Repair/Claim Coding
Causal Part:

7P120

Condition Code: 04

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. Download and run the "SOBDMC - Secondary On-Board Diagnostic Control Module C (SOBDMC) Software
Update" application in the FDRS scan tool. Follow all on-screen instructions carefully to complete all required
coordinated module software update(s), including:
PCM
BECM
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.
