POWER WINDOW CONTROL SYSTEM DESCRIPTION
- The power window control system controls the power window UP/DOWN function using the door window regulator assembly. The main controls of this system are the multiplex network master switch, which is built into the driver side door, and the power window regulator switch, which is built into the front passenger side door.
- Pressing the power window regulator switch or either of the power window switches on the multiplex network master switch transmits an UP/DOWN signal to the corresponding door window regulator assembly.
- An ECU is built into the door window regulator assembly.

FUNCTION OF MAIN COMPONENTS

The power window control system consists of the following components:

Component	Outline
Multiplex network 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 front passenger side door. Power window regulator switch controls power window operations for its respective window.
Door window regulator assembly	Each power window switch controls power window operations for its respective windows. Receives power window switch signals and activates door window regulator assembly to change window position. Uses Hall IC in door window regulator assembly with ECU to detect window position and jamming.

SYSTEM FUNCTION

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 up and lowers the window while it is pushed halfway down. The window stops when the switch is released.
AUTO UP/DOWN function	Function that enables a window to be fully opened or closed by one full push or pull of the power window switch.
Remote UP/DOWN function	Function that allows the multiplex network master switch to control the front passenger side power window.
Window lock function	Function where the front passenger side power window regulator switch operation is disabled when the window lock switch is pressed. The front passenger side power window regulator switch can be operated when the window lock switch is pressed again.
Key-off operation function	Using the multiplex network master switch, the power windows for both seats can be operated after the power switch is turned off. After the driver door is opened and closed, the power windows cannot be operated. Using the power window regulator switch, the power window for the passenger seat can be operated after the power switch is turned off. After the driver door is opened and closed, the power windows cannot be operated. The power windows cannot be operated if approximately 45 seconds have elapsed after turning the power switch off. However, if a window operation is in progress at 45 seconds, the operation will continue until the open/close operation is completed.
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.
Diagnosis	Function where ECU in the door window regulator assembly detects malfunctions in the power window system and makes a diagnosis. The power window switch light blinks to inform the driver of the malfunction.
Fail-safe	If the pulse sensor(s) [Hall IC(s)] in the door window regulator assembly malfunctions, the power window AUTO UP/DOWN function is disabled.
