Service Procedure
NOTE: Some vibration felt during acceleration or throttle tip-in is characteristic to the vehicle. If a 0.5 order
engine vibration is detected at/or below 0.02g when measured at the driver seat track, this is considered a
normal characteristic of the vehicle and no repairs should be performed.
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. Is the vehicle equipped with a 3.5L PowerBoost engine?
(1). Yes - proceed to Step 3.
(2). No - download and run the "PCM - Powertrain Control Module (PCM) Software Update" application using the
latest software level of the FDRS scan tool. Repair is complete.

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.
3. Download and run the "PCM - Powertrain Control Module (PCM) Software Update" application using the latest
software level of the FDRS scan tool. Follow all on screen instructions carefully to complete all coordinated module
software updates including:
SOBDMC
ABS
BECM
