Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2020 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The Hill Descent Control switch is used to activate and deactivate the Hill Descent Control system. When the driver presses the Hill Descent Control switch, the ATCM receives a ground signal from the switch and illuminates the Hill Descent Control indicator. The ATCM sends a hill descent control switch message to the ABS module over the HS-CAN 2. The ABS module takes the necessary action depending on the switch inputs and hill descent control message.
The Hill Descent Control switch is part of the ATCM assembly.
