After studying the 2012 EVB manual, specifically P33E6 logic for diagnostics/repairs (pg 138-141 - at least for my 2012), this seems to be the logic:
1. DTC P33E6 must be Registered -otherwise no further action is required
2. DTC's P0A1F,P3062 in conjuction with P33E6 is a battery controller issue
3. DTC P33ED in conjuction with P33E6 is a "battery parallel diagnostic"??
4. Otherwise the "cell voltage deviation diagnostic" procedure is followed.
5. The various procedures that followed seem quite convoluted/unclear logic, however, it is clear that the 3.712 mV is only used as the required value to discharge the minimum voltage cell (via consult) to below the 3.712 threshold before further testing with Consult - don't believe it has any other significance as the battery is simply discharged by turning on all big users until the minimum cell is 3.712 mv or below.
6. There are many steps that follow using Consult to confirm the cell/module to be replaced AND to check all other internal battery components - I'd guess to ensure against any false Consult results and/or weak/damaged hardware components.
7. Replacement of the bad module and any faulty wiring/hardware. Interesting that if there is evidence of "condensate", the battery is simply replaced - no further explanation. I'm not sure of the logic because it seems the modules are replaced on two separate parts of the procedures - that makes no sense.
Maybe someone that has used Consult to do an actual module replacement can explain the actual logic flow of steps 2-10! It could also be that the later model year procedures have been revised? Maybe I missed something.
Bottom line to me is that unless you have "thrown" DTC P33E6, there is no bad cell replacement under the manufacturer's warranty against any defects.
