POWER WINDOW CONTROL SYSTEM SYSTEM DESCRIPTION

POWER WINDOW CONTROL SYSTEM DESCRIPTION

• The power window control system controls the power window UP/DOWN function using the power window regulator motor. The main controls of this system are the power window regulator master switch, which is built into the driver door, and the power window regulator switches, which are built into the front passenger door and rear doors.

• Pressing the power window regulator switch or either of the power window switches on the power window regulator master switch transmits an UP/DOWN signal to the corresponding power window regulator motor.

• An ECU is built into the front power window regulator motor (driver side).

FUNCTION OF MAIN COMPONENTS

1. The power window control system consists of the following components:

   Component	Outline
   Power window regulator master switch assembly	Controls power window operation for all windows. When window lock switch is set to lock position, window operation will only be possible with driver side switch.
   Power window regulator switch assembly	Located on the front passenger door and rear doors. Each of the power window regulator switches controls power window operations for its respective window.
   Front door window regulator assembly (driver side)	Uses Hall IC in regulator motor with ECU to detect window position and jamming.
   Front door window regulator assembly (front passenger side)	Receives power window switch signals and activates motor to change window position.
   Rear door window regulator assembly LH or RH*	Receives power window switch signals and activates motor to change window position.

   
   

   • *: w/ Rear Power Window

SYSTEM FUNCTION

1. The power window control system has the following functions:

   Function	Outline
   Manual UP/DOWN function	Function that raises the window while the power window switch is pulled halfway (driver side) or full (except driver side) up and lowers the window while it is pushed halfway (driver side) or full (except driver side) down. The window stops when the switch is released.
   AUTO UP/DOWN function	Function that enables the driver door window to be fully opened or closed by one full push or pull of the power window regulator master regulator switch.
   Remote control function	Function that allows the power window regulator master switch to control MANUAL UP/DOWN operations of the front passenger and rear power windows.
   Window lock function	Function where the front passenger and rear power window regulator switches operation is disabled when the window lock switch is pressed. The front passenger and rear power window regulator switches can be operated when the window lock switch is pressed again.
   Key-off operation function	Function that makes it possible to operate all power windows for approximately 45 seconds after the power switch is turned off when the driver door or front passenger door has not been opened. When 45 seconds have elapsed, or the driver door or front passenger door is opened after the power switch is turned off, the key-off operation function will be disabled. Tech Tips Even if the driver door or passenger door is opened during AUTO operation while the key-off operation function is on, the window will continue operating.
   Jam protection function	Function that automatically stops a power window and moves it downward if an object is jammed in the power window. Jam protection function works for AUTO UP and MANUAL UP operation of the driver door power window.
   Diagnosis	Function where ECU in the power window regulator motor (driver side) detects malfunctions in the power window system and makes a diagnosis. The power window regulator switch light blinks to inform the driver of the malfunction.
   Fail-safe	If the pulse sensor(s) (Hall IC(s)) in the power window regulator motor (driver side) malfunctions, the power window AUTO UP/DOWN function is disabled.
