POWER WINDOW CONTROL SYSTEM(for Models with Jam Protection Function on 4 Windows) SYSTEM DESCRIPTION
POWER WINDOW CONTROL SYSTEM DESCRIPTION
The power window control system controls the power window operation using the power window regulator motors. The main controls of this system are the power window regulator master switch assembly (mounted on the driver door), power window regulator switch assembly (mounted on the front passenger door) and rear power window regulator switch assemblies (mounted on the rear doors). Operating a window switch results in electrical power being transmitted to the corresponding power window regulator motor.
FUNCTION OF MAIN COMPONENTS
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 the lock switch is set to the lock position, window operation will be possible for all windows.
Power Window Regulator Switch Assembly
Located on the front passenger door.
Controls front passenger window operation.
Rear Power Window Regulator Switch Assembly
LH Door
RH Door
Located on the rear doors.
Each switch controls window operation for its respective window.
Front Door Window Regulator Assembly
Rear Door Window Regulator Assembly
Receives switch signals and changes signals into motor activation. As a result, the window position changes.
Uses the Hall-ICs built into the regulator motor and the power window ECUs to detect the window position and jamming.
SYSTEM FUNCTION
The power window control system has the following functions:
Function
Outline
Manual up and down function
Function that causes the window to go up while the power window switch is being pulled halfway up and to go down while it is being pushed halfway down. The window stops as soon as the switch is released.
Auto up and down function
Function that enables the window of each door to be fully opened or closed by one full pull or push of the power window regulator master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly.
Window lock function
Function that disables the power window regulator switch assembly and rear power window regulator switch assembly operations when the window lock switch is pressed.
The power window regulator switch assembly and rear power window regulator switch assembly can be operated when the window lock switch is pressed again.
Jam protection function
Function that automatically stops the power window and moves it downward if a foreign matter gets jammed in the door window during auto up or manual up operation.
Remote control function
Function that allows the power window regulator master switch assembly to control manual and auto up and down operations of the front passenger door window and rear door windows.
Key-off operation function
Function that makes it possible to operate all power windows for approximately 43 seconds after the ignition switch is turned off when the driver door or front passenger door has not been opened.
When 43 seconds have elapsed, or the driver door or front passenger door is opened after the ignition switch is turned off, the key-off operation function will be disabled.
Tip:Even if the driver door or front passenger door is opened during auto window operation while the key-off operation function is on, the window will continue operating.
Diagnosis
Function that allows diagnosis of the power window control system if any of the power window ECUs (built into each power window regulator motor assembly) detects a malfunction in the system.
Fail-safe
Function to disable part of power window control system functions if the pulse sensor in the power window regulator motor has a malfunction.
Auto up and down function and remote control function are disabled.
