System Description

POWER WINDOW CONTROL SYSTEM DESCRIPTION
1. The power window control system controls the power windows' UP/DOWN function using the regulator motors.
  The main controls of this system are: the multiplex network master switch assy, which is built into the driver side door, and the power window regulator switches, which are built into the passenger side door and rear doors. Pressing each regulator switch on the multiplex network master switch assy transmits a remote UP/DOWN signal to each power window regulator switch.

FUNCTION OF MAIN COMPONENT

Component Outline	Outline
Multiplex Network Master Switch Assy	Controls window operations for all windows. Also, when window lock switch is set to lock position, window operation will only be possible for driver side power window.
Multiplex Network Switch Assy	Located on passenger side door. Regulator switch assy controls window operations for its respective window.
Power Window Regulator Switch (Rear LH, RH)	Located on rear door. Regulator switch assy controls window operations for its respective window.
Power Window Regulator Motor Assy	Receives switch signals and changes signals into motor activation. As a result, window position changes. Also, regulator motor assy uses pulse sensor (s) to detect window position.

SYSTEM FUNCTION

The power window control system has the following functions:

SYSTEM FUNCTION

Function	Outline
Manual UP/DOWN function	Function that raises window while power window switch is pulled halfway up and lowers window while switch is pushed halfway down. Window stops as soon as switch is released.
Auto UP/DOWN function	Function that enables window to be fully opened or fully closed by one full push or pull of power window switch.
Jam protection function	Function that automatically stops power window and moves it downward if object is jammed in all power windows during AUTO UP operation. During key-off operation function, jam protection function works for manual UP and AUTO UP operation. Jam protection function is available for front doors.
Remote control function	Function that allows multiplex network master switch assy to control manual and AUTO UP/DOWN operations of passenger door power window and rear door power window.
Key-off operation function	Function that makes it possible to operate power window for approximately 43 seconds after ignition switch is turned to ACC or LOCK position and both front doors are is closed.
Window lock function	Function where passenger door power window and rear door power windows' operations are disabled when window lock switch of the multiplex network master switch assy is pressed. Passenger door power window and rear door power window can be operated when window lock switch is pressed again.
Diagnosis	Function where power window switch can detect malfunctions in power window system and make diagnoses. Power window switch light starts blinking to inform driver.
Fail-safe	Function that disables power window AUTO UP/DOWN function if pulse sensor (Hall IC) or limit sensor in power window regulator motor malfunction. Manual operation is possible through power window switches.
