WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation and Fault Conditions
See Tow Haul Reconfigurable Telltale (RTT). Refer to Information And Message Center .
NOTE:
If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative speedometer, temperature gauge or odometer.
If the transmission tow haul mode message is missing or invalid for less than 5 seconds, the tow haul Reconfigurable Telltale (RTT) remains in the last indication state (on or off), based upon the last message received.
If the transmission tow haul mode message is missing for 5 seconds or longer, the IPC sets DTC U0100:00 in continuous memory and defaults the tow haul Reconfigurable Telltale (RTT) off.
