SYSTEM DESCRIPTION
1. POWER WINDOW CONTROL SYSTEM DESCRIPTION
(a) 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, which is mounted on the driver side door, and the power window regulator switches, which are mounted on the front passenger side door and rear doors. Operating a window switch results in electrical power being transmitted to the corresponding power window regulator motor.
2. FUNCTION OF MAIN COMPONENTS
The power window control system consists of the following components:

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 pushed halfway down. The window stops as soon as the switch is released. |
All door auto up-and-down function |
Function that enables windows of all doors to be fully opened or closed by one full pull or push of the power window regulator master switch assembly or power window regulator switch assembly. |
Window lock function |
|
Jam protection function |
Function that automatically stops power window and moves it downward if a foreign object gets jammed in door window during auto up and 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 |
|
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) detect a malfunction in the system. |
Fail-safe |
A fail-safe function to disable a part of power window functions if the pulse sensor in the power window motor has a malfunction. Auto up-and-down function and remote control function are disabled. |
