How To Initialize The Safety Power Window

When the battery power is removed for over 5 minutes, safety power window switch needs the initializing.

1. Power window operation before initializing
   • Manual-Up/Down function is available
   • Auto-Up/Down function is not available

     (If the Auto-up/down switch is being pushed, the manual up/down function is operated.)

2. Initialization

   Close the window in window open position, and holding the switch in window full close position over the 0.2 second.

   (If start the closing the window in window full close position, initializing could be failed.)

3. If initialize the safety power window in jamming status, could occur below conditions.
   • Safety function is not available
4. Window position memorizing hall sensor is used to identify the window position and motor operation direction. ECU detects the uppermost position of the window and sets the position as '0'
5. Deinitialization

   ECU is deinitialized if the following conditions are met. After deinitialization process, Auto-up and safety function are not activated. Deinitialization conditions

   1. Repeating window downward movement 15 times in a row.
   2. Power supply is suspended while the motor is in operation.
   3. Driver seat door opens, IGN Off with the window glass positioned in Hard Stop -> IGN On within 2 seconds -> within 5 seconds with IGN On, entering manual down switch signal 3 times -> Deinitialization completed (if power is not on in 2 seconds, or the operation to be performed in 5 seconds, the deinitialization process shall be repeated from the beginning.)

Prevention of overheated motor Software overheating prevention function is used to prevent the motor from overheating (but, EEPROM data shall be saved in ECU).

1. If the window moved by compulsion and motor have a problem, power window switch could be entering the fail safe mode for user's safety.
2. Power window operation in fail mode
   • Auto/Manual-Down function is available
   • Auto/Manual-Up function is not available

     (When Auto/Manual-up is operated, window is rising by 20 mm and stops moving.)
