Component Description: GSM
WARNING: This page is about a different car, the 2021 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
Each GSM button has five individual switch contacts that are used as input that the button has been pressed. If one switch contact is seen as nonfunctional the system will still work properly. However, if two switch contacts fail the button is no longer deemed reliable and a fault message is displayed. When park is selected above 5 mph neutral is provided along with a message in the IPC. The Brake Transmission Shift Interlock (BTSI) CAN signal is used for normal function to shift from P.
