DOWN OPERATION
The Generic Electronic Module (GEM) controls the opening of the LF driver side power window (window down motion) by activating the one touch down window relay.

There are two modes of window down operation, manual and auto mode. The manual mode is selected by pressing the LF window switch to the first (down) position. In manual mode the window will move downward only while the switch is depressed. When the LF window switch is pressed to the second (down) position, it enters auto mode and the window will open completely with just a momentary press of the switch.

Manual Mode
When the LF window switch is pressed to the first (down) position, the GEM will activate the One Touch Down Relay until one of the following conditions is met:
- The LF window regulator switch is no longer in the first down position.
- The LF window regulator switch is pushed to the AUTO DOWN position causing the window to enter Auto Mode.

Feature inputs:
- LF window regulator control switch inputs.

Feature outputs:
- Down window relay coil output (grounded when activated, open circuit when deactivated).

NOTE: The delayed accessory relay must be active for the window system to operate (grounded when activated, open circuit when deactivated).

Auto Mode
The AUTO DOWN feature is activated when the LF window regulator control switch is pressed to the second down position. The GEM will activate the One Touch Down Relay until one of the following conditions is met:
- The LF regulator control switch is pushed to the UP position.
- The LF regulator control switch is released (OFF position) and then moved to the down position (first detent) or AUTO position (second detent).
- Seven seconds have elapsed since the Auto Mode was initiated.
- A window regulator electric drive stall condition is detected on the one touch down sense line inputs.

Feature inputs:
- LF window regulator control switch input.
- Auto Down sense lines, high and low (voltage difference corresponds to window motor current).

Feature outputs:
- One Touch Down window relay coil output (grounded when activated, open circuit when deactivated).

NOTE: The delayed accessory relay must be active for the window system to operate (grounded when activated, open circuit when deactivated).

UP OPERATION

NOTE: The delayed accessory relay must be active for the window system to operate (grounded when activated, open circuit when deactivated).

The UP window operation is not controlled by the GEM. The feature is activated when the delayed accessory is active and the LF window regulator control switch is pressed to the UP position. The switch provides delayed accessory power to one side of the motor and ground to the other side through the one touch down relay. The one touch down relay is not active when the LF regulator control switch is in the UP position.
