Yesterday, I tried to import a J1939 dbc but I had an issue. I have 2 IDs, CEFD1EF and DEFD1EF, with the PGN EF00 and 1EF00. When I try to import these 2 messages, I get a random result: I sometimes obtain 2 messages with the data mixed on eachother, or 1 message with the data of the 2 messages, and the PGN read by Iqan Design is always EF00 (61184).
The work around I found is to import the messages with PGN 1EF00 and change the PGN imported from 61184 to 126720, then import the message with PGN EF00.
I concluded that the DP bit is not read or not correctly imported. In your opinion, is that an importation bug or a bad DBC configuration?
