Since the CRC-16 is 16 bits long, the look-up table is split up into two separate look-up tables. One for the high byte of the CRC regis-ter and one for the low byte of the CRC register (see Figure 3). The result from the look-up table of the high byte is XORed ...

I solved it. It is never mentioned that for the SAE J1850 the input is XORed with 0xFF. Even though the C-code Mark Adler provided states precisely that in crc ^= 0xff; however it didn't help me understand what my problem was.. It was not a bug, my code worked correctly but it was the premises I assumed.
