This may be due to the software level of the PCM. To correct this condition, follow the Service Procedure to reprogram the PCM to the latest software level via the FDRS.   Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria: • 2024 Nautilus equipped with an FHEV powertrain • Illuminated MIL with DTC P0300, P0316 and/or P051B stored in the PCM Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Emissions Warranty/Service Part Warranty (SPW)/Service Part New Vehicle (SPNV)/Extended Service Plan (ESP) coverage.

NOTE: To prevent the battery saver mode from activating on the vehicle, make sure the negative cable of the charger is installed on a chassis or engine ground, and not the 12-volt battery negative terminal. Do not have the vehicle plugged into high voltage battery charger during programming. This can cause incorrect module programming. Make sure only the 12-volt battery charger is installed. 2. Reprogram the PCM and SOBDMC using the latest level software level of the FDRS scan tool. Follow all on-screen instructions carefully to complete all coordinated module software updates.   NOTE: Advise the customer this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.   © 2024 Ford Motor Company All rights reserved.
