Registering a new battery in newer Bimmers where INPA does not

There are two steps to registering a new battery:
1. Make sure the car is coded for the correct Amps/Hours rating of your new battery
and type.
2. Register the new battery with the ECU. For the first step you will need to know
the Amps/Hours (AH) rating of your new battery. If you don't know the AH rating, you
can calculated it based off of the Reserve Capacity rating, which is generally easier to
come by. Instructions to calculate below:
Calculating AH rating based off of the Reserve Capacity rating:
Amp/Hours = (Reserve Capacity / 2) plus 16
(i.e: If your battery had a
Reserver Capacity of 100, you would get 66 AH rating)
Choose the AH ratings option closest to your batter for this CAS (Available
setting are outlined below)
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:
If you are replacing your battery with the same type and rated battery
that your car is coded for, you can skip the Coding the Battery Ah
Setting in the CAS module section and skip down to the Registering the
New Battery section.
Coding the Battery Ah Setting in the CAS Module
Just to avoid any mistake close NCS we are going to start from the beginning.
2. Load NCS >File>load profile> “FSW PSW MAN”
3. F1>F3>select your chassis>select “CAS”
4. Press F6 for back
5. Press F4 to select a specific module “Process ecu” then you get a list of all modules on your car
will and may be different.
7. Select “CAS”
then select “READ ECU” this is going to create another FSW_PSW.TRC
file but only
with the values on for the module we select.
8. Select “READ ECU” this will read all the values from the specific module and place ten in the file
stated above. You will get a screen like this.. you can close it.
10. Leave ncs open and head to the “work” folder.
11. Open the FSW_PSW.TRC file with notepad
12. File>save as FSW_PSW.MAN (be sure to select
“save as type” to all files so that it will accept our
“.MAN” extension. If you fail to do so it will just save it as a text file
13. The “FSW PSW MAN” profile that we used is going to use this “FSW_PSW.MAN” file .
where we are going to make any changes and then NCS will write this to ECU.
14. Open the file we just saved with notepad will look like this.
this is
16. Search for the option “KLASSE_BATTERIE” and change the value from it current setting closest
match the rating of your battery (ie: "90ah" to "70ah")
17. File >Save
18. Back to NCS now hit F5 for basic functions
19. Select “coapiReadSgGetFswPsw” and ok..
you are basically telling NCS to read all the values
from your file. You will see a screen similar to this just press ok.
21. Then you should get this.
23. Press ok.
Ok now take a look where it says “JOBNAME = CODIERDATEN_LESEN”
25. We need to change that to a coding function because we want to write the changes to the
26. Select F2 “job”
select SG_CODIEREN and press ok
27. Then press F3 to execute the job. Will gray out for some time..
now you will see this . notice the
“coding ended’ message
29. Assuming no errors.. The battery rating should now be updated in the system.
Registering the New Battery
Open up Toolset 32 (TOOL32.EXE under C:\EDIABAS\bin folder):
Note: For those of you that this is the first time using the EDIABAS Tool32 program, if when
you open it the menu appears in German with a German flag in the title bar, click on Konfiguration in
them menu bar, then click ToolSet, and then click the check box next to Englische Version in the popup
window to get the English version.
1. Click File, then Load SGBD, Group file from the menu and open MSD80.prg
2. Look up steuern_batterietausch_registri. (near bottom of job list)
It may alternatively be under MSV70.prg or MSV80.prg from the previous step.
3. Go to Jobs menu
4. Select Start Job once only from the Job menu.
5. This job runs very quickly, look in the Results window for the line JOB_STATUS = OKAY (I have
highlighted mine above). If you see that line, congrats - your battery registration is complete!
