ICOM A2 ISTA-P central encoding code not be read (fixed)

There is only a problem with connection via ISTA-P software on my PC
There is no problem with ISTA-D which everything is fine. Read data etc.
Car is F30 320d 2012 year
Here, I explain all step by step to end up the trouble.

Before starting vehicle programming, ensure that the basic requirements for error-free programming are satisfied. See ISTA/P under documentation “Preparation and follow up of vehicle programming”.

Vehicle : F30. Vehicle access being checked…

The vehicle order central encoding code not be read from the vehicle. The selected model series group is “F020”. This selection might have been incorrect.

The vehicle order could not be read from the vehicle. Import of vehicle order required.

I select “Print Screen” or “Prnt Scrn” on keyboard to take screenshot and then paste in program like Paint for better images, but images are not unreadable


Then i calculate FP in E-sys and see which VO incompatible with current psdzdata. i’ve tried this matter and there are obsoleted VO (in a forum bro’s case, 620 is valid before but obsoleted now, remove it and fixed)


That is the easiest to test. Manually search all H-words, E-words, and W Selectors; however, to decrypt FAFP first. One can load FA, calculate FP, and E-sys will accept or ID exactly which values are not found in FA2FP table.

FYI: to decrypt FAFP files, F020 is fafp_000009b7.fap.xxx_xxx_xxx and F030 is fafp_00000a6a.fap.xxx_xxx_xxx.
