Service Procedure
1. Connect a battery charger such as Rotunda GRX-3590 or DCA-8000 to the 12-volt battery.
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 using the latest software level of the FDRS. For hybrid and Lightning vehicles, follow all on-screen instructions carefully to complete
all required coordinated module software update(s), including:
BECM (hybrid and Lightning)
SOBDM (Lightning only)
SOBDMB (Lightning only)
SOBDMC (hybrid and Lightning)
GFM2 (Lightning only)
ABS module (hybrid and Lightning)
NOTE: For non-Lightning F-150 vehicles, 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.
