, window is operated as a manual-up function. (Safety function is
not activated.)
C.When detect the jamming during holding the auto-up switch again.
→ Window is reversed until 25mm from jamming position.
D.When holding the auto-up switch after 5 seconds from above condition.
→ Window is reverse until 25mm from jamming position.
4. Safety function is not available area
Safety function is not available during the 4mm from top of the door.
Initializing Method Of The Safety Power Window
1. Position counter and position initialization
(1) Position counter
Window position counting is implemented by use of
one Hall Effect sensor (HEF) connected to timer
capture unit of the Controller with a resolution of
180° electrical.
Even the battery was separated from the car, it must
keep the window position information.
(2) Position initialization
For position initialization, position counter detect the
upper mechanical stop and lower mechanical
Position. Motor control unit (MCU) allow only

Manual mode activity (without ASD Anti-Squeeze
Detection algorithm) feature) before to be initialized.
Initialization means the condition to move the
window system with full anti-pinch function and
related functions by detecting the window travel
distance (Upper/Lower mechanical limits).
Conditions for initialization are
B.
C.
Switch action with De-initialized condition :
A.
B.
(3) Re-initialization
During re-initialization, position counter is set to
"zero" at upper block position to compensate
counting errors by software, mechanical tolerances
or physics. Conditions for re-initialization are
B.
C.
(4) De-initialization
The system initialization/calibration will be lost in the
following cases:
B.
C.
D.
E.
F.

-
(5) Soft stop function
In order to reduce noise and mechanical stress, the
window movement is stopped under control of the
ECU before the bottom position is reached.
The clearance is 0 / +10 mm (at 11.5 V to 14.5 V).
To activate the soft bottom stop function, the top
reference position and bottom reference position
have to be initialized. Therefore, the window is lifted
into the top position until the block condition is
detected. This position is taken as top reference
position.
Afterwards, the window is moved to the bottom
position until the block condition is detected
(mechanical stop). This position is taken as bottom
reference position.
The bottom reference position is re-initialized :
B.
(6) Thermal protection
Thermal protection by software module is implemented to prevent from destruction of motor during
overload condition. Motor temperature is estimated by integrating squared motor current as an
estimate for heating power integral. When estimated motor temperature exceeds EEPROM
programmable upper limit, motor is deactivated for fixed delay time (default value = 30 sec.)
Thermal shutdown during a window operation will not interrupt the operation due to safety reasons.
(7) Operation time limiter
Maximal operation time of power window motor is limited to 15 sec (EEPROM programmable).
(8) Continuous reverse
Current Number of Continuous reverse of window is
5. With the below condition, this counter Will be
initialized.

Inspection
Front Power Window Motor
1. Remove (-) negative battery terminal.
2. Remove the front door trim. (Refer to the Body group-front door)
3. Disconnect the connector from the motor.
(A : Safety, B : Standard)
Language
4. Connect the motor terminals directly to battery voltage (12V) and check that the motor operates smoothly.
Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. If the
operation is abnormal, replace the motor.
Rear Power Window Motor
1. Remove (-) negative battery terminal.
2. Remove the rear door trim. (Refer to the Body group-rear door)
3. Disconnect the connector from the motor.
4. Connect the motor terminals directly to battery voltage (12V) and check that the motor operates smoothly.
Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. If the
operation is abnormal, replace the motor.
