Liftgate/Liftgate Window Ajar Input
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The SJB sends a voltage signal to the liftgate ajar switch. The voltage signal passes through the liftgate ajar switch to the liftgate window ajar switch. The signal is then routed to ground.
The liftgate and the liftgate window ajar switches are wired in series and are monitored from a single circuit by the SJB . The liftgate and liftgate window ajar switches are closed when the liftgate and liftgate window are closed. When the liftgate or liftgate window is opened, the signal to ground is interrupted indicating an open liftgate or liftgate window (the SJB cannot determine which is open).
