I found some info in the Bentley Service manual relating to Replacement battery registration that states:
1.)If a higher rating battery is installed, recode CAS with correct battery specifications.
So the first thing I did was to process and read the CAS module and I found a line which read:
Since my new Federal 694RMF battery was now rated at 80ah, I changed it to 80ah.
Other options for this CAS setting are outlined below.
Obviously the first six are Wet Cell standard style of batteries and the others are the newer AGM style of battery.
The settings available are as such:
Once I recoded the CAS module with NCSExpert, I then proceeded to use the Tool32 program as described in CasperSYTFU's post above.
One other thing I also noticed is that there is a program within INPA that allows you to register your battery but it says "Stopped" in yellow at the bottom corner just before registration....>>> E90>>ENGINE>>MSD80>> Status(F5)>>PM-IBS>>B TAUSCH.
If it helps, I attached a document that shows the parameter options allowed for the various E90 modules. This is where I found Battery setting options.
