Sounds like FA string in CAS is ruined. Why not try to read it from alternative unit? Or make FA manually.

P.S. Are you using ICOM or crap KDCAN to read this? If KDCAN could also be FA string too long (if car is EXTREMELY options rich) for crap firmware to handle...

I use ICOM. I tried to read FA from another block, too, an error.
