Principles of Operation (How Does It Work?)

Features and Operation
The Generic Electronic Module (GEM) controls the opening of the LH driver side power window (window down motion) by activating the One-Touch Down (OTD) window relay. The one-touch down feature is a GEM only function.
^ The driver side window has two downward motions: manual mode and auto mode. The down window mode is selected by pressing the driver window control switch (driver control). When the GEM detects that the driver window control switch has been pressed for a time greater than 0.4 second, it enters the manual mode. If the GEM detects that the driver window control switch was depressed between 0.04 and 0.4 second, it enters the auto mode. (The ignition switch is in the RUN or ACC position).

Auto Mode
Auto mode will be terminated when any of the follow conditions are met:
^ The LH window control switch is pushed to the up position or down position.
^ Seven seconds have elapsed since auto mode was initiated.
^ A window regulator motor stall condition is detected on the OTD sense line inputs.

One - Touch Down Relay
The GEM controls manual down and OTD window movement with the OTD relay.
The relay is activated by applying ground directly to one side of the down window relay coil, and is deactivated by removing the ground signal.
