Normal Operation

WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

If the power liftgate is operated from the power liftgate control switch (instrument panel), circuit CPR63 (GY/YE) is grounded by the open/close switch, which signals the Liftgate/Trunk Module (LTM) of the open/close request. If the power liftgate is operated from the rear switch (quarter trim panel), circuit CPR70 (GN) is grounded by the rear switch through circuit GD149 (BK/GY). If the power liftgate is operated from the liftgate handle, the Smart Junction Box (SJB) sends a voltage signal to the LTM  through circuit CPL10 (GN/WH).
