WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Normal Operation and Fault Conditions
See Adaptive Steering RTT Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

If the adaptive steering message center request message is missing for less than 5 seconds, the IPC defaults the adaptive steering warning indicator to its last indication state (on or off), based upon the last message received.

If the adaptive steering message center request message is missing for 5 seconds or longer, the IPC defaults the adaptive steering warning indicator on in the amber state.
