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 Off Road Display. REFER to: Message Center - System Operation and Component Description .

If the 4x4 high/low status, vehicle pitch angle display, vehicle roll angle display and steering wheel angle messages are missing for less than 5 seconds, the IPC defaults the associated display element to the last display based on the last data received.

If the 4x4 high/low status, vehicle pitch angle display, vehicle roll angle display and steering wheel angle messages are missing for 5 seconds or longer, the IPC sets a lost communication DTC for the module in question and defaults the associated display element off or blank.
