CAN checksum algorithm

Question

I am trying to caclulate a checksum algorithm. D0 is CRC, D1 to D2 is data. Maybe someone can help me with algorithm for checksum calculation?

D0  D1  D2  D3
68  00  01  00
74  00  03  00
DD  01  01  00
C1  01  03  00
2D  02  01  00
31  02  03  00
98  03  01  00
84  03  03  00
E2  04  01  00
FE  04  03  00
57  05  01  00
4B  05  03  00
A7  06  01  00
BB  06  03  00
12  07  01  00
0E  07  03  00
53  08  01  00
4F  08  03  00
E6  09  01  00
FA  09  03  00
16  0A  01  00
0A  0A  03  00
A3  0B  01  00
BF  0B  03  00
D9  0C  01  00
C5  0C  03  00
6C  0D  01  00
70  0D  03  00
9C  0E  01  00
80  0E  03  00

If you have more messages you could try this for reverse engineering checksums: https://github.com/laurenlabell/checksum_finder

For CRCs there's a tool called CRCRevEng which is harder to use, but can tackle CRCs.
