Kia Sorento: 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.

| 4. |
Safety function is not available area
Safety function is not available during the 4mm from top of the
door.
|
Normalization (Teaching)
After power on reset or error detection, the motor has to be nomalized
at the fully closed position.
How to be nomalized:
| • |
Move the window upwards into the fully closed position. As the
window reaches the fully closed position, hold the power window switch
in auto for T≥2 seconds.
If the block is reconized, the system state turns to normalized.
|
Recall And Storing The Normalization (teaching) Information
ECU records the normalization information into the specified location
in Flash ROM. (as long as Flash ROM page is valid)
| • |
Stroing conditions : Entering to sleep mode after valid switch
input. Entering to low voltage(7.5V) after valid switch input.
|
| • |
Recall conditions : Engine=ON or Power ON reset
|
Denormalization (Memory reset)
Under conditions below, ECU turns to denormalized status. After demormalization,
auto up and safety function shall not be operated. In order to make these function
active again, ECU should go through the mormalization process.
| • |
Denormalization conditions :
|
| 1. |
Continuous 15 times reverses
|
| 2. |
Power off during motor operation
|
| 3. |
Driver side door opened and window glass is at the bottom (hard
stop position) with IGN on, IGN off → within 2 sec, IGN on → Press Manual
Down switch 3 times within 5 sec → De-normalization

Window Position Control
To detect the window position and direction of motor rotation, hall sensors
are employed. ECU recognizes the fully closed position of the window and sets
this relative window position value as "0". When the window goes downwards,
based on the information from the hall sensor, the relative position value increments.
On the contrary, when the window goes upwards, it decrements.
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.
Operation Time Limiter
Maximal operation time of power window motor is limited to 15 sec (EEPROM
programmable).
