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

FUNCTION OF MAIN COMPONENT

Component	Outline
Multiplex Network Master Switch Assembly	Controls power window operation for all seats. When the lock switch is set to the lock position, window operation will be possible only for the driver door power window. HINT: Even when the window lock switch of the multiplex network master switch assembly is pushed in, remote manual up and down and auto up and down functions can be operated.
Multiplex Network Switch Assembly (Passenger, Rear LH, Rear RH)	Located on each door. The switch controls window operations for its respective window.
Power Window Regulator Motor Assembly	Receives switch signals and changes signals into motor activation. As a result, window position changes. Also, regulator motor assembly uses pulse sensor(s) to detect window position.

SYSTEM FUNCTION

The power window control system has the following functions:

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 the 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 manual and AUTO UP operation. Jam protection is available for all doors.
Remote control function	Function that allows multiplex network master switch assembly to control manual and AUTO UP/DOWN operations of passenger door power window and rear door power windows.
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 closed.
Window lock function	Function where passenger door power window and rear door power windows operations by pressing multiplex network switch on each door are disabled when window lock switch of the multiplex network master switch assembly 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.
