Service Procedure
1. With the ignition on and vehicle not plugged into an EVSE. Start a FDRS session and navigate to Toolbox tab >
Datalogger > Secondary On-Board Diagnostic Control Module A (SOBDM) and Battery Energy Control Module
(BECM) select the BAT_CHARG_PWR PID in both modules. Are both BAT_CHARG_PWR -SOBDM and
BAT_CHARG_PWR -BECM PID showing a value 0?
(1). Yes - this article does not apply. Refer to WSM for normal diagnostics.
(2). No - proceed to Step 2.
2. 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.
3. Reprogram the PCM using the latest software level of the FDRS scan tool. Follow all on-screen instructions
carefully to complete all required coordinated module software update(s), including:
SOBDM
BECM

SOBDMB
SOBDMC
ABS module
