Service Procedure
1. Connect a battery charger 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 the 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 diagnostic scan tool.
3. Check the availability of software updates on the following modules and update as required:
(1). SQBDMC

(2). BECM

(3). Battery charger control module (BCCM)

(4). ABS
NOTE: Only one module may be updated at a time.
NOTE: Advise the customer that 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.
