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 (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.
(b) The power window control system (for back door power window) controls the power window open/close function using the power window regulator motor.
The main control of this system is the back door power window regulator switch assembly.*1

Auto up and down function (for Front Door Only) |
Function that enables the driver door or front passenger door window to be fully opened or closed by one full pull or push of the power window regulator master switch assembly or front 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. |
Catch protection function |
Function that automatically stops the power window if a foreign object gets caught in the door window during auto down or manual down 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 |
HINT: Even if the driver door or passenger door is opened during automatic 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) detect a malfunction in the system. |
Fail-safe |
Function to disable part of the 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. |
